*hgcommand.txt* Mercurial vim integration #version#
HGCOMMAND REFERENCE MANUAL~
Author: Mathieu Clabaut <[email protected]>
Credits: Bob Hiestand <[email protected]>
Mercurial: http://mercurial.selenic.com/
Mercurial (noted Hg) is a fast, lightweight Source Control Management
system designed for efficient handling of very large distributed projects.
==============================================================================
1. Contents *hgcommand-contents*
Installation : |hgcommand-install|
HGCommand Intro : |hgcommand|
HGCommand Manual : |hgcommand-manual|
Customization : |hgcommand-customize|
Bugs : |hgcommand-bugs|
==============================================================================
2. HGCommand Installation *hgcommand-install*
In order to install the plugin, place the hgcommand.vim file into a plugin'
directory in your runtime path (please see |add-global-plugin| and
|'runtimepath'|.
HGCommand may be customized by setting variables, creating maps, and
specifying event handlers. Please see |hgcommand-customize| for more
details.
*hgcommand-auto-help*
The help file is automagically generated when the |hgcommand| script is
loaded for the first time.
==============================================================================
3. HGCommand Intro *hgcommand*
*hgcommand-intro*
The HGCommand plugin provides global ex commands for manipulating
HG-controlled source files. In general, each command operates on the
current buffer and accomplishes a separate hg function, such as update,
commit, log, and others (please see |hgcommand-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 |hgcommand-buffer-variables|).
The notion of "current file" means either the current buffer, or, in the
case of a directory buffer, the file on the current line within the buffer.
For convenience, any HGCommand invoked on a HGCommand 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 (though see |HGCommandInteractive| to prompt instead).
Each HGCommand 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
|hgcommand-mappings-override|.
The HGCommand plugin may be configured in several ways. For more details,
please see |hgcommand-customize|.
==============================================================================
4. HGCommand Manual *hgcommand-manual*
4.1 HGCommand commands *hgcommand-commands*
HGCommand defines the following commands:
|:HGAdd|
|:HGAnnotate|
|:HGCommit|
|:HGDiff|
|:HGGotoOriginal|
|:HGLog|
|:HGRevert|
|:HGReview|
|:HGStatus|
|:HGUpdate|
|:HGVimDiff|
:HGAdd *:HGAdd*
This command performs "hg add" on the current file. Please note, this does
not commit the newly-added file.
:HGAnnotate *:HGAnnotate*
This command performs "hg 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 HGAnnotate buffer
already, the version number on the current line is used.
If the |HGCommandAnnotateParent| 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.
The filetype of the HGCommand scratch buffer is set to 'HGAnnotate', to
take advantage of the bundled syntax file.
:HGCommit[!] *:HGCommit*
If called with arguments, this performs "hg commit" using the arguments as
the log message.
If '!' is used with no arguments, 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 :HGCommit (by default
<Leader>hgc) can be used in the log message buffer to immediately commit.
This is useful if the |HGCommandCommitOnWrite| variable is set to 0 to
disable the normal commit-on-write behavior.
:HGDiff *:HGDiff*
With no arguments, this performs "hg diff" on the current file against the
current repository version.
With one argument, "hg diff" is performed on the current file against the
specified revision.
With two arguments, hg diff is performed between the specified revisions of
the current file.
This command uses the 'HGCommandDiffOpt' 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.
:HGGotoOriginal *:HGGotoOriginal*
This command returns the current window to the source buffer, if the
current buffer is a HG command output buffer.
:HGGotoOriginal!
Like ":HGGotoOriginal" but also executes :bufwipeout on all HG command
output buffers for the source buffer.
:HGLog *:HGLog*
Performs "hg log" on the current file.
If an argument is given, it is passed as an argument to the "-r" option of
"hg log".
:HGRevert *:HGRevert*
Replaces the current file with the most recent version from the repository
in order to wipe out any undesired changes.
:HGReview *:HGReview*
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. Otherwise, the specified version is retrieved.
:HGStatus *:HGStatus*
Performs "hg status" on the current file.
:HGUpdate *:HGUpdate*
Performs "hg update" on the current file. 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.
