 266 <h2>NAME</h2>
 267 <div class="sectionbody">
 268 <p>tig -
 269    text-mode interface for git
 270 </p>
 271 </div>
 272 </div>
 273 <h2>SYNOPSIS</h2>
 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]
 279 tig [options] diff [git diff options]
 280 tig [options] show [git show options]
 281 tig [options] &lt;    [git command output]</div></div>
 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>
 293 <h2>OPTIONS</h2>
 294 <div class="sectionbody">

 335 </p>
 336 </dd>
 337 <dt>
 338 --
 339 </dt>
 340 <dd>
 341 <p>
 342         End of tig(1) options. Useful when specifying command
 343         options for the main view. Example:
 344 </p>
 345 <div class="literalblock">
 346 <div class="content">
 347 <pre><tt>$ tig -- --since=1.month</tt></pre>
 348 </div></div>
 349 </dd>
 350 <dt>
 351 log [git log options]
 352 </dt>
 353 <dd>
 354 <p>
 355         Open log view using the given git log options.
 356 </p>
 357 </dd>
 358 <dt>
 359 diff [git diff options]
 360 </dt>
 361 <dd>
 362 <p>
 363         Open diff view using the given git diff options.
 364 </p>
 365 </dd>
 366 <dt>
 367 show [git show options]
 368 </dt>
 369 <dd>
 370 <p>
 371         Open diff view using the given git show options.
 372 </p>
 373 </dd>
 374 <dt>
 375 [git log options]
 376 </dt>
 377 <dd>
 378 <p>
 379         tig(1) will stop the option parsing when the first
 380         command line parameter not starting with "-" is
 381         encountered. All options including this one will be
 382         passed to git log when loading the main view.
 383         This makes it possible to say:
 384 </p>
 385 <div class="literalblock">
 386 <div class="content">
 387 <pre><tt>$ tig tag-1.0..HEAD</tt></pre>
 388 </div></div>
 389 </dd>
 390 </dl>
 391 <h3>Pager mode</h3>
 392 <p>If stdin is a pipe, any log or diff options will be ignored and the
 393 pager view will be opened loading data from stdin. The pager mode
 394 can be used for colorizing output from various git commands.</p>
 395 <p>Example on how to colorize the output of git-show(1):</p>
 396 <div class="literalblock">
 397 <div class="content">
 398 <pre><tt>$ git show | tig</tt></pre>
 399 </div></div>
 400 <h3>Git command options</h3>
 401 <p>All git command options specified on the command line will
 402 be passed to the given command and all will be shell quoted
 403 before they are passed to the shell.</p>
 404 <div class="admonitionblock">
 405 <table><tr>
 406 <td class="icon">
 407 <div class="title">Note</div>
 408 </td>
 409 <td class="content">If you specify options for the main view, you should
 410 not use the <tt>--pretty</tt> option as this option will be set
 411 automatically to the format expected by the main view.</td>
 412 </tr></table>
 413 </div>
 414 <p>Example on how to open the log view and show both author and
 415 committer information:</p>
 416 <div class="literalblock">
 417 <div class="content">
 418 <pre><tt>$ tig log --pretty=fuller</tt></pre>
 419 </div></div>
 420 <p>See the <a href="#refspec">"Specifying revisions"</a> section below
 421 for an introduction to revision options supported by the git
 422 commands. For details on specific git command options, refer
