David Majda 8a0276ffb7 Unify checks and passes 
There is no real reason to have them separated.
 2011-10-03 14:57:09 +02:00
David Majda 6cd5bdc5e6 Passes now do not return anything (they always modify the AST in-place) 2011-10-03 14:57:09 +02:00
David Majda 3983f46d5d Rename |reportMissingReferencedRules| check to |reportMissingRules| 
The new name is shorter, there is no real loss of meaning.

David Majda afdcb6fc4f Fix |posStackDepth| computation for rules

 2011-09-30 17:57:48 +02:00
David Majda 756b6fc473 Fix |resultStackDepth| computation for sequences 
The |1 + ...| was wrong -- sequence does not need its own variable since
it reuses the one used by the first item.

Part of a fix for GH-53.

David Majda b540b2d460 Implement case-insensitive literal matching 2011-09-30 11:20:37 +02:00
David Majda 1c11e4aaa3 Split |literal| rule in the PEG.js grammar to |literal| and |string| 
This is just a formality now but it will make sense later when literals
(but not strings) will allow "i" flag for case-insensitive matching.

David Majda 0748fee1d3 Use Codie for code templates 
This will allow moving some code into the templates later.
 2011-09-24 17:09:45 +02:00
David Majda 38c25efde0 Use single quotes for code in the emitter 
Strings with code should use single quotes so that double quotes (which
I generally prefer) could be used in the code itself without escaping.
