Inherits:
NodeConstraint show all
Defined in:
lib/yes/constraints/fnmatch.rb

Overview

Validate file glob match. This uess standard unix-style file matching, primarily ‘*` and `?`, to detrmine a mathing node value. All values are converted to strings (using #to_s) for comparison. – TODO: better name then `FNMatch`? ++
