==============================================================================
INCOMPATIBLE CHANGES				*incompatible-7*

These changes are incompatible with previous releases.  Check this list if you
run into a problem when upgrading from Vim 6.x to 7.0.

A ":write file" command no longer resets the 'modified' flag of the buffer,
unless the '+' flag is in 'cpoptions' |cpo-+|.  This was illogical, since the
buffer is still modified compared to the original file.  And when undoing
all changes the file would actually be marked modified.  It does mean that
":quit" fails now.

":helpgrep" now uses a help window to display a match.

In an argument list double quotes could be used to include spaces in a file
name.  This caused a difference between ":edit" and ":next" for escaping
double quotes and it is incompatible with some versions of Vi.
	Command			Vim 6.x	file name	Vim 7.x file name ~
	:edit foo\"888          'foo"888'         	'foo"888'
	:next foo\"888          'foo888'          	'foo"888'
	:next a\"b c\"d         'ab cd'           	'a"b' and 'c"d'

In a |literal-string| a single quote can be doubled to get one.
":echo 'a''b'" would result in "a b", but now that two quotes stand for one it
results in "a'b".

When overwriting a file with ":w! fname" there was no warning for when "fname"
was being edited by another Vim.  Vim now gives an error message |E768|.


Minor incompatibilities:

For filetype detection: For many types, instead of ~/.dir/filename use
*/.dir/filename, so that it also works for other user's files.

":0verbose" now sets 'verbose' to zero instead of one.

Removed the old and incomplete "VimBuddy" code.

Buffers without a name report "No Name" instead of "No File".  It was
confusing for buffers with a name and 'buftype' set to "nofile".

When ":file xxx" is used in a buffer without a name, the alternate file name
isn't set.  This avoids creating buffers without a name that are not useful.

The "2html.vim" script now converts closed folds to HTML.  This means the HTML
looks like its displayed, with the same folds open and closed.  Use "zR", or
"let html_ignore_folding=1", if no folds should appear in the HTML. (partly by
Carl Osterwisch)
Diff mode now is also converted as it is displayed.

Win32: The effect of the <F10> key depended on 'winaltkeys'.  Now it depends
on whether <F10> has been mapped or not.  This allows mapping <F10> without
changing 'winaltkeys'.

When 'octal' is in 'nrformats' and using CTRL-A on "08" it became "018", which
is illogical.  Now it becomes "9".  The leading zero(s) is(are) removed to
avoid the number becoming octal after incrementing "009" to "010".

When 'encoding' is set to a Unicode encoding, the value for 'fileencodings'
now includes "default" before "latin1".  This means that for files with 8-bit
encodings the default is to use the encoding specified by the environment, if
possible.  Previously latin1 would always be used, which is wrong in a
non-latin1 environment, such as Russian.

Previously Vim would exit when there are two windows, both of them displaying
a help file, and using ":quit".  Now only the window is closed.

"-w {scriptout}" only works when {scriptout} doesn't start with a digit.
Otherwise it's used to set the 'window' option.

Previously <Home> and <xHome> could be mapped separately.  This had the
disadvantage that all mappings (with modifiers) had to be duplicated, since
you can't be sure what the keyboard generates.  Now all <xHome> are internally
translated to <Home>, both for the keys and for mappings.  Also for <xEnd>,
<xF1>, etc.

":put" now leaves the cursor on the last inserted line.

When a .gvimrc file exists then 'compatible' is off, just like when a ".vimrc"
file exists.

When making a string upper-case with "vlllU" or similar then the German sharp
s is replaced with "SS".  This does not happen with "~" to avoid backwards
compatibility problems and because "SS" can't be changed back to a sharp s.

==============================================================================
NEW FEATURES						*new-7*

Vim script enhancements					*new-vim-script*
-----------------------

In Vim scripts the following types have been added:

	List		ordered list of items |List|
	Dictionary	associative array of items |Dictionary|
	Funcref		reference to a function |Funcref|

Many functions and commands have been added to support the new types.

The |string()| function can be used to get a string representation of a
variable.  Works for Numbers, Strings and composites of them.  Then |eval()|
can be used to turn the string back into the variable value.

The |:let| command can now use ":let var += expr" like using ":let var = var +
expr".  "-=" and ".=" works in a similar way.

With the |:profile| command you can find out where your function or script
wastes its time.


Spell checking						*new-spell*
--------------

Spell checking has been integrated in Vim.  There were a few implementations
with scripts, but they were slow and/or required an external program.

The 'spell' option is used to switch spell checking on or off.
The 'spelllang' option is used to specify the languages that are accepted.
The 'spellfile' option specifies where new words are added.
The 'spellsuggest' option specifies the methods used for making suggestions

The |[s| and |]s| commands can be used to move to the next or previous error.
The |zg| and |zw| commands can be used to add good and wrong words.
The |z?| command can be used to correct the word.
The |:mkspell| command is used to generate a Vim spell file from word lists.

The "undercurl" highlighting attribute was added to nicely point out spelling
mistakes in the GUI (based on patch from Marcin Dalecki).
The "guisp" color can be used to give it a color different from foreground and
background.
The number of possible different highlight attributes was raised from about
220 to over 30000.  This allows for the attributes of spelling to be combined
with syntax highlighting attributes.  This is also used for syntax
highlighting.

