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 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). 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). ============================================================================== 9. Tips *hgcommand-tips* 9.1 Split window annotation, by Michael Anderson > :nmap <Leader>hgN :vs<CR><C-w>h<Leader>hgn:vertical res 40<CR> \ggdddd:set scb<CR>:set nowrap<CR><C-w>lgg:set scb<CR> \:set nowrap<CR> < 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. ============================================================================== === END_DOC """""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""" " v im:tw=78:ts=8:ft=help:norl: " vim600: set foldmethod=marker tabstop=8 shiftwidth=2 softtabstop=2 smartindent smarttab : "fileencoding=iso-8859-15
