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. | |

d839253b JF |
25 | Pager Mode |
26 | ~~~~~~~~~~ | |
27 | ||
28 | If stdin is a pipe, any log or diff options will be ignored and the pager view | |
29 | will be opened loading data from stdin. The pager mode can be used for | |
30 | colorizing output from various git commands. | |
31 | ||
32 | Example on how to colorize the output of git-show(1): | |
33 | ||

35 | $ git show | tig | |

d839253b JF |
39 | Git Command Options |
40 | ~~~~~~~~~~~~~~~~~~~ | |
41 | ||
42 | All git command options specified on the command line will be passed to the | |
43 | given command and all will be shell quoted before they are passed to the | |
44 | shell. | |
45 | ||
46 | NOTE: If you specify options for the main view, you should not use the | |
47 | `--pretty` option as this option will be set automatically to the format | |
48 | expected by the main view. | |
49 | ||
50 | Example on how to open the log view and show both author and committer | |
51 | information: | |
52 | ||
511147de JF |
53 | ----------------------------------------------------------------------------- |
54 | $ tig log --pretty=fuller | |
55 | ----------------------------------------------------------------------------- | |

56 | |
57 | See the <<refspec, "Specifying revisions">> section below for an introduction | |
58 | to revision options supported by the git commands. For details on specific git | |
59 | command options, refer to the man page of the command in question. | |

62 | Environment Variables |
63 | --------------------- | |
64 | ||
65 | Several options related to the interface with git can be configured via | |
66 | environment options. | |
67 | ||
9783cb12 | 68 | [[repo-refs]] |
d839253b JF |
69 | Repository References |
70 | ~~~~~~~~~~~~~~~~~~~~~ | |
71 | ||
72 | Commits that are referenced by tags and branch heads will be marked by the | |
73 | reference name surrounded by '[' and ']': | |
74 | ||

