Sometimes, though, when an old line and a new line are very +similar, it's hard to immediately see the difference. + +You can use "--color-words" to highlight only the changed portions of +lines. However, this can often be hard to read for code, as it loses +the line structure, and you end up with oddly formatted bits. + +Instead, this script post-processes the line-oriented diff, finds pairs +of lines, and highlights the differing segments. It's currently very +simple and stupid about doing these tasks. In particular: + + 1. It will only highlight a pair of lines if they are the only two + lines in a hunk. It could instead try to match up "before" and + "after" lines for a given hunk into pairs of similar lines. + However, this may end up visually distracting, as the paired + lines would have other highlighted lines in between them. And in + practice, the lines which most need attention called to their + small, hard-to-see changes are touching only a single line. + + 2. It will find the common prefix and suffix of two lines, and + consider everything in the middle to be "different". It could + instead do a real diff of the characters between the two lines and + find common subsequences. However, the point of the highlight is to + call attention to a certain area. Even if some small subset of the + highlighted area actually didn't change, that's OK. In practice it + ends up being more readable to just have a single blob on the line + showing the interesting bit. + +The goal of the script is therefore not to be exact about highlighting +changes, but to call attention to areas of interest without being +visually distracting. Non-diff lines and existing diff coloration is +preserved; the intent is that the output should look exactly the same as +the input, except for the occasional highlight. + +Use +--- + +You can try out the diff-highlight program with: + +--------------------------------------------- +git log -p --color | /path/to/diff-highlight +--------------------------------------------- + +If you want to use it all the time, drop it in your $PATH and put the +following in your git configuration: + +--------------------------------------------- +[pager] + log = diff-highlight | less + show = diff-highlight | less + diff = diff-highlight | less +--------------------------------------------- diff --git a/contrib/diff-highlight/diff-highlight b/contrib/diff-highlight/diff-highlight new file mode 100755 index 0000000000..d8938982e4 --- /dev/null +++ b/contrib/diff-highlight/diff-highlight @@ -0,0 +1,124 @@ +#!/usr/bin/perl + +# Highlight by reversing foreground and background.

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). diff --git a/contrib/git-jump/git-jump b/contrib/git-jump/git-jump new file mode 100755 index 0000000000..a33674e47a --- /dev/null +++ b/contrib/git-jump/git-jump @@ -0,0 +1,69 @@ +#!/bin/sh + +usage() { + cat <<\EOF +usage: git jump <mode> [<args>] + +Jump to interesting elements in an editor. +The <mode> parameter is one of: + +diff: elements are diff hunks.
