The code has been ported to Python and a lot of utility functions have been added.\n\nGrammar Features\n=================\n\n* Symbolic Values\n   * Constants\n      * such as ```true```, ```false``` and ```null```\n      * configurable: Arbitrary constants can be added\n   * Identifiers\n      * may contain  $,\\_ or alphanumeric chacraters but may not start with a number\n      * can include property names and accessors, for example `foo`, `bar.baz`, `foo['bar'].baz`\n* Various types of literals\n   * Numeric Literals (```42.001```)\n      * decimal notation (```-42```)\n      * exponential notation (```6.7E-10```)\n   * String Literals (```\"Hello world\"```)\n      * can be either double or single quotes\n      * special characters can be escaped\n   * Array Literals (```[1, 2, 3]```)\n      * must be surrounded by square brackets\n      * can be nested\n* Multiple types of operators\n   * Unary operators\n      * by default ```-```, ```!```, ```~``` and ```+```\n      * custom operators can be added, existing ones can be removed\n   * Binary operators\n      * precedence based\n      * by default contains all JavaScript operators\n      * custom ones can be added with custom precedences\n      * brackets can be used to override precedences\n   * JavaScript Conditional operator\n      * single ternary operator ```a ? b : c```\n* Call Expressions\n   * must use round brackets\n   * for example ```Math.cos(x)```\n\nAPI\n===\n\nThe API in JavaScript and python are almost identical. The only differences come from the features of the languages themselves.\n\n.. code:: javascript\n\n  var parser = new PreJsPy(); // creates a new parser\n\n  parser.getConstants() // returns an object containing constants\n  parser.setConstants(d) // sets the current constants know to the parser\n\n  parser.getUnaryOperators() // gets an array of unary operators\n  parser.setUnaryOperators(ary) // sets an array of unary operators\n\n  parser.getBinaryOperators() // returns an object mapping binary operators to their precedence\n  parser.setBinaryOperators(ary) // sets the binary operators to precedence mapping\n\n  parser.parse(s) // parses a string into a AST\n\n.. code:: python\n\n  parser = PreJsPy() # creates a new parser\n\n  parser.getConstants() # returns an object containing constants\n  parser.setConstants(d) # sets the current constants know to the parser\n\n  parser.getUnaryOperators() # gets an array of unary operators\n  parser.setUnaryOperators(ary) # sets an array of unary operators\n\n  parser.getBinaryOperators() # returns an object mapping binary operators to their precedence\n  parser.setBinaryOperators(ary) # sets the binary operators to precedence mapping\n\n  parser.parse(s) # parses a string into a AST\n\nInstall\n=======\n\nThis package is published on the\n`Python Package Index <https://pypi.python.org/pypi/pre_js_py>`_\nInstallation can be done simply via pip:\n\n.. code:: bash\n\n   pip install pre_js_py\n\nIt is also published on\n`Nodejs Package Manager <https://www.npmjs.com/package/pre-js-py>`_\nInstallation can be done simply via npm:\n\n.. code:: bash\n\n   npm install pre-js-py\n\n\nLicense + Acknowledgements\n==========================\n\nThis module and associated documentation is Copyright (c) Tom Wiesing 2016\nand licensed under the MIT license, see `license <LICENSE>`_ for details.\n\n\n",
