21 | * DESCRIPTION | |
22 | * ----------- | |
6706b2ba JF |
23 | * Browse changes in a git repository. Additionally, tig(1) can also act |
24 | * as a pager for output of various git commands. | |
25 | * | |
26 | * Commit limiting | |
27 | * ~~~~~~~~~~~~~~~ | |
28 | * To speed up interaction with git, you can limit the amount of commits | |
29 | * to show both for the log and main view. Either limit by date using | |
30 | * e.g. `--since=1.month` or limit by the number of commits using `-n400`. | |
31 | * | |
32 | * Alternatively, commits can be limited to a specific range, such as | |
33 | * "all commits between tag-1.0 and tag-2.0". For example: | |
34 | * | |
35 | * $ tig log tag-1.0..tag-2.0 | |
36 | * | |
37 | * Git interprets this as "all commits reachable from commit-2 | |
38 | * but not from commit-1". The above can also be written: | |
39 | * | |
40 | * $ tig log tag-2.0 ^tag-1.0 | |
41 | * | |
42 | * You can think of '^' as a negator. Using this alternate syntax, | |
43 | * it is possible to furthur prune commits by specifying multiple | |
44 | * negators. | |
45 | * | |
46 | * This way of commit limiting makes it trivial to only browse the commit | |
47 | * which hasn't been pushed to a remote branch. Assuming origin is your | |
48 | * upstream remote branch, using: | |
49 | * | |
50 | * $ tig log origin..HEAD | |
51 | * | |
52 | * Optionally, with "HEAD" left out, will list what will be pushed to | |
53 | * the remote branch. | |
54 | * | |
55 | * See the section on environment variables, on how to further tune the | |
56 | * interaction with git. | |

705 | * ~~~~~~~~~~~~~ | |
1ba2ae4b | 706 | * It is possible to alter which commands are used for the different views. |
6706b2ba JF |
707 | * If for example you prefer commits in the main view to be sorted by date |

715 | * be a maximum of 5 `%s` ref specifications. | |
716 | * | |
717 | * TIG_DIFF_CMD:: | |
718 | * The command used for the diff view. By default, git show is used | |
719 | * as a backend. | |
720 | * | |
721 | * TIG_LOG_CMD:: | |
6706b2ba JF |
722 | * The command used for the log view. If you prefer to have both |
723 | * author and committer shown in the log view be sure to pass | |
724 | * `--pretty=fuller` to git log. | |

726 | * TIG_MAIN_CMD:: | |
727 | * The command used for the main view. Note, you must always specify | |