Much more info here: |spell|.


KDE support						*new-KDE*
-----------

Kvim is the KDE version of Vim.  It uses the Qt toolkit.  See |KVim|.
(Thomas Capricelli, Philippe Fremy, Mickael Marchand, Mark Westcott, et al.)


MzScheme interface					*new-MzScheme*
------------------

The MzScheme interpreter is supported. |MzScheme|
The |:mzscheme| command can be used to execute MzScheme commands.
The |:mzfile| command can be used to execute an MzScheme script file.


Printing multi-byte text				*new-print-multi-byte*
------------------

The |:hardcopy| command now supports printing multi-byte characters.
The 'printmbcharset' and 'printmbfont' options are used for this.
Also see |postscript-cjk-printing|.  (Mike Williams)


Translated manual pages					*new-manpage-trans*
-----------------------

The manual page of Vim and associated programs is now also available in
several other languages.

French  - translated by David Blanchet
Italian - translated by Antonio Colombo
Russian - translated by Vassily Ragosin

The Unix Makefile installs the Italian manual pages in .../man/it/man1/,
.../man/it.ISO8859-1/man1/ and .../man/it.UTF-8/man1/.  There appears to be no
standard for what encoding goes in the "it" directory, the 8-bit encoded file
is used there as a best guess.
Other languages are installed in similar places.
The translated pages are not automatically installed when Vim was configured
with "--disable-nls", but "make install-languages install-tool-languages" will
do it anyway.


Internal grep						*new-vimgrep*
-------------

The ":vimgrep" command can be used to search for a pattern in a list of files.
This is like the ":grep" command, but no external program is used.  Besides
better portability, handling of different file encodings and using multi-line
patterns, this also allows grepping in compressed and remote files.
|:vimgrep|.

If you want to use the search results in a script you can use the
|getqflist()| function.

To search in files in various directories the "**" pattern can be used.  It
expands into an arbitrary depth of directories.  "**" can be used in all
places where file names are expanded, thus also with |:next| and |:args|.


Scroll back in messages					*new-scroll-back*
-----------------------

When displaying messages, at the |more-prompt| and the |hit-enter-prompt|, The
'k', 'u' and 'b' keys can be used to scroll back to previous messages.  This
is especially useful for commands such as ":syntax", ":autocommand" and
":highlight".  This is implemented in a generic way thus it works for all
commands and highlighting is kept.  Only works when the 'more' option is set.
Previously it only partly worked for ":clist".

The |g<| command can be used to see the last page of messages after you have
hit <Enter> at the |hit-enter-prompt|.  Then you can scroll further back.


POSIX compatibility					*new-posix*
-------------------

The POSIX test suite was used to verify POSIX compatibility.  A number of
problems have been fixed to make Vim more POSIX compatible.  Some of them
conflict with traditional Vi or expected behavior.  The $VIM_POSIX environment
variable can be set to get POSIX compatibility.  See |posix|.

Items that were fixed for both Vi and POSIX compatibilty:
- repeating "R" with a count only overwrites text once; added the 'X' flag to
  'cpoptions' |cpo-X|
- a vertical movement command that moves to a non-existing line fails; added
  the '-' flag to 'cpoptions' |cpo--|
- when preserving a file and doing ":q!" the file can be recovered; added the
  '&' flag to 'cpoptions' |cpo-&|
- The 'window' option is partly implemented.  It specifies how much CTRL-F and
  CTRL-B scroll when there is one window.  The "-w {number}" argument is now
  accepted.  "-w {scriptout}" only works when {scriptout} doesn't start with a
  digit.
- Allow "-c{command}" argument, no space between "-c" and {command}.
- When writing a file with ":w!" don't reset 'readonly' when 'Z' is present in
  'cpoptions'.
- Allow 'l' and '#' flags for ":list", ":print" and ":number".
- Added the '.' flag to 'cpoptions': ":cd" fails when the buffer is modified.
- In Ex mode with an empty buffer ":read file" doesn't keep an empty line
  above or below the new lines.
- Remove a backslash before a NL for the ":global" command.
- When ":append", ":insert" or ":change" is used with ":global", get the
  inserted lines from the command.  Can use backslash-NL to separate lines.
- Can use ":global /pat/ visual" to execute Normal mode commands at each
  matched line.  Use "Q" to continue and go to the next line.
- The |:open| command has been partially implemented.  It stops Ex mode, but
  redraws the whole screen, not just one line as open mode is supposed to do.
- Support using a pipe to read the output from and write input to an external
  command.  Added the 'shelltemp' option and has("filterpipe").
- In ex silent mode the ":set" command output is displayed.
- The ":@@" and ":**" give an error message when no register was used before.
- The search pattern "[]-`]" matches ']', '^', '_' and '`'.
- Autoindent for ":insert" is using the line below the insert.
- Autoindent for ":change" is using the first changed line.
- Editing Ex command lines is not done in cooked mode, because CTRL-D and
  CTRL-T cannot be handled then.
- In Ex mode, "1,3" prints three lines.  "%" prints all lines.
- In Ex mode "undo" would undo all changes since Ex mode was started.
- Implemented the 'prompt' option.


Debugger support					*new-debug-support*
----------------

The 'balloonexpr' option has been added.  This is a generic way to implement
balloon functionality.  You can use it to show info for the word under the
mouse pointer.


