18 * tig [options] show [git show options]
19 * tig [options] < [git command output]
23 * Browse changes in a git repository. Additionally, tig(1) can also act
24 * as a pager for output of various git commands.
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`.
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:
35 * $ tig log tag-1.0..tag-2.0
37 * Git interprets this as "all commits reachable from commit-2
38 * but not from commit-1". The above can also be written:
40 * $ tig log tag-2.0 ^tag-1.0
42 * You can think of '^' as a negator. Using this alternate syntax,
43 * it is possible to furthur prune commits by specifying multiple
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:
50 * $ tig log origin..HEAD
52 * Optionally, with "HEAD" left out, will list what will be pushed to
55 * See the section on environment variables, on how to further tune the
56 * interaction with git.

676 * ENVIRONMENT VARIABLES
677 * ---------------------
678 * Several options related to the interface with git can be configured
679 * via environment options.
681 * Repository references
682 * ~~~~~~~~~~~~~~~~~~~~~
683 * Commits that are referenced by tags and branch heads will be marked
684 * by the reference name surrounded by '[' and ']':
686 * 2006-04-18 23:12 Jonas Fonseca | [tig-0.2] tig version 0.2
688 * If you want to filter out certain directories under `.git/refs/`, say
689 * `tmp` you can do it by setting the following variable:
691 * $ TIG_LS_REMOTE="git ls-remote . | sed /\/tmp\//d" tig
693 * Or set the variable permanently in your environment.
696 * Set command for retrieving all repository references. The command
697 * should output data in the same format as git-ls-remote(1).
700 #define TIG_LS_REMOTE \
706 * It is possible to alter which commands are used for the different views.
707 * If for example you prefer commits in the main view to be sorted by date
708 * and only show 500 commits, use:
710 * $ TIG_MAIN_CMD="git log --date-order -n500 --pretty=raw %s" tig
712 * Or set the variable permanently in your environment.
714 * Notice, how `%s` is used to specify the commit reference. There can
715 * be a maximum of 5 `%s` ref specifications.
718 * The command used for the diff view. By default, git show is used
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.
