Redglob is a simple glob-style pattern matcher library for Go, inspired by Redis's pattern matching implementation. It provides a fast and easy-to-use solution for matching strings and byte slices against patterns with wildcard support.

Features

  • Unicode support
  • Case-insensitive matching
  • Capability to match strings and byte slices
  • Supports *, ?, character classes [abc], ranges [a-z], and negation [^abc]

Installing

go get github.com/maolonglong/redglob

Usage

package main

import (
	"fmt"

	"github.com/maolonglong/redglob"
)

func main() {
	pattern := "h?ll*"
	str := "hello, world!"

	if redglob.Match(str, pattern) {
		fmt.Println("Match!")
	} else {
		fmt.Println("No match.")
	}
}

Functions

  • Match(str, pattern string) bool: returns true if the given string matches the pattern.
  • MatchFold(str, pattern string) bool: case-insensitive version of Match.
  • MatchBytes(b []byte, pattern string) bool: similar to Match, but accepts a byte slice instead of a string.
  • MatchBytesFold(b []byte, pattern string) bool: case-insensitive version of MatchBytes.

Syntax

Redglob's pattern syntax is similar to that of Redis's KEYS command:

  • * matches any sequence of non-Separator characters
  • ? matches any single non-Separator character
  • c matches character c (where c is any character except *, ?, and \)
  • \c matches character c
  • [abc] matches a or b or c
  • [^abc] matches any character except a, b, or c
  • [a-z] matches a to z
  • [^a-z] matches any character except a to z

Performance

Redglob is implemented in pure Go and is optimized for performance. It uses a simple and efficient algorithm to match patterns against strings, and takes advantage of Go's built-in Unicode support to handle Unicode characters correctly.
