2. vcscommand Installation *vcscommand-install*
The vcscommand plugin comprises five files: vcscommand.vim, vcssvn.vim,
vcscvs.vim, vcssvk.vim and vcscommand.txt (this file). In order to install
the plugin, place the vcscommand.vim, vcssvn.vim, vcssvk.vim, and vcscvs.vim
files into a plugin directory in your runtime path (please see
|add-global-plugin| and |'runtimepath'|.
This help file can be included in the VIM help system by copying it into a
'doc' directory in your runtime path and then executing the |:helptags|
command, specifying the full path of the 'doc' directory. Please see
|add-local-help| for more details.
vcscommand may be customized by setting variables, creating maps, and
specifying event handlers. Please see |vcscommand-customize| for more
details.
==============================================================================
3. vcscommand Intro *vcscommand*
*vcscommand-intro*
The vcscommand plugin provides global ex commands for manipulating
version-controlled source files, currently those controlled either by CVS or
Subversion. In general, each command operates on the current buffer and
accomplishes a separate source control function, such as update, commit, log,
and others (please see |vcscommand-commands| for a list of all available
commands). The results of each operation are displayed in a scratch buffer.
Several buffer variables are defined for those scratch buffers (please see
|vcscommand-buffer-variables|).
The notion of "current file" means either the current buffer, or, in the case
of a directory buffer (such as Explorer or netrw buffers), the directory (and
all subdirectories) represented by the the buffer.
For convenience, any vcscommand invoked on a vcscommand scratch buffer acts as
though it was invoked on the original file and splits the screen so that the
output appears in a new window.
Many of the commands accept revisions as arguments. By default, most operate
on the most recent revision on the current branch if no revision is specified.
Each vcscommand is mapped to a key sequence starting with the |<Leader>|
keystroke. The default mappings may be overridden by supplying different
mappings before the plugin is loaded, such as in the vimrc, in the standard
fashion for plugin mappings. For examples, please see
|vcscommand-mappings-override|.
The vcscommand plugin may be configured in several ways. For more details,
please see |vcscommand-customize|.
==============================================================================
4. vcscommand Manual *vcscommand-manual*
4.1 vcscommand commands *vcscommand-commands*
vcscommand defines the following commands:
|:VCSAdd|
|:VCSAnnotate|
|:VCSBlame|
|:VCSCommit|
|:VCSDelete|
|:VCSDiff|
|:VCSGotoOriginal|
|:VCSLog|
|:VCSRemove|
|:VCSRevert|
|:VCSReview|
|:VCSStatus|
|:VCSUpdate|
|:VCSVimDiff|
The following commands are specific to CVS files:
|:CVSEdit|
|:CVSEditors|
|:CVSUnedit|
|:CVSWatch|
|:CVSWatchAdd|
|:CVSWatchOn|
|:CVSWatchOff|
|:CVSWatchRemove|
|:CVSWatchers|
:VCSAdd *:VCSAdd*
This command adds the current file to source control. Please note, this does
not commit the newly-added file. All parameters to the command are passed to
the underlying VCS.
:VCSAnnotate[!] *:VCSAnnotate*
This command displays the current file with each line annotated with the
version in which it was most recently changed. If an argument is given, the
argument is used as a revision number to display. If not given an argument,
it uses the most recent version of the file (on the current branch, if under
CVS control). Additionally, if the current buffer is a VCSAnnotate buffer
already, the version number on the current line is used.
If '!' is used, the view of the annotated buffer is split so that the
annotation is in a separate window from the content, and each is highlighted
separately.
For CVS buffers, the 'VCSCommandCVSAnnotateParent' option, if set to non-zero,
will cause the above behavior to change. Instead of annotating the version on
the current line, the parent revision is used instead, crossing branches if
necessary.
With no arguments the cursor will jump to the line in the annotated buffer
corresponding to the current line in the source buffer.
