4 Git-jump is a script for helping you jump to "interesting" parts of your
5 project in your editor. It works by outputting a set of interesting
6 spots in the "quickfix" format, which editors like vim can use as a
7 queue of places to visit (this feature is usually used to jump to errors
8 produced by a compiler). For example, given a diff like this:
10 ------------------------------------
11 diff --git a/foo.c b/foo.c
12 index a655540..5a59044 100644
17 - printf("hello word!\n");
18 + printf("hello world!\n");
20 -----------------------------------
22 git-jump will feed this to the editor:
24 -----------------------------------
25 foo.c:2: printf("hello word!\n");
26 -----------------------------------
28 Or, when running 'git jump grep', column numbers will also be emitted,
29 e.g. `git jump grep "hello"` would return:
31 -----------------------------------
32 foo.c:2:9: printf("hello word!\n");
33 -----------------------------------
35 Obviously this trivial case isn't that interesting; you could just open
36 `foo.c` yourself. But when you have many changes scattered across a
37 project, you can use the editor's support to "jump" from point to point.
39 Git-jump can generate four types of interesting lists:
41 1. The beginning of any diff hunks.
43 2. The beginning of any merge conflict markers.
45 3. Any grep matches, including the column of the first match on a
48 4. Any whitespace errors detected by `git diff --check`.
54 To use it, just drop git-jump in your PATH, and then invoke it like
57 --------------------------------------------------
58 # jump to changes not yet staged for commit
61 # jump to changes that are staged for commit; you can give
62 # arbitrary diff options
63 git jump diff --cached
65 # jump to merge conflicts
68 # documentation conflicts are hard; skip past them for now
69 git jump merge :^Documentation
71 # jump to all instances of foo_bar
74 # same as above, but case-insensitive; you can give
75 # arbitrary grep options
76 git jump grep -i foo_bar
78 # use the silver searcher for git jump grep
79 git config jump.grepCmd "ag --column"
80 --------------------------------------------------
82 You can use the optional argument '--stdout' to print the listing to
83 standard output instead of feeding it to the editor. You can use the
84 argument with M-x grep on Emacs:
86 --------------------------------------------------
87 # In Emacs, M-x grep and invoke "git jump --stdout <mode>"
88 M-x grep<RET>git jump --stdout diff<RET>
89 --------------------------------------------------
94 You can accomplish some of the same things with individual tools. For
95 example, you can use `git mergetool` to start vimdiff on each unmerged
96 file. `git jump merge` is for the vim-wielding luddite who just wants to
97 jump straight to the conflict text with no fanfare.
99 As of git v1.7.2, `git grep` knows the `--open-files-in-pager` option,
100 which does something similar to `git jump grep`. However, it is limited
101 to positioning the cursor to the correct line in only the first file,
102 leaving you to locate subsequent hits in that file or other files using
103 the editor or pager. By contrast, git-jump provides the editor with a
104 complete list of files, lines, and a column number for each match.
110 This script was written and tested with vim. Given that the quickfix
111 format is the same as what gcc produces, I expect other tools have a
112 similar feature for iterating through the list, but I know nothing about
115 The shell snippets to generate the quickfix lines will almost certainly
116 choke on filenames with exotic characters (like newlines).
121 Bug fixes, bug reports, and feature requests should be discussed on the
122 Git mailing list <git@vger.kernel.org>, and cc'd to the git-jump
123 maintainer, Jeff King <peff@peff.net>.
