Module: XMP2Assert::Classifier

Defined in:
lib/xmp2assert/classifier.rb

Overview

Usually, you want to check LOTS of files that may or may not contain xmp comments at once, maybe from inside of a CI process. That's OK but we want to speed things up, so here we filter out files that are not necessary to convert.

Typical usage:

Pathname.glob('**/*.rb').select do |f|
  XMP2Assert::Classifier.classify(f)
end