:VCSBlame[!] *:VCSBlame*
Alias for |:VCSAnnotate|.
:VCSCommit[!] *:VCSCommit*
This command commits changes to the current file to source control.
If called with arguments, the arguments are the log message.
If '!' is used, an empty log message is committed.
If called with no arguments, this is a two-step command. The first step opens
a buffer to accept a log message. When that buffer is written, it is
automatically closed and the file is committed using the information from that
log message. The commit can be abandoned if the log message buffer is deleted
or wiped before being written.
Alternatively, the mapping that is used to invoke :VCSCommit (by default
|<Leader>|cc, please see |vcscommand-mappings|) can be used in the log message
buffer in Normal mode to immediately commit. This is useful if the
|VCSCommandCommitOnWrite| variable is set to 0 to disable the normal
commit-on-write behavior.
:VCSDelete *:VCSDelete*
Deletes the current file and removes it from source control. All parameters
to the command are passed to the underlying VCS.
:VCSDiff *:VCSDiff*
With no arguments, this displays the differences between the current file and
its parent version under source control in a new scratch buffer.
With one argument, the diff is performed on the current file against the
specified revision.
With two arguments, the diff is performed between the specified revisions of
the current file.
For CVS, this command uses the |VCSCommandCVSDiffOpt| variable to specify diff
options. If that variable does not exist, a plugin-specific default is used.
If you wish to have no options, then set it to the empty string.
For SVN, this command uses the |VCSCommandSVNDiffOpt| variable to specify diff
options. If that variable does not exist, the SVN default is used.
Additionally, |VCSCommandSVNDiffExt| can be used to select an external diff
application.
:VCSGotoOriginal *:VCSGotoOriginal*
This command jumps to the source buffer if the current buffer is a VCS scratch
buffer.
:VCSGotoOriginal!
Like ":VCSGotoOriginal" but also executes :bufwipeout on all VCS scrach
buffers associated with the original file.
:VCSInfo *:VCSInfo*
This command displays extended information about the current file in a new
scratch buffer.
:VCSLock *:VCSLock*
This command locks the current file in order to prevent other users from
concurrently modifying it. The exact semantics of this command depend on the
underlying VCS. This does nothing in CVS. All parameters are passed to the
underlying VCS.
:VCSLog *:VCSLog*
Displays the version history of the current file in a new scratch buffer. If
there is one parameter supplied, it is taken as as a revision parameters to be
passed through to the underlying VCS. Otherwise, all parameters are passed to
the underlying VCS.
:VCSRemove *:VCSRemove*
Alias for |:VCSDelete|.
:VCSRevert *:VCSRevert*
This command replaces the current file with the most recent version from the
repository in order to wipe out any undesired changes.
:VCSReview *:VCSReview*
Displays a particular version of the current file in a new scratch buffer. If
no argument is given, the most recent version of the file on the current
branch is retrieved.
:VCSStatus *:VCSStatus*
Displays versioning information about the current file in a new scratch
buffer. All parameters are passed to the underlying VCS.
:VCSUnlock *:VCSUnlock*
Unlocks the current file in order to allow other users from concurrently
modifying it. The exact semantics of this command depend on the underlying
VCS. All parameters are passed to the underlying VCS.
:VCSUpdate *:VCSUpdate*
Updates the current file with any relevant changes from the repository. This
intentionally does not automatically reload the current buffer, though vim
should prompt the user to do so if the underlying file is altered by this
command.
:VCSVimDiff *:VCSVimDiff*
Uses vimdiff to display differences between versions of the current file.
If no revision is specified, the most recent version of the file on the
current branch is used. With one argument, that argument is used as the
revision as above. With two arguments, the differences between the two
revisions is displayed using vimdiff.
With either zero or one argument, the original buffer is used to perform the
vimdiff. When the scratch buffer is closed, the original buffer will be
returned to normal mode.
