----------------------- 已知漏洞和当前工作 --------------------------
Patch to make virtcol([123, '$']) do the right thing. (Michael Schaap)
Insert mode completion: CTRL-N and CTRL-P work differently and they both don't
work as expected. (Bernhard Walle, 2007 Feb 27)
When 'rightleft' is set the completion menu is positioned wrong. (Baha-Eddine
MOKADEM)
glob() doesn't work correctly with single quotes and 'shell' set to /bin/sh.

25)
Replace ccomplete.vim by cppcomplete.vim from www.vim.org? script 1520
(Martin Stubenschrott)
ctags -R --c++-kinds=+p --fields=+iaS --extra=+q .
Making the German sharp s uppercase doesn't work properly: one character less

Also: latin2 has the same character but it isn't uppercased there.
Mac: After a ":vsplit" the left scrollbar doesn't appear until 'columns' is
changed or the window is resized.

Using Aap to build Vim: add remarks about how to set personal preferences.
Example on http://www.calmar.ws/tmp/aap.html
GTK: 'bsdir' doesn't work. Sometimes get a "gtk critical error".
Moved some code to append file name to further down in gui_gtk.c
gui_mch_browse(), but "last" value of 'bsdir' still doesn't work.
C syntax: "#define x {" The macro should terminate at the end of the line,
not continue in the next line. (Kelvin Lee, 2006 May 24)
C syntax: {} inside () causes following {} to be highlighted as error.
(Michalis Giannakidis, 2006 Jun 1)
Gnome improvements: Edward Catmur, 2007 Jan 7
Also use Save/Discard for other GUIs
New PHP syntax file, use it? (Peter Hodge)
'foldcolumn' in modeline applied to wrong window when using a session. (Teemu
Likonen, March 19)
Syntax highlighting wrong for transparent region. (Doug Kearns, 2007 Feb 26)

Redraw problem in loop. (Yakov Lerner, 2006 Sep 7)
Add option settings to help ftplugin. (David Eggum, 2006 Dec 18)
Use new dutch wordlist for spelling? http://www.opentaal.org/
See remarks from Adri, 2007 Feb 9.
When opening quickfix window, disable spell checking?
Windows 98: pasting from the clipboard with text from another application has
a trailing NUL. (Joachim Hofmann) Perhaps the length specified for CF_TEXT
isn't right?
Win32: When 'encoding' is "latin1" 'ignorecase' doesn't work for characters
with umlaut. (Joachim Hofmann) toupper_tab[] and tolower_tab[] are not filled
properly?
Completion: Scanning for tags doesn't check for typed key now and then?
Hangs for about 5 seconds. Appears to be caused by finding include files with
"foo/**" in 'path'. (Kalisiak, 2006 July 15)
Completion: When 'completeopt' has "longest" and there is one match the
message is "back at original" and typing a char doesn't leave completion mode.
(Igor Prischepoff, 2006 Oct 5)
Completion: When using CTRL-X O and there is only "struct." before the cursor,
typing one char to reduce the matches, then BS completion stops. Should keep
completion if still no less than what we started with.
Completion: don't stop completion when typing a space when completing full
lines? Also when completing file names? Only stop completion when there are
no matches?
After using BS completion only stops when typing a space. Many people want to
stop at non-word characters, e.g., '('. Add an option for this? Or check
vim_iswordc() before calling ins_compl_addleader()?
searchpos() doesn't use match under cursor at start of line. (Viktor
Kojouharov, 2006 Nov 16)
When FEAT_BYTEOFF is defined but FEAT_NETBEANS_INTG is not compiling fails.
Add FEAT_BYTEOFF to the check at line 1180 in feature.h
Color for cUserLabel should differ from case label, so that a mistake in a
switch list is noticed:
switch (i)
{
case 1:
foobar:
}
":s" command removes combining characters. (Ron Aaron, 2006 May 17, 2006 Dec 7)
Look at http://www.gtk-server.org/ . It has a Vim script implementation.
Changes for Win32 makefile. (Mike Williams, 2007 Jan 22, Alexei Alexandrov,
2007 Feb 8)

New version: http://members.tcnet.ch/michaelis/vim/patches.zip (also for other
patches by Mathias, see mail Feb 22)
Win32: compiling with normal features and OLE fails. Patch by Mathias

Patch that includes this and does more by George Reilly, 2007 Feb 12
Win16: include patches to make Win16 version work. (Vince Negri, 2006 May 22)
Win32: after "[I" showing matches, scroll wheel messes up screen. (Tsakiridis,
2007 Feb 18)
Win32: using CTRL-S in Insert mode doesn't remove the "+" from the tab pages
label. (Tsakiridis, 2007 Feb 18)
Win32: remote editing doesn't work when the current directory name contains
"[]". (Ivan Tishchenko, 2007 March 1)
Win64: diff.exe crashes on Win64. (Julianne Bailey, 2006 Dec 12)
Build another diff.exe somehow?
Win64: Seek error in swap file for a very big file (3 Gbyte). Check storing
pointer in long and seek offset in 64 bit var.
When doing "gvim --remote-tab foo" while gvim is minimized the tab pages line
only shows the current label, not the others.
Problem finding swap file for recovery. (Gautam Iyer, 2006 May 16)
When setting 'keymap' twice the b:keymap_name variable isn't set. (Milan
Berta, 2007 Mar 9) Has something to do with 'iminsert'.
Problem with CursorHoldI? (Max Dyckhoff, 2006 Nov 10)
UTF-8: mapping a multi-byte key where the second byte is 0x80 doesn't appear
to work. (Tony Mechelynck, 2007 March 2)
The str2special() function doesn't handle multi-byte characters properly.
Patch from Vladimir Vichniakov, 2007 Apr 24.
find_special_key() also has this problem.
In debug mode, using CTRL-R = to evaluate a function causes stepping through
the function. (Hari Krishna Dara, 2006 Jun 28)
":let &shiftwidth = 'asdf'" doesn't produce an error message.
C++ indenting wrong with "=". (James Kanze, 2007 Jan 26)
"zug" reports wrong file. problem with Namebuff? (Lawrence Kesteloot, 2006 Sep
10)
":lockvar" should use copyID to avoid endless loop.
Patch to use xterm mouse codes for screen. (Micah Cowan, 2007 May 8)
Gvim: dialog for closing Vim should check if Vim is busy writing a file. Then
use a different dialog: "busy saving, really quit? yes / no".
Win32: editing remote file d:\a[1]\aa.txt doesn't work. (Liu Yubao, 2006 May
29)
"zw" doesn't appear to work. (Luis A Florit, 2006 Jun 23, 24)
"dw" in a line with one character deletes the line. Vi and nvi don't do this.
Is it intentional or not? (Kjell Arne Rekaa)
Check other interfaces for changing curbuf in a wrong way. Patch like for
if_ruby.c.
Spell checking in popup menu: If the only problem is the case of the first
character, don't offer "ignore" and "add to word list".
":helpgrep" should use the directory from 'helpfile'.
The need_fileinfo flag is messy. Instead make the message right away and put
it in keep_msg?
More-prompt is skipped when doing this; (Randall W. Morris, Jun 17)
:au
<Space>
b
<Space>
Editing a file remotely that matches 'wildignore' results in a "no match"
error. Should only happen when there are wildards, not when giving the file
name literally, and esp. if there is only one name.
When 'expandtab' is set then a Tab copied for 'copyindent' is expanded to
spaces, even when 'preserveindent' is set. (Alexei Alexandrov, Mar 7)
Test 61 fails sometimes. This is a timing problem: "sleep 2" sometimes takes
longer than 2 seconds.
VMS: while editing a file found in complex, Vim will save file into the first
directory of the path and not to the original location of the file.
(Zoltan Arpadffy)
input() completion should not insert a backslash to escape a space in a file
name?
getpos()/setpos() don't include curswant. getpos() could return a fifth
element. setpos() could accept an optional fifth element.
Ruby completion is insecure. Can this be fixed?
":confirm w" does give a prompt when 'readonly' is set, but not when the file
permissions are read-only. Both can be overruled by ":w!" thus it would be
logical to get a prompt for both. (Michael Schaap)
When 'backupskip' is set from $TEMP special characters need to be escaped.
(patch by Grembowietz, 2007 Feb 26, not quite right)
Another problem is that file_pat_to_reg_pat() doesn't recognize "\\", so "\\("
will be seen as a path separator plus "\(".
":python os.chdir('/tmp')" makes short buffer names invalid. (Xavier de Gaye)
Check directory and call shorten_fnames()?
aucmd_prepbuf() should also use a window in another tab page.
Substituting an area with a line break with almost the same area does change
the Visual area. Can this be fixed? (James Vega, 2006 Sept 15)
Windows installer could add a "open in new tab of existing Vim" menu entry.
:s/e/E/l not only lists but also shows line number. Is that right?
(Yakov Lerner, 2006 Jul 27)
GUI: When combining fg en bg make sure they are not equal.
Use different pt_br dictionary for spell checking. (Jackson A. Aquino, 2006
Jun 5)
Mac: Using gvim: netrw window disappears. (Nick Lo, 2006 Jun 21)
When 'bomb' is set or reset the file should be considered modified. (Tony
Mechelynck) Handle like 'endofline'.
Add an option to specify the character to use when a double-width character is
moved to the next line. Default '>', set to a space to blank it out. Check
that char is single width when it's set (compare with 'listchars').
Update main.aap for installing on the Mac.
The generated vim.bat can avoid the loop for NT. (Carl Zmola, 2006 Sep 3)
Session file creation: 'autochdir' causes trouble. Keep it off until after
loading all files.
C completion: doesn't work after aa[0]->, where aa is an array of structures.
(W. de Hoog, 2006 Aug 12)
The spellfile plugin checks for a writable "spell" directory. A user may have
a writable runtime directory without a "spell" directory, it could be created
then.
These two abbreviations don't give the same result:
let asdfasdf = "xyz\<Left>"
cabbr XXX <C-R>=asdfasdf<CR>
cabbr YYY xyz<Left>
Michael Dietrich: maximized gvim sometimes displays output of external command
partly. (2006 Dec 7)
In FileChangedShell command it's no longer allowed to switch to another
buffer. But the changed buffer may differ from the current buffer, how to
reload it then?
New syntax files for fstab and resolv from Radu Dineiu, David Necas did
previous version.
For Aap: include a config.arg.example file with hints how to use config.arg.
Linux distributions:
- Suggest compiling xterm with --enable-tcap-query, so that nr of colors is
known to Vim. 88 colors instead of 16 works better. See ":help
xfree-xterm".
- Suggest including bare "vi" and "vim" with X11, syntax, etc.
Completion menu: For a wrapping line, completing a long file name, only the
start of the path is shown in the menu. Should move the menu to the right to
show more text of the completions. Shorten the items that don't fit in the
middle?
When running inside screen it's possible to kill the X server and restart it
(using pty's the program can keep on running). Vim dies because it looses the
connection to the X server. Can Vim simply quit using the X server instead of
dying? Also relevant when running in a console.
Accessing file#var in a function should not need the g: prepended.
When ":cn" moves to an error in the same line the message isn't shortened.
Only skip shortening for ":cc"?
Win32: The matchparen plugin doesn't update the match when scrolling with the
mouse wheel. (Ilya Bobir, 2006 Jun 27)
Write "making vim work better" for the docs (mostly pointers): *nice*
- sourcing $VIMRUNTIME/vimrc_example.vim
- setting 'mouse' to "a"
- getting colors in xterm
- compiling Vim with X11, GUI, etc.
Problem with ":call" and dictionary function. Hari Krishna Dara, Charles
Campbell 2006 Jul 06.
Syntax HL error caused by "containedin". (Peter Hodge, 2006 Oct 6)
GTK: When maximizing Vim the result is slightly smaller, the filler border is
not there, and the "maximize" button is still there. Clicking it again does
give a maximized window. (Darren Hiebert)
Problem is that gui_mch_set_text_area_pos() is invoked to change the text area
size, which causes the toplevel window to resize. When doing this while the
size is already right the filler remains there.
Detect using the maximize button (GdkWindowState bit
GDK_WINDOW_STATE_MAXIMIZED) and set it again?
Another resizing problem when setting 'columns' and 'lines' to a very large
number. (Tony Mechelynck, 2007 Feb 6)
Problem with using :redir in user command completion function? (Hari Krishna
Dara, 2006 June 21)
After starting Vim, using '0 to jump somewhere in a file, ":sp" doesn't center
the cursor line. It works OK after some other commands.
Screen redrawing when continuously updating the buffer and resizing the
terminal. (Yakov Lerner, 2006 Sept 7)
Win32: Is it possible to have both postscript and Win32 printing?
Does multi-byte printing with ":hardcopy" work? Add remark in documentation
about this.
'thesaurus' doesn't work when 'infercase' is set. (Mohsin, 2006 May 30)
There should be something about spell checking in the user manual.
Check: Running Vim in a console and still having connect to the X server for
copy/paste: is stopping the X server handled gracefully? Should catch the X
error and stop using the connection to the server.
Problem with 'cdpath' on MS-Windows when a directory is equal to $HOME. (2006
Jul 26, Gary Johnson)
In the Netbeans interface add a "vimeval" function, so that the other side can
check the result of has("patch13").
":py" asks for an argument, ":py asd" then gives the error that ":py" isn't
implemented. Should already happen for ":py".
Add command modifier that skips wildcard expansion, so that you don't need to
put backslashes before special chars, only for white space.
