1 | The tig Manual |
2 | ============== | |
3 | Jonas Fonseca <fonseca@diku.dk> | |
4 | ||
5 | This is the manual for tig, the ncurses-based text-mode interface for git. | |
6 | Tig allows you to browse changes in a git repository and can additionally act | |
7 | as a pager for output of various git commands. When used as a pager, it will | |
8 | display input from stdin and colorize it. | |
9 | ||
10 | When browsing repositories, tig uses the underlying git commands to present | |
11 | the user with various views, such as summarized commit log and showing the | |
12 | commit with the log message, diffstat, and the diff. | |
13 | ||
14 | Calling Conventions | |
15 | ------------------- | |
16 | ||
17 | Pager Mode | |
18 | ~~~~~~~~~~ | |
19 | ||
20 | If stdin is a pipe, any log or diff options will be ignored and the pager view | |
21 | will be opened loading data from stdin. The pager mode can be used for | |
22 | colorizing output from various git commands. | |
23 | ||
24 | Example on how to colorize the output of git-show(1): | |
25 | ||
26 | $ git show | tig | |
27 | ||
28 | Git Command Options | |
29 | ~~~~~~~~~~~~~~~~~~~ | |
30 | ||
31 | All git command options specified on the command line will be passed to the | |
32 | given command and all will be shell quoted before they are passed to the | |
33 | shell. | |
34 | ||
35 | NOTE: If you specify options for the main view, you should not use the | |
36 | `--pretty` option as this option will be set automatically to the format | |
37 | expected by the main view. | |
38 | ||
39 | Example on how to open the log view and show both author and committer | |
40 | information: | |
41 | ||
42 | $ tig log --pretty=fuller | |
43 | ||
44 | See the <<refspec, "Specifying revisions">> section below for an introduction | |
45 | to revision options supported by the git commands. For details on specific git | |
46 | command options, refer to the man page of the command in question. | |
47 | ||
48 | Environment Variables | |
49 | --------------------- | |
50 | ||
51 | Several options related to the interface with git can be configured via | |
52 | environment options. | |
53 | ||
54 | Repository References | |
55 | ~~~~~~~~~~~~~~~~~~~~~ | |
56 | ||
57 | Commits that are referenced by tags and branch heads will be marked by the | |
58 | reference name surrounded by '[' and ']': | |
59 | ||

61 | ||
62 | If you want to filter out certain directories under `.git/refs/`, say `tmp` | |
63 | you can do it by setting the following variable: | |
64 | ||
65 | $ TIG_LS_REMOTE="git ls-remote . | sed /\/tmp\//d" tig | |
66 | ||
67 | Or set the variable permanently in your environment. | |
68 | ||
69 | TIG_LS_REMOTE:: | |
70 | Set command for retrieving all repository references. The command | |
71 | should output data in the same format as git-ls-remote(1). | |
72 | ||
73 | [[history-commands]] | |
74 | History Commands | |
75 | ~~~~~~~~~~~~~~~~ | |
76 | ||
77 | It is possible to alter which commands are used for the different views. If | |
78 | for example you prefer commits in the main view to be sorted by date and only | |
79 | show 500 commits, use: | |
80 | ||
81 | $ TIG_MAIN_CMD="git log --date-order -n500 --pretty=raw %s" tig | |
82 | ||
83 | Or set the variable permanently in your environment. | |
84 | ||
85 | Notice, how `%s` is used to specify the commit reference. There can be a | |
86 | maximum of 5 `%s` ref specifications. | |
87 | ||
88 | TIG_DIFF_CMD:: | |
89 | The command used for the diff view. By default, git show is used | |
90 | as a backend. | |
91 | ||
92 | TIG_LOG_CMD:: | |
93 | The command used for the log view. If you prefer to have both | |
94 | author and committer shown in the log view be sure to pass | |
95 | `--pretty=fuller` to git log. | |
96 | ||
97 | TIG_MAIN_CMD:: | |
98 | The command used for the main view. Note, you must always specify | |
99 | the option: `--pretty=raw` since the main view parser expects to | |
100 | read that format. | |
101 | ||
102 | The Viewer | |
103 | ---------- | |
104 | ||
105 | The display consists of a status window on the last line of the screen and one | |
106 | or more views. The default is to only show one view at the time but it is | |
107 | possible to split both the main and log view to also show the commit diff. | |
108 | ||
109 | If you are in the log view and press 'Enter' when the current line is a commit | |
110 | line, such as: | |
111 | ||
112 | commit 4d55caff4cc89335192f3e566004b4ceef572521 | |
113 | ||
114 | You will split the view so that the log view is displayed in the top window | |
115 | and the diff view in the bottom window. You can switch between the two views | |
116 | by pressing 'Tab'. To maximize the log view again, simply press 'l'. | |