Remote file explorer					*new-netrw-explore*
--------------------

The netrw plugin now also supports viewing a directory, when "scp://" is used.
Deleting and renaming files is possible.

To avoid duplicating a lot of code, the previous file explorer plugin has been
integrated in the netrw plugin.  This means browsing local and remote files
works the same way.

":browse edit" and ":browse split" use the netrw plugin when it's available
and a GUI dialog is not possible.

The netrw plugin is maintained by Charles Campbell.

New Syntax/Indent/FTplugin files: ~

MuPAD source syntax, indent and ftplugin. (Dave Silvia)

Implemented b:undo_indent to undo indent settings when setting 'filetype' to a
different value.


New Keymaps: ~

Sinhala (Sri Lanka) (Harshula Jayasuriya)


New message translations: ~

The Ukranian messages are now also available in cp1251.

Irish message translations. (Kevin Patrick Scannell)

Vietnamese message translations and menu. (Phan Vinh Thinh)


Others: ~

Mac: Add the selection type to the clipboard, so that Block, line and
character selections can be used between two Vims. (Eckehard Berns)
Also fixes the problem that setting 'clipboard' to "unnamed" breaks using
"yyp".

Mac: GUI font selector. (Peter "Rain Dog" Cucka)

Mac: support for multi-byte characters. (Da Woon Jung)

GUI font selector for Motif. (Marcin Dalecki)

Nicer toolbar buttons for Motif. (Marcin Dalecki)

Mnemonics for the Motif find/replace dialog. (Marcin Dalecki)

Mac: better integration with Xcode.  Post a fake mouse-up event after the odoc
event and the drag receive handler to work around a stall after Vim loads a
file.  Fixed an off-by-one line number error. (Da Woon Jung)

Added the t_SI and t_EI escape sequences for starting and ending Insert mode.
To be used to set the cursor shape to a bar or a block.  No default values,
they are not supported by termcap/terminfo.

Autocommands can be defined local to a buffer.  This means they will also work
when the buffer does not have a name or no specific name.  See
|autocmd-buflocal|.  (Yakov Lerner)

For xterm most combinations of modifiers with function keys are recognized.
|xterm-modifier-keys|

When 'verbose' is set the output of ":highlight" will show where a highlight
item was last set.
When 'verbose' is set the output of the ":map", ":abbreviate", ":command",
":function" and ":autocmd" commands will show where it was last defined.
(Yegappan Lakshmanan)

==============================================================================
IMPROVEMENTS						*improvements-7*

":helpgrep" accepts a language specifier after the pattern: "pat@it".

Move the help for printing to a separate help file.  It's quite a lot now.

The pattern matching code was changed from a recursive function to an
iterative mechanism.  This avoids out-of-stack errors.  State is stored in
allocated memory, running out of memory can always be detected.  Allows
matching more complex things, but Vim may seem to hang while doing that.

":breakadd here" and ":breakdel here" can be used to set or delete a
breakpoint at the cursor.

The tutor was updated to make it simpler to use and added text to explain a
few more important commands.  Used ideas from Gabriel Zachmann.

Unix: When libcall() fails obtain an error message with dlerror() and display
it. (Johannes Zellner)

Added "nbsp" in 'listchars'. (David Blanchet)

Added the "acwrite" value for the 'buftype' option.  This is for a buffer that
doesn not have a name that refers to a file and is written with BufWriteCmd
autocommands.

For lisp indenting and matching parenthesis: (Sergey Khorev)
- square brackets are recognized properly
- #\(, #\), #\[ and #\] are recognized as character literals
- Lisp line comments (delimited by semicolon) are recognized

Added the "count" argument to match(), matchend() and matchstr(). (Ilya Sher)

winnr() takes an optional "$" and "#" arguments.  (Nikolai Weibull, Yegappan
Lakshmanan)

Added 'n' flag to search(): don't move the cursor. (Nikolai Weibull)

When uncompressing fails in the gzip plugin, give an error message but don't
delete the raw text.  Helps if the file has a .gz extension but is not
actually compressed. (Andrew Pimlott)

When C, C++ or IDL syntax is used, may additionally load doxygen syntax.
Also support setting the filetype to "cdoxygen" for C plus doxygen syntax.
(Michael Geddes)

The ":registers" command now displays multi-byte characters properly.

VMS: In the usage message mention that a slash can be used to make a flag
upper case.  Add color support to the builtin vt320 terminal codes.
(Zoltan Arpadffy)

For the '%' item in 'viminfo', allow a number to set a maximum for the number
of buffers.

The 'statusline' option can be local to the window, so that each window can
have a different value.  (partly by Yegappan Lakshmanan)

When a file looks like a shell script, check for an "exec" command that starts
the tcl interpreter. (suggested by Alexios Zavras)

Support conversion between utf-8 and latin9 (iso-8859-15) internally, so that
digraphs still work when iconv is not available.

When a session file is loaded while editing an unnamed, empty buffer that
buffer is wiped out.  Avoids that there is an unused buffer in the buffer
list.

Win32: When libintl.dll supports bind_textdomain_codeset(), use it.
(NAKADAIRA Yukihiro)

When foldtext() finds no text after removing the comment leader, use the
second line of the fold.  Helps for C-style /* */ comments where the first
line is just "/*".