Win32 GUI: confirm() with zero default should not have a choice selected.
Win32: When the GUI tab pages line is displayed Vim jumps from the secondary
to the primary monitor. (Afton Lewis, 2007 Mar 9) Old resizing problem?
GTK GUI: When the completion popup menu is used scrolling another window by
the scrollbar is OK, but using the scroll wheel it behaves line <Enter>.
"cit" used on <foo></foo> deletes <foo>. Should not delete anything and start
insertion, like "ci'" does on "". (Michal Bozon)
Allow more than 3 ":match" items.
The magic clipboard format "VimClipboard2" appears in several places. Should
be only one.
It's difficult to debug numbered functions (function in a Dictionary). Print
the function name before resolving it to a number?
let d = {}
fun! d.foo()
echo "here"
endfun
call d.foo(9)
Add a mark for the other end of the Visual area (VIsual pos). '< and '> are
only set after Visual moded is ended.
Small problem displaying diff filler line when opening windows with a script.
(David Luyer, 2007 Mar 1 ~/Mail/oldmail/mool/in.15872 )
When pattern for ":sort" is empty, use last search pattern. Allows trying out
the pattern first. (Brian McKee)
Is it allowed that 'backupext' is empty? Problems when backup is in same dir
as original file? If it's OK don't compare with 'patchmode'. (Thierry Closen)
Patch for supporting count before CR in quickfix window. (AOYAMA Shotaro, 2007
Jan 1)
Patch for adding ":lscscope". (Navdeep Parhar, 2007 Apr 26; update Apr 28)
Patch for improving regexp speed by not freeing memory. (Alexei Alexandrov,
2007 Feb 6)
xterm should be able to pass focus changes to Vim, so that Vim can check for
buffers that changed. Perhaps in misc.c, function selectwindow().
Xterm 224 supports it!
Omni completion takes the wrong structure for variable arguments. (Bill
McCarthy, 2007 Feb 18)
When completing from another file that uses a different encoding completion
text has the wrong encoding. E.g., when 'encoding' is utf-8 and file is
latin1. Example from Gombault Damien, 2007 Mar 24.
Completing ":echohl" argument should include "None". (Ori Avtalion)
Vim 7.2:
- Search offset doesn't work for multibyte character. Patch from Yukihiro
Nakadaira, 2006 Jul 18.
Changes the offset from counting bytes to counting characters.
- Rename the tutor files from tutor.gr.* to tutor.el.*. Greece vs Greek.
Make all tutor files available in utf-8.
- Remove ! for ":cgetfile" and ":lgetfile". (patch from Yegappan Lakshmanan,
2007 Mar 9)
- Add blowfish encryption. Openssl has an implementation. Also by Paul
Kocher (LGPL), close to original. Mohsin also has some ideas.
Take four bytes and turn them into unsigned to avoid byte-order problems.
Need to buffer up to 7 bytes to align on 8 byte boundaries.
- Rename doc/sql.vim doc/ft_sql.vim.
- Change "command-line" to "[Command Line]" for the command line buffer
name in ex_window().
- Move including fcntl.h to vim.h, before O_NOFOLLOW, and remove it from all
.c files.
- ":{range}source": source the lines from the file.
You can already yank lines and use :@" to execute them.
Most of do_source() would not be used, need a new function.
It's easy when not doing breakpoints or profiling.
Patches:
- Add 'cscopeignorecase' option. (Liang Wenzhi, 2006 Sept 3)
- Argument for feedkeys() to prepend to typeahead (Yakov Lerner, 2006 Oct
21)
- Load intl.dll too, not only libintl.dll. (Mike Williams, 2006 May 9, docs
patch May 10)
- Extra argument to strtrans() to translate special keys to their name (Eric
Arnold, 2006 May 22)
- 'threglookexp' option: only match with first word in thesaurus file.
(Jakson A. Aquino, 2006 Jun 14)
- Mac: indicate whether a buffer was modified. (Nicolas Weber, 2006 Jun 30)
- Allow negative 'nrwidth' for left aligning. (Nathan Laredo, 2006 Aug 16)
- ml_append_string(): efficiently append to an existing line. (Brad
Beveridge, 2006 Aug 26) Use in some situations, e.g., when pasting a
character at a time?
- gettabvar() and settabvar() functions. (Yegappan Lakshmanan, 2006 Sep 8)
- recognize hex numbers better. (Mark Manning, 2006 Sep 13)
等待补丁信息的更新:
9 Mac unicode patch (Da Woon Jung, Eckehard Berns):
8 Add patch from Muraoka Taro (Mar 16) to support input method on Mac?
New patch 2004 Jun 16
- selecting proportional font breaks display

- Command-key mappings do not work. (Alan Schmitt)
- With 'nopaste' pasting is wrong, with 'paste' Command-V doesn't work.
(Alan Schmitt)
- remove 'macatsui' option when this has been fixed.
- when 'macatsui' is off should we always convert to "macroman" and ignore
'termencoding'?

be used instead?
8 Win32: Add minidump generation. (George Reilly, 2006 Apr 24)

Add section in help files for these highlight groups?
8 "fg" and "bg" don't work in an xterm. Get default colors from xterm
with an ESC sequence.
xterm can send colors for many things. E.g. for the cursor:
<Esc>]12;?<Bel>
Can use this to get the background color and restore the colors on exit.
7 Add "DefaultFG" and "DefaultBG" for the colors of the menu. (Marcin
Dalecki has a patch for Motif and Carbon)

patches from Felbinger for a mathematica interface.
Or use emacs server kind of thing?
7 Add ":justify" command. Patch from Vit Stradal 2002 Nov 25.
- findmatch() should be adjusted for Lisp. See remark at

incomplete patch Mar 18)
- For GUI Find/Replace dialog support using a regexp. Patch for Motif
and GTK by degreneir (nov 10 and nov 18).
- Patch for "paranoid mode" by Kevin Collins, March 7. Needs much more work.
Vi 不兼容性:
- Try new POSIX tests, made after my comments. (Geoff Clare, 2005 April 7)
Version 1.5 is in ~/src/posix/1.5. (Lynne Canal)
8 With undo/redo only marks in the changed lines should be changed. Other
marks should be kept. Vi keeps each mark at the same text, even when it
is deleted or restored. (Webb)
Also: A mark is lost after: make change, undo, redo and undo.
Example: "{d''" then "u" then "d''": deletes an extra line, because the ''
position is one line down. (Veselinovic)
8 When stdin is not a tty, and Vim reads commands from it, an error should
make Vim exit.
7 Unix Vim (not gvim): Typing CTRL-C in Ex mode should finish the line
(currently you can continue typing, but it's truncated later anyway).
Requires a way to make CTRL-C interrupt select() when in cooked input.
8 When loading a file in the .exrc, Vi loads the argument anyway. Vim skips
loading the argument if there is a file already. When no file argument
given, Vi starts with an empty buffer, Vim keeps the loaded file. (Bearded)
6 In Insert mode, when using <BS> or <Del>, don't wipe out the text, but
only move back the cursor. Behaves like '$' in 'cpoptions'. Use a flag
in 'cpoptions' to switch this on/off.
8 When editing a file which is a symbolic link, and then opening another
symbolic link on the same file, Vim uses the name of the first one.
Adjust the file name in the buffer to the last one used? Use several file
names in one buffer???
Also: When first editing file "test", which is symlink to "test2", and
then editing "test2", you end up editing buffer "test" again. It's not
logical that the name that was first used sticks with the buffer.
7 The ":undo" command works differently in Ex mode. Edit a file, make some
changes, "Q", "undo" and _all_ changes are undone, like the ":visual"
command was one command.
On the other hand, an ":undo" command in an Ex script only undoes the last
change (e.g., use two :append commands, then :undo).
7 The ":map" command output overwrites the command. Perhaps it should keep
the ":map" when it's used without arguments?
7 CTRL-L is not the end of a section? It is for Posix! Make it an option.
7 Implement 'prompt' option. Init to off when stdin is not a tty.
7 CTRL-T in Insert mode inserts 'shiftwidth' of spaces at the cursor. Add a
flag in 'cpoptions' for this.
7 Add a way to send an email for a crashed edit session. Create a file when
making changes (containing name of the swap file), delete it when writing
the file. Supply a program that can check for crashed sessions (either
all, for a system startup, or for one user, for in a .login file).
7 Vi doesn't do autoindenting when input is not from a tty (in Ex mode).
7 "z3<CR>" should still use the whole window, but only redisplay 3 lines.
7 ":tag xx" should move the cursor to the first non-blank. Or should it go
to the match with the tag? Option?
7 Implement 'autoprint'/'ap' option.
7 Add flag in 'cpoptions' that makes <BS> after a count work like <Del>
(Sayre).
7 Add flag in 'cpoptions' that makes operator (yank, filter) not move the
cursor, at least when cancelled. (default Vi compatible).
7 This Vi-trick doesn't work: "Q" to go to Ex mode, then "g/pattern/visual".
In Vi you can edit in visual mode, and when doing "Q" you jump to the next
match. Nvi can do it too.
7 Support '\' for line continuation in Ex mode for these commands: (Luebking)
g/./a\ g/pattern1/ s/pattern2/rep1\\
line 1\ line 2\\
line 2\ line 3\\
. line4/
6 ":e /tmp/$tty" doesn't work. ":e $uid" does. Is $tty not set because of
the way the shell is started?
6 Vi compatibility (optional): make "ia<CR><ESC>10." do the same strange
thing. (only repeat insert for the first line).
GTK+ 1 (在 GTK 2 上没问题):
8 When using "gvim -geom 40x30" or setting 'columns' in .gvimrc or with a
GUIEnter autocommand, the width is still set to fit the toolbar. Also
happens when changing the font. How to avoid that the toolbar specifies
the minimal window width?
8 When using a theme with different scrollbars (gtkstep), the scrollbars can
be too narrow. (Drazen Kacar)
8 Font "7x14" has a bold version "7x14bold". Try to find the bold font by
appending "bold" when there are not 14 dashes.
GTK+ GUI 已知的漏洞:
9 Crash with X command server over ssh. (Ciaran McCreesh, 2006 Feb 6)
8 GTK 2: Combining UTF-8 characters not displayed properly in menus (Mikolaj
Machowski) They are displayed as separate characters. Problem in
creating a label?
8 GTK 2: Combining UTF-8 characters are sometimes not drawn properly.
Depends on the font size, "monospace 13" has the problem. Vim seems to do
everything right, must be a GTK bug. Is there a way to work around it?
9 Can't paste a Visual selection from GTK-gvim to vim in xterm or Motif gvim
when it is longer than 4000 characters. Works OK from gvim to gvim and
vim to vim. Pasting through xterm (using the shift key) also works.
It starts working after GTK gvim loses the selection and gains it again.
- Gnome2: When moving the toolbar out of the dock, so that it becomes
floating, it can no longer be moved. Therefore making it float has been
blocked for now.
Win32 GUI 已知的漏洞:
- Win32: tearoff menu window should have a scrollbar when it's taller than
the screen.
8 non-ASCII font names don't work. Need to convert from 'encoding' and use
the wide functions.
8 On Windows 98 the unicows library is needed to support functions with UCS2
file names. Can we load unicows.dll dynamically?
8 When the primary monitor is below or right of the secondary monitor and
Vim is on the secondary monitor it will often move to the primary monitor.
Window position coordinates can be negative. (James Harvey)
8 The -P argument doesn't work very well with many MDI applications.
The last argument of CreateWindowEx() should be used, see MSDN docs.
Tutorial: http://win32assembly.online.fr/tut32.html
8 In eval.c, io.h is included when MSWIN32 is defined. Shouldn't this be
WIN32? Or can including io.h be moved to vim.h? (Dan Sharp)
7 Windows XP: When using "ClearType" for text smoothing, a column of yellow
pixels remains when typing spaces in front of a "D" ('guifont' set to
"lucida_console:h8").
6 Win32 GUI: With "-u NONE -U NONE" and doing "CTRL-W v" "CTRL-W o", the ":"
of ":only" is highlighted like the cursor. (Lipelis)
8 When 'encoding' is "utf-8", should use 'guifont' for both normal and wide
characters to make Asian languages work. Win32 fonts contain both
type of characters.
7 When font smoothing is enabled, redrawing can become very slow. The reason
appears to be drawing with a transparent background. Would it be possible
to use an opaque background in most places?
8 Use another default for 'termencoding': the active codepage. Means that
when 'encoding' is changed typing characters still works properly.
Alternative: use the Unicode functions to obtain typed characters.
8 Win32: Multi-byte characters are not displayed, even though the same font
in Notepad can display them. (Srinath Avadhanula) Try with the
UTF-8-demo.txt page with Andale Mono.
7 The cursor color indicating IME mode doesn't work properly. (Shizhu Pan,
2004 May 9)
8 Win32: When clicking on the gvim title bar, which gives it focus, produces
a file-changed dialog, after clicking on a button in that dialog the gvim
window follows the mouse. The button-up event is lost. Only with
MS-Windows 98?
Try this: ":set sw ts", get enter-prompt, then change the file in a
console, go back to Vim and click "reload" in the dialog for the changed
file: Window moves with the cursor!
Put focus event in input buffer and let generic Vim code handle it?
8 When activating the Vim window with mouse click, don't move cursor to
mouse position. Catch WM_MOUSEACTIVATE. (Luevelsmeyer)
8 Win32: When mouse is hidden and in the toolbar, moving it won't make it
appear. (Sami Salonen)
8 Win32 GUI: With maximized window, ":set go-=r" doesn't use the space that
comes available. (Poucet) It works OK on Win 98 but doesn't work on Win
NT 4.0. Leaves a grey area where the scrollbar was. ":set go+=r" also
doesn't work properly.
