@module file-contains.js
###

# Set up a regex that matches all of the following:
#
#   - FRESH
#   - JRS
#   - FRESCA
#   - FRESH@1.0.0
#   - FRESH@1.0
#   - FRESH@1
#   - JRS@0.16.0
#   - JRS@0.16
#   - JRS@0
#
# Don't use a SEMVER regex (eg, NPM's semver-regex) because a) we want to
# support partial semvers like "0" or "1.2" and b) we'll expand this later to
# support fully scoped FRESH versions.

module.exports = () ->
  RegExp '^(FRESH|FRESCA|JRS)(?:@(\\d+(?:\\.\\d+)?(?:\\.\\d+)?))?$'
