wildcard

Documentation

Overview

Package wildcard implements a very simple wildcard matcher which supports only the term '*', which matches any sequence of characters. The match function, WildcardMatch, both parses the pattern and matches the target; there is no compile stage and WildcardMatch can be a drop in replacement anywhere a normal string comparison is done.

This package is very similar to and inspired by github.com/ryanuber/go- glob, but with performance optimizations; github.com/gobwas/glob offers a much richer glob syntax and faster performance for cases where a compiled glob state can be maintained.
