gitで変更箇所を文字単位で表示

gitに同梱のdiff-highlightを使うことで、行単位から文字単位で変更を表示できる。

diff-highlightへPATHを通す。

Homebrewでgitを入れている場合

zsh,bashの場合

Intel Mac

$ export PATH=$PATH:/usr/local/share/git-core/contrib/diff-highlight

Apple Silicon

$ export PATH=$PATH:/opt/homebrew/opt/git/share/git-core/contrib/diff-highlight

fishの場合

Intel Mac

$ set -x PATH $PATH /usr/local/share/git-core/contrib/diff-highlight

Apple Silicon

$ set -x PATH $PATH /opt/homebrew/opt/git/share/git-core/contrib/diff-highlight

.gitconfigに設定を追加する

~/.gitconfig

log = diff-highlight | less
show = diff-highlight | less
diff = diff-highlig | less

結果

$ git diff Gemfile

便利。
