Top 5 Golang Libraries for Regular Expressions

In today's post we will learn about Top 5 Golang Libraries for Regular Expressions.

What is a Regular Expression?

Regular expressions are specially encoded text strings used as patterns for matching sets of strings. They began to emerge in the 1940s as a way to describe regular languages, but they really began to show up in the programming world during the 1970s. The first place I could find them showing up was in the QED text editor written by Ken Thompson.

“A regular expression is a pattern which specifies a set of strings of characters; it is said to match certain strings.” —Ken Thompson

Regular expressions later became an important part of the tool suite that emerged from the Unix operating system—the ed, sed and vi (vim) editors, grep, AWK, among others. But the ways in which regular expressions were implemented were not always so regular.

Table of contents:

  • Genex - Count and expand Regular Expressions into all matching Strings.
  • Go-wildcard - Simple and lightweight wildcard pattern matching.
  • Goregen - Library for generating random strings from regular expressions.
  • Regroup - Match regex expression named groups into go struct using struct tags and automatic parsing.
  • Rex - Regular expressions builder.

1 - Genex:

Count and expand Regular Expressions into all matching Strings.

Easy and efficient package to expand any given regex into all the possible strings that it can match.

This is the code that powers namegrep.

Usage

package main

import (
    "fmt"
    "regexp/syntax"

    "github.com/alixaxel/genex"
)

func main() {
    charset, _ := syntax.Parse(`[0-9a-z]`, syntax.Perl)

    if input, err := syntax.Parse(`(foo|bar|baz){1,2}\d`, syntax.Perl); err == nil {
    	fmt.Println("Count:", genex.Count(input, charset, 3))

    	genex.Generate(input, charset, 3, func(output string) {
    		fmt.Println("[*]", output)
    	})
    }
}

Output

Count: 120

[*] foo0
[*] ...
[*] foo9
[*] foofoo0
[*] ...
[*] foofoo9
[*] foobar0
[*] ...
[*] foobar9
[*] foobaz0
[*] ...
[*] foobaz9
[*] bar0
[*] ...
[*] bar9
[*] barfoo0
[*] ...
[*] barfoo9
[*] barbar0
[*] ...
[*] barbar9
[*] barbaz0
[*] ...
[*] barbaz9
[*] baz0
[*] ...
[*] baz9
[*] bazfoo0
[*] ...
[*] bazfoo9
[*] bazbar0
[*] ...
[*] bazbar9
[*] bazbaz0
[*] ...
[*] bazbaz9

2 - Go-wildcard:

Simple and lightweight wildcard pattern matching.

Why

This part of Minio project, a very cool, fast and light wildcard pattern matching.

Originally the purpose of this fork is to give access to this "lib" under Apache license, without importing the entire Minio project ...

Two function are available MatchSimple and Match

  • MatchSimple only covert * usage (which is faster than Match)
  • Match support full wildcard matching, * and ?

I know Regex, but they are much more complex, and slower (even prepared regex) ...
I know Glob, but most of the time, I only need simple wildcard matching.

How to

⚠️ WARNING: Unlike the GNU "libc", this library have no equivalent to "FNM_FILE_NAME". To do this you can use "path/filepath" https://pkg.go.dev/path/filepath#Glob

Using this fork

go get github.com/IGLOU-EU/go-wildcard@latest

Using Official Minio (GNU Affero General Public License 3.0 or later)

From https://github.com/minio/minio/commit/81d5688d5684bd4d93e7bb691af8cf555a20c28c the minio pkg are moved to https://github.com/minio/pkg

go get github.com/minio/pkg/wildcard@latest

Quick Example

This example shows a Go file with pattern matching ...

package main

import (
	"fmt"

	wildcard "github.com/IGLOU-EU/go-wildcard"
)

func main() {
    str := "daaadabadmanda"
    
    pattern := "da*da*da*"
    result := wildcard.MatchSimple(pattern, str)
	fmt.Println(str, pattern, result)

    pattern = "?a*da*d?*"
    result = wildcard.Match(pattern, str)
	fmt.Println(str, pattern, result)
}

3 - Goregen:

Library for generating random strings from regular expressions.