8 When Vim is minimized and when maximizing it a file-changed dialog pops
up, Vim isn't maximized. It should be done before the dialog, so that it
appears in the right position. (Webb)
9 When selecting at the more-prompt or hit-enter-prompt, the right mouse
button doesn't give popup menu.
At the hit-enter prompt CTRL-Y doesn't work to copy the modeless
selection.
On the command line, don't get a popup menu for the right mouse button.
Let the middle button paste selected text (not the clipboard but the
non-Visual selection)? Otherwise CTRL-Y has to be used to copy the text.
8 When 'grepprg' doesn't execute, the error only flashes by, the
user can hardly see what is wrong. (Moore)
Could use vimrun with an "-nowait" argument to only wait when an error
occurs, but "command.com" doesn't return an error code.
8 When the 'shell' cannot be executed, should give an appropriate error msg.
Esp. for a filter command, currently it only complains the file could not
be read.
7 Add an option to add one pixel column to the character width? Lucida
Console italic is wider than the normal font ("d" overlaps with next char).
Opposite of 'linespace': 'columnspace'.
7 At the hit-enter prompt scrolling now no longer works. Need to use the
keyboard to get around this. Pretend <CR> was hit when the user tries to
scroll?
7 Scrollbar width doesn't change when selecting other windows appearance.
Also background color of Toolbar and rectangle below vert. scrollbar.
7 "!start /min cmd" should run in a minimized window, instead of using
"/min" as the command name. (Rogall)
6 Drawing text transparently doesn't seem to work (when drawing part cursor).
8 CTRL key doesn't always work in combination with ALT key. It does work
for function keys, not for alphabetic characters. Perhaps this is because
CTRL-ALT is used by Windows as AltGr?
8 CTRL-- doesn't work for AZERTY, because it's CTRL-[ for QWERTY. How do we
know which keyboard is being used?
7 When scrolling, and a background color is dithered, the dither pattern
doesn't always join correctly between the scrolled area and the new drawn
area (Koloseike).
8 When gui_init_font() is called with "*", p_guifont is freed while it might
still be used somewhere. This is too tricky, do the font selection first,
then set the new font by name (requires putting all logfont parameters in
the font name).
Athena 和 Motif:
6 New Motif toolbar button from Marcin Dalecki:
- When the mouse pointer is over an Agide button the red becomes black.
Something with the way colors are specified in the .xpm file.
- The pixmap is two pixels smaller than it should be. The gap is filled
with grey instead of the current toolbar background color.
9 Can configure be changed to disable netbeans if the Xpm library is
required and it's missing?
8 When using the resource "Vim*borderwidth 2" the widgets are positioned
wrong.
9 XIM is disabled by default for SGI/IRIX. Fix XIM so that 'imdisable' can
be off by default.
9 XIM doesn't work properly for Athena/Motif. (Yasuhiro Matsumoto) For now,
keep XIM active at all times when the input method has the preediting
flag.
8 X11: A menu that contains an umlaut is truncated at that character.
Happens when the locale is "C", which uses ASCII instead of IS0-8859-1.
Is there a way to use latin1 by default? Gnome_init() seems to do this.
8 Perhaps use fontsets for everything?
6 When starting in English and switching the language to Japanese, setting
the locale with ":lang", 'guifontset' and "hi menu font=", deleting all
menus and setting them again, the menus don't use the new font. Most of
the tooltips work though...
7 Motif: when using a file selection dialog, the specified file name is not
always used (when specifying a filter or another directory).
8 When 'encoding' is different from the current locale (e.g., utf-8) the
menu strings don't work. Requires conversion from 'encoding' to the
current locale. Workaround: set 'langmenu'.
Athena GUI:
9 When dragging the scrollbar thumb very fast, focus is only obtained in
the scrollbar itself. And the thumb is no longer updated when moving
through files.
7 The file selector is not resizable. With a big font it is difficult to
read long file names. (Schroeder)
4 Re-write the widget attachments and code so that we will not have to go
through and calculate the absolute position of every widget every time the
window is refreshed/changes size. This will help the "flashing-widgets"
problem during a refresh.
5 When starting gvim with all the default colors and then typing
":hi Menu guibg=cyan", the menus change color but the background of the
pullright pixmap doesn't change colors.
If you type ":hi Menu guibg=cyan font=anyfont", then the pixmap changes
colors as it should.
Allocating a new pixmap and setting the resource doesn't change the
pullright pixmap's colors. Why? Possible Athena bug?
Motif GUI:
- gui_mch_browsedir() is missing.
7 Use XmStringCreateLocalized() instead of XmStringCreateSimple()?
David Harrison says it's OK (it exists in Motif 1.2).
8 Lesstif: When deleting a menu that's torn off, the torn off menu becomes
very small instead of disappearing. When closing it, Vim crashes.
(Phillipps)
GUI:
9 On Solaris, creating the popup menu causes the right mouse button no
longer to work for extending the selection. (Halevy)
9 When running an external program, it can't always be killed with CTRL-C.
e.g., on Solaris 5.5, when using "K" (Keech). Other 'guipty' problems on
Solaris 2.6. (Marley)
9 On Solaris: Using a "-geometry" argument, bigger than the window where Vim
is started from, causes empty lines below the cmdline. (raf)
8 X11 GUI: When menu is disabled by excluding 'm' from 'guioptions', ALT key
should not be used to trigger a menu (like the Win32 version).
8 When setting 'langmenu', it should be effective immediately. Store both
the English and the translated text in the menu structure. Re-generate
the translation when 'langmenu' has changed.
8 Basic flaw in the GUI code: NextScreen is updated before calling
gui_write(), but the GUI code relies on NextScreen to represent the state
of where it is processing the output.
Need better separation of Vim core and GUI code.
8 When fontset support is enabled, setting 'guifont' to a single font
doesn't work.
8 Menu priority for sub-menus for: Amiga, BeOS.
8 When translating menus ignore the part after the Tab, the shortcut. So
that the same menu item with a different shortcut (e.g., for the Mac) are
still translated.
8 Add menu separators for Amiga, RISCOS.
8 Add way to specify the file filter for the browse dialog. At least for
browse().
8 Add dialog for search/replace to other GUIs? Tk has something for this,
use that code? Or use console dialog.
8 When selecting a font with the font dialog and the font is invalid, the
error message disappears too quick.
7 More features in the find/replace dialog:
- regexp on/off
- search in selection/buffer/all buffers/directory
when all buffers/directory is used:
- filter for file name
when directory is used:
- subdirectory on/off
- top directory browser
8 gui_check_colors() is not called at the right moment. Do it much later,
to avoid problems.
8 gui_update_cursor() is called for a cursor shape change, even when there
are mappings to be processed. Only do something when going to wait for
input. Or maybe every 100 ms?
8 X11: When the window size is reduced to fit on screen, there are blank
lines below the text and bottom scrollbar. "gvim -geometry 80x78+0+0".
When the "+0+0" is omitted it works.
8 When starting an external command, and 'guipty' set, BS and DEL are mixed
up. Set erase character somehow?
8 A dead circumflex followed by a space should give the '^' character
(Rommel). Look how xterm does this.
Also: Bednar has some code for dead key handling.
Also: Nedit 5.0.2 with USE_XMIM does it right. (Gaya)
8 The compose key doesn't work properly (Cepas). Both for Win32 and X11.
7 The cursor in an inactive window should be hollow. Currently it's not
visible.
7 GUI on Solaris 2.5.1, using /usr/dt/..: When gvim starts, cursor is
hollow, after window lowered/raised it's OK. (Godfrey)
7 When starting GUI with ":gui", and window is made smaller because it
doesn't fit on the screen, there is an extra redraw.
8 When setting font with .Xdefaults, there is an extra empty line at the
bottom, which disappears when using ":set guifont=<Tab>". (Chadzelek)
8 When font shape changes, but not the size, doing ":set font=" does not
redraw the screen with the new font. Also for Win32.
When the size changes, on Solaris 2.5 there isn't a redraw for the
remaining part of the window (Phillipps).
- Flashes really badly in certain cases when running remotely from a Sun.
4 Re-write the code so that the highlighting isn't changed multiple times
when doing a ":hi clear". The color changes happen three or more times
currently. This is very obvious on a 66Mhz 486.
MSDOS/DJGPP:
9 Pressing CTRL-C often crashes the console Vim runs in. (Ken Liao)
When 'bioskey' isn't set it doesn't happen. Could be a problem with the
BIOS emulation of the console. Version 5.6 already had this problem.
8 DJGPP: "cd c:" can take us to a directory that no longer exists.
change_drive() doesn't check this. How to check for this error?
9 The 16 bit version runs out of memory very quickly. Should find unused
code and reduce static data. Resetting 'writebackup' helps to be able to
write a file.
9 Crash when running on Windows 98 in a console window and pressing CTRL-C.
Happens now and then. When debugging Vim in gdb this also happens. Since
the console crashes, might be a bug in the DOS console. Resetting
'bioskey' avoids it, but then CTRL-C doesn't work.
9 DOS: Make CTRL-Fx and ALT-Fx work.
CTRL-F1 = CE-5E, CTRL-F2 = CE-5F, .., CTRL-F10 = CE-67
ALT-F1 = CE-68, ALT-F2 = CE-69, .., ALT-F10 = CE-71
Shifted cursor keys produce same codes as unshifted keys. Use bioskey(2)
to get modifier mask for <S-C-M-Fx>.
Use K_SPECIAL/KS_MODIFIER codes to insert modifier mask in input stream?
Make this work like in Win32 console.
Mapping things like <M-A> doesn't work, because it generates an extended
key code. Use a translation table?
9 Can't read an opened swap file when the "share" command has not been used.
At least ignore the swap files that Vim has opened itself.
8 Use DJGPP 2.03.
8 The Dos32 version (DJGPP) can't use long file names on Windows NT.
Check if new package can be used (v2misc/ntlfn08[bs].zip).
8 setlocale() is bogus.
8 Vim busy waits for new characters or mouse clicks. Should put in some
sort of sleep, to avoid eating 50% of the CPU time. Test on an unpatched
Windows 95 system!
8 DJGPP: when shell is bash, make fails. (Donahoe)
7 Hitting CTRL-P twice quickly (e.g., in keyword completion) on a 8088
machine, starts printer echo! (John Mullin).
7 MSDOS 16 bit version can't work with COMSPEC that has an argument, e.g.:
COMSPEC=C:\WINDOWS\COMMAND.COM /E:4096 (Bradley)
Caused by BCC system() function (Borland "make" has the same problem).
8 Mouse: handle left&right button pressed as middle button pressed. Add
modifier keys shift, ctrl and alt.
7 When too many files are open (depends on FILES), strange things happen.
The Dos16 version runs out of memory, in the Dos32 version "!ls" causes a
crash. Another symptom: .swp files are not deleted, existing files are
"[New file]".
7 DJGPP version doesn't work with graphics display mode. Switch to a mode
that is supported?
8 DJGPP: ":mode" doesn't work for many modes. Disable them.
8 DJGPP: When starting in Ex mode, shouldn't clear the screen. (Walter
Briscoe)
MSDOS、OS/2 和 Win32:
8 OS/2: Add backtick expansion. Undefine NO_EXPANDPATH and use
gen_expand_wildcards().
8 OS/2: Add clipboard support? See example clipbrd.exe from Alexander
Wagner.
8 OS/2: Add Extended Attributes support and define HAVE_ACL.
8 OS/2: When editing a file name "foo.txt" that is actually called FOO.txt,
writing uses "foo.txt". Should obtain the real file name.
8 Should $USERPROFILE be preferred above $HOMEDRIVE/$HOMEPATH? No, but it's
a good fallback, thus use:
$HOME
$HOMEDRIVE$HOMEPATH
SHGetSpecialFolderPath(NULL, lpzsPath, CSIDL_APPDATA, FALSE);
$USERPROFILE
SHGetSpecialFolderPath(NULL, lpzsPath, CSIDL_COMMON_APPDATA, FALSE);
$ALLUSERSPROFILE
$SYSTEMDRIVE\
C:\
8 Win32 console: <M-Up> and <M-Down> don't work. (Geddes) We don't have
special keys for these. Should use modifier + key.
8 Win32 console: caps-lock makes non-alpha keys work like with shift.
Should work like in the GUI version.
8 Environment variables in DOS are not case sensitive. Make a define for
STRCMP_ENV(), and use it when comparing environment var names.
8 Setting 'shellslash' has no immediate effect. Change all file names when
it is set/reset? Or only use it when actually executing a shell command?
8 When editing a file on a Samba server, case might matter. ":e file"
followed by ":e FILE" will edit "file" again, even though "FILE" might be
another one. Set last used name in buflist_new()? Fix do_ecmd(), etc.
8 When a buffer is editing a file like "ftp://mach/file", which is not going
to be used like a normal file name, don't change the slashes to
backslashes. (Ronald Hoellwarth)
Windows 95:
8 Editing a file by it's short file name and writing it, makes the long file
name disappear. Setting 'backupcopy' helps.
Use FindFirstFile()->cAlternateFileName in fname_case() (George Reilly).
8 Doing wildcard expansion, will match the short filename, but result in the
long filename (both DJGPP and Win32).
