 262 <h1>The tig Manual</h1>
 263 <span id="author">Jonas Fonseca</span><br />
 264 <span id="email"><tt>&lt;<a href="mailto:fonseca@diku.dk">fonseca@diku.dk</a>&gt;</tt></span><br />
 265 </div>
 266 <div id="preamble">
 267 <div class="sectionbody">
 268 <p>This is the manual for tig, the ncurses-based text-mode interface for git.
 269 Tig allows you to browse changes in a git repository and can additionally act
 270 as a pager for output of various git commands. When used as a pager, it will
 271 display input from stdin and colorize it.</p>
 272 <p>When browsing repositories, tig uses the underlying git commands to present
 273 the user with various views, such as summarized commit log and showing the
 274 commit with the log message, diffstat, and the diff.</p>
 275 </div>
 276 </div>
 277 <h2>Calling Conventions</h2>
 278 <div class="sectionbody">
 279 <h3>Pager Mode</h3>
 280 <p>If stdin is a pipe, any log or diff options will be ignored and the pager view
 281 will be opened loading data from stdin. The pager mode can be used for
 282 colorizing output from various git commands.</p>
 283 <p>Example on how to colorize the output of git-show(1):</p>
 284 <div class="literalblock">
 285 <div class="content">
 286 <pre><tt>$ git show | tig</tt></pre>
 287 </div></div>
 288 <h3>Git Command Options</h3>
 289 <p>All git command options specified on the command line will be passed to the
 290 given command and all will be shell quoted before they are passed to the
 291 shell.</p>
 292 <div class="admonitionblock">
 293 <table><tr>
 294 <td class="icon">
 295 <div class="title">Note</div>
 296 </td>
 297 <td class="content">If you specify options for the main view, you should not use the
 298 <tt>&#8212;pretty</tt> option as this option will be set automatically to the format
 299 expected by the main view.</td>
 300 </tr></table>
 301 </div>
 302 <p>Example on how to open the log view and show both author and committer
 303 information:</p>
 304 <div class="literalblock">
 305 <div class="content">
 306 <pre><tt>$ tig log --pretty=fuller</tt></pre>
 307 </div></div>
 308 <p>See the <a href="#refspec">"Specifying revisions"</a> section below for an introduction
 309 to revision options supported by the git commands. For details on specific git
 310 command options, refer to the man page of the command in question.</p>
 311 </div>
 312 <h2>Environment Variables</h2>
 313 <div class="sectionbody">
 314 <p>Several options related to the interface with git can be configured via
 315 environment options.</p>
 316 <h3>Repository References</h3>
 317 <p>Commits that are referenced by tags and branch heads will be marked by the
 318 reference name surrounded by <em>[</em> and <em>]</em>:</p>
 319 <div class="literalblock">
 320 <div class="content">
 321 <pre><tt>2006-03-26 19:42 Petr Baudis         | [cogito-0.17.1] Cogito 0.17.1</tt></pre>
 322 </div></div>
 323 <p>If you want to filter out certain directories under <tt>.git/refs/</tt>, say <tt>tmp</tt>
 324 you can do it by setting the following variable:</p>
 325 <div class="literalblock">
 326 <div class="content">
 327 <pre><tt>$ TIG_LS_REMOTE="git ls-remote . | sed /\/tmp\//d" tig</tt></pre>
 328 </div></div>
 329 <p>Or set the variable permanently in your environment.</p>
 330 <dl>
 331 <dt>
 332 TIG_LS_REMOTE
 333 </dt>
 334 <dd>
 335 <p>
 336         Set command for retrieving all repository references. The command
 337         should output data in the same format as git-ls-remote(1).
 338 </p>
 339 </dd>
 340 </dl>
 341 <h3><a id="history-commands"></a>History Commands</h3>
 342 <p>It is possible to alter which commands are used for the different views.  If
 343 for example you prefer commits in the main view to be sorted by date and only
 344 show 500 commits, use:</p>
 345 <div class="literalblock">
 346 <div class="content">
 347 <pre><tt>$ TIG_MAIN_CMD="git log --date-order -n500 --pretty=raw %s" tig</tt></pre>
 348 </div></div>
 349 <p>Or set the variable permanently in your environment.</p>
 350 <p>Notice, how <tt>%s</tt> is used to specify the commit reference. There can be a
 351 maximum of 5 <tt>%s</tt> ref specifications.</p>
 352 <dl>
 353 <dt>
 354 TIG_DIFF_CMD
 355 </dt>
 356 <dd>
 357 <p>
 358         The command used for the diff view. By default, git show is used
 359         as a backend.
 360 </p>
 361 </dd>
 362 <dt>
 363 TIG_LOG_CMD
 364 </dt>
 365 <dd>
 366 <p>
 367         The command used for the log view. If you prefer to have both
 368         author and committer shown in the log view be sure to pass
 369         <tt>&#8212;pretty=fuller</tt> to git log.
