Defined in:
lib/rake-pipeline/reject_matcher.rb

Overview

A RejectMatcher is a pipeline that does no processing. It simply filters out some files. You can use this when you have more complex logic that doesn’t fit nicely in a glob.

You can pass a block or a glob (just like DSL#match). Files matching the glob will be rejected from the pipeline. Files are rejected when the block evaluates to true. Specify either a glob or a block.

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