Win32 控制台:
9 When editing a file by its short file name, it should be expanded into its
long file name, to avoid problems like these: (Mccollister)
1) Create a file called ".bashrc" using some other editor.
2) Drag that file onto a shortcut or the actual executable.
3) Note that the file name is something like BASHRC~1
4) Go to File->Save As menu item and type ".bashrc" as the file name.
5) Press "Yes" to indicate that I want to overwrite the file.
6) Note that the message "File exists (add ! to override)" is displayed
and the file is not saved.
Use FindFirstFile() to expand a file name and directory in the path to its
long name.
8 Also implement 'conskey' option for the Win32 console version? Look at
how Xvi does console I/O under Windows NT.
7 Re-install the use of $TERM and support the use of different terminals,
besides the console.
8 Use of <altgr> modifier doesn't work? 5.3 was OK. (Garcia-Suarez/Guckes)
9 Mapping <C-S-Tab> doesn't work correctly. How to see the difference with
<C-S-i>?
9 tmpnam() uses file in root of file system: "\asdf". That doesn't work on
a Netware network drive. Use same function as for Win32 GUI?
8 In os_win32.h, HAVE_STRICMP and HAVE_STRNICMP are defined only if __GNUC__
is not defined. Shouldn't that be the other way around?
7 Use SetConsoleCP() and SetConsoleOutputCP() to implement 'termencoding'?
Avoids that input and output work differently. Need to be restored when
exiting.
Amiga:
8 In mch_inchar() should use convert_input_safe() to handle incomplete byte
sequences.
9 In mch_expandpath() a "*" is to be expanded, but "\*" isn't. Remove
backslashes in result.
8 Executing a shell, only one option for 'shell' is separated. Should do
all options, using white space separation.
Macintosh:
- GUI: gui_mch_browsedir() is missing.
7 Patch to add 'transparency' option. Disadvantage: it's slow. (Eckehard
Berns, 2004 May 9) http://ecki.to/vim/TransBack-2004-05-09.diff
Needs more work. Add when someone really wants it.
7 Loading the Perl library only works on OS/X 10.2 or 10.3, never on both.
Load the Perl library dynamically see Python sources file dynload_mac
(Jack)
dynamic linking: http://developer.apple.com/technotes/tn2002/tn2064.html
8 Inputting Unicode characters does not work in the terminal. They appear
to arrive as upper and lower bytes. (David Brown, 2004 April 17)
8 Typing Unicode characters doesn't work at all in the GUI.
8 inputdialog() doesn't resize when giving more text lines. (David Fishburn,
2006 Sept 28)
9 Problems in Carbon version for OS X: (Benji Fisher)
- keyboard shortcuts in the menus get lost.
8 The Vim/About menu doesn't work.
8 ":gui" doesn't fork. Enabling the code in gui.c to fork causes a SEGV.
8 Define vim_mkdir() for Macintosh.
8 Define mch_writable() for Macintosh.
8 Some file systems are case-sensitive, some are not. Turn
CASE_INSENSITIVE_FILENAME into an option, at least for completion.
9 When DiskLock is running, using a swap file causes a crash. Appears to be
a problem with writing a file that starts with a dot. (Giacalone)
9 On G3 Mac, OS version 8, control strip causes characters messed up when
scrolling (CTRL-L cleans it up). (Benji Fisher)
9 On G3 Mac, OS version 8, variable-speed scrolling doesn't work, after two
seconds of scrolling the screen freezes. (Benji Fisher)
9 In mac_expandpath() check that handling of backslashes is done properly.
8 Standard Mac shortcuts are missing. (Amerige)
8 Handling of non-fixed width fonts is wrong. (Amerige)
"小" 问题:
- When using e_secure in do_one_cmd() mention the command being executed,
otherwise it's not clear where it comes from.
8 When disabling FEAT_CMDL_COMPL compilation fails. Would need to avoid
using parse_compl_arg() in eval.c and uc_scan_attr().
9 For Turkish vim_tolower() and vim_toupper() also need to use utf_
functions for characters below 0x80. (Sertacyildiz)
9 When the last edited file is a help file, using '0 in a new Vim doesn't
edit the file as a help file.
8 When an ":edit" is inside a try command and the ATTENTION prompt is used,
the :catch commands are always executed, also when the file is edited
normally. Should reset did_emsg and undo side effects. Also make sure
the ATTENTION message shows up. Servatius Brandt works on this.
9 When using ":e ++enc=foo file" and the file is already loaded with
'fileencoding' set to "bar", then do_ecmd() uses that buffer, even though
the fileencoding differs. Reload the buffer in this situation? Need to
check for the buffer to be unmodified.
8 ":g//" gives "Pattern not found error" with E486. Should not use the
error number, it's not a regular error message.
7 Vimtutor leaves escape sequence in terminal. This is the xterm response to
requesting the version number. (Yasuhiro Matsumoto)
8 When redirecting and using ":silent" the current column for displaying and
redirection can be different. Use a separate variable to hold the column
for redirection.
7 The messages for "vim --help" and "vim --version" don't use
'termencoding'.
- Could the hit-enter prompt be avoided when a message only overlaps the
'showcmd' area? Clear that area when the next cmd is typed.
8 When 'scrollbind' is set, a window won't scroll horizontally if the cursor
line is too short. Add a word in 'scrollopt' to allow moving the cursor
to longer line that is visible. A similar thing is done for the GUI when
using the horizontal scrollbar.
7 VisVim can only open one file. Hard to solve: each opened file is passed
with a separate invocation, would need to use timestamps to know the
invocations belong together.
8 When giving a ":bwipeout" command a file-changed dialog may popup for this
buffer, which is pointless. (Mike Williams)
8 On MS-Windows ":make" doesn't show output while it is working. Use the
tee.exe from http://unxutils.sourceforge.net/ ? About 16 Kbyte in the
UnxUtils.zip archive.
Alternate one: http://www.pramodx.20m.com/tee_for_win32.htm, but Walter
Briscoe says it's not as good.
8 "stl" and "stlnc" in 'fillchars' don't work for multi-byte characters.
8 When doing Insert mode completion a mapping cannot recursively call
edit(), because the completion information is global. Put everything in
an allocated structure?
6 Python: ":py raw_input('prompt')" doesn't work. (Manu Hack)
8 Command line completion: buffers "foo.txt" and "../b/foo.txt", completing
":buf foo<Tab>" doesn't find the second one. (George V. Reilly)
7 Output for ":scriptnames" and ":breaklist" should shorten the file names:
use "~/" when possible.
7 mb_off2cells() doesn't work correctly on the tail byte of a double-byte
character. (Yasuhiro Matsumoto) It should return 1 when used on a tail
byte, like for utf-8. Store second byte of double-byte in ScreenLines2[]
(like for DBCS_JPNU) and put a zero in the second byte (like for UTF-8).
8 'backupdir' and 'directory' should use $TMPDIR, $TMP and/or $TEMP when
defined.
7 Inside a function with "perl <<EOF" a line with "$i++" is recognized as an
":insert" command, causing the following "endfunction" not to be found.
Add skipping this perl construction inside function definitions.
7 When 'ttimeoutlen' is 10 and 'timeoutlen' is 1000, there is a keycode
"<Esc>a" and a mapping <Esc>x", when typing "<Esc>a" with half a second
delay should not be interpreted as a keycode. (Hans Ginzel)
7 ":botright 1 new" twice causes all window heights to be changed. Make the
bottom window only bigger as much as needed.
7 "[p" doesn't work in Visual mode. (David Brown)
7 The Cygwin and MingW makefiles define "PC", but it's not used anywhere.
Remove? (Dan Sharp)
9 User commands use the context of the script they were defined in. This
causes a "s:var" argument to unexpectedly use a variable in the defining
script, not the calling script. Add an argument to ":command":
"-keepcontext". Do replace <SID>, so that a function in the defining
script can be called.
8 The Japanese message translations for MS-Windows are called ja.sjis.po,
but they use encoding cp932. Rename the file and check that it still
works.
9 When a syntax region does not use "keepend" and a contained item does use
"extend", this makes the outer region stop at the end of the contained
region. (Lutz Eymers) Another example Nov 14 2002.
8 A very long message in confirm() can't be quit. Make this possible with
CTRL-C.
7 clip_x11_own_selection() uses CurrentTime, that is not allowed. VNC X
server has a problem with this. (Mark Waggoner) Remembering the timestamp
of events isn't always possible. We don't get them in an xterm. GTK
doesn't obtain the selection again when the timestamp differs, thus it
won't work for GTK anyway.
8 When the clipboard isn't supported: ":yank*" gives a confusing error
message. Specifically mention that the register name is invalid.
8 "gf" always excludes trailing punctuation characters. file_name_in_line()
is currently fixed to use ".,:;!". Add an option to make this
configurable?
8 'hkmap' should probably be global-local.
9 When "$" is in 'cpoptions' and folding is active, a "C" command changes
the folds and resets w_lines_valid. The display updating doesn't work
then. (Pritesh Mistry)
8 ":s!from!to!" works, but ":smagic!from!to!" doesn't. It sees the "!" as a
flag to to the command. Same for ":snomagic". (Johan Spetz)
8 Using ":s" in a function changes the previous replacement string. Save
"old_sub" in save_search_patterns()?
8 Should allow multi-byte characters for the delimiter: ":s+a+b+" where "+"
is a multi-byte character.
8 When appending to a file and 'patchmode' isn't empty, a backup file is
always written, even when the original file already exists.
7 When using "daw" on the last word in a file and this is a single letter,
nothing is deleted. Should delete the letter and preceding white space.
9 When getting focus while writing a large file, could warn for this file
being changed outside of Vim. Avoid checking this while the file is being
written.
9 The "Error detected while processing modelines" message should have an
error number.
7 The message in bt_dontwrite_msg() could be clearer.
8 The script ID that is stored with an option and displayed with ":verbose
set" isn't reset when the option is set internally. For example when
'foldlevel' is set from 'foldlevelstart'.
8 Also store the line number with the script ID and use it for ":verbose",
so that "set nocompatible" is found when it changes other option values.
When an option is set indirectly mention the command? E.g. when
":diffsplit" sets 'foldmethod'.
8 In the fileformat dialog, "Cancel" isn't translated. Add a global
variable for this. (Eduardo Fernandez)
9 When editing a file with 'readonly' set, there is no check for an existing
swap file. Then using ":write" (without making any changes) doesn't give
a warning either. Should check for an existing swap file without creating
one.
7 When 'showbreak' is set, the amount of space a Tab occupies changes.
Should work like 'showbreak' is inserted without changing the Tabs.
7 When 'mousefocus' is set and switching to another window with a typed
command, the mouse pointer may be moved to a part of the window that's
covered by another window and we lose focus. Only move in the y
direction, not horizontally?
8 When using CTRL-D after ":help", restrict the number of matches to a
thousand, otherwise using CTRL-D without an argument takes too long.
8 ":hardcopy":
- Using the cterm_color[] table is wrong when t_colors is > 16.
- Need to handle unprintable characters.
- Win32: On a B&W printer syntax highlighting isn't visible. Perform
dithering to make grey text?
- Add a flag in 'printoptions' to add an empty page to make the total
number even. "addempty"? (Mike Williams)
- Respect 'linebreak'. Perhaps also 'showbreak'?
- Should interpreted CTRL-L as a page break.
- Grey line numbers are not always readable. Add field in 'printoptions'.
Default to black when no syntax highlighting.
- Be able to print a window in diff mode.
- Be able to specify a colorscheme to use for printing. And a separate
one for B&W printing (if that can be detected).
8 In Visual block mode with 'lbr' set, a change command doesn't insert the
text in following lines where the linebreak changes.
9 dosinst.c: The DJGPP version can't uninstall the Uninstall registry key on
Windows NT. How to install a .inf file on Windows NT and how to detect
that Windows NT is being used?
8 When 'virtualedit' is "block,insert" and encoding is "utf-8", selecting a
block of one double-wide character, then "d" deletes only half of it.
8 When 'virtualedit' is set, should "I" in blockwise visual mode also insert
in lines that don't extend into the block?
8 With 'virtualedit' set, in Insert mode just after the end of line, CTRL-O
yh does not yank the last character of the line. (Pavel Papushev)
Doing "hl" first appears to make it work.
8 With 'virtualedit' set it's possible to move into the blank area from
'linebreak'.
8 With 'virtualedit' set and 'selection' "exclusive", a Visual selection
that ends in or after a tab, "d" doesn't delete (part of) the tab.
(Helmut Stiegler)
8 With 'virtualedit' set, a blockwise Visual selection that starts and ends
in a tab, "<" shifts too much. (Helmut Stiegler)
9 When jumping to a tag, the search pattern is put in the history. When
'magic' is on, the pattern may not work. Translate the pattern depending
on p_magic when putting it in the history? Alternative: Store value of
'magic' in history. (Margo)
9 optwin.vim: Restoring a mapping for <Space> or <CR> is not correct for
":noremap". Add "mapcmd({string}, {mode})? Use code from ":mkexrc".
9 incsearch is incorrect for "/that/<Return>/this/;//" (last search pattern
isn't updated).
9 term_console is used before it is set (msdos, Amiga).
9 Get out-of-memory for ":g/^/,$s//@/" on 1000 lines, this is not handled
correctly. Get many error messages while redrawing the screen, which
cause another redraw, etc.
8 [<C-I> doesn't work when '*' is in 'iskeyword'. find_pattern_in_path()
must escape special characters in the pattern.