 370 </p>
 371 </dd>
 372 <dt>
 373 TIG_MAIN_CMD
 374 </dt>
 375 <dd>
 376 <p>
 377         The command used for the main view. Note, you must always specify
 378         the option: <tt>&#8212;pretty=raw</tt> since the main view parser expects to
 379         read that format.
 380 </p>
 381 </dd>
 382 </dl>
 383 </div>
 384 <h2>The Viewer</h2>
 385 <div class="sectionbody">
 386 <p>The display consists of a status window on the last line of the screen and one
 387 or more views. The default is to only show one view at the time but it is
 388 possible to split both the main and log view to also show the commit diff.</p>
 389 <p>If you are in the log view and press <em>Enter</em> when the current line is a commit
 390 line, such as:</p>
 391 <div class="literalblock">
 392 <div class="content">
 393 <pre><tt>commit 4d55caff4cc89335192f3e566004b4ceef572521</tt></pre>
 394 </div></div>
 395 <p>You will split the view so that the log view is displayed in the top window
 396 and the diff view in the bottom window. You can switch between the two views
 397 by pressing <em>Tab</em>. To maximize the log view again, simply press <em>l</em>.</p>
 398 <h3>Current Head and Commit ID</h3>
 399 <p>The viewer keeps track of both what head and commit ID you are currently
 400 viewing. The commit ID will follow the cursor line and change everytime time
 401 you highlight a different commit. Whenever you reopen the diff view it will be
 402 reloaded, if the commit ID changed.</p>
 403 <p>The head ID is used when opening the main and log view to indicate from what
 404 revision to show history.</p>
 405 <h3>Views</h3>
 406 <p>tig(1) presents various <em>views</em> of a repository. Each view is based on output
 407 from an external command, most often <em>git log</em>, <em>git diff</em>, or <em>git show</em>.</p>
 408 <dl>
 409 <dt>
 410 The main view
 411 </dt>
 412 <dd>
 413 <p>
 414         Is the default view, and it shows a one line summary of each commit
 415         in the chosen list of revisions. The summary includes commit date,
 416         author, and the first line of the log message. Additionally, any
 417         repository references, such as tags, will be shown.
 418 </p>
 419 </dd>
 420 <dt>
 421 The log view
 422 </dt>
 423 <dd>
 424 <p>
 425         Presents a more rich view of the revision log showing the whole log
 426         message and the diffstat.
 427 </p>
 428 </dd>
 429 <dt>
 430 The diff view
 431 </dt>
 432 <dd>
 433 <p>
 434         Shows either the diff of the current working tree, that is, what
 435         has changed since the last commit, or the commit diff complete
 436         with log message, diffstat and diff.
 437 </p>
 438 </dd>
 439 <dt>
 440 The pager view
 441 </dt>
 442 <dd>
 443 <p>
 444         Is used for displaying both input from stdin and output from git
 445         commands entered in the internal prompt.
 446 </p>
 447 </dd>
 448 <dt>
 449 The help view
 450 </dt>
 451 <dd>
 452 <p>
 453         Displays the information from the tig(1) man page. For the help view
 454         to work you need to have the tig(1) man page installed.
 455 </p>
 456 </dd>
 457 </dl>
 458 <h3>Title Windows</h3>
 459 <p>Each view has a title window which shows the name of the view, current commit
 460 ID if available, and where the view is positioned:</p>
 461 <div class="literalblock">
 462 <div class="content">
 463 <pre><tt>[main] c622eefaa485995320bc743431bae0d497b1d875 - commit 1 of 61 (1%)</tt></pre>
 464 </div></div>
 465 <p>By default, the title of the current view is highlighted using bold font.  For
 466 long loading views (taking over 3 seconds) the time since loading started will
 467 be appended:</p>
 468 <div class="literalblock">
 469 <div class="content">
 470 <pre><tt>[main] 77d9e40fbcea3238015aea403e06f61542df9a31 - commit 1 of 779 (0%) 5s</tt></pre>

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

 719 <div class="content">

 725 <h2><a id="refspec"></a>Revision Specification</h2>
 726 <div class="sectionbody">
 727 <p>This section describes various ways to specify what revisions to display or
 728 otherwise limit the view to. tig(1) does not itself parse the described
 729 revision options so refer to the relevant git man pages for futher
 730 information. Relevant man pages besides git-log(1) are git-diff(1) and
 731 git-rev-list(1).</p>
 732 <p>You can tune the interaction with git by making use of the options explained
 733 in this section. For example, by configuring the environment variables
 734 described in the  <a href="#history-commands">"History commands"</a> section.</p>
 735 <h3>Limit by Path Name</h3>
 736 <p>If you are interested only in those revisions that made changes to a specific
 737 file (or even several files) list the files like this:</p>
 738 <div class="literalblock">
 739 <div class="content">
 740 <pre><tt>$ tig log Makefile README</tt></pre>
 741 </div></div>
 742 <p>To avoid ambiguity with repository references such as tag name, be sure to
 743 separate file names from other git options using "--". So if you have a file
 744 named <em>master</em> it will clash with the reference named <em>master</em>, and thus you
 745 will have to use:</p>
 746 <div class="literalblock">
 747 <div class="content">
 748 <pre><tt>$ tig log -- master</tt></pre>
 749 </div></div>
 750 <div class="admonitionblock">
 751 <table><tr>
 752 <td class="icon">
 753 <div class="title">Note</div>
 754 </td>
 755 <td class="content">For the main view, avoiding ambiguity will in some cases require you to
 756 specify two "--" options. The first will make tig(1) stop option processing
 757 and the latter will be passed to git log.</td>
 758 </tr></table>
 759 </div>
 760 <h3>Limit by Date or Number</h3>
 761 <p>To speed up interaction with git, you can limit the amount of commits to show
 762 both for the log and main view. Either limit by date using e.g.