117 | ||
118 | Current Head and Commit ID | |
119 | ~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
120 | ||
121 | The viewer keeps track of both what head and commit ID you are currently | |
122 | viewing. The commit ID will follow the cursor line and change everytime time | |
123 | you highlight a different commit. Whenever you reopen the diff view it will be | |
124 | reloaded, if the commit ID changed. | |
125 | ||
126 | The head ID is used when opening the main and log view to indicate from what | |
127 | revision to show history. | |
128 | ||
129 | Views | |
130 | ~~~~~ | |
131 | ||
132 | tig(1) presents various 'views' of a repository. Each view is based on output | |
133 | from an external command, most often 'git log', 'git diff', or 'git show'. | |
134 | ||
135 | The main view:: | |
136 | Is the default view, and it shows a one line summary of each commit | |
137 | in the chosen list of revisions. The summary includes commit date, | |
138 | author, and the first line of the log message. Additionally, any | |
139 | repository references, such as tags, will be shown. | |
140 | ||
141 | The log view:: | |
142 | Presents a more rich view of the revision log showing the whole log | |
143 | message and the diffstat. | |
144 | ||
145 | The diff view:: | |
146 | Shows either the diff of the current working tree, that is, what | |
147 | has changed since the last commit, or the commit diff complete | |
148 | with log message, diffstat and diff. | |
149 | ||
150 | The pager view:: | |
151 | Is used for displaying both input from stdin and output from git | |
152 | commands entered in the internal prompt. | |
153 | ||
154 | The help view:: | |
155 | Displays the information from the tig(1) man page. For the help view | |
156 | to work you need to have the tig(1) man page installed. | |
157 | ||
158 | Title Windows | |
159 | ~~~~~~~~~~~~~ | |
160 | ||
161 | Each view has a title window which shows the name of the view, current commit | |
162 | ID if available, and where the view is positioned: | |
163 | ||
164 | [main] c622eefaa485995320bc743431bae0d497b1d875 - commit 1 of 61 (1%) | |
165 | ||
166 | By default, the title of the current view is highlighted using bold font. For | |
167 | long loading views (taking over 3 seconds) the time since loading started will | |
168 | be appended: | |
169 | ||
170 | [main] 77d9e40fbcea3238015aea403e06f61542df9a31 - commit 1 of 779 (0%) 5s | |
171 | ||
172 | Keys | |
173 | ---- | |
174 | Below the default key bindings are shown. | |
175 | ||
176 | View Switching | |
177 | ~~~~~~~~~~~~~~ | |
178 | m:: | |
179 | Switch to main view. | |
180 | d:: | |
181 | Switch to diff view. | |
182 | l:: | |
183 | Switch to log view. | |
184 | p:: | |
185 | Switch to pager view. | |
186 | h:: | |
187 | Show man page. | |
188 | ||
189 | View Manipulation | |
190 | ~~~~~~~~~~~~~~~~~ | |
191 | q:: | |
192 | Close view, if multiple views are open it will jump back to the | |
193 | previous view in the view stack. If it is the last open view it | |
194 | will quit. Use 'Q' to quit all views at once. | |
195 | Enter:: | |
196 | This key is "context sensitive" depending on what view you are | |
197 | currently in. When in log view on a commit line or in the main | |
198 | view, split the view and show the commit diff. In the diff view | |
199 | pressing Enter will simply scroll the view one line down. | |
200 | Tab:: | |
201 | Switch to next view. | |
202 | Up:: | |
203 | This key is "context sensitive" and will move the cursor one | |
204 | line up. However, uf you opened a diff view from the main view | |
205 | (split- or full-screen) it will change the cursor to point to | |
206 | the previous commit in the main view and update the diff view | |
207 | to display it. | |
208 | Down:: | |
209 | Similar to 'Up' but will move down. | |
210 | ||
211 | Cursor Navigation | |
212 | ~~~~~~~~~~~~~~~~~ | |
213 | j:: | |
214 | Move cursor one line up. | |
215 | k:: | |
216 | Move cursor one line down. | |
217 | PgUp:: | |
218 | b:: | |
219 | -:: | |
220 | Move cursor one page up. | |
221 | PgDown:: | |
222 | Space:: | |
223 | Move cursor one page down. | |
224 | Home:: | |
225 | Jump to first line. | |
226 | End:: | |
227 | Jump to last line. | |
228 | ||
229 | Scrolling | |
230 | ~~~~~~~~~ | |
231 | Insert:: | |
232 | Scroll view one line up. | |
233 | Delete:: | |
234 | Scroll view one line down. | |
235 | w:: | |
236 | Scroll view one page up. | |
237 | s:: | |
238 | Scroll view one page down. | |
239 | ||
240 | Misc | |
241 | ~~~~ | |
242 | Q:: | |
243 | Quit. | |
244 | r:: | |
245 | Redraw screen. | |
246 | z:: | |
247 | Stop all background loading. This can be useful if you use | |
248 | tig(1) in a repository with a long history without limiting | |
