Dear *,
generating the C lexer and parser for the Sparql grammar using the options
below produces huge files:
options {
language = C;
output = AST;
ASTLabelType = pANTLR3_BASE_TREE;
}
2.4K Sparql.tokens
85M SparqlLexer.c <---
30K SparqlLexer.h
1.5M SparqlParser.c <---
69K SparqlParser.h
In addition, the files cannot be compiled as it seems that the generators have
not been updated to reflect the API changes in the latest C runtime (or maybe
it is the other way round :)). In particular, I see errors like these:
SparqlLexer.c:1214276:48: error: member reference type 'pANTLR3_STRING' (aka
'struct ANTLR3_STRING_struct *') is a
pointer; maybe you meant to use '->'?
setText(LEXER->getText(LEXER).substring(1,
LEXER->getText(LEXER).length()-1));
~~~~~~~~~~~~~~~~~~~~~^
->
SparqlLexer.c:1214276:49: error: no member named 'substring' in 'struct
ANTLR3_STRING_struct'; did you mean 'subString'?
setText(LEXER->getText(LEXER).substring(1,
LEXER->getText(LEXER).length()-1));
^~~~~~~~~
subString
./antlr3string.h:179:8: note: 'subString' declared here
(*subString) (struct
ANTLR3_STRING_struct * string, ANTLR3_UINT32 ...
^
SparqlLexer.c:1214276:83: error: member reference type 'pANTLR3_STRING' (aka
'struct ANTLR3_STRING_struct *') is a
pointer; maybe you meant to use '->'?
setText(LEXER->getText(LEXER).substring(1,
LEXER->getText(LEXER).length()-1));
~~~~~~~~~~~~~~~~~~~~~^
->
SparqlLexer.c:1214276:84: error: no member named 'length' in 'struct
ANTLR3_STRING_struct'
setText(LEXER->getText(LEXER).substring(1,
LEXER->getText(LEXER).length()-1));
I'm using antlr 3.4, but I have also tested this with antlr 3.3. Generating the
Java lexer and parser works as expected and the files are much smaller:
2.4K Sparql.tokens
582K SparqlLexer.java
876K SparqlParser.java
Any suggestions and help are highly appreciated.
Thanks in advance,
Todor