Once vimdiff mode is started using the above methods, additional vimdiff
buffers may be added by passing a single version argument to the command.
There may be up to 4 vimdiff buffers total.
Using the 2-argument form of the command resets the vimdiff to only those 2
versions. Additionally, invoking the command on a different file will close
the previous vimdiff buffers.
:CVSEdit *:CVSEdit*
This command performs "cvs edit" on the current file. Yes, the output buffer
in this case is almost completely useless.
:CVSEditors *:CVSEditors*
This command performs "cvs edit" on the current file.
:CVSUnedit *:CVSUnedit*
Performs "cvs unedit" on the current file. Again, yes, the output buffer here
is basically useless.
:CVSWatch *:CVSWatch*
This command takes an argument which must be one of [on|off|add|remove]. The
command performs "cvs watch" with the given argument on the current file.
:CVSWatchAdd *:CVSWatchAdd*
This command is an alias for ":CVSWatch add"
:CVSWatchOn *:CVSWatchOn*
This command is an alias for ":CVSWatch on"
:CVSWatchOff *:CVSWatchOff*
This command is an alias for ":CVSWatch off"
:CVSWatchRemove *:CVSWatchRemove*
This command is an alias for ":CVSWatch remove"
:CVSWatchers *:CVSWatchers*
This command performs "cvs watchers" on the current file.
4.2 Mappings *vcscommand-mappings*
By default, a mapping is defined for each command. These mappings execute the
default (no-argument) form of each command.
|<Leader>|ca VCSAdd
|<Leader>|cn VCSAnnotate
|<Leader>|cN VCSAnnotate!
|<Leader>|cc VCSCommit
|<Leader>|cD VCSDelete
|<Leader>|cd VCSDiff
|<Leader>|cg VCSGotoOriginal
|<Leader>|cG VCSGotoOriginal!
|<Leader>|ci VCSInfo
|<Leader>|cl VCSLog
|<Leader>|cL VCSLock
|<Leader>|cr VCSReview
|<Leader>|cs VCSStatus
|<Leader>|cu VCSUpdate
|<Leader>|cU VCSUnlock
|<Leader>|cv VCSVimDiff
Only for CVS buffers:
|<Leader>|ce CVSEdit
|<Leader>|cE CVSEditors
|<Leader>|ct CVSUnedit
|<Leader>|cwv CVSWatchers
|<Leader>|cwa CVSWatchAdd
|<Leader>|cwn CVSWatchOn
|<Leader>|cwf CVSWatchOff
|<Leader>|cwf CVSWatchRemove
*vcscommand-mappings-override*
The default mappings can be overridden by user-provided instead by mapping to
<Plug>CommandName. This is especially useful when these mappings collide with
other existing mappings (vim will warn of this during plugin initialization,
but will not clobber the existing mappings).
There are three methods for controlling mapping:
First, maps can be overriden for individual commands. For instance, to
override the default mapping for :VCSAdd to set it to '\add', add the
following to the vimrc:
nmap \add <Plug>VCSAdd
Second, the default map prefix ('<Leader>c') can be overridden by defining the
|VCSCommandMapPrefix| variable.
Third, the entire set of default maps can be overridden by defining the
|VCSCommandMappings| variable.
4.3 Automatic buffer variables *vcscommand-buffer-variables*
Several buffer variables are defined in each vcscommand result buffer. These
may be useful for additional customization in callbacks defined in the event
handlers (please see |vcscommand-events|).
The following variables are automatically defined:
b:VCSCommandOriginalBuffer *b:VCSCommandOriginalBuffer*
This variable is set to the buffer number of the source file.
b:VCSCommandCommand *b:VCSCommandCommand*
This variable is set to the name of the vcscommand that created the result
buffer.
b:VCSCommandSourceFile *b:VCSCommandSourceFile*
This variable is set to the name of the original file under source control.
b:VCSCommandVCSType *b:VCSCommandVCSType*
This variable is set to the type of the source control. This variable is also
set on the original file itself.
