David Majda 58806a3d77 Label scope specs: Add negative specs (subexpressions) 
Semantic predicate and action specs which verified label scope didn't
exercise labels in subexpressions. This commit adds cases exercising
them, including few commented-out cases which reveal #396 (these will be
uncommented when the bug gets fixed).

Note that added specs exercise all relevant expression types. This is
needed because code that makes subexpression labels invisible to the
outside is separate for each expression type so one generic test
wouldn't generate enough coverage.

Part of a fix of #396.

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).
