A library for building RegExpPatterns. It is not available as a nuget package yet, because I would like to add some more features to it, before relasing a package. I'm not great at writing regex, so I would really appreciate any feedback if you have any.
A linq extensions style of building RegExpPatterns in .NET.

Good code is simple code.
Which one of these snippets of code do you want to find in your code?
var regEx = {(?:^)[A-Za-z]([A-Za-z]+|(?:\d+))(@{1,1})[A-Za-z]+(.{1,1})[A-Za-z]+(?:$)}
or
var builder = new Builder.RegExpBuilder();
var r = builder
.StartOfInput()
.Letter() // Must start with letter a-z
.Letters() // any number of letters
.Or()
.Digits() // any number of numbers
.Exactly(1).Of("@")
.Letters() // domain
.Exactly(1).Of(".")
.Letters() // top-level domain
.EndOfInput()
.ToRegExp();
#How to use it
var builder = new Builder.RegExpBuilder();
var r = builder
.StartOfLine()
.Exactly(1).Of("github")
.Or()
.Exactly(1).Of("bitbucket")
.EndOfLine()
.ToRegExp();
// r.ToString() == "(?:^)(github{1,1}|(?:bitbucket{1,1}))(?:$)"
Assert.IsTrue(r.Match("github").Success, "Found one Github");
Assert.IsTrue(r.Match("bitbucket").Success, "Found one Bitbucket");
Assert.IsFalse(r.Match("githubgithub").Success, "Oops, Found too Many Github");
Assert.IsFalse(r.Match("bitbucketbitbucket").Success, ""Oops, Found too Many Github");
var builder = new Builder.RegExpBuilder();
var r = builder
.StartOfLine()
.Digit()
.EndOfLine()
.ToRegExp();
r.Match("1").Success; // true
r.Match("11").Success); // false
public void ExactlyOfCustom()
{
var builder = new Builder.RegExpBuilder();
var r = builder
.StartOfLine()
.Exactly(3)
.Of("a")
.EndOfLine()
.ToRegExp();
Assert.IsTrue(r.Match("aaa").Success, "Three Letters");
Assert.IsFalse(r.Match("aaaa").Success, "four Letters");
Assert.IsFalse(r.Match("aa").Success, "two Letters");
}
