Git: Pretty Log Printing
Git commands have many, many options for controlling what they do, and the command git log is no different.
One StackOverflow:pretty-git-logs thread has some suggested commands that create nice-looking textual graphs of git logs, and show the power of the commands.
One example is:
git log --graph --abbrev-commit --decorate --format=format:'%C(bold blue)%h%C(reset) - %C(green)(%ar)%C(reset) %C(black)%s%C(reset) %C(dim white)- %an%C(reset)%C(red)%d%C(reset)' --all
What does all that mean? I leave it to you to investigate, but you can run the command on your own repository and get an idea by looking at the output.
Use Your GitConfig for Complex Commands
You can create aliases in your local .gitconfig file that captures this and any complex git command that you want to use a lot. For example, you can have this in your .gitconfig:
[alias]
plog = log --graph --abbrev-commit --decorate --format=format:'%C(bold blue)%h%C(reset) - %C(green)(%ar)%C(reset) %C(black)%s%C(reset) %C(dim white)- %an%C(reset)%C(red)%d%C(reset)' --all
Then you can use the command git plog and this will do a log command with all of the options listed.
Other Resources
Just google pretty git logs or something like that and you can find lots of possibilities. Even python scripts and other tools to convert the textual output into actual graphs!
