I modified the an example T.g from the Definitive guide section 9.4 and now
it produces no output. I only modified the grammar to take multiple
statements. I did not change the supporting code or input. Original
grammar from the book works fine and is:
grammar T;
options {output=template;}
s : ID '=' INT ';' -> assign(x={$ID.text},y={$INT.text}) ;
ID: 'a'..'z'+ ;
INT:'0'..'9'+ ;
WS :(' '|'\t'|'\n'|'\r') {skip();} ;
My modified grammar is:
grammar T;
options {output=template;}
s : (stat) + ;
stat : ID '=' INT ';' -> assign(x={$ID.text},y={$INT.text}) ;
ID: 'a'..'z'+ ;
INT:'0'..'9'+ ;
WS :(' '|'\t'|'\n'|'\r') {skip();} ;
Sample input from the book:
x=101;
What do I need to do to get the same output while supporting multiple
statements? Why does this produce no output?