==============================================================================
5. Configuration and customization *vcscommand-customize*
*vcscommand-config*
The vcscommand plugin can be configured in several ways: by setting
configuration variables (see |vcscommand-options|) or by defining vcscommand
event handlers (see |vcscommand-events|). Additionally, the vcscommand plugin
supports a customized status line (see |vcscommand-statusline| and
|vcscommand-buffer-management|).
5.1 vcscommand configuration variables *vcscommand-options*
Several variables affect the plugin's behavior. These variables are checked
at time of execution, and may be defined at the window, buffer, or global
level and are checked in that order of precedence.
The following variables are available:
|VCSCommandCommitOnWrite|
|VCSCommandCVSDiffOpt|
|VCSCommandCVSExec|
|VCSCommandDeleteOnHide|
|VCSCommandDiffSplit|
|VCSCommandDisableAll|
|VCSCommandDisableMappings|
|VCSCommandDisableExtensionMappings|
|VCSCommandDisableMenu|
|VCSCommandEdit|
|VCSCommandEnableBufferSetup|
|VCSCommandMappings|
|VCSCommandMapPrefix|
|VCSCommandMenuPriority|
|VCSCommandMenuRoot|
|VCSCommandResultBufferNameExtension|
|VCSCommandResultBufferNameFunction|
|VCSCommandSplit|
|VCSCommandSVKExec|
|VCSCommandSVNDiffExt|
|VCSCommandSVNDiffOpt|
|VCSCommandSVNExec|
|VCSCommandVCSTypeOverride|
|VCSCommandVCSTypePreference|
VCSCommandCommitOnWrite *VCSCommandCommitOnWrite*
This variable, if set to a non-zero value, causes the pending commit
to take place immediately as soon as the log message buffer is written.
If set to zero, only the VCSCommit mapping will cause the pending commit to
occur. If not set, it defaults to 1.
VCSCommandCVSExec *VCSCommandCVSExec*
This variable controls the executable used for all CVS commands If not set,
it defaults to "cvs".
VCSCommandDeleteOnHide *VCSCommandDeleteOnHide*
This variable, if set to a non-zero value, causes the temporary result buffers
to automatically delete themselves when hidden.
VCSCommandCVSDiffOpt *VCSCommandCVSDiffOpt*
This variable, if set, determines the options passed to the diff command of
CVS. If not set, it defaults to 'u'.
VCSCommandDiffSplit *VCSCommandDiffSplit*
This variable overrides the |VCSCommandSplit| variable, but only for buffers
created with |:VCSVimDiff|.
VCSCommandDisableAll *VCSCommandDisableAll*
This variable, if set, prevents the plugin or any extensions from loading at
all. This is useful when a single runtime distribution is used on multiple
systems with varying versions.
VCSCommandDisableMappings *VCSCommandDisableMappings*
This variable, if set to a non-zero value, prevents the default command
mappings from being set. This supercedes
|VCSCommandDisableExtensionMappings|.
VCSCommandDisableExtensionMappings *VCSCommandDisableExtensionMappings*
This variable, if set to a non-zero value, prevents the default command
mappings from being set for commands specific to an individual VCS.
VCSCommandEdit *VCSCommandEdit*
This variable controls whether the original buffer is replaced ('edit') or
split ('split'). If not set, it defaults to 'split'.
VCSCommandDisableMenu *VCSCommandDisableMenu*
This variable, if set to a non-zero value, prevents the default command menu
from being set.
VCSCommandEnableBufferSetup *VCSCommandEnableBufferSetup*
This variable, if set to a non-zero value, activates VCS buffer management
mode see (|vcscommand-buffer-management|). This mode means that the
'VCSCommandBufferInfo' variable is filled with version information if the file
is VCS-controlled. This is useful for displaying version information in the
status bar.
