David Majda 5b3321d302 Implement |cache| option for |PEG.buildParser| 
This option enables/disables the results cache in generated parsers.
Until now, it was always enabled, but after this commit it needs to be
enabled explicitly (i.e. the |cache| option default value is |false|).
The reason is that parsing without it is *much* faster according to the
benchmark.

Note that disabling the cache breaks the linear parsing time guarantee,
meaning that with some grammars you can get exponential parsing time
with respect to the input length. This, together with the possibility of
improving the cache performance in the future, is the reason to keep it
as an option.

David Majda 52d7ec2224 Implement |trackLineAndColumn| option for |PEG.buildParser| 
This option makes the generated parser track line and column during
parsing. Tracked line and column are made available inside actions and
predicates as |line| and |column| variables.

Note that in actions these variables denote start position of the
action's expression while in predicates they denote the current
position. The slightly different behavior is motivated by expected
usage.

David Majda 4d5b1d58aa AST: Store rules in an array instead of an object 
This simplifies the code a bit and makes the AST more regular (each node
type has a fixed set of properties). The latter may get useful later
when generalizing visitors.

 2012-02-27 20:18:21 +01:00
David Majda 4cf50bcf9f Move param computations from the emitter into a separate pass 
This has two main benefits:

  1. The knowledge about scoping params in at one designated place,
     making all future adjustments in this area easier.

  2. Action-related code does not handle sequences specially anymore.
     Such knowledge/behavior doesn't belong there.
 2012-02-27 20:18:03 +01:00
David Majda efc38eef9b Consolidate all variable name computations into one compiler pass 
Before this change, knowledge about variable names was spread between
the |computeStackDepths| pass and the code emitter code. For example,
the fact that the |&...| expression needs one variable to store a
position was represented in both places.

This changes consolidates that knowledge and introduces a new
|computeVarNames| pass. This pass replaces old |computeStackDepths|
pass, does all computations realted to variable names and stores the
results in the AST. Note that some knowledge about variables
(inevitably) remained in emitter code templates.

Beside DRYing things up, this change simplifies the emitter
significantly. By storing variable names in the AST it also allows
introduction of a pass that will identify parameters passed to actions
using proper symbol tables. Right now, this is done in a hackish way
directly in the emitter, which won't work well with changes planned in
GH-69.