When editing the same file from two systems (e.g., Unix and MS-Windows) there
mostly was no warning for an existing swap file, because the name of the
edited file differs (e.g., y:\dir\file vs /home/me/dir/file).  Added a flag to
the swap file to indicate it is in the same directory as the edited file.  The
used path then doesn't matter and the check for editing the same file is much
more reliable.

Client-server communication now supports 'encoding'.  When setting 'encoding'
in a Vim server to "utf-8", and using "vim --remote fname" in a console,
"fname" is converted from the console encoding to utf-8.  Also allows Vims
with different 'encoding' settings to exchange messages.

Internal: Changed ga_room into ga_maxlen, so that it doesn't need to be
incremented/decremented each time.

Included a few improvements for Motif from Marcin Dalecki.  Draw label
contents ourselves to make them handle fonts in a way configurable by Vim and
a bit less dependent on the X11 font management.

When a register is empty it is not stored in the viminfo file.

Removed the tcltags script, it's obsolete.

":redir @*>>" and ":redir @+>>" append to the clipboard.  Better check for
invalid characters after the register name. |:redir|

":redir => variable" and ":redir =>> variable" write or append to a variable.
(Yegappan Lakshmanan) |:redir|

":redir @{a-z}>>" appends to register a to z. (Yegappan Lakshmanan)

The 'verbosefile' option can be used to log messages in a file.  Verbose
messages are not displayed then.  The "-V{filename}" argument can be used to
log startup messages.

":let g:" lists global variables.
":let b:" lists buffer-local variables.
":let w:" lists window-local variables.
":let v:" lists Vim variables.

The stridx() and strridx() functions take a third argument, where to start
searching.  (Yegappan Lakshmanan)

The getreg() function takes an extra argument to be able to get the expression
for the '=' register instead of the result of evaluating it.

The setline() function can take a List argument to set multiple lines.  When
the line number is just below the last line the line is appended.

g CTRL-G also shows the number of characters if it differs from the number of
bytes.

Completion for ":debug" and entering an expression for the '=' register.  Skip
":" between range and command name. (Peter winters)

CTRL-Q in Insert mode now works like CTRL-V by default.  Previously it was
ignored.

When "beep" is included in 'debug' a function or script that causes a beep
will result in a message with the source of the error.

When completing buffer names, match with "\(^\|[\/]\)" instead of "^", so that
":buf stor<Tab>" finds both "include/storage.h" and "storage/main.c".

To count items (pattern matches) without changing the buffer the 'n' flag has
been added to |:substitute|.  See |count-items|.

The "screen.linux" $TERM name is recognized to set the default for
'background' to "dark". (Ciaran McCreesh)  Also for "cygwin".

The |FileChangedShell| autocommand event can now use the |v:fcs_reason|
variable that specifies what triggered the event.  |v:fcs_choice| can be used
to reload the buffer or ask the user what to do.

Not all modifiers were recognized for xterm function keys.  Added the
possibility in term codes to end in ";*X" or "O*X", where X is any character
and the * stands for the modifier code.
Added the <xUp>, <xDown>, <xLeft> and <xRight> keys, to be able to recognize
the two forms that xterm can send their codes in and still handle all possible
modifiers.

getwinvar() now also works to obtain a buffer-local option from the specified
window.

Added the "%s" item to 'errorformat'. (Yegappan Lakshmanan)

GTK GUI: use the GTK file dialog when it's available.  Mix from patches by
Grahame Bowland and Evan Webb.

Added ":scriptnames" to bugreport.vim, so that we can see what plugins were
used.

Win32: If the user changes the setting for the number of lines a scroll wheel
click scrolls it is now used immediately.  Previously Vim would need to be
restarted.

When using @= in an expression the value is expression @= contains.  ":let @=
= value" can be used to set the register contents.

A ! can be added to ":popup" to have the popup menu appear at the mouse
pointer position instead of the text cursor.

The table with encodings has been expanded with many MS-Windows codepages,
such as cp1250 and cp737, so that these can also be used on Unix without
prepending "8bit-".
When an encoding name starts with "microsoft-cp" ignore the "microsoft-" part.

Added the "customlist" completion argument to a user-defined command.  The
user-defined completion function should return the completion candidates as a
Vim List and the returned results are not filtered by Vim. (Yegappan
Lakshmanan)

Win32: Balloons can have multiple lines if common controls supports it.
(Sergey Khorev)

The 's' flag is added to the search() and searchpair() function to set the
' mark if the cursor is moved. (Yegappan Lakshmanan)

For 'errorformat' it was not possible to have a file name that contains the
character that follows after "%f".  For example, in "%f:%l:%m" the file name
could not contain ":".  Now include the first ":" where the rest of the
pattern matches.  In the example a ":" not followed by a line number is
included in the file name. (suggested by Emanuele Giaquinta)

For command-line completion the matches for various types of arguments are now
sorted: user commands, variables, syntax names, etc.

When no locale is set, thus using the "C" locale, Vim will work with latin1
characters, using it's own isupper()/toupper()/etc. functions.

