| 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 key binding quick reference. |
| 156 | |
| 157 | Title Windows |
| 158 | ~~~~~~~~~~~~~ |
| 159 | |
| 160 | Each view has a title window which shows the name of the view, current commit |
| 161 | ID if available, and where the view is positioned: |
| 162 | |
| 163 | [main] c622eefaa485995320bc743431bae0d497b1d875 - commit 1 of 61 (1%) |
| 164 | |
| 165 | By default, the title of the current view is highlighted using bold font. For |
| 166 | long loading views (taking over 3 seconds) the time since loading started will |
| 167 | be appended: |
| 168 | |
| 169 | [main] 77d9e40fbcea3238015aea403e06f61542df9a31 - commit 1 of 779 (0%) 5s |
| 170 | |
| 171 | Keys |
| 172 | ---- |
| 173 | Below the default key bindings are shown. |
| 174 | |
| 175 | View Switching |
| 176 | ~~~~~~~~~~~~~~ |
| 177 | m:: |
| 178 | Switch to main view. |
| 179 | d:: |
| 180 | Switch to diff view. |
| 181 | l:: |
| 182 | Switch to log view. |
| 183 | p:: |
| 184 | Switch to pager view. |
| 185 | h, ?:: |
| 186 | Show man page. |
| 187 | |
| 188 | View Manipulation |
| 189 | ~~~~~~~~~~~~~~~~~ |
| 190 | q:: |
| 191 | Close view, if multiple views are open it will jump back to the |
| 192 | previous view in the view stack. If it is the last open view it |
| 193 | will quit. Use 'Q' to quit all views at once. |
| 194 | Enter:: |
| 195 | This key is "context sensitive" depending on what view you are |
| 196 | currently in. When in log view on a commit line or in the main |
| 197 | view, split the view and show the commit diff. In the diff view |
| 198 | pressing Enter will simply scroll the view one line down. |
| 199 | Tab:: |
| 200 | Switch to next view. |
| 201 | Up:: |
| 202 | This key is "context sensitive" and will move the cursor one |
| 203 | line up. However, uf you opened a diff view from the main view |
| 204 | (split- or full-screen) it will change the cursor to point to |
| 205 | the previous commit in the main view and update the diff view |
| 206 | to display it. |
| 207 | Down:: |
| 208 | Similar to 'Up' but will move down. |
| 209 | |
| 210 | Cursor Navigation |
| 211 | ~~~~~~~~~~~~~~~~~ |
| 212 | j:: |
| 213 | Move cursor one line up. |
| 214 | k:: |
| 215 | Move cursor one line down. |
| 216 | PgUp:: |
| 217 | b:: |
| 218 | -:: |
| 219 | Move cursor one page up. |
| 220 | PgDown:: |
| 221 | Space:: |
| 222 | Move cursor one page down. |
| 223 | Home:: |
| 224 | Jump to first line. |
| 225 | End:: |
| 226 | Jump to last line. |
| 227 | |
| 228 | Scrolling |
| 229 | ~~~~~~~~~ |
| 230 | Insert:: |
| 231 | Scroll view one line up. |
| 232 | Delete:: |
| 233 | Scroll view one line down. |
| 234 | w:: |
| 235 | Scroll view one page up. |
| 236 | s:: |
| 237 | Scroll view one page down. |
| 238 | |
| 239 | Misc |
| 240 | ~~~~ |
| 241 | Q:: |
| 242 | Quit. |
| 243 | r:: |
| 244 | Redraw screen. |
| 245 | z:: |
| 246 | Stop all background loading. This can be useful if you use |
| 247 | tig(1) in a repository with a long history without limiting |
| 248 | the revision log. |
| 249 | v:: |
| 250 | Show version. |
| 251 | n:: |
| 252 | Toggle line numbers on/off. |
| 253 | g:: |
| 254 | Toggle revision graph visualization on/off. |
| 255 | ':':: |
| 256 | Open prompt. This allows you to specify what git command |
| 257 | to run. Example: |
| 258 | |
| 259 | :log -p |
| 260 | |
| 261 | [[refspec]] |
| 262 | Revision Specification |
| 263 | ---------------------- |
| 264 | |
| 265 | This section describes various ways to specify what revisions to display or |
| 266 | otherwise limit the view to. tig(1) does not itself parse the described |
| 267 | revision options so refer to the relevant git man pages for futher |
| 268 | information. Relevant man pages besides git-log(1) are git-diff(1) and |
| 269 | git-rev-list(1). |
| 270 | |
| 271 | You can tune the interaction with git by making use of the options explained |
