A simple parser combinator library heavily inspired by nom. This library is more of a personal excersise to learn the Dart programming language. It is not meant to be a full rewrite of nom, since i'm not planning on expanding it a whole lot. It is not particularly optimized for speed and cannot be used with binary data.

It is just a quick and dirty library to create string parsers.

Allows you to write parsers using simple combinators. Here are the parsers and combinators you can use.

Parsers:

• tag
• take
• takeTill *
• takeUntil *
• takeWhile *
• takeAll *

• Also has a variant that needs to have at least one character matched.

Combinators:

• opt
• alt
• list

Utilities:

• map
• del
• clear

Example on how to match markdown links:

final parser = list([
  tag("["),
  takeUntil("]"),
  tag("]("),
  takeUntil(")"),
  tag(")")
]);

var (value, tail) = parser("[test](https://www.github.com)");
var [_, text, _, url, _] = value;
