Reviewing changes involves reading diffs. Sometimes, a line-oriented presentation of changes is not precise enough, especially when changes involve long lines or very similar consecutive lines.
This program processes such diffs, and output them (in the console) with additional diff information on top of the unified diff format, using text attributes.
It works hunk by hunk, recomputing the diff on a word-by-word basis.
The current implementation uses Myers longest common subsequence algorithm.
diffr tries to be a well behaved unix program: it reads its input from stdin and writes to stdout.
cargo build --release
git show HEAD | path/to/diffr
Add the following sectionto your .gitconfig file:
[pager]
log = path/to/diffr | less -R
show = path/to/diffr | less -R
diff = path/to/diffr | less -R
This is improvement on the diff-highlight script distributed with git.
git itself provides both --word-diff and --color-words options to
several commands.
