 268 <p>tig -
 269    text-mode interface for git
 270 </p>

 274 <div class="sectionbody">
 275 <div class="verseblock">
 276 <div class="content">tig [options]
 277 tig [options] [--] [git log options]
 278 tig [options] log  [git log options]

 282 </div>
 283 <h2>DESCRIPTION</h2>
 284 <div class="sectionbody">
 285 <p>Browse changes in a git repository. Additionally, tig(1) can also act
 286 as a pager for output of various git commands.</p>
 287 <p>When browsing repositories, tig(1) uses the underlying git commands
 288 to present the user with various views, such as summarized commit log
 289 and showing the commit with the log message, diffstat, and the diff.</p>
 290 <p>Using tig(1) as a pager, it will display input from stdin and try
 291 to colorize it.</p>
 292 </div>

 350         End of tig(1) options. Useful when specifying command
 351         options for the main view. Example:
 352 </p>
 353 <div class="literalblock">
 354 <div class="content">
 355 <pre><tt>$ tig -- --since=1.month</tt></pre>
 356 </div></div>
 357 </dd>
 358 <dt>
 359 log [git log options]
 360 </dt>
 361 <dd>
 362 <p>
 363         Open log view using the given git log options.
 364 </p>
 365 </dd>
 366 <dt>
 367 diff [git diff options]
 368 </dt>
 369 <dd>
 370 <p>
 371         Open diff view using the given git diff options.
 372 </p>
 373 </dd>
 374 <dt>
 375 show [git show options]
 376 </dt>
 377 <dd>
 378 <p>
 379         Open diff view using the given git show options.
 380 </p>
 381 </dd>
 382 <dt>
 383 [git log options]
 384 </dt>
 385 <dd>
 386 <p>
 387         tig(1) will stop the option parsing when the first
 388         command line parameter not starting with "-" is
 389         encountered. All options including this one will be
 390         passed to git log when loading the main view.
 391         This makes it possible to say:
 392 </p>
 393 <div class="literalblock">
 394 <div class="content">
 395 <pre><tt>$ tig tag-1.0..HEAD</tt></pre>
 396 </div></div>
 397 </dd>
 398 </dl>
 399 <h3>Pager mode</h3>
 400 <p>If stdin is a pipe, any log or diff options will be ignored and the
 401 pager view will be opened loading data from stdin. The pager mode
 402 can be used for colorizing output from various git commands.</p>
 403 <p>Example on how to colorize the output of git-show(1):</p>
 404 <div class="literalblock">
 405 <div class="content">
 406 <pre><tt>$ git show | tig</tt></pre>
 407 </div></div>
 408 <h3>Git command options</h3>
 409 <p>All git command options specified on the command line will
 410 be passed to the given command and all will be shell quoted
 411 before they are passed to the shell.</p>
 412 <div class="admonitionblock">
 413 <table><tr>
 414 <td class="icon">
 415 <div class="title">Note</div>
 416 </td>
 417 <td class="content">If you specify options for the main view, you should
 418 not use the <tt>--pretty</tt> option as this option will be set
 419 automatically to the format expected by the main view.</td>
 420 </tr></table>
 421 </div>
 422 <p>Example on how to open the log view and show both author and
 423 committer information:</p>
