Good times with git

[Permalink]     blog git

Having relatively recently moved to using git for version control, I've been thoroughly loving it :)

(By the way, I thoroughly recommend this document for getting to grips with git)

I don't know how other people work but in my place of work (at least on the project I'm currently working on ), we're using a system of one branch per major version, a branch for testing, and a branch for each developer. That doesn't preclude other branches of course, I frequently create local branches for new features or other things which are liable to break things.

This system gives us a very easy means of deployment to servers running different "flavours" of the code-base (e.g. stable, unstable, testing) by checking out a specific branch. Of course, we then use fabric to quickly do a git pull on server(s) when there's an update.

One feature of this way of working is that often find myself performing the following exact sequence of git commands:

git checkout testing
git merge stilvoid
git checkout stilvoid

to get the latest changes from my working branch into testing ready for deployment and testing in our test environment.

I don't like repeating myself.

Enter: git aliases!

I'd heard about git aliases before but I'd only seen them in the context of aliasing git ci to git commit or similar; not for creating an alias for a sequence of git commands.

Anyway, after a few minutes of playing about, I came up with the following which I hope to be of some use:

git config --local alias.merge-to '! BRANCH=$(git branch | grep "*" | cut -d " " -f 2) &amp;&amp; git checkout $1 &amp;&amp; git merge $BRANCH &amp;&amp; git checkout $BRANCH &amp;&amp; echo Merged to'</pre>

So that I can now run git merge-to testing to achieve the same as the sequence I mentioned earlier :)