When using an rxvt terminal emulator guess the value of 'background' using the
COLORFGBG environment variable. (Ciaran McCreesh)

Also support t_SI and t_EI on Unix with normal features. (Ciaran McCreesh)

==============================================================================
COMPILE TIME CHANGES					*compile-changes-7*

Dropped the support for the BeOS and Amiga GUI.  They were not maintained and
probably didn't work.  If you want to work on this: get the Vim 6.x version
and merge it back in.

Mac: "make" now creates the Vim.app directory and "make install" copies it to
its final destination. (Raf)

Mac: Made it possible to compile with Motif, Athena or GTK without tricks and
still being able to use the MacRoman conversion.  Added the os_mac_conv.c
file.

When running the tests and one of them fails to produce "test.out" the
following tests are still executed.  This helps when running out of memory.

When compiling with EXITFREE defined and the ccmalloc library it is possible
to detect memory leaks.  Some memory will always reported as leaked, such as
allocated by X11 library functions and the memory allocated in alloc_cmdbuff()
to store the ":quit" command.

Moved the code for printing to src/hardcopy.c.

Moved some code from main() to separate functions to make it easier to see
what is being done.  Use a structure to avoid a lot of arguments to the
functions.

Moved unix_expandpath() to misc1.c, so that it can also be used by os_mac.c
without copying the code.

Mac: When running "make install" the runtime files are installed as for Unix.
Avoids that too many files are copied.  When running "make" a link to the
runtime files is created to avoid a recursive copy that takes much time.

==============================================================================
BUG FIXES						*bug-fixes-7*

When using PostScript printing on MS-DOS the default 'printexpr' used "lpr"
instead of "copy".  When 'printdevice' was empty the copy command did not
work.  Use "LPT1" then.

The GTK font dialog uses a font size zero when the font name doesn't include a
size.  Use a default size of 10.

This example in the documentation didn't work:
    :e `=foo . ".c" `
Skip over the expression in `=expr` when looking for comments, |, % and #.

When ":helpgrep" doesn't find anything there is no error message.

"L" and "H" did not take closed folds into account.

Win32: The "-P title" argument stopped at the first title that matched, even
when it doesn't support MDI.

Mac GUI: CTRL-^ and CTRL-@ did not work.

"2daw" on "word." at the end of a line didn't include the preceding white
space.

Win32: Using FindExecutable() doesn't work to find a program.  Use
SearchPath() instead.  For executable() use $PATHEXT when the program searched
for doesn't have an extension.

When 'virtualedit' is set, moving the cursor up after appending a character
may move it to a different column.  Was caused by auto-formatting moving the
cursor and not putting it back where it was.

When indent was added automatically and then moving the cursor, the indent was
not deleted (like when pressing ESC).  The "I" flag in 'cpoptions' can be used
to make it work the old way.

When opening a command-line window, 'textwidth' gets set to 78 by the Vim
filetype plugin.  Reset 'textwidth' to 0 to avoid lines are broken.

After using cursor(line, col) moving up/down doesn't keep the same column.

Win32: Borland C before 5.5 requires using ".u." for LowPart and HighPart
fields. (Walter Briscoe)

On Sinix SYS_NMLN isn't always defined.  Define it ourselves. (Cristiano De
Michele)

Printing with PostScript may keep the printer waiting for more.  Append a
CTRL-D to the printer output. (Mike Williams)

When converting a string with a hex or octal number the leading '-' was
ignored.  ":echo '-05' + 0" resulted in 5 instead of -5.

Using "@:" to repeat a command line didn't work when it contains control
characters.  Also remove "'<,'>" when in Visual mode to avoid that it appears
twice.

When using file completion for a user command, it would not expand environment
variables like for a regular command with a file argument.

'cindent': When the argument of a #define looks like a C++ class the next line
is indented too much.

When 'comments' includes multi-byte characters inserting the middle part and
alignment may go wrong.  'cindent' also suffers from this for right-aligned
items.

Win32: when 'encoding' is set to "utf-8" getenv() still returns strings in the
active codepage.  Convert to utf-8.  Also for $HOME.

The default for 'helplang' was "zh" for both "zh_cn" and "zh_tw".  Now use
"cn" or "tw" as intended.

When 'bin' is set and 'eol' is not set then line2byte() added the line break
after the last line while it's not there.

Using foldlevel() in a WinEnter autocommand may not work.  Noticed when
resizing the GUI shell upon startup.

Python: Using buffer.append(f.readlines()) didn't work.  Allow appending a
string with a trailing newline.  The newline is ignored.

When using the ":saveas f2" command for buffer "f1", the Buffers menu would
contain "f2" twice, one of them leading to "f1".  Also trigger the BufFilePre
and BufFilePost events for the alternate buffer that gets the old name.

strridx() did not work well when the needle is empty. (Ciaran McCreesh)

GTK: Avoid a potential hang in gui_mch_wait_for_chars() when input arrives
just before it is invoked

VMS: Occasionally CR characters were inserted in the file.  Expansion of
environment variables was not correct. (Zoltan Arpadffy)

UTF-8: When 'delcombine' is set "dw" only deleted the last combining character
from the first character of the word.

When using ":sball" in an autocommand only the filetype in one buffer was
detected.  Reset did_filetype in enter_buffer().

When using ":argdo" and the window already was at the first argument index,
but not actually editing it, the current buffer would be used instead.

