Directed Acyclic Graphs for Git

Last updated on 2023-05-11 2 min read

Make browsing your git repository’s history easier with git dag. Here’s how to set it up:

git config --global alias.dag 'log --graph --decorate --all --oneline'
git config --global color.ui true

dag stands for directed acyclic graph, i.e. a graph-based representation of a sequence of events. It makes your git history look like this:

$ git dag