:HGVimDiff *:HGVimDiff*
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.
4.2 Mappings *hgcommand-mappings*
By default, a mapping is defined for each command. These mappings execute
the default (no-argument) form of each command.
<Leader>hga HGAdd
<Leader>hgn HGAnnotate
<Leader>hgc HGCommit
<Leader>hgd HGDiff
<Leader>hgg HGGotoOriginal
<Leader>hgG HGGotoOriginal!
<Leader>hgl HGLog
<Leader>hgr HGReview
<Leader>hgs HGStatus
<Leader>hgu HGUpdate
<Leader>hgv HGVimDiff
*hgcommand-mappings-override*
The default mappings can be overriden 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).
For instance, to override the default mapping for :HGAdd to set it to
'\add', add the following to the vimrc: >
nmap \add <Plug>HGAdd
<
4.3 Automatic buffer variables *hgcommand-buffer-variables*
Several buffer variables are defined in each HGCommand result buffer.
These may be useful for additional customization in callbacks defined in
the event handlers (please see |hgcommand-events|).
The following variables are automatically defined:
b:hgOrigBuffNR *b:hgOrigBuffNR*
This variable is set to the buffer number of the source file.
b:hgcmd *b:hgcmd*
This variable is set to the name of the hg command that created the result
buffer.
==============================================================================
5. Configuration and customization *hgcommand-customize*
*hgcommand-config*
The HGCommand plugin can be configured in two ways: by setting
configuration variables (see |hgcommand-options|) or by defining HGCommand
event handlers (see |hgcommand-events|). Additionally, the HGCommand
plugin provides several option for naming the HG result buffers (see
|hgcommand-naming|) and supported a customized status line (see
|hgcommand-statusline| and |hgcommand-buffer-management|).
5.1 HGCommand configuration variables *hgcommand-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:
|HGCommandAnnotateParent|
|HGCommandCommitOnWrite|
|HGCommandHGExec|
|HGCommandDeleteOnHide|
|HGCommandDiffOpt|
|HGCommandDiffSplit|
|HGCommandEdit|
|HGCommandEnableBufferSetup|
|HGCommandInteractive|
|HGCommandNameMarker|
|HGCommandNameResultBuffers|
|HGCommandSplit|
HGCommandAnnotateParent *HGCommandAnnotateParent*
This variable, if set to a non-zero value, causes the zero-argument form of
HGAnnotate when invoked on a HGAnnotate buffer to go to the version
previous to that displayed on the current line. If not set, it defaults to
0.
HGCommandCommitOnWrite *HGCommandCommitOnWrite*
This variable, if set to a non-zero value, causes the pending hg commit to
take place immediately as soon as the log message buffer is written. If
set to zero, only the HGCommit mapping will cause the pending commit to
occur. If not set, it defaults to 1.
HGCommandHGExec *HGCommandHGExec*
This variable controls the executable used for all HG commands. If not
set, it defaults to "hg".
HGCommandDeleteOnHide *HGCommandDeleteOnHide*
This variable, if set to a non-zero value, causes the temporary HG result
buffers to automatically delete themselves when hidden.
HGCommandDiffOpt *HGCommandDiffOpt*
This variable, if set, determines the options passed to the diff command of
HG. If not set, it defaults to 'w'.
HGCommandDiffSplit *HGCommandDiffSplit*
This variable overrides the |HGCommandSplit| variable, but only for buffers
created with |:HGVimDiff|.
HGCommandEdit *HGCommandEdit*
This variable controls whether the original buffer is replaced ('edit') or
split ('split'). If not set, it defaults to 'edit'.
HGCommandEnableBufferSetup *HGCommandEnableBufferSetup*
This variable, if set to a non-zero value, activates HG buffer management
mode see (|hgcommand-buffer-management|). This mode means that three
buffer variables, 'HGRepository', 'HGRevision' and 'HGBranch', are set if
the file is HG-controlled. This is useful for displaying version
information in the status bar.
HGCommandInteractive *HGCommandInteractive*
This variable, if set to a non-zero value, causes appropriate commands (for
the moment, only |:HGReview|) to query the user for a revision to use
instead of the current revision if none is specified.