 424 <div class="literalblock">
 425 <div class="content">
 426 <pre><tt>$ tig log --pretty=fuller</tt></pre>
 427 </div></div>
 428 <p>See the <a href="#refspec">"Specifying revisions"</a> section below
 429 for an introduction to revision options supported by the git
 430 commands. For details on specific git command options, refer
 431 to the man page of the command in question.</p>
 432 </div>
 433 <h2>ENVIRONMENT VARIABLES</h2>
 434 <div class="sectionbody">
 435 <p>Several options related to the interface with git can be configured
 436 via environment options.</p>
 437 <h3>Repository references</h3>
 438 <p>Commits that are referenced by tags and branch heads will be marked
 439 by the reference name surrounded by <em>[</em> and <em>]</em>:</p>
 440 <div class="literalblock">
 441 <div class="content">
 442 <pre><tt>2006-03-26 19:42 Petr Baudis         | [cogito-0.17.1] Cogito 0.17.1</tt></pre>
 443 </div></div>
 444 <p>If you want to filter out certain directories under <tt>.git/refs/</tt>, say
 445 <tt>tmp</tt> you can do it by setting the following variable:</p>
 446 <div class="literalblock">
 447 <div class="content">
 448 <pre><tt>$ TIG_LS_REMOTE="git ls-remote . | sed /\/tmp\//d" tig</tt></pre>
 449 </div></div>
 450 <p>Or set the variable permanently in your environment.</p>
 451 <dl>
 452 <dt>
 453 TIG_LS_REMOTE
 454 </dt>
 455 <dd>
 456 <p>
 457         Set command for retrieving all repository references. The command
 458         should output data in the same format as git-ls-remote(1).
 459 </p>
 460 </dd>
 461 </dl>
 462 <h3><a id="view-commands"></a>View commands</h3>
 463 <p>It is possible to alter which commands are used for the different views.
 464 If for example you prefer commits in the main view to be sorted by date
 465 and only show 500 commits, use:</p>
 466 <div class="literalblock">
 467 <div class="content">
 468 <pre><tt>$ TIG_MAIN_CMD="git log --date-order -n500 --pretty=raw %s" tig</tt></pre>
 469 </div></div>
 470 <p>Or set the variable permanently in your environment.</p>
 471 <p>Notice, how <tt>%s</tt> is used to specify the commit reference. There can
 472 be a maximum of 5 <tt>%s</tt> ref specifications.</p>
 473 <dl>
 474 <dt>
 475 TIG_DIFF_CMD
 476 </dt>
 477 <dd>
 478 <p>
 479         The command used for the diff view. By default, git show is used
 480         as a backend.
 481 </p>
 482 </dd>
 483 <dt>
 484 TIG_LOG_CMD
 485 </dt>
 486 <dd>
 487 <p>
 488         The command used for the log view. If you prefer to have both
 489         author and committer shown in the log view be sure to pass
 490         <tt>--pretty=fuller</tt> to git log.
 491 </p>
 492 </dd>
 493 <dt>
 494 TIG_MAIN_CMD
 495 </dt>
 496 <dd>
 497 <p>
 498         The command used for the main view. Note, you must always specify
 499         the option: <tt>--pretty=raw</tt> since the main view parser expects to
 500         read that format.
 501 </p>
 502 </dd>
 503 </dl>
 504 </div>
 505 <h2>The viewer</h2>
 506 <div class="sectionbody">
 507 <p>The display consists of a status window on the last line of the screen and