249 | the revision log. | |
250 | v:: | |
251 | Show version. | |
252 | n:: | |
253 | Toggle line numbers on/off. | |
254 | ':':: | |
255 | Open prompt. This allows you to specify what git command | |
256 | to run. Example: | |
257 | ||
258 | :log -p | |
259 | ||
260 | [[refspec]] | |
261 | Revision Specification | |
262 | ---------------------- | |
263 | ||
264 | This section describes various ways to specify what revisions to display or | |
265 | otherwise limit the view to. tig(1) does not itself parse the described | |
266 | revision options so refer to the relevant git man pages for futher | |
267 | information. Relevant man pages besides git-log(1) are git-diff(1) and | |
268 | git-rev-list(1). | |
269 | ||
270 | You can tune the interaction with git by making use of the options explained | |
271 | in this section. For example, by configuring the environment variables | |
272 | described in the <<history-commands, "History commands">> section. | |
273 | ||
274 | Limit by Path Name | |
275 | ~~~~~~~~~~~~~~~~~~ | |
276 | ||
277 | If you are interested only in those revisions that made changes to a specific | |
278 | file (or even several files) list the files like this: | |
279 | ||
280 | $ tig log Makefile README | |
281 | ||
282 | To avoid ambiguity with repository references such as tag name, be sure to | |
283 | separate file names from other git options using "\--". So if you have a file | |
284 | named 'master' it will clash with the reference named 'master', and thus you | |
285 | will have to use: | |
286 | ||
287 | $ tig log -- master | |
288 | ||
289 | NOTE: For the main view, avoiding ambiguity will in some cases require you to | |
290 | specify two "\--" options. The first will make tig(1) stop option processing | |
291 | and the latter will be passed to git log. | |
292 | ||
293 | Limit by Date or Number | |
294 | ~~~~~~~~~~~~~~~~~~~~~~~ | |
295 | ||
296 | To speed up interaction with git, you can limit the amount of commits to show | |
297 | both for the log and main view. Either limit by date using e.g. | |
298 | `--since=1.month` or limit by the number of commits using `-n400`. | |
299 | ||
300 | If you are only interested in changed that happened between two dates you can | |
301 | use: | |
302 | ||
303 | $ tig -- --after="May 5th" --before="2006-05-16 15:44" | |
304 | ||
305 | NOTE: If you want to avoid having to quote dates containing spaces you can use | |
306 | "." instead, e.g. `--after=May.5th`. | |
307 | ||
308 | Limiting by Commit Ranges | |
309 | ~~~~~~~~~~~~~~~~~~~~~~~~~ | |
310 | ||
311 | Alternatively, commits can be limited to a specific range, such as "all | |
312 | commits between 'tag-1.0' and 'tag-2.0'". For example: | |
313 | ||
314 | $ tig log tag-1.0..tag-2.0 | |
315 | ||
316 | This way of commit limiting makes it trivial to only browse the commits which | |
317 | haven't been pushed to a remote branch. Assuming 'origin' is your upstream | |
318 | remote branch, using: | |
319 | ||
320 | $ tig log origin..HEAD | |
321 | ||
322 | will list what will be pushed to the remote branch. Optionally, the ending | |
323 | 'HEAD' can be left out since it is implied. | |
324 | ||
325 | Limiting by Reachability | |
326 | ~~~~~~~~~~~~~~~~~~~~~~~~ | |
327 | ||
328 | Git interprets the range specifier "tag-1.0..tag-2.0" as "all commits | |
329 | reachable from 'tag-2.0' but not from 'tag-1.0'". Where reachability refers | |
330 | to what commits are ancestors (or part of the history) of the branch or tagged | |
331 | revision in question. | |
332 | ||
333 | If you prefer to specify which commit to preview in this way use the | |
334 | following: | |
335 | ||
336 | $ tig log tag-2.0 ^tag-1.0 | |
337 | ||
338 | You can think of '^' as a negation operator. Using this alternate syntax, it | |
339 | is possible to further prune commits by specifying multiple branch cut offs. | |
340 | ||
341 | Combining Revisions Specification | |
342 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
343 | ||
344 | Revisions options can to some degree be combined, which makes it possible to | |
345 | say "show at most 20 commits from within the last month that changed files | |
346 | under the Documentation/ directory." | |
347 | ||
348 | $ tig -- --since=1.month -n20 -- Documentation/ | |
349 | ||
350 | Examining All Repository References | |
351 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
352 | ||
353 | In some cases, it can be useful to query changes across all references in a | |
354 | repository. An example is to ask "did any line of development in this | |
355 | repository change a particular file within the last week". This can be | |
356 | accomplished using: | |
357 | ||
358 | $ tig -- --all --since=1.week -- Makefile | |