 423 to the man page of the command in question.</p>
 424 </div>
 425 <h2>ENVIRONMENT VARIABLES</h2>
 426 <div class="sectionbody">
 427 <p>Several options related to the interface with git can be configured
 428 via environment options.</p>
 429 <h3>Repository references</h3>
 430 <p>Commits that are referenced by tags and branch heads will be marked
 431 by the reference name surrounded by <em>[</em> and <em>]</em>:</p>
 432 <div class="literalblock">
 433 <div class="content">
 434 <pre><tt>2006-03-26 19:42 Petr Baudis         | [cogito-0.17.1] Cogito 0.17.1</tt></pre>
 435 </div></div>
 436 <p>If you want to filter out certain directories under <tt>.git/refs/</tt>, say
 437 <tt>tmp</tt> you can do it by setting the following variable:</p>
 438 <div class="literalblock">
 439 <div class="content">
 440 <pre><tt>$ TIG_LS_REMOTE="git ls-remote . | sed /\/tmp\//d" tig</tt></pre>
 441 </div></div>
 442 <p>Or set the variable permanently in your environment.</p>
 443 <dl>
 444 <dt>
 445 TIG_LS_REMOTE
 446 </dt>
 447 <dd>
 448 <p>
 449         Set command for retrieving all repository references. The command
 450         should output data in the same format as git-ls-remote(1).
 451 </p>
 452 </dd>
 453 </dl>
 454 <h3><a id="view-commands"></a>View commands</h3>
 455 <p>It is possible to alter which commands are used for the different views.
 456 If for example you prefer commits in the main view to be sorted by date
 457 and only show 500 commits, use:</p>
 458 <div class="literalblock">
 459 <div class="content">
 460 <pre><tt>$ TIG_MAIN_CMD="git log --date-order -n500 --pretty=raw %s" tig</tt></pre>
 461 </div></div>
 462 <p>Or set the variable permanently in your environment.</p>
 463 <p>Notice, how <tt>%s</tt> is used to specify the commit reference. There can
 464 be a maximum of 5 <tt>%s</tt> ref specifications.</p>
 465 <dl>
 466 <dt>
 467 TIG_DIFF_CMD
 468 </dt>
 469 <dd>
 470 <p>
 471         The command used for the diff view. By default, git show is used
 472         as a backend.
 473 </p>
 474 </dd>
 475 <dt>
 476 TIG_LOG_CMD
 477 </dt>
 478 <dd>
 479 <p>
 480         The command used for the log view. If you prefer to have both
 481         author and committer shown in the log view be sure to pass
 482         <tt>--pretty=fuller</tt> to git log.
 483 </p>
 484 </dd>
 485 <dt>
 486 TIG_MAIN_CMD
 487 </dt>
 488 <dd>
 489 <p>
 490         The command used for the main view. Note, you must always specify
 491         the option: <tt>--pretty=raw</tt> since the main view parser expects to
 492         read that format.
 493 </p>
 494 </dd>
 495 </dl>
 496 </div>
 497 <h2>The viewer</h2>
 498 <div class="sectionbody">
 499 <p>tig(1) presents various <em>views</em> of a repository. Each view is based on output
 500 from an external command, most often <em>git log</em>, <em>git diff</em>, or <em>git show</em>.</p>
 501 <dl>
 502 <dt>
 503 The main view
 504 </dt>
 505 <dd>
 506 <p>
 507         Is the default view, and it shows a one line summary of each commit
 508         in the chosen list of revision. The summary includes commit date,
 509         author, and the first line of the log message. Additionally, any
 510         repository references, such as tags, will be shown.
 511 </p>

