run git from within ruby script

Question

I want to dave or change a file with ruby, thats no problem. But this file is part of a git repository that needs to be commited after the change. How can I achieve that with the ruby script?

Answer 1

Call a shell command in your ruby script. There are lots of ways to execute a shell command in ruby. Backticks are one of them. Look at this Calling shell commands from Ruby for more.

`git commit -am "Committing from ruby script"`

Answer 2

Just use a Git library like ruby-git - establish the repo in a temp folder, pull the project into it, change the file, commit it, push it, and delete the repo. (Assuming it's a rare operation. If not, you should probably establish a permanent repo folder and just keep pulling, committing, and pushing it.)