78 | |
79 | If you want to filter out certain directories under `.git/refs/`, say `tmp` | |
80 | you can do it by setting the following variable: | |
81 | ||
511147de JF |
82 | ----------------------------------------------------------------------------- |
83 | $ TIG_LS_REMOTE="git ls-remote . | sed /\/tmp\//d" tig | |
84 | ----------------------------------------------------------------------------- | |
d839253b JF |
85 | |
86 | Or set the variable permanently in your environment. | |
87 | ||
88 | TIG_LS_REMOTE:: | |
89 | Set command for retrieving all repository references. The command | |
90 | should output data in the same format as git-ls-remote(1). | |
91 | ||
92 | [[history-commands]] | |
93 | History Commands | |
94 | ~~~~~~~~~~~~~~~~ | |
95 | ||
96 | It is possible to alter which commands are used for the different views. If | |
97 | for example you prefer commits in the main view to be sorted by date and only | |
98 | show 500 commits, use: | |
99 | ||
511147de JF |
100 | ----------------------------------------------------------------------------- |
101 | $ TIG_MAIN_CMD="git log --date-order -n500 --pretty=raw %s" tig | |
102 | ----------------------------------------------------------------------------- | |
d839253b JF |
103 | |
104 | Or set the variable permanently in your environment. | |
105 | ||
106 | Notice, how `%s` is used to specify the commit reference. There can be a | |
107 | maximum of 5 `%s` ref specifications. | |
108 | ||
109 | TIG_DIFF_CMD:: | |
110 | The command used for the diff view. By default, git show is used | |
111 | as a backend. | |
112 | ||
113 | TIG_LOG_CMD:: | |
114 | The command used for the log view. If you prefer to have both | |
115 | author and committer shown in the log view be sure to pass | |
116 | `--pretty=fuller` to git log. | |
117 | ||
118 | TIG_MAIN_CMD:: | |
119 | The command used for the main view. Note, you must always specify | |
120 | the option: `--pretty=raw` since the main view parser expects to | |
121 | read that format. | |
122 | ||
9783cb12 | 123 | [[viewer]] |
d839253b JF |
124 | The Viewer |
125 | ---------- | |
126 | ||
127 | The display consists of a status window on the last line of the screen and one | |
128 | or more views. The default is to only show one view at the time but it is | |
129 | possible to split both the main and log view to also show the commit diff. | |
130 | ||
131 | If you are in the log view and press 'Enter' when the current line is a commit | |
132 | line, such as: | |
133 | ||
511147de JF |
134 | ----------------------------------------------------------------------------- |
135 | commit 4d55caff4cc89335192f3e566004b4ceef572521 | |
136 | ----------------------------------------------------------------------------- | |
d839253b JF |
137 | |
138 | You will split the view so that the log view is displayed in the top window | |
139 | and the diff view in the bottom window. You can switch between the two views | |
140 | by pressing 'Tab'. To maximize the log view again, simply press 'l'. | |
141 | ||
9783cb12 | 142 | [[commit-id]] |
d839253b JF |
143 | Current Head and Commit ID |
144 | ~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
145 | ||
146 | The viewer keeps track of both what head and commit ID you are currently | |
147 | viewing. The commit ID will follow the cursor line and change everytime time | |
148 | you highlight a different commit. Whenever you reopen the diff view it will be | |
149 | reloaded, if the commit ID changed. | |
150 | ||
151 | The head ID is used when opening the main and log view to indicate from what | |
152 | revision to show history. | |
153 | ||
9783cb12 | 154 | [[views]] |
d839253b JF |
155 | Views |
156 | ~~~~~ | |
157 | ||
511147de | 158 | Various 'views' of a repository is presented. Each view is based on output |
d839253b JF |
159 | from an external command, most often 'git log', 'git diff', or 'git show'. |
160 | ||
161 | The main view:: | |
162 | Is the default view, and it shows a one line summary of each commit | |
163 | in the chosen list of revisions. The summary includes commit date, | |
164 | author, and the first line of the log message. Additionally, any | |
165 | repository references, such as tags, will be shown. | |
166 | ||
167 | The log view:: | |
168 | Presents a more rich view of the revision log showing the whole log | |
169 | message and the diffstat. | |
170 | ||
171 | The diff view:: | |
172 | Shows either the diff of the current working tree, that is, what | |
173 | has changed since the last commit, or the commit diff complete | |
174 | with log message, diffstat and diff. | |
175 | ||
176 | The pager view:: | |
177 | Is used for displaying both input from stdin and output from git | |
178 | commands entered in the internal prompt. | |
179 | ||
180 | The help view:: | |
24b5b3e0 | 181 | Displays key binding quick reference. |
d839253b | 182 | |
9783cb12 | 183 | [[title-window]] |
d839253b JF |
184 | Title Windows |
185 | ~~~~~~~~~~~~~ | |
186 | ||
187 | Each view has a title window which shows the name of the view, current commit | |
188 | ID if available, and where the view is positioned: | |
189 | ||
511147de JF |
190 | ----------------------------------------------------------------------------- |
191 | [main] c622eefaa485995320bc743431bae0d497b1d875 - commit 1 of 61 (1%) | |
192 | ----------------------------------------------------------------------------- | |
d839253b JF |
193 | |
194 | By default, the title of the current view is highlighted using bold font. For | |
195 | long loading views (taking over 3 seconds) the time since loading started will | |
196 | be appended: | |
197 | ||
511147de JF |
198 | ----------------------------------------------------------------------------- |
199 | [main] 77d9e40fbcea3238015aea403e06f61542df9a31 - commit 1 of 779 (0%) 5s | |