 763 <tt>&#8212;since=1.month</tt> or limit by the number of commits using <tt>-n400</tt>.</p>
 764 <p>If you are only interested in changed that happened between two dates you can
 765 use:</p>
 766 <div class="literalblock">
 767 <div class="content">
 768 <pre><tt>$ tig -- --after="May 5th" --before="2006-05-16 15:44"</tt></pre>
 769 </div></div>
 770 <div class="admonitionblock">
 771 <table><tr>
 772 <td class="icon">
 773 <div class="title">Note</div>
 774 </td>
 775 <td class="content">If you want to avoid having to quote dates containing spaces you can use
 776 "." instead, e.g. <tt>&#8212;after=May.5th</tt>.</td>
 777 </tr></table>
 778 </div>
 779 <h3>Limiting by Commit Ranges</h3>
 780 <p>Alternatively, commits can be limited to a specific range, such as "all
 781 commits between <em>tag-1.0</em> and <em>tag-2.0</em>". For example:</p>
 782 <div class="literalblock">
 783 <div class="content">
 784 <pre><tt>$ tig log tag-1.0..tag-2.0</tt></pre>
 785 </div></div>
 786 <p>This way of commit limiting makes it trivial to only browse the commits which
 787 haven't been pushed to a remote branch. Assuming <em>origin</em> is your upstream
 788 remote branch, using:</p>
 789 <div class="literalblock">
 790 <div class="content">
 791 <pre><tt>$ tig log origin..HEAD</tt></pre>
 792 </div></div>
 793 <p>will list what will be pushed to the remote branch. Optionally, the ending
 794 <em>HEAD</em> can be left out since it is implied.</p>
 795 <h3>Limiting by Reachability</h3>
 796 <p>Git interprets the range specifier "tag-1.0..tag-2.0" as "all commits
 797 reachable from <em>tag-2.0</em> but not from <em>tag-1.0</em>".  Where reachability refers
 798 to what commits are ancestors (or part of the history) of the branch or tagged
 799 revision in question.</p>
 800 <p>If you prefer to specify which commit to preview in this way use the
 801 following:</p>
 802 <div class="literalblock">
 803 <div class="content">
 804 <pre><tt>$ tig log tag-2.0 ^tag-1.0</tt></pre>
 805 </div></div>
 806 <p>You can think of <em>^</em> as a negation operator. Using this alternate syntax, it
 807 is possible to further prune commits by specifying multiple branch cut offs.</p>
 808 <h3>Combining Revisions Specification</h3>
 809 <p>Revisions options can to some degree be combined, which makes it possible to
 810 say "show at most 20 commits from within the last month that changed files
 811 under the Documentation/ directory."</p>
 812 <div class="literalblock">
 813 <div class="content">
 814 <pre><tt>$ tig -- --since=1.month -n20 -- Documentation/</tt></pre>
 815 </div></div>
 816 <h3>Examining All Repository References</h3>
 817 <p>In some cases, it can be useful to query changes across all references in a
 818 repository. An example is to ask "did any line of development in this
 819 repository change a particular file within the last week". This can be
 820 accomplished using:</p>
 821 <div class="literalblock">
 822 <div class="content">
 823 <pre><tt>$ tig -- --all --since=1.week -- Makefile</tt></pre>
 824 </div></div>
 825 </div>
 826 <h2>BUGS</h2>
 827 <div class="sectionbody">
 828 <p>Known bugs and problems:</p>
 829 <ul>
 830 <li>
 831 <p>
 832 In it's current state tig is pretty much UTF-8 only.
 833 </p>
 834 </li>
 835 <li>
 836 <p>
 837 If the screen width is very small the main view can draw
 838    outside the current view causing bad wrapping. Same goes
 839    for title and status windows.
 840 </p>
 841 </li>
 842 <li>
 843 <p>
 844 The cursor can wrap-around on the last line and cause the
 845    window to scroll.
 846 </p>
 847 </li>

 849 <p>
 850 The prompt doesn't work while loading.