VCSCommandMappings *VCSCommandMappings*
This variable, if set, overrides the default mappings used for shortcuts. It
should be a List of 2-element Lists, each containing a shortcut and function
name pair. The value of the '|VCSCommandMapPrefix|' variable will be added to
each shortcut.
VCSCommandMapPrefix *VCSCommandMapPrefix*
This variable, if set, overrides the default mapping prefix ('<Leader>c').
This allows customization of the mapping space used by the vcscommand
shortcuts.
VCSCommandMenuPriority *VCSCommandMenuPriority*
This variable, if set, overrides the default menu priority '' (empty)
VCSCommandMenuRoot *VCSCommandMenuRoot*
This variable, if set, overrides the default menu root 'Plugin.VCS'
VCSCommandResultBufferNameExtension *VCSCommandResultBufferNameExtension*
This variable, if set to a non-blank value, is appended to the name of the VCS
command output buffers. For example, '.vcs'. Using this option may help
avoid problems caused by autocommands dependent on file extension.
VCSCommandResultBufferNameFunction *VCSCommandResultBufferNameFunction*
This variable, if set, specifies a custom function for naming VCS command
output buffers. This function is expected to return the new buffer name, and
will be passed the following arguments:
command - name of the VCS command being executed (such as 'Log' or
'Diff').
originalBuffer - buffer number of the source file.
vcsType - type of VCS controlling this file (such as 'CVS' or 'SVN').
statusText - extra text associated with the VCS action (such as version
numbers).
VCSCommandSplit *VCSCommandSplit*
This variable controls the orientation of the various window splits that
may occur.
If set to 'horizontal', the resulting windows will be on stacked on top of
one another. If set to 'vertical', the resulting windows will be
side-by-side. If not set, it defaults to 'horizontal' for all but
VCSVimDiff windows. VCSVimDiff windows default to the user's 'diffopt'
setting, if set, otherwise 'vertical'.
VCSCommandSVKExec *VCSCommandSVKExec*
This variable controls the executable used for all SVK commands If not set,
it defaults to "svk".
VCSCommandSVNDiffExt *VCSCommandSVNDiffExt*
This variable, if set, is passed to SVN via the --diff-cmd command to select
an external application for performing the diff.
VCSCommandSVNDiffOpt *VCSCommandSVNDiffOpt*
This variable, if set, determines the options passed with the '-x' parameter
to the SVN diff command. If not set, no options are passed.
VCSCommandSVNExec *VCSCommandSVNExec*
This variable controls the executable used for all SVN commands If not set,
it defaults to "svn".
VCSCommandVCSTypeOverride *VCSCommandVCSTypeOverride*
This variable allows the VCS type detection to be overridden on a path-by-path
basis. The value of this variable is expected to be a List of Lists. Each
item in the high-level List is a List containing two elements. The first
element is a regular expression that will be matched against the full file
name of a given buffer. If it matches, the second element will be used as the
VCS type.
VCSCommandVCSTypePreference *VCSCommandVCSTypePreference*
This variable allows the VCS type detection to be weighted towards a specific
VCS, in case more than one potential VCS is detected as useable. The format
of the variable is either a list or a space-separated string containing the
ordered-by-preference abbreviations of the preferred VCS types.
5.2 VCSCommand events *vcscommand-events*
For additional customization, vcscommand can trigger user-defined events.
Event handlers are provided by defining User event autocommands (see
|autocommand|, |User|) in the vcscommand group with patterns matching the
event name.
For instance, the following could be added to the vimrc to provide a 'q'
mapping to quit a vcscommand scratch buffer:
augroup VCSCommand
au User VCSBufferCreated silent! nmap <unique> <buffer> q :bwipeout<cr>
augroup END
The following hooks are available:
VCSBufferCreated This event is fired just after a vcscommand
result buffer is created and populated. It is
executed within the context of the vcscommand
buffer. The vcscommand buffer variables may
be useful for handlers of this event (please
see |vcscommand-buffer-variables|).