When ":next dir/*" includes many matches, adding the names to the argument
list may take an awful lot of time and can't be interrupted.  Allow
interrupting this.

When editing a file that was already loaded in a buffer, modelines were not
used.  Now window-local options in the modeline are set.  Buffer-local options
and global options remain unmodified.

Win32: When 'encoding' is set to "utf-8" in the vimrc file, files from the
command line with non-ASCII characters are not used correctly.  Recode the
file names when 'encoding' is set, using the Unicode command line.

Win32 console: When the default for 'encoding' ends up to be "latin1", the
default value of 'isprint' was wrong.

When an error message is given while waiting for a character (e.g., when an
xterm reports the number of colors), the hit-enter prompt overwrote the last
line.  Don't reset msg_didout in normal_cmd() for K_IGNORE.

Mac GUI: Shift-Tab didn't work.

When defining tooltip text, don't translate terminal codes, since it's not
going to be used like a command.

GTK 2: Check the tooltip text for valid utf-8 characters to avoid getting a
GTK error.  Invalid characters may appear when 'encoding' is changed.

GTK 2: Add a safety check for invalid utf-8 sequences, they can crash pango.

Win32: When 'encoding' is changed while starting up, use the Unicode command
line to convert the file arguments to 'encoding'.  Both for the GUI and the
console version.

Win32 GUI: latin9 text (iso-8859-15) was not displayed correctly, because
there is no codepage for latin9.  Do our own conversion from latin9 to UCS2.

When two versions of GTK+ 2 are installed it was possible to use the header
files from one and the library from the other.  Use GTK_LIBDIR to put the
directory for the library early in the link flags.

With the GUI find/replace dialog a replace only worked if the pattern was
literal text.  Now it works for any pattern.

When 'equalalways' is set and 'eadirection' is "hor", ":quit" would still
cause equalizing window heights in the vertical direction.

When ":emenu" is used in a startup script the command was put in the typeahead
buffer, causing a prompt for the crypt key to be messed up.

Mac OS/X: The default for 'isprint' included characters 128-160, causes
problems for Terminal.app.

When a syntax item with "containedin" is used, it may match in the start or
end of a region with a matchgroup, while this doesn't happen for a "contains"
argument.

When a transparent syntax items matches in another item where the highlighting
has already stopped (because of a he= argument), the highlighting would come
back.

When cscope is used to set the quickfix error list, it didn't get set if there
was only one match. (Sergey Khorev)

When 'confirm' is set and using ":bdel" in a modified buffer, then selecting
"cancel", would still give an error message.

The PopUp menu items that started Visual mode didn't work when not in Normal
mode.  Switching between selecting a word and a line was not possible.

Win32: The keypad decimal point always resulted in a '.', while on some
keyboards it's a ','.  Use MapVirtualKey(VK_DECIMAL, 2).

Removed unused function DisplayCompStringOpaque() from gui_w32.c

In Visual mode there is not always an indication whether the line break is
selected or not.  Highlight the character after the line when the line break
is included, e.g., after "v$o".

GTK: The <F10> key can't be mapped, it selects the menu.  Disable that with a
GTK setting and do select the menu when <F10> isn't mapped. (David Necas)

After "Y" '[ and '] were not at start/end of the yanked text.

When a telnet connection is dropped Vim preserves files and exits.  While
doing that a SIGHUP may arrive and disturbe us, thus ignore it. (Scott
Anderson)  Also postpone SIGHUP, SIGQUIT and SIGTERM until it's safe to
handle.  Added handle_signal().

When using "set laststatus=2 cmdheight=2" in the .gvimrc you may only get one
line for the cmdline. (Christian Robinson)  Invoke command_height() after the
GUI has started up.

When completing a file name on the command line backslashes are required for
white space.  Was only done for a space, not for a Tab.

When configure could not find a terminal library, compiling continued for a
long time before reporting the problem.  Added a configure check for tgetent()
being found in a library.

When the cursor is on the first char of the last line a ":g/pat/s///" command
may cause the cursor to be displayed below the text.

Win32: Editing a file with non-ASCII characters doesn't work when 'encoding'
is "utf-8".  use _wfullpath() instead of _fullpath(). (Yu-sung Moon)

When recovering the 'fileformat' and 'fileencoding' were taken from the
original file instead of from the swapfile.  When the file didn't exist, was
empty or the option was changed (e.g., with ":e ++fenc=cp123 file") it could
be wrong.  Now store 'fileformat' and 'fileencoding' in the swapfile and use
the values when recovering.

":bufdo g/something/p" overwrites each last printed text line with the file
message for the next buffer.  Temporarily clear 'shortmess' to avoid that.

Win32: Cannot edit a file starting with # with --remote.  Do escape % and #
when building the ":drop" command.

A comment or | just after a expresion-backtick argument was not recognized.
E.g. in :e `="foo"`"comment.

"(" does not stop at an empty sentence (single dot and white space) while ")"
does.  Also breaks "das" on that dot.

When doing "yy" with the cursor on a TAB the ruler could be wrong and "k"
moved the cursor to another column.

When 'commentstring' is '"%s' and there is a double quote in the line a double
quote before the fold marker isn't removed in the text displayed for a  closed
fold.

In Visual mode, when 'bin' and 'eol' set, g CTRL-G counted the last line
break, resulting in "selected 202 of 201 bytes".

