Hi,
I am fairly new to ANTLR and I have come accross a problem.
I have written a simple grammar to parse huge data files (several gigabytes
each)
and antlr seems to crash by running out of memory (I am using "C" as the
target language).
The data files have the general format:
HEADER
DECL
BODY

Andreas, Jim,
Yes, this seems the right way to do it, since the actual "body data" are
pretty trivial!
I'll try working this the way you suggested!
Again, thanks for your replies!

Hi Bob,
I am in no case an antlr or grammar expert, but it appears to me that what
you want is context sensitive parsing.
http://www.antlr.org/doc/glossary.html#Context-sensitive has some notes on
how to achieve this!
Hope this helps,
Nikos

Hi Chris,
I must admit that I am fairly new to antlr, as well. Nevertheless, if I got
this correctly,
the two possible alternatives are the ones that you mentioned (which are in
some sense
equivalent)
1. "Turn off" the parser while being outside the actual language blocks and
turn it on
again when
Hi Michael,
To my understanding, the reason you get this error is that a warning
(unreferenced variable in function body - C4100) is treated as an error
because of the "Treat Errors as Warnings" switch. You can disable this from
the Project properties -> "General C/C++ options" (at least that's wh
Hi Sean,
I am not sure about this, but I think you have to rearrange the order of the
rules. More specifically,
antlr will use rules in the order they appear, therefore, WS should probably
near the end of your list.
Maybe something like this would work:
grammar Phrase;
line : WS? PHRASE EOL?;

Hi Dmitiry,
I am not sure if this is what you are looking for, but you might want to
have a look
on how the python grammar handles identation.
See for example:

ome extra cases for tabs and so
on. Personally, I would probably go for Stephen's solution (i.e. writing a
simple preprocessor), as I think
it provides a more "safe" approach.

Hi Thomas,
I am not sure if this is what you are looking for, but there is a C
preprocessor in the example
grammars (http://www.antlr.org/grammar/115121622/Cpp.tar). I think the
parts you are looking
for are in the macroDefine, macroExecution (CppTree.g) and in the
getExpansion method in

Hi Bryan,
I am assuming that you are reffering to the Java HashMap.
A "Map" is a data structure associating two sets. Think of it as a math
function
(http://en.wikipedia.org/wiki/Map_(mathematics)) where you map an element
from a set A to a set B (such that
each x\in A has only one image for maps
