Hello guys,
first of all I want to thank you everyone here for the help provided in
the past.
Now let's come to the point: I wish you could provide me some links
where the ANTLR ast trees and options are well described.
Particularly
loop_cond
: SEMICOLON!
{ #loop_cond = #([NULL_NODE, "null_cond"]); }
| expr SEMICOLON!
;
{ #loop_cond = #([NULL_NODE, "null_cond"]); }
the meaning of this kind of expressions.
I know the meaning of '!' or ^ or when there's nothing next to a rule.
But I haven't got yet the meaning of that expression.
If anyone could explain me it into detail or send me the link to a web
page that explains it step by step as I'm a newbie in these things that
would be great.
Thank you everyone for helping me.
