David Majda afcceb127f Add command-line runner for the test suite

David Majda 4c59bbfef9 Fixes to previous commit
Require PEG only in the "parser" task -- it may not exist when executing
the "build" task. Also don't make the "build" task dependent on the
"parser" to break a dependency circle.

David Majda f3845726f2 Rakefile -> Jakefile
Or, swapped Ruby dependency for a Node dependency.

The build script was also modified to always regenerate the parser (in
case of the "parser" task) or rebuild the library (in case of the
"build" task) even if the source files were not modified. Not doing this
led to problems when the generating code changed but the files didn't
(which happened often during development).

David Majda aeb2cb4f1c Make sure quoting functions output only ASCII characters
This patch prevents portability problems. In particular, it fixes a
problem where "SyntaxError: Invalid range in character class." error
appeared when using command-line version on Widnows (see GH-13).

David Majda 2d38c5cab3 Handle non-unique expected values of match failuers differently
Before this commit, uniqueness was checked when addding the failure. Now
we make the entiries unique when generating the error report, saving a
little time when the parsing is successful. This does not increase the
benchmark numbers too much though.

David Majda c8836c0312 Remove two unused variables 14 years ago
David Majda 7b03f164b8 Avoid passing |context| in the generated parser
Passing the context is not necessary, global variable is good enough
(passing the context would make more sense if each AST node was
translated into a function call, but this isn't the case).

The performance gain is very small, on the border of statstical error.

David Majda 5ab36f8018 Split the vendor directory
There are now three vendor directories. The goal is to have test- and
benchmark-specific stuff is its own directories and not in the main one.

David Majda 9e2fc76fc5 Rakefile: Rename "metaparser" task to "parser"
This is more consistent with nomenclature in the code and with the file
names.
14 years ago
David Majda e59f3ba338 Split the source code into several files, introduce build system
The source code is now in the src directory. The library needs to be
built using "rake", which creates the lib/peg.js file by combining the
source files.

David Majda 95a78892de Rename |PEG.compiler.compileParser| to |PEG.compiler.compile|
It's shorter and more consistent with |PEG.parser.parse|.
14 years ago
David Majda 5e64d09a15 Renamed some properties of the |PEG| object
1. |PEG.Compiler| -> |PEG.compiler|
2. |PEG.grammarParser| -> |PEG.parser|

This brings us closer to the desired structure of the PEG object, which
is:

  +-PEG
    |- parser
    +- compiler
       |- checks
       |- passes
       +- emitter

These are the only things (together with the |PEG.buildParser| function
and exceptions) that I want to be publicly accessible -- as extension
points and also for easy testing of PEG.js's components.