| 272 | in this section. For example, by configuring the environment variables |
| 273 | described in the <<history-commands, "History commands">> section. |
| 274 | |
| 275 | Limit by Path Name |
| 276 | ~~~~~~~~~~~~~~~~~~ |
| 277 | |
| 278 | If you are interested only in those revisions that made changes to a specific |
| 279 | file (or even several files) list the files like this: |
| 280 | |
| 281 | $ tig log Makefile README |
| 282 | |
| 283 | To avoid ambiguity with repository references such as tag name, be sure to |
| 284 | separate file names from other git options using "\--". So if you have a file |
| 285 | named 'master' it will clash with the reference named 'master', and thus you |
| 286 | will have to use: |
| 287 | |
| 288 | $ tig log -- master |
| 289 | |
| 290 | NOTE: For the main view, avoiding ambiguity will in some cases require you to |
| 291 | specify two "\--" options. The first will make tig(1) stop option processing |
| 292 | and the latter will be passed to git log. |
| 293 | |
| 294 | Limit by Date or Number |
| 295 | ~~~~~~~~~~~~~~~~~~~~~~~ |
| 296 | |
| 297 | To speed up interaction with git, you can limit the amount of commits to show |
| 298 | both for the log and main view. Either limit by date using e.g. |
| 299 | `--since=1.month` or limit by the number of commits using `-n400`. |
| 300 | |
| 301 | If you are only interested in changed that happened between two dates you can |
| 302 | use: |
| 303 | |
| 304 | $ tig -- --after="May 5th" --before="2006-05-16 15:44" |
| 305 | |
| 306 | NOTE: If you want to avoid having to quote dates containing spaces you can use |
| 307 | "." instead, e.g. `--after=May.5th`. |
| 308 | |
| 309 | Limiting by Commit Ranges |
| 310 | ~~~~~~~~~~~~~~~~~~~~~~~~~ |
| 311 | |
| 312 | Alternatively, commits can be limited to a specific range, such as "all |
| 313 | commits between 'tag-1.0' and 'tag-2.0'". For example: |
| 314 | |
| 315 | $ tig log tag-1.0..tag-2.0 |
| 316 | |
| 317 | This way of commit limiting makes it trivial to only browse the commits which |
| 318 | haven't been pushed to a remote branch. Assuming 'origin' is your upstream |
| 319 | remote branch, using: |
| 320 | |
| 321 | $ tig log origin..HEAD |
| 322 | |
| 323 | will list what will be pushed to the remote branch. Optionally, the ending |
| 324 | 'HEAD' can be left out since it is implied. |
| 325 | |
| 326 | Limiting by Reachability |
| 327 | ~~~~~~~~~~~~~~~~~~~~~~~~ |
| 328 | |
| 329 | Git interprets the range specifier "tag-1.0..tag-2.0" as "all commits |
| 330 | reachable from 'tag-2.0' but not from 'tag-1.0'". Where reachability refers |
| 331 | to what commits are ancestors (or part of the history) of the branch or tagged |
| 332 | revision in question. |
| 333 | |
| 334 | If you prefer to specify which commit to preview in this way use the |
| 335 | following: |
| 336 | |
| 337 | $ tig log tag-2.0 ^tag-1.0 |
| 338 | |
| 339 | You can think of '^' as a negation operator. Using this alternate syntax, it |
| 340 | is possible to further prune commits by specifying multiple branch cut offs. |
| 341 | |
| 342 | Combining Revisions Specification |
| 343 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| 344 | |
| 345 | Revisions options can to some degree be combined, which makes it possible to |
| 346 | say "show at most 20 commits from within the last month that changed files |
| 347 | under the Documentation/ directory." |
| 348 | |
| 349 | $ tig -- --since=1.month -n20 -- Documentation/ |
| 350 | |
| 351 | Examining All Repository References |
| 352 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| 353 | |
| 354 | In some cases, it can be useful to query changes across all references in a |
| 355 | repository. An example is to ask "did any line of development in this |
| 356 | repository change a particular file within the last week". This can be |
| 357 | accomplished using: |
| 358 | |
| 359 | $ tig -- --all --since=1.week -- Makefile |