Motif: fonts were not used for dialog components. (Marcin Dalecki)

Motif: After using a toolbar button the keyboard focus would be on the toolbar
(Lesstif problem). (Marcin Dalecki)

When using "y<C-V>`x" where mark x is in the first column, the last line was
not included.

Not all test scripts work properly on MS-Windows when checked out from CVS.
Use a Vim command to fix all fileformats to dos before executing the tests.

When using ":new" and the file fits in the window, lines could still be above
the window.  Now remove empty lines instead of keeping the relative position.

Cmdline completion didn't work after ":let var1 var<Tab>".

When using ":startinsert" or ":startreplace" when already in Insert mode
(possible when using CTRL-R =), pressing Esc would directly restart Insert
mode. (Peter Winters)

"2daw" didn't work at end of file if the last word is a single character.

Completion for ":next a'<Tab>" put a backslash before single quote, but it was
not removed when editing a file.  Now halve backslashes in save_patterns().
Also fix expanding a file name with the shell that contains "\'".

When doing "1,6d|put" only "fewer lines" was reported.  Now a following "more
lines" overwrites the message.

Configure could not handle "-Dfoo=long\ long" in the TCL config output.

When searching backwards, using a pattern that matches a newline and uses \zs
after that, didn't find a match.  Could also get a hang or end up in the right
column in the wrong line.

When $LANG is "sl" for slovenian, the slovak menu was used, since "slovak"
starts with "sl".

When 'paste' is set in the GUI the Paste toolbar button doesn't work.  Clear
'paste' when starting the GUI.

A message about a wrong viminfo line included the trailing NL.

When 'paste' is set in the GUI the toolbar button doesn't work in Insert mode.
Use ":exe" in menu.vim to avoid duplicating the commands, instead of using a
mapping.

Treat "mlterm" as an xterm-like terminal. (Seiichi Sato)

":z.4" and ":z=4" didn't work Vi compatible.

When sourcing a file, editing it and sourcing it again, it could appear twice
in ":scriptnames" and get a new <SID>, because the inode has changed.

When $SHELL is set but empty the 'shell' option would be empty.  Don't use an
empty $SHELL value.

A command "w! file" in .vimrc or $EXINIT didn't work.  Now it writes an empty
file.

When a CTRL-F command at the end of the file failed, the cursor was still
moved to the start of the line.  Now it remains where it is.

When using ":s" or "&" to repeat the last substitute and "$" was used to put
the cursor in the last column, put the cursor in the last column again.  This
is Vi compatible.

Vim is not fully POSIX compliant but sticks with traditional Vi behavior.
Added a few flags in 'cpoptions' to behave the POSIX way when wanted.  The
$VIM_POSIX environment variable is checked to set the default.

Appending to a register didn't insert a line break like Vi.  Added the '>'
flag to 'cpoptions' for this.

Using "I" in a line with only blanks appended to the line.  This is not Vi
compatible.  Added the 'H' flag in 'coptions' for this.

When joining multiple lines the cursor would be at the last joint, but Vi
leaves it at the position where "J" would put it.  Added the 'q' flag in
'cpoptions' for this.

Autoindent didn't work for ":insert" and ":append".

Using ":append" in an empty buffer kept the dummy line.  Now it's deleted to
be Vi compatible.

When reading commands from a file and stdout goes to a terminal, would still
request the xterm version.  Vim can't read it, thus the output went to the
shell and caused trouble there.

When redirecting to a register with an invalid name the redirection would
still be done (after an error message).  Now reset "redir_reg". (Yegappan
Lakshmanan)

It was not possible to use a NL after a backslash in Ex mode.  This is
sometimes used to feed multiple lines to a shell command.

When 'cmdheight' is set to 2 in .vimrc and the GUI uses the number of lines
from the terminal we actually get 3 lines for the cmdline in gvim.

When setting $HOME allocated memory would leak.

Win32: bold characters may sometimes write in another character cell.  Use
unicodepdy[] as for UTF-8. (Taro Muraoka)

":w fname" didn't work for files with 'buftype' set to "nofile".

The method used to locate user commands for completion differed from when they
are executed.  Abiguous command names were not completed properly.

Incremental search may cause a crash when there is a custom statusline that
indirectly invokes ":normal".

Diff mode failed when $DIFF_OPTIONS was set in the environment.  Unset it
before invoking "diff".

Completion didn't work after ":argdo", ":windo" and ":bufdo".  Also for ":set
&l:opt" and ":set &g:opt". (Peter Winters)

When setting 'ttymouse' to "dec" in an xterm that supports the DEC mouse
locator it doesn't work.  Now switch off the mouse before selecting another
mouse model.

When the CursorHold event is triggered and the commands peek for typed
characters the typeahead buffer may be messed up, e.g., when a mouse-up event
is received.  Avoid invoking the autocommands from the function waiting for a
character, let it put K_CURSORHOLD in the input buffer.

Removed the "COUNT" flag from ":argadd", to avoid ":argadd 1*" to be used like
":1argadd *".  Same for ":argdelete" and ":argedit".

Avoid that $LANG is used for the menus when LC_MESSAGES is "en_US".

