Parsing with PetitParser2

In this blog we describe PetitParser2 — a modular and flexible high-performance top-down parsing framework.

Structure

Introduction

This introduction describes basics of PetitParser2 and how to migrate from PetitParser to PetitParser2.

There are other tutorials for PetitParser. We recommend the following:

• Writing Parser with PetitParser from Lukas Renggli.
• PetitParser chapter in the Deep into Pharo book.
• Introduction to PetitParser2 by Tudor Girba.

Development Guide

Describes full cycle of parser development. Starts from scripting in a playground and ends with a full-fledged, tested and high-performance parser. Covers topics such as tolerant parsing, abstract-syntax tree, optimizations and debugging.

Getting Started

The easiest way to start this tutorial is to use Moose. Moose is a software and data analysis platform that has everything we need already installed.

Alternatively, you can download clean Pharo 6 (or higher) image and install PetitParser2 using the following command:

Metacello new
	baseline: 'PetitParser2Gui';
	repository: 'github://kursjan/petitparser2';
   	load