8 Vim can overwrite a read-only file with ":w!". ":w" can't overwrite an
existing file, "w!" can, but perhaps not a read-only file? Then use
":w!!" for that.
Or ask for permission to overwrite it (if file can be made writable) and
restore file to readonly afterwards.
Overwriting a file for which a swap file exists is similar issue.
7 When compiled with "xterm_clipboard", startup can be slower and might get
error message for invalid $DISPLAY. Try connecting to the X server in the
background (forked), so that Vim starts up quicker? Connect as soon as
the clipboard is to be used (Visual select mode starts, paste from
clipboard)
7 X11: Some people prefer to use CLIPBOARD instead of PRIMARY for the normal
selection. Add an "xclipboard" argument to the 'clipboard' option? (Mark
Waggoner)
8 For xterm need to open a connection to the X server to get the window
title, which can be slow. Can also get the title with "<Esc>[21t", no
need to use X11 calls. This returns "<Esc>]l{title}<Esc>\".
6 When the xterm reports the number of colors, a redraw occurs. This is
annoying on a slow connection. Wait for the xterm to report the number of
colors before drawing the screen. With a timeout.
8 When the builtin xterm termcap contains codes that are not wanted, need a
way to avoid using the builtin termcap.
8 Xterm sends ^[[H for <Home> and ^[[F for <End> in some mode. Also
recognize these keys? Mostly useful for xterm simulators, like gnometerm.
See http://dickey.his.com/xterm/xterm.faq.html#xterm_pc_style.
8 For xterm also recognize keypad up/down/left/right and insert.
8 '[ and '] should be set to start/end of line when using a linewise operator
(e.g., ":w").
8 CTRL-A can't handle big "long" numbers, they become negative. Check for
"-" character, if not present, use unsigned long.
8 Make it possible to disable the special meaning of "#" in the first column
for ">>".
8 Add suspending with CTRL-Z at the "more" prompt, and when executing a long
script in do_cmdline().
8 When using 'hidden', many swap files will be open. When Vim runs into the
maximum number of open files, error messages will appear. Detect that
this problem is present, and close any hidden files that don't have
changes.
8 With 'viminfo' set such that the ".viminfo" file is written on a FAT
filesystem, an illegal file name may be created: ".vim".
8 For each buffer that is opened, the viminfo file is opened and read to
check for file marks. This can be slow.
7 In xterm, recognize both vt100 and vt220 cursor keys. Change
add_termcode() to not remove an existing entry for a name, when it's
needed.
Need a generic solution to recognize different codes for the same key.
8 Core dump within signal function: gdb doesn't show stack backtrace! Option
to skip catch_signals()?
9 Repeating a "cw" with "." doesn't work if the text was pasted from the
clipboard. (Thomas Jones) It's because the menu/toolbar item exits Insert
mode and uses "gP". How to fix this without breaking inserting a block of
text?
8 In Replace mode pasting from the clipboard (using menu or toolbar) inserts
all the text. Add ":rmenu"?
8 Pasting with the mouse in Replace mode inserts the text, instead of
overwriting, when it is more than one line. Same for using <C-R>.
9 CTRL-E and CTRL-Y don't work in small window when 'so' is 4 and lines are
wrapping (Acevedo/in.226). E.g., when using CTRL-E, window height 7,
window might actually scroll down when last line of buffer is displayed.
--> Remember if the previous command was "cursor follows screen" or
"screen follow cursor" and use this in cursupdate().
7 tilde_replace() can only handle "~/", should also do "~user/".
Get the list of home directories (from /etc/passwd? Use getpwent()) and
use some clever algorithm to match a path with that. Find common strings
in the list?
8 When dragging status line with mouse, sometimes a jump when first clicking
on the status line (caused by 'winheight'). Select window on button up,
instead of on button down.
8 Dragging the status line doesn't scroll but redraw.
9 Evaluating 'statusline' in build_stl_str_hl() does not properly check for
reaching the end of the available buffer.
Patch to dynamically allocate the buffer for % items. (Eric Arnold, 2006
May 14)
8 When performing incremental search, should abort searching as soon as a
character is typed.
8 When the value of $MAKE contains a path, configure can't handle this.
It's an autoconf bug. Remove the path from $MAKE to work around it.
8 How to set VIMRC_FILE to \"something\" for configure? Why does this not
work: CFLAGS='-DVIMRC_FILE=\"/mydir/myfile\"' ./configure
8 The temporary file is sometimes not writable. Check for this, and use an
alternate name when it isn't. Or add the 'temptemplate' option: template
for the temp file name ":set temptemplate=/usr/tmp/?????.tmp".
Also: Win32 version uses Windows temp directory, which might not work for
cygwin bash.
7 Get error "*, \+ or \( operand could be empty" for pattern "\(.\)\1\{3}".
Remember flags for backreferences.
7 When switching to Daylight Saving Time, Vim complains that a file has been
changed since last read. Can we use a function that uses GMT?
7 When completing an environment variable after a '$', check for file names
that contain a '$' after all have been found.
8 When "cm" termcap entry is missing, starting gvim shouldn't complain about
it. (Lohner) Try out with "vt100" entry, cm replaced with cX.
7 When an include file starts with "../", the check for already visiting
this file doesn't work. Need to simplify the file name.
7 The names and comments for the arguments of do_browse() are confusing.
"dflt" isn't the default file name when "initdir" is not NULL and
"initdir" is the default path to be used.
7 When 'scrolloff' is exactly half the window height, "j" causes a scroll of
two lines at a time. "k" doesn't do this. (Cory T. Echols)
8 When write_viminfo() is used while there are many orphaned viminfo
tempfiles writing the viminfo file fails. Give a clear error message so
that the user knows he has to delete the files.
7 It's possible to redefine a script-local function with ":func
<SNR>123_Test()". (Krishna) Disallow this.
我无法重现这些 (如果你可以，请告知！):
9 NT 4.0 on NTFS file system: Editing ".bashrc" (drag and drop), file
disappears. Editing ".xyz" is OK. Also, drag&drop only works for three
files. (McCollister)
(可能) 不会解决的问题:
- GTK: when using the popup menu with spelling suggestions and releasing the
right mouse button before the menu appears selecting an item with the
right mouse button has no effect. GTK does not produce an event for this.
- xterm title: The following scenario may occur (esp. when running the Vim
test script): Vim 1 sets the title to "file1", then restores the title to
"xterm" with an ESC sequence when exiting. Vim 2 obtains the old title
with an X library call, this may result in "file1", because the window
manager hasn't processed the "xterm" title yet. Can apparently only be
worked around with a delay.
- In a terminal with 'mouse' set such that the mouse is active when entering
a command line, after executing a shell command that scrolls up the
display and then pressing ":": Selecting text with the mouse works like
the display wasn't scrolled. Vim doesn't know how much the external
command scrolled up the display. Use Shift to select text.
- X windows: When $DISPLAY points to a X server where there is no access
permission, trying to connect to the X server causes an error message.
XtOpenDisplay() prints this directly, there is no way to avoid it.
- X windows: Setting 'guifontset' to an illegal value sometimes crashes Vim.
This is caused by a fault in a X library function, can't be solved in Vim.
- Win32 tcl: has("tcl") hangs when the tcl84.dll is from cygwin.
- Motif: When adding a menu item "Find this &Symbol", the "s" in "this" will
be underlined, instead of in "Symbol". Motif doesn't let us specify which
character gets the highlighting.
- Moving the cursor removes color in color-xterm. This is a color-xterm
problem! color-xterm ver. 6.1 beta 3 and later work properly.
- In zsh, "gvim&" changes the terminal settings. This is a zsh problem.
(Jennings)
- Problem with HPterm under X: old contents of window is lost (Cosentino).
- Amiga: When using quickfix with the Manx compiler we only get the first 25
errors. How do we get the rest?
- Amiga: The ":cq" command does not always abort the Manx compiler. Why?
- Linux: A file with protection r--rw-rw- is seen readonly for others. The
access() function in GNU libc is probably wrong.
- MSDOS: When using smartdrive with write-back buffering, writing to a
readonly floppy will cause problems. How to test for a writable floppy
first?
- MSDOS: Both 16 and 32 bit versions: File name expansion doesn't work for
names that start with a dot. These used to be illegal file names.
- When doing a CTRL-Z and typing a command for the shell, while Vim is busy
(e.g. writing a file), the command for the shell is sometimes eaten by Vim,
because the terminal mode is changed from RAW to CBREAK.
- An old version of GNU tgoto can't handle the terminfo code for "AF". The
"%p1" is interpreted as "%p" and "1", causing color not to be working.
Fix: Change the "%p1" in the "AF" and "AB" terminfo entries to "%p".
(Benzinger).
- When running an external command from the GUI, typeahead is going to that
program, not to Vim. It looks like the shell eats the characters, Vim
can't get back what the external command didn't use.
- Win32 GUI: Error code from external command not returned in shell_error.
It appears that cmd.exe and command.com don't return an error code.
- Win32 GUI: The Toolbar is a bit too high when the flat style is being
used. We don't have control over the height of the Toolbar.
- Win32: All files created on the day of switching from winter to summer
time cause "changed since editing started" messages. It goes away when
the file is written again the next day, or the timezone is adjusted.
DJGPP version is OK. (Zaimi) Looks like a problem with the Win32 library.
Rebooting doesn't help. Time stamps look OK in directory. (Penn)
Is this on FAT (stores wall clock time) or NTFS (stores UTS)?
- Win32, MS-Windows XP: $HOME uses the wrong drive when the user profiles
are not on the boot disk. This is caused by a wrong value of $HOMEDRIVE.
This is a bug in XP, see MSKB article 818134.
- SunOS 5.5.1 with Motif: The file open dialog does not have a horizontal
scroll bar for the "files" selection. This is a problem in the Motif
libraries, get a patch from Sun.
- Solaris 2.6 with GTK and Perl: gvim crashes when started. Problem with X
input method called from GDK code. Without Perl it doesn't crash.
- VMS: Vimdiff doesn't work with the VMS diff, because the output looks
different. This makes test 47 fail. Install a Unix-compatible diff.
- VMS v7.1 and older: Tests 21 and 32 fail. From VMS v7.1-2 and newer Vim
does not have this behavior. (Zoltan Arpadffy)
- Win32 GUI: mouse wheel always scrolls rightmost window. The events arrive
in Vim as if the rightmost scrollbar was used.
- GTK with Gnome: Produces an error message when starting up:
Gdk-WARNING **: locale not supported by C library
This is caused by the gnome library gnome_init() setting $LC_CTYPE to
"en_US". Not all systems support this locale name, thus causing the
error. Hopefully a newer version of GTK/Gnome fixes this problem.
- GTK 2: With this mapping the hit-enter prompt is _sometimes_ below the
screen, at other times there is a grey area below the command line:
:nmap <F11> :if &guioptions=~'m' \| set guioptions-=m \| else \| set guioptions+=m \| endif<cr>
- GTK: When pasting a selection from Vim to xclipboard gvim crashes with a
ABRT signal. Probably an error in the file gdkselection.c, the assert
always fails when XmbTextListToTextProperty() fails. (Tom Allard)
- GTK 2: gives an assertion error for every non-builtin icon in the toolbar.
This is a GTK 2.4.x bug, fixed in GTK 2.4.2. (Thomas de Grenier de Latour)
- When using an xterm that supports the termresponse feature, and the 't_Co'
termcap option was wrong when Vim started, it will be corrected when the
termresponse is received. Since the number of colors changes, the
highlighting needs to be initialized again. This may cause colors defined
in the vimrc file to be lost.
- On Windows NT 4.0 the number of files passed to Vim with drag&drop and
"Edit with Vim" is limited. The maximum command line length is 255 chars.
-------------------------- 扩展及改进 ---------------------------
*extensions-improvements*
没有放到 Vim 7.0 里的功能:
- Add COLUMN NUMBERS to ":" commands ":line1,line2[col1,col2]cmd". Block
can be selected with CTRL-V. Allow '$' (end of line) for col2.
- Add DEBUGGER INTERFACE. Implementation for gdb by Xavier de Gaye.
Should work like an IDE. Try to keep it generic. Now found here:
http://clewn.sf.net.
And the idevim plugin/script.
To be able to start the debugger from inside Vim: For GUI run a program
with a netbeans connection; for console: start a program that splits the
terminal, runs the debugger in one window and reconnect Vim I/O to the
other window.
Wishes for NetBeans commands:
- make it possible to have 'defineAnnoType' also handle terminal colors.
- send 'balloonText' events for the cursor position (using CursorHold ?)
in terminal mode.
- ECLIPSE plugin. Problem is: the interface is very complicated. Need to
implement part in Java and then connect to Vim. Some hints from Alexandru
Roman, 2004 Dec 15. Should then also work with Oracle Jdeveloper, see JSR
198 standard http://www.jcp.org/en/jsr/detail?id=198.
Eclim does it: http://eclim.sourceforge.net/ (Eric Van Dewoestine)
Plugin that uses a terminal emulator: http://vimplugin.sf.net
And another one: http://www.satokar.com/viplugin/index.php
- STICKY CURSOR: Add a way of scrolling that leaves the cursor where it is.
Especially when using the scrollbar. Typing a cursor-movement command
scrolls back to where the cursor is.
- Running a shell command from the GUI still has limitations. Look into how
the terminal emulator of the Vim shell project can help:
http://vimshell.wana.at
- Add Lua interface? (Wolfgang Oertl)
8 Add a command to jump to a certain kind of tag. Allow the user to specify
values for the optional fields. E.g., ":tag size type=m".
