Overview

A Matcher is a type of pipeline that restricts its filters to a particular pattern.

A Matcher’s pattern is a File glob.

For instance, to restrict filters to operating on JavaScript files in the app directory, the Matcher’s inputs should include “app”, and its glob would be “*.js”.

In general, you should not use Matcher directly. Instead use DSL#match in the block passed to build.

Instance Method Details

#finalize ⇒ void

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

This method returns an undefined value.

Override Rake::Pipeline#finalize to do nothing. We want to pass on our unmatched inputs to the next part of the pipeline.

def finalize
end

#output_files ⇒ Array<FileWrapper>

A list of the output files that invoking this pipeline will generate. This will include the outputs of files matching the glob and any inputs that did not match the glob.

This will make those inputs available to any additional filters or matchers.
