php-unparser

Build Status Coverage Status

This project is a JavaScript based unparser for the AST produced by glayzzle's php-parser.

It aims to produce code that uses the style format recommended by PSR-1 and PSR-2.

It's at an early development stage, but it is already able to generate code for most of the produced AST.

It has no dependencies.

How to use

var unparse = require('php-unparser');

var options = {
  indent: true,
  dontUseWhitespaces: false,
  shortArray: true,
  bracketsNewLine: true,
  forceNamespaceBrackets: false,
  collapseEmptyLines: true
};

var ast = {
  "kind": "program",
  "children": [
    {
      "kind": "echo",
      "arguments": [
        {
          "kind": "string",
          "value": "hello world",
          "isDoubleQuote": true
        }
      ]
    }
  ],
  "errors": []
};

// Will output -> echo "hello world";
console.log(unparse(ast, options));
