Hello,
I would like to add file+line+column information to code generatedfrom an
AST tree.
IE:
// in lexer
statement:
: 'for' '(' start=expression? ';' cond=expression? ';'
next=expression? ')' body=statement
-> ^('for' $cond $next $body $start )
...
;
// in tree
statement
: ^('for' cond=continuation step=continuation body=continuation
expression) { AppendOp(Operation::ForLoop); }
...
;
My question is, how can I access file, line and column information for
tokens used by the tree parser? in the example above, how can I access the
location of the 'for' token used in the tree grammar to pass to the
AppendOp() function?
Similarly, I'd like to add debug (file+line+column) info for all generated
objects.
Thanks in advance,
Christian.