Also allow specifying the file and command, so that the result of
taglist() can be used.
- X11: Make it possible to run Vim inside a window of another program.
This can be done with XReparentWindow(). But how exactly?
文档:
8 List of Vim runtime directories. dotvim.txt from Charles Campbell, 2007
Feb 20.
8 The GUI help should explain the Find and Find/Replace dialogs. Add a link
to it from ":promptrepl" and ":promptfind".
8 List of options should mention whether environment variables are expanded
or not.
8 Extend usr_27.txt a bit. (Adam Seyfarth)
7 Add a section on debugging scripts in the user manual.
9 Make the Reference Manual more precise. For each command mention:
- change to cursor position and curswant
- if it can be undone (u/CTRL-R) and redone (.)
- how it works for folded lines
- how it works with multi-byte characters
9 In change.txt, remark about Javadoc isn't right. Right alignment would
work too.
8 Spread the windows commands over the other files. For example, ":stag"
should be with ":tag". Cross-link with tags to avoid too much double
text.
8 Add tags for all features, e.g. "gui_running".
7 MS-Windows: When a wrong command is typed with an ALT key, give a hint to
look at the help for 'winaltkeys'.
7 Add a help.vim plugin that maps <Tab> to jump to the next tag in || and
<C-Tab> (and <S-Tab>) to the previous tag.
- Check text editor compendium for vi and Vim remarks.
帮助:
- First try using the ":help" argument literally, before using it as a
pattern. And then match it as part of a tag.
- When a help item has multiple matches make it possible to use ":tn" to go
to the other matches.
- Support a way to view (and edit) .info files.
- Default mapping for help files: <Tab> to position cursor on next |:tag|.
- Implement a "sticky" help window, some help text lines that are always
displayed in a window with fixed height. (Guckes) Use "~/.vimhelp" file,
user can edit it to insert his favorite commands, new account can contain a
default contents.
- Make 'winminheight' a local option, so that the user can set a minimal
height for the help window (and other windows).
- ":help :s^I" should expand to ":help :substitute".
- Make the help key (<F1>) context sensitive?
- Learn mode: show short help while typing commands.

8 Windows install with NSIS: make it possible to do a silent install, see
http://nsis.sourceforge.net/Docs/Chapter4.html#4.12
8 Windows install with install.exe: Use .exe instead of .bat files for
links, so that command line arguments are passed on unmodified? (Walter
Briscoe)
8 Windows install: Be able to associate Vim with a selection of file types?
8 Windows uninstall: Have uninstal.c delete the vimfiles directories that
dosinst.c creates. List the contents of the directory (recursively) if
the user asks for it. Requires an implementation of "rm -rf".
8 Remember the name of the vimrc file that was used (~/.vimrc, $VIM/_vimrc,
$HOME/_vimrc, etc.) and add "edit vimrc" to the File menu.
- Add a way to save local settings and mappings into a new plugin file.
":mkplugin <file>"?
8 Add ":plugininstall" command. Can be used to install a plugin file that
includes documentation. Let the user select a directory from
'runtimepath'.
" Vim plugin
<main plugin code>
" >>> plugin help start <<<
<plugin docs>
- Add mappings local to a window: ":map <window> ..."?
9 Add buffer-local menu. Should offer a choice between removing the menu or
disabling it. Be careful that tear-offs don't disappear (keep one empty
item?).
Alternative: use BufEnter and BufLeave autocommands.
8 make a vimtutor script for Amiga and other systems.
7 Add the arguments for configure to the ":version" output?
7 When Vim detects a file is being edited elsewhere and it's a gvim session
of the same user it should offer a "Raise" button, so that the other gvim
window can be displayed. (Eduard)
8 Support saving and restoring session for X windows? It should work to do
":mksession" and use "-S fname" for the restart command. The
gui_x11_wm_protocol_handler() already takes care of the rest.
global_event_filter() for GTK.

9 GUI implementation for the tab pages line for other systems.
7 GUI: Control over the appearance of the text in the labels (bold, color,
font, etc.)
9 Make it possible to drag a tab page label to another position with the
mouse.
8 Make GUI menu in tab pages line configurable. Like the popup menu.
8 balloons for the tab page labels that are shortened to show the full path.
8 :tabmove +N move tab page N pages forward
8 :tabmove -N move tab page N pages backward
7 :tabdup duplicate the tab with all its windows.
7 Option to put tab line at the left or right? Need an option to specify
its width. It's like a separate window with ":tabs" output.
7 Add local variables for each tab page?
8 Add local options for each tab page? E.g., 'diffopt' could differ between
tab pages.
7 Add local highlighting for each tab page?
7 Add local directory for tab pages? How would this interfere with
window-local directories?
拼写检查:
- Support more regions? Caolan McNamara argues it's needed for es_XX.
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=219777
- Unicode defines another quote character: 0x2019. Use it as an equivalent
of a single quote, thus use it as a word character like a quote and match
with words, replacing the curly quote with a single quote.
- Could filter é things for HTML before doing spell checking.
Similarly for TeX.
- The Hungarian spell file uses four extra characters in the FOL/UPP/LOW
items than other spell files with the ISO-8859-2 encoding, that causes
problem when changing 'spelllang'. There is no obvious way to fix this.
- Considering Hunspell 1.1.4:
What does MAXNGRAMSUGS do?
Is COMPLEXPREFIXES necessary when we have flags for affixes?
- There is no Finnish spell checking file. For openoffic Voikko is now
used, which is based on Malaga: http://home.arcor.de/bjoern-beutel/malaga/
(Teemu Likonen)
8 ":mkspell" still takes much too long in Hungarian dictionary from
hunspell. Only solution appears to be to postpone secondary suffixes.
8 Handle postponed prefix with COMPOUNDPERMITFLAG or COMPOUNDFORBIDFLAG.
WFP_COMPPERMIT and WFP_COMPFORBID
8 implement use of <compoptions> in .spl file:
implement CHECKCOMPOUNDREP: when a compound word seems to be OK apply REP
items and theck if the result is a valid word.
implement CHECKCOMPOUNDDUP
implement CHECKCOMPOUNDTRIPLE
Add CHECKCOMPOUNDCASE: when compounding make leading capital lower case.
How is it supposed to work?
8 implement using CHECKCOMPOUNDPATTERN: match words with sl_comppat[].
- Add a command the repeats ]s and z=, showing the misspelled word in its
context. Thus to spell-check a whole file.
- suggestion for "KG" to "kg" when it's keepcase.
- For flags on affixes: Use a "AFFCOMPSET" flag; means the compound flags of
the word are not used.
- Support breakpoint character ? 0xb7 and ignore it? Makes it possible to
use same wordlist for hyphenation.
- Compound word is accepted if nr of words is <= COMPOUNDWORDMAX OR nr of
syllables <= COMPOUNDSYLMAX. Specify using AND in the affix file?
- NEEDCOMPOUND also used for affix? Or is this called ONLYINCOMPOUND now?
Or is ONLYINCOMPOUND only for inside a compound, not at start or end?
- Do we need a flag for the rule that when compounding is done the following
word doesn't have a capital after a word character, even for Onecap words?
- New hunspell home page: http://hunspell.sourceforge.net/
- Version 1.1.0 is out now, look into that.
- Lots of code depends on LANG, that isn't right. Enable each mechanism
in the affix file separately.
- Example with compounding dash is bad, gets in the way of setting
COMPOUNDMIN and COMPOUNDWORDMAX to a reasonable value.
- PSEUDOROOT == NEEDAFFIX
- COMPOUNDROOT -> COMPOUNDED? For a word that already is a compound word
Or use COMPOUNDED2, COMPOUNDED3, etc.
8 Alternate Dutch word list at www.nederlandsewoorden.nl (use script to
obtain). But new Myspell wordlist will come (Hagen)
- CIRCUMFIX: when a word uses a prefix marked with the CIRCUMFIX flag, then
the word must also have a suffix marked with the CIRCUMFIX flag. It's a
bit primitive, since only one flag is used, which doesn't allow matching
specific prefixes with suffixes.
Alternative:
PSFX {flag} {pchop} {padd} {pcond} {schop} {sadd}[/flags] {scond}
We might not need this at all, you can use the NEEDAFFIX flag and the
affix which is required.
- When a suffix has more than one syllable, it may count as a word for
COMPOUNDWORDMAX.
- Add flags to count extra syllables in a word. SYLLABLEADD1 SYLLABLEADD2,
etc.? Or make it possible to specify the syllable count of a word
directly, e.g., after another slash: /abc/3
- MORPHO item in affix file: ignore TAB and morphological field after
word/flags and affix.
- Implement multiple flags for compound words and CMP item?
Await comments from other spell checking authors.
- Also see tklspell: http://tkltrans.sourceforge.net/
8 Charles Campbell asks for method to add "contained" groups to existing
syntax items (to add @Spell).
Add ":syntax contains {pattern} add=@Spell" command? A bit like ":syn
cluster" but change the contains list directly for matching syntax items.

8 Make "en-rare" spell file? Ask Charles Campbell.
8 The English dictionaries for different regions are not consistent in their
use of words with a dash.
7 Insert mode completion mechanism that uses the spell word lists.
8 Add hl groups to 'spelllang'?
:set spelllang=en_us,en-rare/SpellRare,en-math/SpellMath
More complicated: Regions with different languages? E.g., comments
in English, strings in German (po file).
Diff 模式:
8 Use diff mode to show the changes made in a buffer (compared to the file).
Use an unnamed buffer, like doing:
new | set bt=nofile | r # | 0d_ | diffthis | wincmd p | diffthis
Also show difference with the file when editing started? Should show what
can be undone. (Tom Popovich)
7 Add cursor-binding: when moving the cursor in one diff'ed buffer, also
move it in other diff'ed buffers, so that CTRL-W commands go to the same
location.
折叠:
(commands still available: zI zJ zK zp zP zq zQ zV zy zY;
secondary: zB zS zT zZ, z=)
8 Vertical folds: looks like vertically split windows, but the cursor moves
through the vertical separator, separator moves when scrolling.
8 Add "z/" and "z?" for searching in not folded text only.
9 Add search pattern item to only match in closed or open fold and/or fold
with certain level. Allows doing ":g/pat/cmd" to work on closed folds.
8 Add different highlighting for a fold line depending on the fold level.
(Noel Henson)
7 Use "++--", "+++--" for different levels instead of "+---" "+----".
8 When a closed fold is displayed open because of 'foldminlines', the
behavior of commands is still like the fold is closed. How to make the
user aware of this?
8 Add an option 'foldskip' with values like 'foldopen' that specifies which
commands skip over a closed fold.
8 "H" and "L" count buffer lines instead of window lines. (Servatius Brandt)
8 Add a way to add fold-plugins. Johannes Zellner has one for VB.
7 When using manual folding, the undo command should also restore folds.
- Allow completely hiding a closed fold. E.g., by setting 'foldtext' to an
empty string. Require showing a character in 'foldcolumn' to avoid the
missing line goes unnoticed.
How to implement this?
- When pressing the down arrow of a scrollbar, a closed fold doesn't scroll
until after a long time. How to make scrolling with closed folds
smoother?
- When creating a session, also store folds for buffers in the buffer list,
using the wininfo in wi_folds.
- When currently editing the first file in the argument list the session
file can contain:
args version.c main.c
edit version.c
Can editing version.c twice be avoided?
- 'foldmethod' "textobject": fold on sections and paragraph text objects.
- Add 'hidecomment' option: don't display comments in /* */ and after //.
Or is the conceal patch from Vince Negri a more generic solution?
- "zuf": undo change in manual fold. "zUf" redo change in manual fold. How
to implement this?
- "zJ" command: add the line or fold below the fold in the fold under the
cursor.
- 'foldmethod' "syntax": "fold=3" argument: set fold level for a region or
match.
- Apply a new foldlevel to a range of lines. (Steve Litt)
8 Have some way to restrict commands to not folded text. Also commands like
searches.
多字节字符处理:
- When editing a file with both utf-8 and latin1 text Vim always falls back
to latin1. Add a command to convert the latin1 characters to utf-8?
:unmix utf-8,latin1 filename
Would only work when 'encoding' is utf-8.
9 When the tail byte of a double-byte character is illegal (e.g., a CR), the
display is messed up (Yasuhiro Matsumoto). Should check for illegal
double-byte characters and display them differently (display each single
byte).
8 Add an item in 'fileencodings' to check the first lines of a file for
the encoding. See Python PEP: http://www.python.org/peps/pep-0263.html.
To avoid getting a wrong encoding only accept something Emacs-like:
"-*- coding: enc-na_me.foo -*-" and "-*- coding= enc-na_me.foo -*-"
Match with "-\*-\s*coding[:=]\s*\([::word::-_.]\+\)\s*-\*-" and use first
item.
8 Add an item in 'fileencodings' to check the first line of an XML file for
the encoding. <?xml version="1.0" encoding="UTF-8"?> Or "charset=UTF-8"?
For HTML look for "charset=utf-8".
8 The quickfix file is read without conversion, thus in 'encoding'. Add an
option to specify the encoding of the errorfile and convert it. Also for
":grep" and ":helpgrep".
More generic solution: support a filter (e.g., by calling a function).
8 When a file was converted from 'fileencoding' to 'encoding', a tag search
should also do this on the search pattern. (Andrzej M. Ostruszka)
7 When converting a file fails, mention which byte could not be converted,
so that the user can fix the problem.
