Gems to jar

Downloads ruby-complete from Maven and builds gems specified in gems.properties into their own jar.

Steps to run:

  Put name of gems in gems.properties
  Run gradle -q gemJar

The jar with the gems can now be found in dist/sassJar.jar (The name can be updated in build.gradle)

To have programmatic access to those jars, can then do:

  cd dist/
  java -jar jruby* -r./sassJar.jar -S irb

This will open the ruby shell. You should then be able to require the necessary gems.

At some point, will include a launcher, so, jruby + gems can be bundled together and run.

To run sass from inside of the ruby shell, the following works. The example is technically calling compass.

  require 'sass'
  require 'sass/exec'
  Sass::Exec::Sass.new(%W(--compass scss/common.scss:cssDir/common.css)).parse

Sample code (pulled from other code base. Will have to implement as makes sense) can be found in the sample directory.

Possible future improvements:

• Include gradle wrapper so this will just work
• Choose which version of JRuby to download.
• Make gems.properties respect versions.
• Add support for making a runnable jar that will run the gem requested.
