========
|
|
|
|
Git-jump is a script for helping you jump to "interesting" parts of your
|
|
project in your editor. It works by outputting a set of interesting
|
|
spots in the "quickfix" format, which editors like vim can use as a
|
|
queue of places to visit (this feature is usually used to jump to errors
|
|
produced by a compiler). For example, given a diff like this:
|
|
|
|
------------------------------------
|
|
diff --git a/foo.c b/foo.c
|
|
index a655540..5a59044 100644
|
|
--- a/foo.c
|
|
+++ b/foo.c
|
|
@@ -1,3 +1,3 @@
|
|
int main(void) {
|
|
- printf("hello word!\n");
|
|
+ printf("hello world!\n");
|
|
}
|
|
-----------------------------------
|
|
|
|
git-jump will feed this to the editor:
|
|
|
|
-----------------------------------
|
|
foo.c:2: printf("hello word!\n");
|
|
-----------------------------------
|
|
|
|
Obviously this trivial case isn't that interesting; you could just open
|
|
`foo.c` yourself. But when you have many changes scattered across a
|
|
project, you can use the editor's support to "jump" from point to point.
|
|
|
|
Git-jump can generate three types of interesting lists:
|
|
|
|
1. The beginning of any diff hunks.
|
|
|
|
2. The beginning of any merge conflict markers.
|
|
|
|
3. Any grep matches.
|
|
|
|
|
|
Using git-jump
|
|
--------------
|
|
|
|
To use it, just drop git-jump in your PATH, and then invoke it like
|
|
this:
|
|
|
|
--------------------------------------------------
|
|
# jump to changes not yet staged for commit
|
|
git jump diff
|
|
|
|
# jump to changes that are staged for commit; you can give
|
|
# arbitrary diff options
|
|
git jump diff --cached
|
|
|
|
# jump to merge conflicts
|
|
git jump merge
|
|
|
|
# jump to all instances of foo_bar
|
|
git jump grep foo_bar
|
|
|
|
# same as above, but case-insensitive; you can give
|
|
# arbitrary grep options
|
|
git jump grep -i foo_bar
|
|
--------------------------------------------------
|
|
|

Related Programs

|
----------------

|
|
|
You can accomplish some of the same things with individual tools. For
|
|
example, you can use `git mergetool` to start vimdiff on each unmerged
|
|
file. `git jump merge` is for the vim-wielding luddite who just wants to
|
|
jump straight to the conflict text with no fanfare.
|
|
|
|
As of git v1.7.2, `git grep` knows the `--open-files-in-pager` option,
|
|
which does something similar to `git jump grep`. However, it is limited
|
|
to positioning the cursor to the correct line in only the first file,
|
|
leaving you to locate subsequent hits in that file or other files using
|
|
the editor or pager. By contrast, git-jump provides the editor with a
|
|
complete list of files and line numbers for each match.
|
|
|

|
Limitations
|
|
-----------
|
|
|
|
This scripts was written and tested with vim. Given that the quickfix
|
|
format is the same as what gcc produces, I expect emacs users have a
|
|
similar feature for iterating through the list, but I know nothing about
|
|
how to activate it.
|
|
|
|
The shell snippets to generate the quickfix lines will almost certainly
|
|
choke on filenames with exotic characters (like newlines).
