Adding Ruby to Run Shell Script

Published by Sean Long on September 17, 2005 under Blog Posts

If you want to interact with Ruby from within Automator you can do the following:

Add this XML:

<key>/usr/bin/ruby</key>
<dict>
    <key>args</key>
    <array>
        <string>-e</string>
        <string>%</string>
        <string>--</string>
    </array>
    <key>script</key>
    <array>
        <string>$stdin.each { |arg| puts arg }</string>
        <string>ARGV.each { |arg| puts arg }</string>
    </array>
</dict>

to the file:

/System/Library/Automator/Run Shell Script.action/Contents/Resources/Shells.plist

Now when Automator is restarted /usr/bin/ruby will show up in the Shells: list of action Run Shell Script.

I got the idea from this Apple Discussion post telling how to add PHP.
