Zsh functions for making it easy to work with large godeps in production. Add to .zshrc and use in your normal workflow

godep_zsh_tools.zsh

# Just like regular godep, use at root of repo
godep() {
    case $* in
            rebuild* ) shift; command rm -rf Godeps && rm -rf vendor && godep save;;
            remove* ) shift; command rm -rf Godeps && rm -rf vendor;;
            * ) command godep "$@";;
    esac
    return
}

# Usage: create godep-rebuild branch (or use a custom branch name) from a specific commit. 
# This commit should be located at the point where you'd normally merge your new branch into dev or master.
# Make your changes on your branch for your new fix or feature, commit changes, then run depmerge.
# Submit your pr to the godep-rebuild (or custom branch name) on github.
# Github incorrectly shows more file changes thn actually exist between the two diffs, so depmerge automatically prints out a list of the changed files between the two branches on each run.
# You'll have to use git diff or a visual diff tool to view file changes instead of github's web client, if you want to view a proper diff.
# On the plus side, this method works for situations where you've commited both package files and vendored dependencies in the same commit, and separates those changes easily while preserving commit history :D