 513 <dt>
 514 The log view
 515 </dt>
 516 <dd>
 517 <p>
 518         Presents a more rich view of the revision log showing the whole log
 519         message and the diffstat.
 520 </p>
 521 </dd>
 522 <dt>
 523 The diff view
 524 </dt>
 525 <dd>
 526 <p>
 527         Shows either the diff of the current working tree, that is, what
 528         has changed since the last commit, or the commit diff complete
 529         with log message, diffstat and diff.
 530 </p>

 532 <dt>
 533 The pager view
 534 </dt>
 535 <dd>
 536 <p>
 537         Is used for displaying both input from stdin and output from git
 538         commands entered in the internal prompt.
 539 </p>
 540 </dd>
 541 <dt>
 542 The help view
 543 </dt>
 544 <dd>
 545 <p>
 546         Displays the information from the tig(1) man page. For the help view
 547         to work you need to have the tig(1) man page installed.

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

 772 <div class="literalblock">
 773 <div class="content">
 774 <pre><tt>:log -p</tt></pre>
 775 </div></div>

 779 <h2><a id="refspec"></a>Revision specification</h2>
 780 <div class="sectionbody">
 781 <p>This section describes various ways to specify what revisions to display
 782 or otherwise limit the view to. tig(1) does not itself parse the described
 783 revision options so refer to the relevant git man pages for futher
 784 information. Relevant man pages besides git-log(1) are git-diff(1) and
 785 git-rev-list(1).</p>
 786 <p>You can tune the interaction with git by making use of the options
 787 explained in this section. For example, by configuring the environment
 788 variables described in the  <a href="#view-commands">"View commands"</a> section.</p>
 789 <h3>Limit by path name</h3>
 790 <p>If you are interested only in those revisions that made changes to a
 791 specific file (or even several files) list the files like this:</p>
 792 <div class="literalblock">
 793 <div class="content">
 794 <pre><tt>$ tig log Makefile</tt></pre>
 795 </div></div>
 796 <p>To avoid ambiguity with repository references such as tag name, be sure
 797 to separate file names from other git options using "--". So if you
 798 have a file named <em>master</em> it will clash with the reference named
 799 <em>master</em>, and thus you will have to use:</p>
 800 <div class="literalblock">
 801 <div class="content">
 802 <pre><tt>$ tag log -- master</tt></pre>
 803 </div></div>
 804 <div class="admonitionblock">
 805 <table><tr>
 806 <td class="icon">
 807 <div class="title">Note</div>
 808 </td>
 809 <td class="content">For the main view, avoiding ambiguity will in some cases require
 810 you to specify two "--" options. The first will make tig(1) stop
 811 option processing and the latter will be passed to git log.</td>
 812 </tr></table>
 813 </div>
 814 <h3>Limit by date or number</h3>
 815 <p>To speed up interaction with git, you can limit the amount of commits
 816 to show both for the log and main view. Either limit by date using
 817 e.g. <tt>--since=1.month</tt> or limit by the number of commits using <tt>-n400</tt>.</p>
 818 <p>If you are only interested in changed that happened between two dates
 819 you can use:</p>
 820 <div class="literalblock">
 821 <div class="content">
 822 <pre><tt>$ tig -- --after=may.5th --before=2006-05-16.15:44</tt></pre>
 823 </div></div>
 824 <div class="admonitionblock">
 825 <table><tr>
 826 <td class="icon">
 827 <div class="title">Note</div>
 828 </td>
 829 <td class="content">The dot (".") is used as a separator instead of a space to avoid
 830 having to quote the option value.</td>
 831 </tr></table>
 832 </div>
 833 <h3>Limiting by commit ranges</h3>
 834 <p>Alternatively, commits can be limited to a specific range, such as
 835 "all commits between <em>tag-1.0</em> and <em>tag-2.0</em>". For example:</p>
 836 <div class="literalblock">
 837 <div class="content">
 838 <pre><tt>$ tig log tag-1.0..tag-2.0</tt></pre>
 839 </div></div>
 840 <p>This way of commit limiting makes it trivial to only browse the commits
 841 which haven't been pushed to a remote branch. Assuming <em>origin</em> is your
 842 upstream remote branch, using:</p>
 843 <div class="literalblock">
 844 <div class="content">
 845 <pre><tt>$ tig log origin..HEAD</tt></pre>
 846 </div></div>
 847 <p>will list what will be pushed to the remote branch. Optionally, the ending
 848 <em>HEAD</em> can be left out since it is implied.</p>
 849 <h3>Limiting by reachability</h3>
 850 <p>Git interprets the range specifier "tag-1.0..tag-2.0" as
 851 "all commits reachable from <em>tag-2.0</em> but not from <em>tag-1.0</em>".
 852 Where reachability refers to what commits are ancestors (or part of the
 853 history) of the branch or tagged revision in question.</p>
 854 <p>If you prefer to specify which commit to preview in this way use the
 855 following:</p>
 856 <div class="literalblock">
 857 <div class="content">
 858 <pre><tt>$ tig log tag-2.0 ^tag-1.0</tt></pre>
 859 </div></div>
 860 <p>You can think of <em>^</em> as a negation operator. Using this alternate syntax,
 861 it is possible to further prune commits by specifying multiple branch
 862 cut offs.</p>
 863 <h3>Combining revisions specification</h3>
 864 <p>Revisions options can to some degree be combined, which makes it possible
 865 to say "show at most 20 commits from within the last month that changed
 866 files under the Documentation/ directory."</p>
 867 <div class="literalblock">
 868 <div class="content">
 869 <pre><tt>$ tig -- --since=1.month -n20 -- Documentation/</tt></pre>
 870 </div></div>
 871 <h3>Examining all repository references</h3>
 872 <p>In some cases, it can be useful to query changes across all references
 873 in a repository. An example is to ask "did any line of development in
 874 this repository change a particular file within the last week". This
 875 can be accomplished using:</p>
 876 <div class="literalblock">
 877 <div class="content">
 878 <pre><tt>$ tig -- --all --since=1.week -- Makefile</tt></pre>
 879 </div></div>
 880 </div>