Added backslashes before dashes in the vim.1 manual page to make the appear as
real dashes. (Pierr Habouzit)

Where "gq" left the cursor depended on the value of 'formatprg'.  Now "gq"
always leaves the cursor at the last line of the formatted text.

When editing a compressed file, such as "changelog.Debian.gz" file, filetype
detection may try to check the contents of the file while it's still
compressed.  Skip setting 'filetype' for compressed files until they have been
decompressed.  Required for patterns that end in a "*".

Starting with an argument "+cmd" or "-S script" causes the cursor the be moved
to the first line.  That breaks a BufReadPost autocommand that uses g`".
Don't move the cursor if it's somewhere past the first line.

"gg=G" while 'modifiable' is off was uninterruptable.

When 'encoding' is "sjis" inserting CTRL-V u d800 a few times causes a crash.
Don't insert a DBCS character with a NUL second byte.

In Insert mode CTRL-O <Home> didn't move the cursor.  Made "ins_at_eol" global
and reset it in nv_home().

Wildcard expansion failed: ":w /tmp/$$.`echo test`".  Don't put quotes around
spaces inside backticks.

After this sequence of commands: Y V p gv: the wrong line is selected.  Now
let "gv" select the text that was put, since the original text is deleted.
This should be the most useful thing to do.

":sleep 100u" sleeps for 100 seconds, not 100 usec as one might expect.  Give
an error message when the argument isn't recognized.

In gui_mch_draw_string() in gui_w32.c "unibuflen" wasn't static, resulting in
reallocating the buffer every time. (Alexei Alexandrov)

When using a Python "atexit" function it was not invoked when Vim exits.  Now
call Py_Finalize() for that. (Ugo Di Girolamo)
This breaks the thread stuff though, fixed by Ugo.

GTK GUI: using a .vimrc with "set cmdheight=2 lines=43" and ":split" right
after startup, the window layout is messed up. (Michael Schaap)  Added
win_new_shellsize() call in gui_init() to fix the topframe size.

Trick to get ...MOUSE_NM not used when there are vertical splits.  Now pass
column -1 for the left most window and add MOUSE_COLOFF for others.  Limits
mouse column to 10000.

searchpair() may hang when the end pattern has "\zs" at the end.  Check that
we find the same position again and advance one character.

When in diff mode and making a change that causes the "changed" highlighting
to disappear or reappear, it was still highlighted in another window.

When a ":next" command fails because the user selects "Abort" at the ATTENTION
prompt the argument index was advanced anyway.

When "~" is in 'iskeyword' the "gd" doesn't work, it's used for the previous
substitute pattern.  Put "\V" in the pattern to avoid that.

Use of sprintf() sometimes didn't check properly for buffer overflow.  Also
when using smsg().  Included code for snprintf() to avoid having to do size
checks where invoking them

":help \=<Tab>" didn't find "sub-replace-\=".  Wild menu for help tags didn't
show backslashes.  ":he :s\=" didn't work.

When reading an errorfile "~/" in a file name was not expanded.

GTK GUI: When adding a scrollbar (e.g. when using ":vsplit") in a script or
removing it the window size may change.  GTK sends us resize events when we
change the window size ourselves, but they may come at an unexpected moment.
Peek for a character to get any window resize events and fix 'columns' and
'lines' to undo this.

After deleting files from the argument list a session file generated with
":mksession" may contain invalid ":next" commands.

When 'shortmess' is empty and 'keymap' set to accents, in Insert mode CTRL-N
may cause the hit-enter prompt.  Typing 'a then didn't result in the accented
character.  Put the character typed at the prompt back in the typeahead buffer
so that mapping is done in the right mode.

setbufvar() and setwinvar() did not give error messages.

It was possible to set a variable with an illegal name, e.g. with setbufvar().
It was possible to define a function with illegal name, e.t. ":func F{-1}()"

CTRL-W F and "gf" didn't use the same method to get the file name.

When reporting a conversion error the line number of the last error could be
given.  Now report the first encountered error.

When using ":e ++enc=name file" and iconv() was used for conversion an error
caused a fallback to no conversion.  Now replace a character with '?' and
continue.

When opening a new buffer the local value of 'bomb' was not initialized from
the global value.

Win32: When using the "Edit with Vim" entry the file name was limited to about
200 characters.

When using command line completion for ":e *foo" and the file "+foo" exists
the resulting command ":e +foo" doesn't work.  Now insert a backslash: ":e
\+foo".

When the translation of "-- More --" was not 10 characters long the following
message would be in the wrong position.

At the more-prompt the last character in the last line wasn't drawn.

When deleting non-existing text while 'virtualedit' is set the '[ and '] marks
were not set.

Win32: Could not use "**/" in 'path', it had to be "**\".

The search pattern "\n" did not match at the end of the last line.

Searching for a pattern backwards, starting on the NUL at the end of the line
and 'encoding' is "utf-8" would match the pattern just before it incorrectly.
Affected searchpair('/\*', '', '\*/').

For the Find/Replace dialog it was possible that not finding the text resulted
in an error message while redrawing, which cleared the syntax highlighting
while it was being used, resulting in a crash.  Now don't clear syntax
highlighting, disable it with b_syn_error.

Win32: Combining UTF-8 characters were drawn on the previous character.
Could be noticed with a Thai font.

 vim:tw=78:ts=8:ft=help:norl:
