modulr is a CommonJS module implementation
in Ruby for client-side JavaScript.
$ [sudo] gem install modulr
modulr accepts a singular file as input (the program) on which is does static
analysis to recursively resolve its dependencies.
The program, its dependencies and a small, namespaced JavaScript library are concatenated into a single js file. This
improves load times by minimizing HTTP requests.
The bundled JavaScript library provides each module with the necessary require
function and exports and module free variables.
modulr is available as a Ruby program or as a command-line utility (modulrize).
To run the specs, first clone the Git repository then grab the CommonJS specs, included as a Git submodule, by running:
$ git clone git://github.com/codespeaks/modulr.git
$ cd modulr
$ git submodule init
$ git submodule update
Mozilla's SpiderMonkey is required
and the js command line executable must be available on the load path (try which js).
You can run all the specs by issuing:
$ rake spec
Alternatively, a list of comma-separated specs can be specified through the SPECS
environment variable (see vendor/commonjs/tests/modules/1.0) for a comprehensive
list of available specs).
$ rake spec SPECS=absolute,transitive