VCSBufferSetup This event is fired just after vcscommand buffer
setup occurs, if enabled.
VCSPluginInit This event is fired when the vcscommand plugin
first loads.
VCSPluginFinish This event is fired just after the vcscommand
plugin loads.
VCSVimDiffFinish This event is fired just after the VCSVimDiff
command executes to allow customization of,
for instance, window placement and focus.
Additionally, there is another hook which is used internally to handle loading
the multiple scripts in order. This hook should probably not be used by an
end user without a good idea of how it works. Among other things, any events
associated with this hook are cleared after they are executed (during
vcscommand.vim script initialization).
VCSLoadExtensions This event is fired just before the
VCSPluginFinish. It is used internally to
execute any commands from the VCS
implementation plugins that needs to be
deferred until the primary plugin is
initialized.
5.3 vcscommand buffer naming *vcscommand-naming*
vcscommand result buffers use the following naming convention:
[{VCS type} {VCS command} {Source file name}]
If additional buffers are created that would otherwise conflict, a
distinguishing number is added:
[{VCS type} {VCS command} {Source file name}] (1,2, etc)
5.4 vcscommand status line support *vcscommand-statusline*
It is intended that the user will customize the |'statusline'| option to
include vcscommand result buffer attributes. A sample function that may be
used in the |'statusline'| option is provided by the plugin,
VCSCommandGetStatusLine(). In order to use that function in the status line, do
something like the following:
set statusline=%<%f\ %{VCSCommandGetStatusLine()}\ %h%m%r%=%l,%c%V\ %P
of which %{VCSCommandGetStatusLine()} is the relevant portion.
The sample VCSCommandGetStatusLine() function handles both vcscommand result
buffers and VCS-managed files if vcscommand buffer management is enabled
(please see |vcscommand-buffer-management|).
5.5 vcscommand buffer management *vcscommand-buffer-management*
The vcscommand plugin can operate in buffer management mode, which means that
it attempts to set a buffer variable ('VCSCommandBufferInfo') upon entry into
a buffer. This is rather slow because it means that the VCS will be invoked
at each entry into a buffer (during the |BufEnter| autocommand).
This mode is disabled by default. In order to enable it, set the
|VCSCommandEnableBufferSetup| variable to a true (non-zero) value. Enabling
this mode simply provides the buffer variable mentioned above. The user must
explicitly include information from the variable in the |'statusline'| option
if they are to appear in the status line (but see |vcscommand-statusline| for
a simple way to do that).
The 'VCSCommandBufferInfo' variable is a list which contains, in order, the
revision of the current file, the latest revision of the file in the
repository, and (for CVS) the name of the branch. If those values cannot be
determined, the list is a single element: 'Unknown'.
==============================================================================
6. SSH "integration" *vcscommand-ssh*
The following instructions are intended for use in integrating the
vcscommand.vim plugin with an SSH-based CVS environment.
Familiarity with SSH and CVS are assumed.
These instructions assume that the intent is to have a message box pop up in
order to allow the user to enter a passphrase. If, instead, the user is
comfortable using certificate-based authentication, then only instructions
6.1.1 and 6.1.2 (and optionally 6.1.4) need to be followed; ssh should then
work transparently.
6.1 Environment settings *vcscommand-ssh-env*
6.1.1 CVSROOT should be set to something like:
:ext:user@host:/path_to_repository
6.1.2 CVS_RSH should be set to:
ssh
Together, those settings tell CVS to use ssh as the transport when
performing CVS calls.
6.1.3 SSH_ASKPASS should be set to the password-dialog program. In my case,
running gnome, it's set to:
/usr/libexec/openssh/gnome-ssh-askpass
This tells SSH how to get passwords if no input is available.
6.1.4 OPTIONAL. You may need to set SSH_SERVER to the location of the cvs
executable on the remote (server) machine.
