Vendor Gems Quickly

Tue, 06 Apr 2010 11:43:42 -0400

Here’s a bash function to vendor gems in your Rails app.

Usage:

vg <gem name> [gem version]

This will install the gem in your ./vendor/gems directory, without installing documentation or dependencies. The version can be specific (i.e. 2.4.3) or minimal (i.e. “>= 2.4”).

Add the following to your ~/.profile:

function vg {
  if [ -z "$1" ]; then
    echo "Usage: vg  [gem version]"
  fi
  opts="--install-dir=vendor/gems --no-rdoc --no-ri --ignore-dependencies"
  if [ -n "$2" ]; then
    opts="--version $2 $opts"
  fi
  gem install $1 $opts
}

Remove merged branches in git

Fri, 02 Apr 2010 15:15:00 -0400

Here’s a bash function to help you keep your git repository clean.

It removes all branches, local and remote, that have been merged into your current branch. Simply run “rmb” from the command line. Don’t worry - prompt safeguards are in place to show you what you’ll be removing before you commit to deleting anything. And it won’t let you delete “master.” :-)

Add this to your ~/.profile, run “source ~/.profile” and you’re good to go.

function rmb {
  current_branch=$(git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/')
  if [ "$current_branch" != "master" ]; then
    echo "WARNING: You are on branch $current_branch, NOT master."
  fi
    echo "Fetching merged branches..."
  git remote prune origin
  remote_branches=$(git branch -r --merged | grep -v '/master$' | grep -v "/$current_branch$")
  local_branches=$(git branch --merged | grep -v 'master$' | grep -v "$current_branch$")
  if [ -z "$remote_branches" ] && [ -z "$local_branches" ]; then
    echo "No existing branches have been merged into $current_branch."
  else
    echo "This will remove the following branches:"
    if [ -n "$remote_branches" ]; then
      echo "$remote_branches"
    fi
    if [ -n "$local_branches" ]; then
      echo "$local_branches"
    fi
    read -p "Continue? (y/n): " -n 1 choice
    echo
    if [ "$choice" == "y" ] || [ "$choice" == "Y" ]; then
      # Remove remote branches
      git push origin `git branch -r --merged | grep -v '/master$' | grep -v "/$current_branch$" | sed 's/origin\//:/g' | tr -d '\n'`
      # Remove local branches
      git branch -d `git branch --merged | grep -v 'master$' | grep -v "$current_branch$" | sed 's/origin\///g' | tr -d '\n'`
    else
      echo "No branches removed."
    fi
  fi
}