Package regen is a library for generating random strings from regular expressions. The generated strings will match the expressions they were generated from. Similar to Ruby's randexp library.

E.g.

regen.Generate("[a-z0-9]{1,64}")

will return a lowercase alphanumeric string between 1 and 64 characters long.

Expressions are parsed using the Go standard library's parser: http://golang.org/pkg/regexp/syntax/.

Constraints

"." will generate any character, not necessarily a printable one.

"x{0,}", "x*", and "x+" will generate a random number of x's up to an arbitrary limit. If you care about the maximum number, specify it explicitly in the expression, e.g. "x{0,256}".

Flags

Flags can be passed to the parser by setting them in the GeneratorArgs struct. Newline flags are respected, and newlines won't be generated unless the appropriate flags for matching them are set.

E.g. Generate(".|[^a]") will never generate newlines. To generate newlines, create a generator and pass the flag syntax.MatchNL.

The Perl character class flag is supported, and required if the pattern contains them.

Unicode groups are not supported at this time. Support may be added in the future.

Concurrent Use

A generator can safely be used from multiple goroutines without locking.

A large bottleneck with running generators concurrently is actually the entropy source. Sources returned from rand.NewSource() are slow to seed, and not safe for concurrent use. Instead, the source passed in GeneratorArgs is used to seed an XorShift64 source (algorithm from the paper at http://vigna.di.unimi.it/ftp/papers/xorshift.pdf). This source only uses a single variable internally, and is much faster to seed than the default source. One source is created per call to NewGenerator. If no source is passed in, the default source is used to seed.

The source is not locked and does not use atomic operations, so there is a chance that multiple goroutines using the same source may get the same output. While obviously not cryptographically secure, I think the simplicity and performance benefit outweighs the risk of collisions. If you really care about preventing this, the solution is simple: don't call a single Generator from multiple goroutines.

Benchmarks

Benchmarks are included for creating and running generators for limited-length, complex regexes, and simple, highly-repetitive regexes.

go test -bench .

The complex benchmarks generate fake HTTP messages with the following regex:

POST (/[-a-zA-Z0-9_.]{3,12}){3,6}
Content-Length: [0-9]{2,3}
X-Auth-Token: [a-zA-Z0-9+/]{64}

([A-Za-z0-9+/]{64}
){3,15}[A-Za-z0-9+/]{60}([A-Za-z0-9+/]{2}==|[A-Za-z0-9+/]{3}=)

The repetitive benchmarks use the regex

a{999}

See regen_benchmarks_test.go for more information.

On my mid-2014 MacBook Pro (2.6GHz Intel Core i5, 8GB 1600MHz DDR3), the results of running the benchmarks with minimal load are:

BenchmarkComplexCreation-4                       200	   8322160 ns/op
BenchmarkComplexGeneration-4                   10000	    153625 ns/op
BenchmarkLargeRepeatCreateSerial-4  	        3000	    411772 ns/op
BenchmarkLargeRepeatGenerateSerial-4	        5000	    291416 ns/op

4 - Regroup:

Match regex expression named groups into go struct using struct tags and automatic parsing.

Simple library to match regex expression named groups into go struct using struct tags and automatic parsing

Installing

go get github.com/oriser/regroup

Example

Named groups map

package main

import (
	"fmt"
	"github.com/oriser/regroup"
)

var re = regroup.MustCompile(`(?P<duration>.*?)\s+(?P<num>\d+)\s+(?P<foo>.*)`)

func main() {
	matches, err := re.Groups("5s 123 bar")
	if err != nil {
		panic(err)
	}
	fmt.Printf("%+v\n", matches)
}

Will output: map[duration:5s foo:bar num:123]

Single match

package main

import (
	"fmt"
	"github.com/oriser/regroup"
	"time"
)

var re = regroup.MustCompile(`(?P<duration>.*?)\s+(?P<num>\d+)\s+(?P<foo>.*)`)

type B struct {
	Str string `regroup:"foo"`
}

type A struct {
	Number        int           `regroup:"num"`
	Dur           time.Duration `regroup:"duration"`
	AnotherStruct B
}

func main() {
	a := &A{}
	if err := re.MatchToTarget("5s 123 bar", a); err != nil {
		panic(err)
	}
	fmt.Printf("%+v\n", a)
}

Will output: &{Number:123 Dur:5s AnotherStruct:{Str:bar}}

5 - Rex:

Regular expressions builder.