 508 one or more views. The default is to only show one view at the time but it
 509 is possible to split both the main and log view to also show the commit
 510 diff.</p>
 511 <p>If you are in the log view and press <em>Enter</em> when the current line is a
 512 commit line, such as:</p>
 513 <div class="literalblock">
 514 <div class="content">
 515 <pre><tt>commit 4d55caff4cc89335192f3e566004b4ceef572521</tt></pre>
 516 </div></div>
 517 <p>You will split the view so that the log view is displayed in the top window
 518 and the diff view in the bottom window. You can switch between the two
 519 views by pressing <em>Tab</em>. To maximize the log view again, simply press <em>l</em>.</p>
 520 <h3>Current head and commit ID</h3>
 521 <p>The viewer keeps track of both what head and commit ID you are currently
 522 viewing. The commit ID will follow the cursor line and change everytime time
 523 you highlight a different commit. Whenever you reopen the diff view it
 524 will be reloaded, if the commit ID changed.</p>
 525 <p>The head ID is used when opening the main and log view to indicate from
 526 what revision to show history.</p>
 527 <h3>Views</h3>
 528 <p>tig(1) presents various <em>views</em> of a repository. Each view is based on output
 529 from an external command, most often <em>git log</em>, <em>git diff</em>, or <em>git show</em>.</p>
 530 <dl>
 531 <dt>
 532 The main view
 533 </dt>
 534 <dd>
 535 <p>
 536         Is the default view, and it shows a one line summary of each commit
 537         in the chosen list of revisions. The summary includes commit date,
 538         author, and the first line of the log message. Additionally, any
 539         repository references, such as tags, will be shown.
 540 </p>
 541 </dd>
 542 <dt>
 543 The log view
 544 </dt>
 545 <dd>
 546 <p>
 547         Presents a more rich view of the revision log showing the whole log
 548         message and the diffstat.
 549 </p>
 550 </dd>
 551 <dt>
 552 The diff view
 553 </dt>
 554 <dd>
 555 <p>
 556         Shows either the diff of the current working tree, that is, what
 557         has changed since the last commit, or the commit diff complete
 558         with log message, diffstat and diff.
 559 </p>
 560 </dd>
 561 <dt>
 562 The pager view
 563 </dt>
 564 <dd>
 565 <p>
 566         Is used for displaying both input from stdin and output from git
 567         commands entered in the internal prompt.
 568 </p>
 569 </dd>
 570 <dt>
 571 The help view
 572 </dt>
 573 <dd>
 574 <p>
 575         Displays the information from the tig(1) man page. For the help view
 576         to work you need to have the tig(1) man page installed.
 577 </p>
 578 </dd>
 579 </dl>
 580 <h3>Title windows</h3>
 581 <p>Each view has a title window which shows the name of the view, current
 582 commit ID if available, and where the view is positioned:</p>
 583 <div class="literalblock">
 584 <div class="content">
 585 <pre><tt>[main] c622eefaa485995320bc743431bae0d497b1d875 - commit 1 of 61 (1%)</tt></pre>
 586 </div></div>
 587 <p>By default, the title of the current view is highlighted using bold font.</p>
 588 </div>
 589 <h2>KEYS</h2>

