diff-so-fancy makes your diffs human readable instead of machine readable. This helps improve code quality and helps you spot defects faster.

Vanilla git diff vs git and diff-so-fancy

๐ฆ Install
Simply copy the diff-so-fancy script from the latest Github release into your $PATH and you're done. Alternately to test development features you can clone this repo and then put the diff-so-fancy script (symlink will work) into your $PATH. The lib/ directory will need to be kept relative to the core script.
diff-so-fancy is also available from the NPM registry, brew, Fedora, in the Arch extra repo, and as ppa:aos for Debian/Ubuntu Linux.
Issues relating to packaging ("installation does not work", "version is out of date", etc.) should be directed to those packages' repositories/issue trackers where applicable.
โจ Usage
Git
Configure git to use diff-so-fancy for all diff output:
git config --global core.pager "diff-so-fancy | less --tabs=4 -RF"
git config --global interactive.diffFilter "diff-so-fancy --patch"
Diff
Use -u with diff for unified output, and pipe the output to diff-so-fancy:
diff -u file_a file_b | diff-so-fancy
We also support recursive mode with -r or --recursive
diff --recursive -u /path/folder_a /path/folder_b | diff-so-fancy
โ๏ธ Options

git config --bool --global diff-so-fancy.useUnicodeRuler false
rulerWidth
rulerWidth sets the width of the ruler lines. (Default: screen width)
git config --global diff-so-fancy.rulerWidth 80
shortHeaders
