28 " Section: Documentation {{{1
29 "
30 " Provides functions to invoke various source control commands on the current
31 " file (either the current buffer, or, in the case of an directory buffer, the
32 " directory and all subdirectories associated with the current buffer). The
33 " output of the commands is captured in a new scratch window.
34 "
35 " This plugin needs additional extension plugins, each specific to a source
36 " control system, to function. Several options include the name of the
37 " version control system in the option name. Such options use the placeholder
38 " text '{VCSType}', which would be replaced in actual usage with 'CVS' or
39 " 'SVN', for instance.
40 "
41 " Command documentation {{{2
42 "
43 " VCSAdd Adds the current file to source control.
44 "
45 " VCSAnnotate[!] Displays the current file with each line annotated with the
46 " version in which it was most recently changed. If an
47 " argument is given, the argument is used as a revision
48 " number to display. If not given an argument, it uses the
49 " most recent version of the file on the current branch.
50 " Additionally, if the current buffer is a VCSAnnotate buffer
51 " already, the version number on the current line is used.
52 "
53 " If '!' is used, the view of the annotated buffer is split
54 " so that the annotation is in a separate window from the
55 " content, and each is highlighted separately.
56 "
57 " VCSBlame Alias for 'VCSAnnotate'.
58 "
59 " VCSCommit[!] Commits changes to the current file to source control.
60 "
61 " If called with arguments, the arguments are the log message.
62 "
63 " If '!' is used, an empty log message is committed.
64 "
65 " If called with no arguments, this is a two-step command.
66 " The first step opens a buffer to accept a log message.
67 " When that buffer is written, it is automatically closed and
68 " the file is committed using the information from that log
69 " message. The commit can be abandoned if the log message
70 " buffer is deleted or wiped before being written.
71 "
72 " VCSDelete Deletes the current file and removes it from source control.
73 "
74 " VCSDiff With no arguments, this displays the differences between
75 " the current file and its parent version under source
76 " control in a new scratch buffer.
77 "
78 " With one argument, the diff is performed on the
79 " current file against the specified revision.
80 "
81 " With two arguments, the diff is performed between the
82 " specified revisions of the current file.
83 "
84 " This command uses the 'VCSCommand{VCSType}DiffOpt' variable
85 " to specify diff options. If that variable does not exist,
86 " a plugin-specific default is used. If you wish to have no
87 " options, then set it to the empty string.
88 "
89 " VCSGotoOriginal Jumps to the source buffer if the current buffer is a VCS
90 " scratch buffer. If VCSGotoOriginal[!] is used, remove all
91 " VCS scratch buffers associated with the original file.
92 "
93 " VCSInfo Displays extended information about the current file in a
94 " new scratch buffer.
95 "
96 " VCSLock Locks the current file in order to prevent other users from
97 " concurrently modifying it. The exact semantics of this
98 " command depend on the underlying VCS.
99 "
100 " VCSLog Displays the version history of the current file in a new
101 " scratch buffer.
102 "
103 " VCSRemove Alias for 'VCSDelete'.
104 "
105 " VCSRevert Replaces the modified version of the current file with the
106 " most recent version from the repository.
107 "
108 " VCSReview Displays a particular version of the current file in a new
109 " scratch buffer. If no argument is given, the most recent
110 " version of the file on the current branch is retrieved.
111 "
112 " VCSStatus Displays versioning information about the current file in a
113 " new scratch buffer.
114 "
115 " VCSUnlock Unlocks the current file in order to allow other users from
116 " concurrently modifying it. The exact semantics of this
117 " command depend on the underlying VCS.
118 "
119 " VCSUpdate Updates the current file with any relevant changes from the
120 " repository.
121 "
122 " VCSVimDiff Uses vimdiff to display differences between versions of the
123 " current file.
124 "
125 " If no revision is specified, the most recent version of the
126 " file on the current branch is used. With one argument,
127 " that argument is used as the revision as above. With two
128 " arguments, the differences between the two revisions is
129 " displayed using vimdiff.
130 "
131 " With either zero or one argument, the original buffer is
132 " used to perform the vimdiff. When the scratch buffer is
133 " closed, the original buffer will be returned to normal
134 " mode.
135 "
136 " Once vimdiff mode is started using the above methods,
137 " additional vimdiff buffers may be added by passing a single
138 " version argument to the command. There may be up to 4
139 " vimdiff buffers total.
140 "
141 " Using the 2-argument form of the command resets the vimdiff
142 " to only those 2 versions. Additionally, invoking the
143 " command on a different file will close the previous vimdiff
144 " buffers.
145 "
146 " Mapping documentation: {{{2
147 "
148 " By default, a mapping is defined for each command. User-provided mappings
149 " can be used instead by mapping to <Plug>CommandName, for instance:
150 "
151 " nmap ,ca <Plug>VCSAdd
152 "
153 " The default mappings are as follow:
154 "
155 " <Leader>ca VCSAdd
156 " <Leader>cn VCSAnnotate
157 " <Leader>cN VCSAnnotate!
158 " <Leader>cc VCSCommit
159 " <Leader>cD VCSDelete
160 " <Leader>cd VCSDiff
161 " <Leader>cg VCSGotoOriginal
162 " <Leader>cG VCSGotoOriginal!
163 " <Leader>ci VCSInfo
164 " <Leader>cl VCSLog
165 " <Leader>cL VCSLock
166 " <Leader>cr VCSReview
167 " <Leader>cs VCSStatus
168 " <Leader>cu VCSUpdate
169 " <Leader>cU VCSUnlock
170 " <Leader>cv VCSVimDiff
171 "
172 " Options documentation: {{{2
173 "
174 " Several variables are checked by the script to determine behavior as follow:
175 "
176 " VCSCommandCommitOnWrite
177 " This variable, if set to a non-zero value, causes the pending commit to
178 " take place immediately as soon as the log message buffer is written. If
179 " set to zero, only the VCSCommit mapping will cause the pending commit to
180 " occur. If not set, it defaults to 1.
