# LPeg for Defold

LPeg extension for the Defold game engine. [LPeg](http://www.inf.puc-rio.br/~roberto/lpeg/) is a pattern-matching library by [Roberto Ierusalimschy](http://www.inf.puc-rio.br/~roberto/) for Lua.

The extension includes source code of LPeg 1.0.2 (MIT Licence).

## Installation

Add the link to the latest [release zip-archive](https://github.com/astrochili/defold-lpeg/releases) as a [library dependency](http://www.defold.com/manuals/libraries/) in the Defold project configuration.

## Usage

All operations are accessible through the global variable ```lpeg```.

```lua

local P = lpeg.P 

local pattern = P'a' * P'b' ^ 0

local result = lpeg.match(pattern, 'abbc')

print(result) --> 4

```

## Narrator

This library is used by [Narrator](https://github.com/astrochili/narrator) to parse the Ink language. You can check how its parser works [here](https://github.com/astrochili/narrator/blob/master/narrator/parser.lua).
