The previous default name was "exports.parser". This meant that to use
the generated parser in Node.js, you had to use code like this:
var parser = require("./my-cool-parser").parser;
parser.parse(...);
Now you can shorten it a bit:
var parser = require("./my-cool-parser");
parser.parse(...);
The shorter version makes sense since no other objects except the parser
are exported from the module.
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.
Before this change, the start rule was the one named "start" and there
was an option to override that. This is now impossible.
The goal of this change is to contain all information for the parser
generation in the grammar itself.
In the future, some override directive for the start rule (like Bison's
"%start") may be added to the grammar.
Similar issue exists on Windows too (they have symlinks since Vista), but I
could not find how to dereference symlinks from batch files, so I did not fix
it. I guess this does not matter much given how little the symlinks are used in
the Windows world.
Closes#1.
