pugneum-parser v0.3.1

pugneum-parser

The pugneum parser transforms an array of tokens into an abstract syntax tree.

Installation

npm install pugneum-parser

Usage

var parse = require('pugneum-parser');

parse(tokens, options)

Convert pugneum tokens into an abstract syntax tree (AST).

options can contain the following properties:

• filename (string): pugneum file name; included in AST nodes and used in error handling
• plugins (array): array of plugins in the order they should be applied
• source (string): pugneum source code before tokenization; used in error handling

const lex = require('pugneum-lexer');

let filename = 'my-file.pg';
let source = 'div(data-foo="bar")';
let tokens = lex(source, {filename});

let ast = parse(tokens, {filename, source});

console.log(JSON.stringify(ast, null, '  '))