 831         Open prompt. This allows you to specify what git command

 834 <div class="literalblock">
 835 <div class="content">
 836 <pre><tt>:log -p</tt></pre>
 837 </div></div>

 841 <h2><a id="refspec"></a>Revision specification</h2>
 842 <div class="sectionbody">
 843 <p>This section describes various ways to specify what revisions to display
 844 or otherwise limit the view to. tig(1) does not itself parse the described
 845 revision options so refer to the relevant git man pages for futher
 846 information. Relevant man pages besides git-log(1) are git-diff(1) and
 847 git-rev-list(1).</p>
 848 <p>You can tune the interaction with git by making use of the options
 849 explained in this section. For example, by configuring the environment
 850 variables described in the  <a href="#view-commands">"View commands"</a> section.</p>
 851 <h3>Limit by path name</h3>
 852 <p>If you are interested only in those revisions that made changes to a
 853 specific file (or even several files) list the files like this:</p>
 854 <div class="literalblock">
 855 <div class="content">
 856 <pre><tt>$ tig log Makefile README</tt></pre>
 857 </div></div>
 858 <p>To avoid ambiguity with repository references such as tag name, be sure
 859 to separate file names from other git options using "--". So if you
 860 have a file named <em>master</em> it will clash with the reference named
 861 <em>master</em>, and thus you will have to use:</p>
 862 <div class="literalblock">
 863 <div class="content">
 864 <pre><tt>$ tig log -- master</tt></pre>
 865 </div></div>
 866 <div class="admonitionblock">
 867 <table><tr>
 868 <td class="icon">
 869 <div class="title">Note</div>
 870 </td>
 871 <td class="content">For the main view, avoiding ambiguity will in some cases require
 872 you to specify two "--" options. The first will make tig(1) stop
 873 option processing and the latter will be passed to git log.</td>
 874 </tr></table>
 875 </div>
 876 <h3>Limit by date or number</h3>
 877 <p>To speed up interaction with git, you can limit the amount of commits
 878 to show both for the log and main view. Either limit by date using
 879 e.g. <tt>--since=1.month</tt> or limit by the number of commits using <tt>-n400</tt>.</p>
 880 <p>If you are only interested in changed that happened between two dates
 881 you can use:</p>
 882 <div class="literalblock">
 883 <div class="content">
 884 <pre><tt>$ tig -- --after="May 5th" --before="2006-05-16 15:44"</tt></pre>
 885 </div></div>
 886 <div class="admonitionblock">
 887 <table><tr>
 888 <td class="icon">
 889 <div class="title">Note</div>
 890 </td>
 891 <td class="content">If you want to avoid having to quote dates containing spaces you
 892 can use "." instead, e.g. <tt>--after=May.5th</tt>.</td>
 893 </tr></table>
 894 </div>
 895 <h3>Limiting by commit ranges</h3>
 896 <p>Alternatively, commits can be limited to a specific range, such as
 897 "all commits between <em>tag-1.0</em> and <em>tag-2.0</em>". For example:</p>
 898 <div class="literalblock">
 899 <div class="content">
 900 <pre><tt>$ tig log tag-1.0..tag-2.0</tt></pre>
 901 </div></div>
 902 <p>This way of commit limiting makes it trivial to only browse the commits
 903 which haven't been pushed to a remote branch. Assuming <em>origin</em> is your
 904 upstream remote branch, using:</p>
 905 <div class="literalblock">
 906 <div class="content">
 907 <pre><tt>$ tig log origin..HEAD</tt></pre>
 908 </div></div>
 909 <p>will list what will be pushed to the remote branch. Optionally, the ending
 910 <em>HEAD</em> can be left out since it is implied.</p>
 911 <h3>Limiting by reachability</h3>
 912 <p>Git interprets the range specifier "tag-1.0..tag-2.0" as
 913 "all commits reachable from <em>tag-2.0</em> but not from <em>tag-1.0</em>".
 914 Where reachability refers to what commits are ancestors (or part of the
 915 history) of the branch or tagged revision in question.</p>
 916 <p>If you prefer to specify which commit to preview in this way use the
 917 following:</p>
 918 <div class="literalblock">
 919 <div class="content">
 920 <pre><tt>$ tig log tag-2.0 ^tag-1.0</tt></pre>
 921 </div></div>
 922 <p>You can think of <em>^</em> as a negation operator. Using this alternate syntax,
 923 it is possible to further prune commits by specifying multiple branch
 924 cut offs.</p>
 925 <h3>Combining revisions specification</h3>
 926 <p>Revisions options can to some degree be combined, which makes it possible
 927 to say "show at most 20 commits from within the last month that changed
 928 files under the Documentation/ directory."</p>
 929 <div class="literalblock">
 930 <div class="content">
 931 <pre><tt>$ tig -- --since=1.month -n20 -- Documentation/</tt></pre>
 932 </div></div>
 933 <h3>Examining all repository references</h3>
 934 <p>In some cases, it can be useful to query changes across all references
 935 in a repository. An example is to ask "did any line of development in
 936 this repository change a particular file within the last week". This
 937 can be accomplished using:</p>
 938 <div class="literalblock">
 939 <div class="content">
 940 <pre><tt>$ tig -- --all --since=1.week -- Makefile</tt></pre>
 941 </div></div>
 942 </div>

 945 <p>Known bugs and problems:</p>
 946 <ul>
 947 <li>
 948 <p>
 949 In it's current state tig is pretty much UTF-8 only.
 950 </p>
 951 </li>
 952 <li>
 953 <p>
 954 If the screen width is very small the main view can draw
 955 outside the current view causing bad wrapping. Same goes
 956 for title and status windows.
