==============================================================================
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".
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" 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.
==============================================================================
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.
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
Italian (translated by Antonio Colombo). More languages will follow.
The Unix Makefile installs the Italian manual pages in .../man/it/man1/.
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
|errorlist()| function.
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.
- Implemented the 'prompt' option.

==============================================================================
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|
":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)
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.