8 Add configure option to be able to disable using the iconv library. (Udo
Schweigert)
9 'aleph' should be set to 1488 for Unicode. (Zvi Har'El)
8 Should add test for using various commands with multi-byte characters.
8 'infercase' doesn't work with multi-byte characters.
8 toupper() function doesn't handle byte count changes.
7 When searching, should order of composing characters be ignored?
8 Should implement 'delcombine' for command line editing.
8 Detect overlong UTF-8 sequences and handle them like illegal bytes.
8 ":s/x/\u\1/" doesn't work, making uppercase isn't done for multi-byte
characters.
8 UTF-8: "r" in Visual mode doesn't take composing characters.
8 UTF-8: When there is a precomposed character in the font, use it instead
of a character and a composing character. See xterm for an example.
7 When a character can't be displayed, display its digraph instead.
'display' option to specify this.
7 Use ideas for nl_langinfo() from Markus Kuhn in enc_default():
(www.cl.cam.ac.uk/~mgk25/ucs/langinfo.c)
- GTK and Win32: Allow selecting fonts for 'guifontset' with the
fontselector somehow.
- GTK and Win32: make it possible to set the font for the menu to make it
possible to have 'encoding' different from the current locale.
- dbcs_class() only works for Japanese and Korean. Implement this for
other encodings. The "euc-jp" and "euc-kr" choices might be wrong.
- Find some way to automatically select the right GUI font or fontset,
depending on the default value of 'encoding'.
Irrelevant in the GTK+ 2 GUI so long as UTF-8 is used.
For Windows, the charset_pairs[] table could be used. But how do we know
if a font exists?
- Do keyboard conversion from 'termencoding' to 'encoding' with
convert_input() for Mac GUI and RiscOS GUI.
- Add mnemonics from RFC1345 longer than two characters.
Support CTRL-K _{mnemonic}_
7 In "-- INSERT (lang) --" show the name of the keymap used instead of
"lang". (Ilya Dogolazky)
- Make 'langmap' accept multi-byte characters.
Patch from Konstantin Korikov, 2006 Oct 15.
- Make 'breakat' accept multi-byte characters. Problem: can't use a lookup
table anymore (breakat_flags[]).
Simplistic solution: when 'formatoptions' contains "m" also break a line
at a multi-byte character >= 0x100.
- Do we need the reverse of 'keymap', like 'langmap' but with files and
multi-byte characters? E.g., when using a Russian keyboard.
- Add the possibility to enter mappings which are used whenever normal text
could be entered. E.g., for "f" command. But not in Normal mode. Sort
of opposite of 'langmap'. Use ":tmap" command?
- When breaking a line, take properties of multi-byte characters into
account. The "linebreak" program from Bruno Haible can do it:
ftp://ftp.ilog.fr/pub/Users/haible/gnu/linebreak-0.1.tar.gz
But it's very complicated...
打印:
7 Implement "undercurl" for printing.
- Add "page width" to wrap long lines.
- Win32: use a font dialog for setting 'printfont'. Can reuse the code for
the 'guifont' dialog, put the common code in a separate function.
- Add the file timestamp to the page header (with an option). (George
Reilly)
- Win32: when 'printfont' is empty use 'guifont'.
- Unix: Use some dialog box to do the obvious settings (paper size, printer
name, portrait/landscape, etc).
- PostScript: Only works for text that can be converted to an 8-bit
character set. How to support Unicode fully?
- Allow specifying the paper size, instead of using a standard size. Same
units as for the margins.
- Support right-to-left text?
8 Make the foreground color darkening function preserve the hue of the
color.
语法高亮:
8 Make ":syn off" use 'runtimepath' instead of $VIMRUNTIME. (Gary Johnson)
Should do the same for ":syn on" and ":syn manual".
8 Support "containedin" argument for ":syn include", so that the defined
cluster can be added to existing syntax items.
8 C syntax: Don't highlight {} as errors inside () when used like this:
"({ something })", often used in GCC code.
7 Add a "startgroup" to a region. Used like "nextgroup" inside the region,
preferred item at the start of the region. (Charles Campbell)
8 When editing a new file without a name and giving it a name (by writing
it) and 'filetype' is not set, detect the filetype. Avoid doing it for
":wq file".
7 For "nextgroup" we have skipwhite, skipnl and skipempty. It would be
really nice to be able to skip with a pattern. Or skip with a syntax
group. (Nikolai Weibull, 2007 Feb 27)
8 Make conversion to HTML faster (Write it in C or pre-compile the script).
9 There is still a redraw bug somewhere. Probably because a cached state is
used in a wrong way. I can't reproduce it...
7 Be able to change only the background highlighting. Useful for Diff* and
Search highlighting.
7 When 'number' is set highlight the number of the current line.
Must be enabled with an option, because it slows down display updating.
8 Allow the user to add items to the Syntax menu sorted, without having to
change this for each release.
8 Add a "matchcontains" for regions: items contained in the start or end
pattern, but not in the body.
8 Add a "keepend-contained" argument: Don't change the end of an item this
one is contained in. Like "keepend" but specified on the contained item,
instead of the containing item.
8 cpp.vim: In C++ it's allowed to use {} inside ().
8 Some syntax files set 'iskeyword'. When switching to another filetype
this isn't reset. Add a special keyword definition for the syntax rules?
When this is done, use vim.vim syntax highlighting for help file examples,
but without ":" in 'iskeyword' for syntax.
8 Add specific syntax item to match with parens/braces that don't have a
"%" match. :syntax nomatch cMatchError (,{,[,),},] [contained]
8 Highlight the text between two matching parens (e.g., with a grey
background) when on one of the parens or in between them.
Option for the matchparen plugin?
8 Add a command to jump to the next character highlighted with "Error".
8 When using a cterm, and no ctermfg or ctermbg are defined, use start/stop
sequences. Add remark in docs that :if 'term' == "term-name" should be
used.
8 Add @spell cluster to String and Comment groups for many languages. Will
allow spell checking. (Fleiner)
8 When listing syntax items, try to sort the keywords alphabetically. And
re-insert the [] if possible.
8 Make it possible to use color of text for Visual highlight group (like for
the Cursor).
8 It would be useful to make the highlight group name an expression. Then
when there is a match, the expression would be evaluated to find out what
highlight group to use. Could be used to check if the shell used in a
password file appears in /etc/shells. (Nikolai Weibull)
syn match =s:checkShell(v:match) contained 'pattern'
8 Make it possible to only highlight a sub-expression of a match. Like
using "\1" in a ":s" command.
8 Support for deleting syntax items:
:syn keyword cTodo remove this
:syn match cTodo remove "pattern"
:syn region cString remove start="this" end="that"
8 Add possibility to sync on something else, when the syncing in one way
doesn't find match. For HTML: When no {script} is found, try looking for
a '<'. (Fleiner)
7 Replace the synchronizing method with a state machine specification?
Should be able to start at any line in the file, search forwards or
backwards, and use the result of matching a pattern.
7 Use parsing like awk, so that e.g., a ( without a matching ) can be
detected.
8 Make it possible to use "inverted" highlighting, invert the original
character. For Visual mode. (xterm-selection already does this).
8 Highlight non-printable characters with "SpecialChar", linked to
"Special". Display them with the digraph characters, if possible.
8 Highlight the clipboard-selection with a highlight group.
8 Be able to reset highlighting to its original (default) values.
7 Be able to write current highlighting to a file as commands, similar to
":mkvimrc".
8 Improve c.vim:
- Add check for unterminated strings, with a variable to switch it on:
"c_strict_ansi".
- Detect unbalanced "#endif". Requires looking back a long way...
8 Add an option to restrict the updating of syntax highlighting to the
current line while in Insert mode.
8 When guessing value of 'background', the syntax file has already been
loaded (from the .gvimrc). After changing 'background', load it again?
8 Add ":syn resync" command, to re-parse the whole file until the current
display position.
8 Should support "me" offset for a region start pattern. To be used to
allow searching for the end pattern inside the match of the end pattern.
Example: syn region pikeXX start="([^{]" end=")" should work on "()".
8 When using a regexp for "contains=", should delay matching with it until
redrawing happens. Set a flag when a group is added, check this flag when
highlighting starts.
8 Some terminals can display colors like the GUI. Add some setting to use
GUI colors for the terminal? With something to define the escape
sequence.
7 It's possible for an item to be transparent, so that the colors of an item
lower on the stack is used. Also do this with highlighting, so that the
user can set transparent highlighting? E.g. a number in a C comment would
get the color of a comment, a number in an assignment Normal. (Nikolai
Weibull)
7 Add "semitrans": Add highlighting. E.g., make the text bold, but keep the
colors. And add colors, so that Green+Red becomes Yellow.
E.g. for this html:
<B> bold text <I> italic+bold text </B> italic text </I>
7 Wild idea: Not only set highlighting, but also change what is displayed
(e.g., remove characters, so that "<B>bold</B>" can be shown as "bold"):
:syn region boldstuff start="<B>" display="" end="</B>" display=""
7 CTRL-] checks the highlight group for finding out what the tag is.
7 Add an explanation how a list of words can be used to highlight misspelled
words.
8 Add more command line completion for :syntax.
8 Add more command line completion for :highlight.
8 Add more command line completion for :sign.
7 Should find a better way to parse the :syntax and :highlight commands.
Use tables or lists that can be shared by parsing for execution and
completion?
8 Add ColorSchemePost autocommand event, so that scripts can set up their
highlighting. (Salman Halim)
7 Add a few sets of colors (e.g. Borland Turbo C one). With a menu to
select one of the sets.
8 Add offsets to sub-matches: "\(a*\) *"he=e1-1
'e' is end of match 'e1' is end of sub-match 1, 's2' is start of submatch
2, etc.
8 In Insert mode, when there are typeahead characters, postpone the
highlighting (for "." command).
8 Syncing on comments isn't 100% correct when / / lines mix with / * and * /.
For example: What about a line that starts with / / and contains * /?
8 Ignore / * and * / inside strings, when syncing.
7 Build a few more syntax files from the file "/usr/share/misc/vgrindefs":
ISP, LDL, Icon, ratfor. And check "nedit/source/highlight.c".
6 Add possibility to have background color continue until the right edge of
the window. Useful for comment blocks and function headings. (Rogall)
- Make it possible to add "contains" items for all items in a group. Useful
when extending an already existing syntax file.
- Add line-continuation pattern for non-syncing items too?
- Add possibility to highlight the whole line, including the right margin
(for comment blocks).
- Add 'hlmatch' option: List of flags:
'c': highlight match for character under the cursor.
'b': highlight the previous (, and its match.
'a': highlight all text from the previous ( until its match.
Also for {}, <>, etc.?
'e': highlight all braces without a match (slow?)
OR: add an argument "cursor" to the syntax command, which means that the
region/match/keyword is only highlighted when the cursor is on it.
(Campbell)
Or do it like Elvis: define text objects and how to highlight them around
the cursor. (Iain Truskett)
7 Make it possible to use all words in the tags files as Keyword.
Can also be done with a script (but it's slow).
7 Make it possible to call a ":" command when a match is found. Should
allow for adding keywords from the text (e.g. variables that are set).
And allows for sections with different highlighting.
7 Add highlight group for commandline: "Commandline". Make sure it
highlights the command line while typing a command, and any output from
messages. And external commands?
8 Make a version that works like less, but with highlighting: read stdin for
text, exit at end of file, don't allow editing, etc. moreim? lessim?
7 SpecialKey highlighting overrules syntax highlighting. Can't give an
unprintable char another color. Would be useful for ^M at end of line.
内建脚本语言:
7 Execute a function with standard option values. No need to save and
restore option values. Especially useful for new options. Problem: how
to avoid a performance penalty (esp. for string options)?
8 Add referring to key options with "&t_xx". Both for "echo &t_xx" and
":let &t_xx =". Useful for making portable mappings.
- Add ":let var ?= value", conditional assignment. Patch by Dave Eggum,
2006 Dec 11.
- range for ":exec", pass it on to the executed command. (Webb)
7 ":include" command: just like ":source" but doesn't start a new scriptID?
Will be tricky for the list of script names.
8 Have a look at VSEL. Would it be useful to include? (Bigham)
8 Add ":fungroup" command, to group function definitions together. When
encountered, all functions in the group are removed. Suggest using an
obscure name to avoid name clashes. Require a ":fungroup END" in the same
sourced file? Assume the group ends at the end of the file. Handle
nested packages?
Alternative: Support packages. {package-name}:{function-name}().
Packages are loaded automatically when first used, from
$VIMRUNTIME/packages (or use a search path).
7 Pre-parse or compile Vim scripts into a bytecode.
1. Put the bytecode with the original script, with an ":if
has('bytecode')" around it, so that it's only used with a Vim that
supports it. Update the code with a command, can be used in an
autocommand.
2. Use a ".vic" file (like Python use .pyc). Create it when writing a
.vim file. Problem: distribution.
3. Use a cache directory for each user. How to recognize which cached
file belongs to a sourced script?
7 Add argument to winwidth() to subtract the space taken by 'foldcolumn',
signs and/or 'number'.
6 Add ++ and -- operators? They only work on variables (lvals), how to
implement this?
8 Add functions:
has(":command") Check if ":command" works. compare function
with "ex_ni". E.g. for ":simalt".
system() With a List argument. Bypasses the shell, use
exec() directly. (Bob Hiestand)
escape() Add argument to specify what to escape with.
modestack() Instead of just the current mode return the
stack of Insert / CTRL-O / :normal things.
realname() Get user name (first, last, full)
user_fullname() patch by Nikolai Weibull, Nov
3 2002
Only add this when also implemented for
non-Unix systems, otherwise a shell cmd could
be used.
get_user_name() gets login name.
menuprop({name}, {idx}, {what})
Get menu property of menu {name} item {idx}.
menuprop("", 1, "name") returns "File".
menuprop("File", 1, "n") returns "nmenu
File.Open..." argument.
Patch by Ilya Sher, 2004 Apr 22
Return a list of menus and/or a dictionary
with properties instead.
mapname({idx}, mode) return the name of the idx'th mapping.
Patch by Ilya Sher, 2004 Mar 4.
Return a list instead.
char2hex() convert char string to hex string.
attributes() return file protection flags "drwxrwxrwx"
filecopy(from, to) Copy a file
shorten(fname) shorten a file name, like home_replace()
perl(cmd) call Perl and return string
inputrl() like input() but right-to-left
virtualmode() add argument to obtain whether "$" was used in
Visual block mode.
getacp() Win32: get codepage (Glenn Maynard)
deletebufline() delete line in any buffer
appendbufline() append line in any buffer
libcall() Allow more than one argument.
libcallext() Like libcall(), but using a callback function
to allow the library to execute a command or
evaluate an expression.
7 Make bufname("'0") return the buffer name from mark '0. How to get the
column and line number? col("'0") currently returns zero.
8 argc() returns 0 when using "vim -t tag". How to detect that no file was
specified in any way? To be able to jump to the last edited file.
8 Pass the command line arguments to Vim scripts in some way. As v:args
List? Or extra parameter to argv()?
8 Add command arguments with three dashes, passed on to Vim scripts.
7 Add optional arguments to user functions:
:func myFunc(arg1, arg2, arg3 = "blah", arg4 = 17)
6 User functions: Functions local to buffer "b:func()"?
8 For Strings add ":let var[{expr}] = {expr}". When past the end of "var"
just ignore.
8 The "= register should be writable, if followed by the name of a variable,
option or environment variable.
8 ":let &option" should list the value of the option.
8 ":let Func().foo = value" should work, also when "foo" doesn't exist.
7 Add synIDlist(), making the whole list of syntax items on the syntax stack
available as a List.
8 Add autocommand-event for when a variable is changed:
:au VarChanged {varname} {commands}
8 Add "has("gui_capable")", to check if the GUI can be started.
8 Add possibility to use variables like registers: characterwise (default),
linewise (when ending in '\n'), blockwise (when ending in '\001'). reg0,
rega, reg%, etc. Add functions linewise({expr}), blockwise({expr}) and
charwise({expr}).
7 Make it possible to do any command on a string variable (make a buffer
with one line, containing the string). Maybe add an (invisible) scratch
buffer for this?
result = scratch(string, command)
result = apply(string, command)
result = execute(string, command)
"command" would use <> notation.
Does scratch buffer have a number? Or re-use same number?
7 Add function to generate unique number (date in milliseconds).
7 Automatically load a function from a file when it is called. Need an
option for the search path. (Sekera)
健壮性:
6 Add file locking. Lock a file when starting to edit it with flock() or
fcntl(). This patch has advisory file locking while reading/writing
the file for Vim 5.4: ~/vim/patches/kahn_file_locking .
The patch is incomplete (needs support for more systems, autoconf).
Andy doesn't have time to work on it.
Disadvantage: Need to find ways to gracefully handle failure to obtain a
lock. When to release a lock: When buffer is unloaded?
性能:
7 For strings up to 3 bytes don't allocate memory, use v_list itself as a
character array. Use VAR_SSTRING (short string).
8 Instead of loading rgb.txt every time a color wasn't recognized load it
once and keep it in memory. Move the code to a common place to avoid
repeating it in various system files.
8 Turn b_syn_ic and b_syn_containedin into b_syn_flags.
9 Loading menu.vim still takes quite a bit of time. How to make it faster?
8 in_id_list() takes much time for syntax highlighting. Cache the result?
7 setpcmark() shifts the jumplist, this takes quite a bit of time when
jumping around. Instead use an index for the start?
8 When displaying a space with only foreground highlighting, it's the same
as a space without attributes. Avoid displaying spaces for the "~" lines
when starting up in a color terminal.
8 Avoid alloc() for scratch buffer use, esp. in syntax.c. It's very slow on
Win16.
9 Setting GUI options in the console (e.g., 'guifont') should not cause a
redraw.
8 Profiling shows that in_id_list() is used very often for C code. Can this
function be improved?
8 For an existing file, the page size of the swap file is always the
default, instead of using the block size of the device, because the swap
file is created only after setting the block size in mf_open(). How can
this be improved?
8 Set default for 'ttyscroll' to half a screen height? Should speed up
MS-DOS version. (Negri)
7 C syntax highlighting gets a lot slower after ":set foldmethod=syntax".
(Charles Campbell) Inserting a "{" is very slow. (dman)
7 HTML syntax highlighting is slow for long lines. Try displaying
http://www.theregister.co.uk/content/4/22908.html. (Andre Pang)
7 Check how performance of loading the wordlist can be improved (adding a
lot of abbreviations).
7 DOS console: Add t_DL support, to make scrolling faster.
7 Compile Ex commands to byte codes. Store byte codes in a vim script file
at the end, after "compiled:. Make it look like a single comment line
for old Vim versions. Insert first line "Vim script compiled <timestamp>.
Only used compiled code when timestamp matches the file stat.
Add command to compile a vim script and add it to the file in-place.
Split Ex command executing into a parsing and executing phase.
Use compiled code for functions, while loops, etc.
8 When editing a file with extremely long lines (e.g., an executable), the
"linerest" in readfile() is allocated twice to be able to copy what was
read so far. Use realloc() instead? Or split the line when allocating
memory fails and "linerest" is big (> 100000)?
8 When defining autocommands (e.g., from $VIMRUNTIME/filetype.vim), need to
compare each pattern with all existing patterns. Use a hash code to avoid
using strcmp() too often?
7 Include turbo_loader patches, speeding up reading a file?
Speed up reading a file by reading it into a fixed-size buffer, creating
the list of indexes in another buffer, and then copying the result into a
memfile block with two copies. Then read the next block into another
fixed-size buffer, create the second list of indexes and copy text from
the two blocks to the memfile block.
7 do_cmdline(): Avoid that the command line is copied to allocated memory
and freed again later all the time. For while loops, and for when called
with an argument that can be messed with.
Generic solution: Make a struct that contains a pointer and a flag that
indicates if the pointer should be freed when replaced.
7 Check that the file size is not more than "sizeof(long)".
- Further improve finding mappings in maphash[] in vgetorpeek()
8 Syntax highlighting is slow when deleting lines. Try in
$VIMRUNTIME/filetype.vim.
- "out of memory" after deleting (1,$d) and changing (:%s/^/> /) a lot of
lines (27000) a few times. Memory fragmentation?
- Have a look at how pdksh does memory allocation (alloc.c). (Dalecki)
- Do profiling on:
- :g/pat/normal cmd
- 1000ii<Esc>
- deleting 10Mbyte worth of lines (netscape binary)
- "[i" and "[d" (Yegappan Lakshmanan)
- ":g/^/m0" on a 450Kbyte file. And the "u".
- highlighting "~/vim/test/longline.tex", "~/vim/test/scwoop.tcl" and
"~/vim/test/lockup.pl".
- loading a syntax file to highlight all words not from a dictionary.
- editing a Vim script with syntax highlighting on (loading vim.vim).
7 Screen updating can be further improved by only redrawing lines that were
changed (and lines after them, when syntax highlighting was used, and it
changed).
- On each change, remember start and end of the change.
- When inserting/deleting lines, remember begin, end, and line count.
- Use macros/duarte/capicua for profiling. Nvi 1.71 is the fastest!
- When using a file with one long line (1Mbyte), then do "$hhhh", is still
very slow. Avoid calling getvcol() for each "h"?
- Executing a register, e.g. "10000@@" is slow, because ins_typebuf has to
move the previous commands forward each time. Pass count from
normal_cmd() down to do_execreg().
- Repeating insert "1000i-<Esc>" displays --INSERT-- all the time, because of
the <Esc> at the end. Make this work faster (disable redrawing).
- Avoid calls to plines() for cursor line, use w_cline_height.
- After ":set nowrap" remove superfluous redraw with wrong hor. offset if
cursor is right of the screen.
8 Make CTRL-C on Unix generate a signal, avoid using select() to check for a
CTRL-C (it's slow).
代码大小:
8 GUI: When NO_CONSOLE is defined, more code can be excluded.
- Put getline() and cookie in a struct, so only one argument has to be
passed to do_cmdline() and other functions.
8 Make a GUI-only version for Unix?
8 In buf_write _() isn't needed when setting errmsg, do it once when using
it.
7 When compiling with a GUI-only version, the code for cterm colors can be
left out.
8 When compiled with a GUI-only version, the termcap entries for terminals
can be removed.
8 Can the check for libelf in configure.in be removed?
消息:
8 When using ":q" in a changed file, the error says to "add !". Add the
command so that beginners understand it: "use :q!".
8 For 'verbose' level 12 prints commands from source'ed files. How to skip
lines that aren't executed? Perhaps move the echoing to do_cmdline()?
8 Use 'report' for ":bdel"? (Krishna) To avoid these messages when using a
script.
- Delete message after new command has been entered and have waited for key.
Perhaps after ten seconds?
- Make message history available in "msg" variables: msg1, msg2, .. msg9.
8 When reading from stdin allow suppressing the "reading from stdin"
message.
9 Check handling of overwriting of messages and delays:
Very wrong: errors while redrawing cause endless loop.
When switching to another file and screen scrolls because of the long
message and return must be typed, don't scroll the screen back before
redrawing.
7 Add an option, which is a regexp, that disables warning messages which
match that regexp (Tsirkin).
8 When address range is wrong you only get "Invalid range". Be a bit more
specific: Negative, beyond last line, reverse range? Include the text.
8 Make it possible to ignore errors for a moment ('errorignore'?). Another
option to switch off giving error messages ('errorquiet'?). Also an option
not to give any messages ('quiet')? Or ":quiet on", ":quiet off".
Careful: For a severe error (out of memory), and when the user starts
typing, error messages must be switched back on.
Also a flag to ignore error messages for shell commands (for mappings).
- Option to set time for emsg() sleep. Interrupt sleep when key is typed?
Sleep before second message?
8 In Ex silent mode or when reading commands from a file, what exactly is
not printed and what is? Check ":print", ":set all", ":args", ":vers",
etc. At least there should be no prompt. (Smulders) And don't clear the
screen when reading commands from stdin. (Kendall)
--> Make a difference between informative messages, prompts, etc. and
error messages, printing text, etc.
8 Window should be redrawn when resizing at the hit-enter prompt.
Also at the ":tselect" prompt. Find a generic solution for redrawing when
a prompt is present (with a callback function?).
屏幕刷新:
7 Add a string to the 'display' option to make CTRL-E and CTRL-Y scroll one
screen line, also if this means the first line doesn't start with the
first character (like what happens with a single line that doesn't fit).
- screen_line():
- insert/delete character stuff.
- improve delete rest of line (spaces at end of line).
- When moving or resizing window, try to avoid a complete redraw (esp. when
dragging the status line with the mouse).
- When 'lazyredraw' set, don't echo :ex commands? Need a flag to redraw when
waiting for a character.
8 Add a ":refresh [winnr]" command, to force updating a window. Useful from
an event handler where ":normal" can't be used. Also useful when
'lazyredraw' is set in a mapping.
7 Make 'list' and 'linebreak' work together.
滚动:
8 Add "zm" command: scroll horizontally to put the cursor in the middle.
6 Add option to set the overlap for CTRL-F and CTRL-B. (Garhi)
- extend 'scrollbind' option: 'scrollopt' words "search", "relative", etc..
Also 'e'xecute some commands (search, vertical movements) in all bound
windows.
7 Add 'scrollbind' feature to make the offset of one window with the next
one equal to the window height. When editing one file in both windows it
looks like each window displays a page of the buffer.
- Allow scrolling by dragging with the mouse (grab a character and move it
up/down). Like the "hand" in Acrobat reader. Use Alt-LeftMouse for this?
(Goldfarb)
- Add command to execute some commands (search, vertical movements) in all
bound windows.
- Add 'search' option to 'scrollopt' to allow 'scrollbind' windows to
be bound by regexp searches
- Add "z>" and "z<": scroll sideways one screenful. (Campbell)
- Add option to set the number of lines when not to scroll, instead of the
fixed number used now (for terminals that scroll slow with a large number
of lines but not with a single line).
Autoconf:
8 Should use acconfig.h to define prototypes that are used by autoheader.
8 Some compilers don't give an error for "-OPT:Olimit" but a warning. (Webb)
Add a check for the warning, so that "Olimit" can be added automatically?
- Autoconf: Use @datadir@ for the system independent files. Make sure the
system dependent and system independent files are separated. (Leitner).
- Add autoconf check for waitpid()/wait4().
- Remove fcntl() from autoconf, all systems have it?
- Set default for 'dictionary', add search for dictionary to autoconf.
Perl 接口:
8 Rename typemap file to something else?
7 Make buffers accessed as Perl arrays. (Clark)
7 Make it possible to compile with non-ANSI C?
6 Tcl/Tk has the "load" command: load a shared library (.so or .dll).
共享库:
6 Add support for loading shared libraries, and calling functions in it.
:libload internal-name libname
:libunload internal-name
