GemOpen¶ ↑

Open gems into your favorite editor by running a specific gem command.

To install it just run

sudo gem install gem-open

Then add the following lines to your ~/.bash_profile file.

export GEM_EDITOR="mate"

It will default to ENV["EDITOR"], though.

Finally, run gem open GEMNAME to open that gem.

To open the most recent version you just need to type the gem name.

$ gem open activesupport

If you want to open a specific version you’ll have to type the full name.

$ gem open activesupport-3.0.0.beta3

Want some completion? Add this snippet to your ~/.bash_profile file.

_gemopencomplete() {
    local cmd=${COMP_WORDS[0]}
    local subcmd=${COMP_WORDS[1]}
    local cur=${COMP_WORDS[COMP_CWORD]}

    case "$subcmd" in
        open)
            words=`ruby -rubygems -e 'puts Dir["{#{Gem::Specification.dirs.join(",")}}/*.gemspec"].collect {|s| File.basename(s).gsub(/\.gemspec$/, "")}'`
            ;;
        *)
            return
            ;;
    esac

    COMPREPLY=($(compgen -W "$words" -- $cur))
    return 0
}

complete -o default -F _gemopencomplete gem
