Gem Info

A rubygems plugin which adds an ‘info’ command that prints information about installed gems.

Unlike the built-in gem commands, it allows fuzzy matching on gem names and versions by default, and allows precise formatting of the output, making it easy on the command line and in scripts.

Examples

View dependencies at a glance:

$ gem info -f '%name-%version: %dependencies' act
activesupport-2.3.3: 
activesupport-2.3.4: 
activeresource-2.3.4: activesupport = 2.3.4
activerecord-2.3.4: activesupport = 2.3.4
actionpack-2.3.4: activesupport = 2.3.4, rack ~> 1.0.0
actionmailer-2.3.4: actionpack = 2.3.4

Handy alias to ‘cd’ to a gem directory:

function cdrg {
    if [ $# -eq 0 ]; then
        cd `gem env gemdir`/gems
    elif gem info --exactly-one $@ > /dev/null; then
      local dir=`gem info -f '%path' $@`
      if [ -d $dir/lib ]; then
          cd $dir/lib
      else
          cd $dir
      fi
    fi
}

$ cdrg rails    # oops!
2 matching gems:
  rails 2.3.3
  rails 2.3.4
$ cdrg rails 4  # only 2.3.4 contains '4'
$ pwd
/usr/lib/ruby/gems/1.8/gems/rails-2.3.4/lib
