The output of the commands is captured in a new +" scratch window. For convenience, if the functions are invoked on a CVS +" output window, the original file is used for the cvs operation instead after +" the window is split. This is primarily useful when running CVSCommit and +" you need to see the changes made, so that CVSDiff is usable and shows up in +" another window. +" +" Command documentation {{{2 +" +" CVSAdd Performs "cvs add" on the current file. +" +" CVSAnnotate Performs "cvs annotate" on the current file. 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. +" Additionally, if the current buffer is a CVSAnnotate buffer +" already, the version number on the current line is used. +" +" If the 'CVSCommandAnnotateParent' variable is set to a +" non-zero value, the version previous to the one on the +" current line is used instead. This allows one to navigate +" back to examine the previous version of a line. +" +" CVSCommit[!] If called with arguments, this performs "cvs commit" using +" the arguments as 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. +" +" CVSDiff With no arguments, this performs "cvs diff" on the current +" file. With one argument, "cvs diff" is performed on the +" current file against the specified revision. With two +" arguments, cvs diff is performed between the specified +" revisions of the current file. This command uses the +" 'CVSCommandDiffOpt' variable to specify diff options. If +" that variable does not exist, then 'wbBc' is assumed. If +" you wish to have no options, then set it to the empty +" string. +" +" CVSEdit Performs "cvs edit" on the current file. +" +" CVSEditors Performs "cvs editors" on the current file. +" +" CVSGotoOriginal Returns the current window to the source buffer if the +" current buffer is a CVS output buffer. +" +" CVSLog Performs "cvs log" on the current file. +" +" CVSRevert Replaces the modified version of the current file with the +" most recent version from the repository. +" +" CVSReview Retrieves a particular version of the current file. If no +" argument is given, the most recent version of the file on +" the current branch is retrieved. The specified revision is +" retrieved into a new buffer. +" +" CVSStatus Performs "cvs status" on the current file. +" +" CVSUnedit Performs "cvs unedit" on the current file. +" +" CVSUpdate Performs "cvs update" on the current file. +" +" CVSVimDiff With no arguments, this prompts the user for a revision and +" then uses vimdiff to display the differences between the +" current file and the specified revision. 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 other 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. +" +" CVSWatch Takes an argument which must be one of [on|off|add|remove]. +" Performs "cvs watch" with the given argument on the current +" file. +" +" CVSWatchers Performs "cvs watchers" on the current file. +" +" CVSWatchAdd Alias for "CVSWatch add" +" +" CVSWatchOn Alias for "CVSWatch on" +" +" CVSWatchOff Alias for "CVSWatch off" +" +" CVSWatchRemove Alias for "CVSWatch remove" +" +" Mapping documentation: {{{2 +" +" By default, a mapping is defined for each command.

If not set, it defaults to 'edit'. +" +" CVSCommandEnableBufferSetup +" This variable, if set to a non-zero value, activates CVS buffer management +" mode. This mode means that two buffer variables, 'CVSRevision' and +" 'CVSBranch', are set if the file is CVS-controlled. This is useful for +" displaying version information in the status bar. +" +" CVSCommandInteractive +" This variable, if set to a non-zero value, causes appropriate functions (for +" the moment, only CVSReview) to query the user for a revision to use +" instead of the current revision if none is specified. +" +" CVSCommandNameMarker +" This variable, if set, configures the special attention-getting characters +" that appear on either side of the cvs buffer type in the buffer name. +" This has no effect unless 'CVSCommandNameResultBuffers' is set to a true +" value. If not set, it defaults to '_'. +" +" CVSCommandNameResultBuffers +" This variable, if set to a true value, causes the cvs result buffers to be +" named in the old way (' __'). If not set +" or set to a false value, the result buffer is nameless. +" +" CVSCommandSplit +" This variable controls the orientation of the various window splits that +" may occur (such as with CVSVimDiff, when using a CVS command on a CVS +" command buffer, or when the 'CVSCommandEdit' variable is set to 'split'. +" If set to 'horizontal', the resulting windows will be on stacked on top of +" one another.
