HRE: Haxe Regular Expressions

Pure Haxe Regular Expression Engine based on ES7-core.

This is a pure Haxe implementation that guarantees full reproducibility of the results across all the targets (as opposed to the EReg class from the standard library). You should note that to ensure reproducibility across all targets you may get slower results.

Currently, this library passes all the official ES7 RegExp tests (see Test262), except for one test that involves a very complex RegExp and fails due to performance issues (timeout).

The next goal would be to introduce some differences with the ES7 spec to use Unicode as the primary text representation and support Unicode grapheme clusters. Now that the baseline is implemented, work on the performance of the engine is also planned.

Requires Haxe 3.1.

Installation

Install it from haxelib:

haxelib install hre 0.2.1

Usage

Help wanted: improve the documentation

new hre.RegExp(patternSource, flags)

Create a new RegExp

regExp.exec(inputString)

Execute the regular expression on the provided input string and return the result with the matched slice and capture groups.

regExp.test(inputString)

Returns a boolean indicating if the inputString is matched by the regExp.
