agnoster-two-lines.zsh-theme

A ZSH theme optimized for people who use:

• Solarized
• Git
• Unicode-compatible fonts and terminals (I use iTerm2 + Menlo)

For Mac users, I highly recommend iTerm 2 + Solarized Dark

You can apply the patch as a 3-way merge:

git diff 13.1_dev sale_edit > patch.diff
git apply -3 patch.diff
It should bring up the conflict so that you can resolve manually. Or you could go with a one-liner, piping the patch to git-apply directly:

git diff 13.1_dev sale_edit | git apply -3
To reverse the patch:

git diff 13.1_dev sale_edit | git apply -3 -R