291 | |
292 | [[refspec]] | |
293 | Revision Specification | |
294 | ---------------------- | |
295 | ||
296 | This section describes various ways to specify what revisions to display or | |
511147de | 297 | otherwise limit the view to. Tig does not itself parse the described |
d839253b JF |
298 | revision options so refer to the relevant git man pages for futher |
299 | information. Relevant man pages besides git-log(1) are git-diff(1) and | |
300 | git-rev-list(1). | |
301 | ||
302 | You can tune the interaction with git by making use of the options explained | |
303 | in this section. For example, by configuring the environment variables | |
304 | described in the <<history-commands, "History commands">> section. | |
305 | ||
9783cb12 | 306 | [[path-limiting]] |
d839253b JF |
307 | Limit by Path Name |
308 | ~~~~~~~~~~~~~~~~~~ | |
309 | ||
310 | If you are interested only in those revisions that made changes to a specific | |
311 | file (or even several files) list the files like this: | |
312 | ||
511147de JF |
313 | ----------------------------------------------------------------------------- |
314 | $ tig log Makefile README | |
315 | ----------------------------------------------------------------------------- | |
d839253b JF |
316 | |
317 | To avoid ambiguity with repository references such as tag name, be sure to | |
318 | separate file names from other git options using "\--". So if you have a file | |
319 | named 'master' it will clash with the reference named 'master', and thus you | |
320 | will have to use: | |
321 | ||
511147de JF |
322 | ----------------------------------------------------------------------------- |
323 | $ tig log -- master | |
324 | ----------------------------------------------------------------------------- | |
d839253b JF |
325 | |
326 | NOTE: For the main view, avoiding ambiguity will in some cases require you to | |
511147de | 327 | specify two "\--" options. The first will make tig stop option processing |
d839253b JF |
328 | and the latter will be passed to git log. |
329 | ||
9783cb12 | 330 | [[date-number-limiting]] |
d839253b JF |
331 | Limit by Date or Number |
332 | ~~~~~~~~~~~~~~~~~~~~~~~ | |
333 | ||
334 | To speed up interaction with git, you can limit the amount of commits to show | |
335 | both for the log and main view. Either limit by date using e.g. | |
336 | `--since=1.month` or limit by the number of commits using `-n400`. | |
337 | ||
338 | If you are only interested in changed that happened between two dates you can | |
339 | use: | |
340 | ||
511147de JF |
341 | ----------------------------------------------------------------------------- |
342 | $ tig -- --after="May 5th" --before="2006-05-16 15:44" | |
343 | ----------------------------------------------------------------------------- | |
d839253b JF |
344 | |
345 | NOTE: If you want to avoid having to quote dates containing spaces you can use | |
346 | "." instead, e.g. `--after=May.5th`. | |
347 | ||
9783cb12 | 348 | [[commit-range-limiting]] |
d839253b JF |
349 | Limiting by Commit Ranges |
350 | ~~~~~~~~~~~~~~~~~~~~~~~~~ | |
351 | ||
352 | Alternatively, commits can be limited to a specific range, such as "all | |
353 | commits between 'tag-1.0' and 'tag-2.0'". For example: | |
354 | ||
511147de JF |
355 | ----------------------------------------------------------------------------- |
356 | $ tig log tag-1.0..tag-2.0 | |
357 | ----------------------------------------------------------------------------- | |
d839253b JF |
358 | |
359 | This way of commit limiting makes it trivial to only browse the commits which | |
360 | haven't been pushed to a remote branch. Assuming 'origin' is your upstream | |
361 | remote branch, using: | |
362 | ||
511147de JF |
363 | ----------------------------------------------------------------------------- |
364 | $ tig log origin..HEAD | |
365 | ----------------------------------------------------------------------------- | |
d839253b JF |
366 | |
367 | will list what will be pushed to the remote branch. Optionally, the ending | |
368 | 'HEAD' can be left out since it is implied. | |
369 | ||
9783cb12 | 370 | [[reachability-limiting]] |
d839253b JF |
371 | Limiting by Reachability |
372 | ~~~~~~~~~~~~~~~~~~~~~~~~ | |
373 | ||
374 | Git interprets the range specifier "tag-1.0..tag-2.0" as "all commits | |
375 | reachable from 'tag-2.0' but not from 'tag-1.0'". Where reachability refers | |
376 | to what commits are ancestors (or part of the history) of the branch or tagged | |
377 | revision in question. | |
378 | ||
379 | If you prefer to specify which commit to preview in this way use the | |
380 | following: | |
381 | ||
511147de JF |
382 | ----------------------------------------------------------------------------- |
383 | $ tig log tag-2.0 ^tag-1.0 | |
384 | ----------------------------------------------------------------------------- | |
d839253b JF |
385 | |
386 | You can think of '^' as a negation operator. Using this alternate syntax, it | |
387 | is possible to further prune commits by specifying multiple branch cut offs. | |
388 | ||
9783cb12 | 389 | [[refspec-combi]] |
d839253b JF |
390 | Combining Revisions Specification |
391 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
392 | ||
393 | Revisions options can to some degree be combined, which makes it possible to | |
394 | say "show at most 20 commits from within the last month that changed files | |
395 | under the Documentation/ directory." | |
396 | ||
511147de JF |
397 | ----------------------------------------------------------------------------- |
398 | $ tig -- --since=1.month -n20 -- Documentation/ | |
399 | ----------------------------------------------------------------------------- | |

d839253b JF |
402 | Examining All Repository References |
403 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
404 | ||
405 | In some cases, it can be useful to query changes across all references in a | |
406 | repository. An example is to ask "did any line of development in this | |
407 | repository change a particular file within the last week". This can be | |
408 | accomplished using: | |
409 | ||
511147de JF |
410 | ----------------------------------------------------------------------------- |
411 | $ tig -- --all --since=1.week -- Makefile | |
412 | ----------------------------------------------------------------------------- | |