HGCommandNameMarker *HGCommandNameMarker*
This variable, if set, configures the special attention-getting characters
that appear on either side of the hg buffer type in the buffer name. This
has no effect unless |HGCommandNameResultBuffers| is set to a true value.
If not set, it defaults to '_'.
HGCommandNameResultBuffers *HGCommandNameResultBuffers*
This variable, if set to a true value, causes the hg result buffers to be
named in the old way ('<source file name> _<hg command>_'). If not set or
set to a false value, the result buffer is nameless.
HGCommandSplit *HGCommandSplit*
This variable controls the orientation of the various window splits that
may occur (such as with HGVimDiff, when using a HG command on a HG command
buffer, or when the |HGCommandEdit| variable is set to 'split'. 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 HGVimDiff windows.
5.2 HGCommand events *hgcommand-events*
For additional customization, HGCommand can trigger user-defined events.
Event handlers are provided by defining User event autocommands (see
|autocommand|, |User|) in the HGCommand 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 HGCommand scratch buffer: >
augroup HGCommand
au HGCommand User HGBufferCreated silent! nmap <unique> <buffer> q:
bwipeout<cr>
augroup END
<
The following hooks are available:
HGBufferCreated This event is fired just after a hg command result
buffer is created and filled with the result of a hg
command. It is executed within the context of the HG
command buffer. The HGCommand buffer variables may be
useful for handlers of this event (please see
|hgcommand-buffer-variables|).
HGBufferSetup This event is fired just after HG buffer setup occurs,
if enabled.
HGPluginInit This event is fired when the HGCommand plugin first
loads.
HGPluginFinish This event is fired just after the HGCommand plugin
loads.
HGVimDiffFinish This event is fired just after the HGVimDiff command
executes to allow customization of, for instance,
window placement and focus.
5.3 HGCommand buffer naming *hgcommand-naming*
By default, the buffers containing the result of HG commands are nameless
scratch buffers. It is intended that buffer variables of those buffers be
used to customize the statusline option so that the user may fully control
the display of result buffers.
If the old-style naming is desired, please enable the
|HGCommandNameResultBuffers| variable. Then, each result buffer will
receive a unique name that includes the source file name, the HG command,
and any extra data (such as revision numbers) that were part of the
command.
5.4 HGCommand status line support *hgcommand-statusline*
It is intended that the user will customize the |'statusline'| option to
include HG result buffer attributes. A sample function that may be used in
the |'statusline'| option is provided by the plugin, HGGetStatusLine(). In
order to use that function in the status line, do something like the
following: >
set statusline=%<%f\ %{HGGetStatusLine()}\ %h%m%r%=%l,%c%V\ %P
<
of which %{HGGetStatusLine()} is the relevant portion.
The sample HGGetStatusLine() function handles both HG result buffers and
HG-managed files if HGCommand buffer management is enabled (please see
|hgcommand-buffer-management|).
5.5 HGCommand buffer management *hgcommand-buffer-management*
The HGCommand plugin can operate in buffer management mode, which means
that it attempts to set two buffer variables ('HGRevision' and 'HGBranch')
upon entry into a buffer. This is rather slow because it means that 'hg
status' will be invoked at each entry into a buffer (during the |BufEnter|
autocommand).
This mode is enabled by default. In order to disable it, set the
|HGCommandEnableBufferSetup| variable to a false (zero) value. Enabling
this mode simply provides the buffer variables mentioned above. The user
must explicitly include those in the |'statusline'| option if they are to
appear in the status line (but see |hgcommand-statusline| for a simple way
to do that).

This splits the buffer vertically, puts an annotation on the left (minus
the header) with the width set to 40. An editable/normal copy is placed on
the right. The two versions are scroll locked so they move as one. and
wrapping is turned off so that the lines line up correctly. The advantages
are...
1) You get a versioning on the right.
2) You can still edit your own code.
3) Your own code still has syntax highlighting.

8. Known bugs *hgcommand-bugs*
Please let me know if you run across any.
HGVimDiff, 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.
==============================================================================
9. TODO *hgcommand-todo*
Integrate symlink tracking once HG will support them.
