Following https://developers.google.com/closure/compiler/docs/api-tutorial3#howto-app and https://github.com/documentcloud/closure-compiler it should be easy to use something like:

javascript_compressor: closure
#  compilation_level: "ADVANCED_OPTIMIZATIONS"
#  externs: src/js/externs.js

Looks like the externs parameter is not recognized

Hey @chris-rock have you checked out the usage instructions on how to use the advanced optimizations in your own compilation scripts? https://github.com/documentcloud/closure-compiler#usage

Ah looks like you have. Pull requests always welcome :)

I'm not sure how could this work without custom parsing in Jammit. You can pass multiple externs parameters to Closure compiler on the CLI, but will that work in YAML?

For example:

javascript_compressor: closure
  compilation_level: "ADVANCED_OPTIMIZATIONS"
  externs: src/js/jquery.js
  externs: src/js/my_externs.js