181 "
182 " VCSCommandDeleteOnHide
183 " This variable, if set to a non-zero value, causes the temporary VCS result
184 " buffers to automatically delete themselves when hidden.
185 "
186 " VCSCommand{VCSType}DiffOpt
187 " This variable, if set, determines the options passed to the diff command
188 " of the underlying VCS. Each VCS plugin defines a default value.
189 "
190 " VCSCommandDiffSplit
191 " This variable overrides the VCSCommandSplit variable, but only for buffers
192 " created with VCSVimDiff.
193 "
194 " VCSCommandDisableAll
195 " This variable, if set, prevents the plugin or any extensions from loading
196 " at all. This is useful when a single runtime distribution is used on
197 " multiple systems with varying versions.
198 "
199 " VCSCommandDisableMappings
200 " This variable, if set to a non-zero value, prevents the default command
201 " mappings from being set.
202 "
203 " VCSCommandDisableExtensionMappings
204 " This variable, if set to a non-zero value, prevents the default command
205 " mappings from being set for commands specific to an individual VCS.
206 "
207 " VCSCommandDisableMenu
208 " This variable, if set to a non-zero value, prevents the default command
209 " menu from being set.
210 "
211 " VCSCommandEdit
212 " This variable controls whether to split the current window to display a
213 " scratch buffer ('split'), or to display it in the current buffer ('edit').
214 " If not set, it defaults to 'split'.
215 "
216 " VCSCommandEnableBufferSetup
217 " This variable, if set to a non-zero value, activates VCS buffer management
218 " mode. This mode means that the buffer variable 'VCSRevision' is set if
219 " the file is VCS-controlled. This is useful for displaying version
220 " information in the status bar. Additional options may be set by
221 " individual VCS plugins.
222 "
223 " VCSCommandMappings
224 " This variable, if set, overrides the default mappings used for shortcuts.
225 " It should be a List of 2-element Lists, each containing a shortcut and
226 " function name pair.
227 "
228 " VCSCommandMapPrefix
229 " This variable, if set, overrides the default mapping prefix ('<Leader>c').
230 " This allows customization of the mapping space used by the vcscommand
231 " shortcuts.
232 "
233 " VCSCommandMenuPriority
234 " This variable, if set, overrides the default menu priority '' (empty)
235 "
236 " VCSCommandMenuRoot
237 " This variable, if set, overrides the default menu root 'Plugin.VCS'
238 "
239 " VCSCommandResultBufferNameExtension
240 " This variable, if set to a non-blank value, is appended to the name of the
241 " VCS command output buffers. For example, '.vcs'. Using this option may
242 " help avoid problems caused by autocommands dependent on file extension.
243 "
244 " VCSCommandResultBufferNameFunction
245 " This variable, if set, specifies a custom function for naming VCS command
246 " output buffers. This function will be passed the following arguments:
247 "
248 " command - name of the VCS command being executed (such as 'Log' or
249 " 'Diff').
250 "
251 " originalBuffer - buffer number of the source file.
252 "
253 " vcsType - type of VCS controlling this file (such as 'CVS' or 'SVN').
254 "
255 " statusText - extra text associated with the VCS action (such as version
256 " numbers).
257 "
258 " VCSCommandSplit
259 " This variable controls the orientation of the various window splits that
260 " may occur (such as with VCSVimDiff, when using a VCS command on a VCS
261 " command buffer, or when the 'VCSCommandEdit' variable is set to 'split'.
262 " If set to 'horizontal', the resulting windows will be on stacked on top of
263 " one another. If set to 'vertical', the resulting windows will be
264 " side-by-side. If not set, it defaults to 'horizontal' for all but
265 " VCSVimDiff windows.
266 "
267 " VCSCommandVCSTypeOverride
268 " This variable allows the VCS type detection to be overridden on a
269 " path-by-path basis. The value of this variable is expected to be a List
270 " of Lists. Each high-level List item is a List containing two elements.
271 " The first element is a regular expression that will be matched against the
272 " full file name of a given buffer. If it matches, the second element will
273 " be used as the VCS type.
274 "
275 " VCSCommandVCSTypePreference
276 " This variable allows the VCS type detection to be weighted towards a
277 " specific VCS, in case more than one potential VCS is detected as useable.
278 " The format of the variable is either a list or a space-separated string
279 " containing the ordered-by-preference abbreviations of the preferred VCS
280 " types.
281 "
282 " Event documentation {{{2
283 " For additional customization, VCSCommand.vim uses User event autocommand
284 " hooks. Each event is in the VCSCommand group, and different patterns
285 " match the various hooks.
286 "
287 " For instance, the following could be added to the vimrc to provide a 'q'
288 " mapping to quit a VCS scratch buffer:
289 "
290 " augroup VCSCommand
291 " au VCSCommand User VCSBufferCreated silent! nmap <unique> <buffer> q :bwipeout<cr>
292 " augroup END
293 "
294 " The following hooks are available:
295 "
296 " VCSBufferCreated This event is fired just after a VCS command
297 " output buffer is created. It is executed
298 " within the context of the new buffer.
299 "
300 " VCSBufferSetup This event is fired just after VCS buffer setup
301 " occurs, if enabled.
302 "
303 " VCSPluginInit This event is fired when the VCSCommand plugin
304 " first loads.
305 "
306 " VCSPluginFinish This event is fired just after the VCSCommand
307 " plugin loads.
308 "
309 " VCSVimDiffFinish This event is fired just after the VCSVimDiff
310 " command executes to allow customization of,
311 " for instance, window placement and focus.
