David Majda 065f4e1b75 Improve location info in syntax errors
Replace |line|, |column|, and |offset| properties of |SyntaxError| with
the |location| property. It contains an object similar to the one
returned by the |location| function available in action code:

  {
    start: { offset: 23, line: 5, column: 6 },
    end:   { offset: 25, line: 5, column: 8 }
  }

For syntax errors produced in the middle of the input, |start| refers to
the first unparsed character and |end| refers to the character behind it
(meaning the span is 1 character). This corresponds to the portion of
the input in the |found| property.

For syntax errors produced the end of the input, both |start| and |end|
refer to a character past the end of the input (meaning the span is 0
characters).

For syntax errors produced by calling |expected| or |error| functions in
action code the location info is the same as the |location| function
would return.

PEG.js Spec Suite

This is the PEG.js spec suite. It ensures PEG.js works correctly. All specs should always pass on all supported platforms.

Running in Node.js

All commands in the following steps need to be executed in PEG.js root directory (one level up from this one).

  1. Install all PEG.js dependencies, including development ones:

    $ npm install

  2. Execute the spec suite:

    $ make spec

  3. Watch the specs pass (or fail).

Running in the Browser

All commands in the following steps need to be executed in PEG.js root directory (one level up from this one).

  1. Make sure you have Node.js and Python installed.

  2. Install all PEG.js dependencies, including development ones:

    $ npm install

  3. Build browser version of PEG.js:

    $ make browser

  4. Serve PEG.js root directory using a web server:

    $ python -m SimpleHTTPServer

  5. Point your browser to the spec suite.

  6. Watch the specs pass (or fail).
