Replace branch log with basic CLI graph

[jelaniwoods]

Problem

I was thinking as a stopgap until we figure out some sort of JS graphing library to display the git graph, should we go back to my old hack of displaying the output of git sla at the bottom of /git? I feel like the tree view (with all the branches unified) is essential

The downside is that we'd have to install the command-line tools that the old web_git depended on

git sla being an alias of git log --oneline --decorate --graph --all

Solution

Until it becomes feasible to draw the graph with the git gem, capture the output of the graph from the command line and display it below the commit form.

To test

1. Add gem to Gemfile

gem "web_git", git: "https://github.com/firstdraft/web_git", branch: "jw-basic-cli-graph"

2. Run install command

rails g web_git:install

3. Run rails s
4. Visit /git

Wow, this is great. I love that it retains the benefit of clickable SHAs.

LGTM 🚢
