System.require uses the following loaders:

package loader (only if module is part of a package)

load package module relative to ./lib/* (first-party) or ./vendor/**/lib/* (third-party)

System.require('package/file')

filesystem loader (available in a package or not)

Getting started with Rip

1. Clone the repo: $ git clone git://github.com/rip-lang/rip.git
2. Change into directory: $ cd rip
3. Install dependencies (requires Ruby 2): $ bundle install

Rip comes with a command-line binary at ./bin/rip. Type ./bin/rip help to see how to use Rip. Specifically the current goal is to validate the generated syntax tree by trying to break the debug output. You can run .bin/rip debug -t syntax [file] to produce a human-readable (though large) representation of the syntax tree. If you get an error, please open an issue with the exact Rip source code and a copy of the error message.

You can find out more about Rip at Rip's website (work-in-progress) and view some (hopefully still valid) examples on GitHub to get going. Please note that some examples may be outdated; pull-requests are welcome :). Also let me know if you have any trouble or are unsure about some