Why?

It makes readability better and helps to construct regular expressions using human-friendly constructions. Also, it allows commenting and reusing blocks, which improves the quality of code. It provides a convenient way to use parameterized patterns. It is easy to implement custom patterns or use a combination of others.

It is just a builder, so it returns standart *regexp.Regexp.

The library supports groups, composits, classes, flags, repetitions and if you want you can even use raw regular expressions in any place. Also it contains a set of predefined helpers with patterns for number ranges, phones, emails, etc...

Let's see an example of validating or matching someid[#] using a verbose pattern:

re := rex.New(
    rex.Chars.Begin(), // `^`
    // ID should begin with lowercased character.
    rex.Chars.Lower().Repeat().OneOrMore(), // `[a-z]+`
    // ID should contain number inside brackets [#].
    rex.Group.NonCaptured( // (?:)
        rex.Chars.Single('['),                   // `[`
        rex.Chars.Digits().Repeat().OneOrMore(), // `[0-9]+`
        rex.Chars.Single(']'),                   // `]`
    ),
    rex.Chars.End(), // `$`
).MustCompile()

Yes, it requires more code, but it has its advantages.

More, but simpler code, fewer bugs.

You can still use original regular expressions as is in any place. Example of matching numbers between -111.99 and 1111.99 using a combination of patterns and raw regular expression:

re := rex.New(
    rex.Common.Raw(`^`),
    rex.Helper.NumberRange(-111, 1111),
    rex.Common.RawVerbose(`
        # RawVerbose is a synonym to Raw,
        # but ignores comments, spaces and new lines.
        \.        # Decimal delimter.  
        [0-9]{2}  # Only two digits.
        $         # The end.
    `),
).MustCompile()

// Produces:
// ^((?:\x2D(?:0|(?:[1-9])|(?:[1-9][0-9])|(?:10[0-9])|(?:11[0-1])))|(?:0|(?:[1-9])|(?:[1-9][0-9])|(?:[1-9][0-9][0-9])|(?:10[0-9][0-9])|(?:110[0-9])|(?:111[0-1])))\.[0-9]{2}$

).MustCompile()

Yes, it requires more code, but it has its advantages.

More, but simpler code, fewer bugs.

You can still use original regular expressions as is in any place. Example of matching numbers between -111.99 and 1111.99 using a combination of patterns and raw regular expression:

re := rex.New(
    rex.Common.Raw(`^`),
    rex.Helper.NumberRange(-111, 1111),
    rex.Common.RawVerbose(`
        # RawVerbose is a synonym to Raw,
        # but ignores comments, spaces and new lines.
        \.        # Decimal delimter.  
        [0-9]{2}  # Only two digits.
        $         # The end.
    `),
).MustCompile()

// Produces:
// ^((?:\x2D(?:0|(?:[1-9])|(?:[1-9][0-9])|(?:10[0-9])|(?:11[0-1])))|(?:0|(?:[1-9])|(?:[1-9][0-9])|(?:[1-9][0-9][0-9])|(?:10[0-9][0-9])|(?:110[0-9])|(?:111[0-1])))\.[0-9]{2}$

When I was a wee lad, we used to play at Mad Libs for hours and hours. This was before computers, mind you, before televisions or radio or even paper! No, scratch that, we had paper. Anyway, the point is we only had Mad Libs to play, and we loved it! And now you must play!

We’ll write a program called mad.py  which reads a file given as a positional argument and finds all the placeholders noted in angle brackets like <verb>  or <adjective> . For each placeholder, we’ll prompt the user for the part of speech being requested like “Give me a verb” and “Give me an adjective.” (Notice that you’ll need to use the correct article.) Each value from the user replaces the placeholder in the text, and if the user says “drive” for “verb,” then <verb>  in the text replaces with drive . When all the placeholders have been replaced with inputs from the user, print out the new text.