6.2 CVS wrapper program *vcscommand-ssh-wrapper*
Now you need to convince SSH to use the password-dialog program. This means
you need to execute SSH (and therefore CVS) without standard input. The
following script is a simple perl wrapper that dissasociates the CVS command
from the current terminal. Specific steps to do this may vary from system to
system; the following example works for me on linux.
#!/usr/bin/perl -w
use strict;
use POSIX qw(setsid);
open STDIN, '/dev/null';
fork and do {wait; exit;};
setsid;
exec('cvs', @ARGV);
6.3 Configuring vcscommand.vim *vcscommand-ssh-config*
At this point, you should be able to use your wrapper script to invoke CVS with
various commands, and get the password dialog. All that's left is to make CVS
use your newly-created wrapper script.
6.3.1 Tell vcscommand.vim what CVS executable to use. The easiest way to do this
is globally, by putting the following in your .vimrc:
let VCSCommandCVSExec=/path/to/cvs/wrapper/script
6.4 Where to go from here *vcscommand-ssh-other*
The script given above works even when non-SSH CVS connections are used,
except possibly when interactively entering the message for CVS commit log
(depending on the editor you use... VIM works fine). Since the vcscommand.vim
plugin handles that message without a terminal, the wrapper script can be used
all the time.
This allows mixed-mode operation, where some work is done with SSH-based CVS
repositories, and others with pserver or local access.
It is possible, though beyond the scope of the plugin, to dynamically set the
CVS executable based on the CVSROOT for the file being edited. The user
events provided (such as VCSBufferCreated and VCSBufferSetup) can be used to
set a buffer-local value (b:VCSCommandCVSExec) to override the CVS executable
on a file-by-file basis. Alternatively, much the same can be done (less
automatically) by the various project-oriented plugins out there.
It is highly recommended for ease-of-use that certificates with no passphrase
or ssh-agent are employed so that the user is not given the password prompt
too often.
==============================================================================
7. Changes from cvscommand *cvscommand-changes*
1. Require Vim 7 in order to leverage several convenient features; also
because I wanted to play with Vim 7.
2. Renamed commands to start with 'VCS' instead of 'CVS'. The exceptions are
the 'CVSEdit' and 'CVSWatch' family of commands, which are specific to CVS.
3. Renamed options, events to start with 'VCSCommand'.
4. Removed option to jump to the parent version of the current line in an
annotated buffer, as opposed to the version on the current line. This made
little sense in the branching scheme used by subversion, where jumping to a
parent branch required finding a different location in the repository. It
didn't work consistently in CVS anyway.
5. Removed option to have nameless scratch buffers.
6. Changed default behavior of scratch buffers to split the window instead of
displaying in the current window. This may still be overridden using the
'VCSCommandEdit' option.
7. Split plugin into multiple plugins.
8. Added 'VCSLock' and 'VCSUnlock' commands. These are implemented for
subversion but not for CVS. These were not kept specific to subversion as they
seemed more general in nature and more likely to be supported by any future VCS
supported by this plugin.
9. Changed name of buffer variables set by commands.
'b:cvsOrigBuffNR' became 'b:VCSCommandOriginalBuffer'
'b:cvscmd' became 'b:VCSCommandCommand'
10. Added new automatic variables to command result buffers.
'b:VCSCommandSourceFile'

8. Known bugs *vcscommand-bugs*
Please let me know if you run across any.
CVSUnedit may, if a file is changed from the repository, provide prompt text
to determine whether the changes should be thrown away. Currently, that text
shows up in the CVS result buffer as information; there is no way for the user
to actually respond to the prompt and the CVS unedit command does nothing. If
this really bothers anyone, please let me know.
VCSVimDiff, when using the original (real) source buffer as one of the diff
buffers, uses some hacks to try to restore the state of the original buffer
when the scratch buffer containing the other version is destroyed. There may
still be bugs in here, depending on many configuration details.
