[antlr-interest] Recursive not supposed behaivor when finding EOF

[Marwan Ajraoui]

Hi there;

I'm getting a strange error form a parser. I have defined a grammar,
wich contains these rules;


decl_codigo :  decl_libreria decl_program

decl_libreria : TAG_START_OPEN 'function_library' ':' FN_ID TAG_CLOSE
decl_funciones TAG_END_OPEN 'function_library' TAG_CLOSE;

decl_program : TAG_START_OPEN 'program' type_return '::' FN_ID ':'
params_list TAG_CLOSE lista_instrucciones TAG_END_OPEN 'program'
TAG_CLOSE ;



 So when i finish parsing the input tested, ANTLR notifies,

line 0:-1 mismatched input '<EOF>' expecting TAG_START_OPEN

To find out what could be the problem, i put the TAG_START_OPEN , so i got:

line 0:-1 mismatched input '<EOF>' expecting  'function_library'


I did check my .g, if i have some other reference to "decl_libreria",
but No, the only reference is written is the one i mentioned before in
the lines above. it is supposed to finish without errors and return an
AST, as i set up the option.

So why it does behave in recursive way? Any idea.


thanks in advance
