Controlling callback time in Parser.pm

Thanks for the great tools.

I’m trying to use the Verilog::Parser and Verilog::SigParser to process my verilog RTL files. I notice that the callback subroutines will be executed when $parser->eof () is called. Is there a way for a user to change the behaviors of the callback subroutines so that it would be executed immediately after a line is parsed by $parser->parse()?

Thank you.

It does all parsing at the end because it's several times faster, I'd strongly encourage you to use it that way if you can; for example if you're grabbing other text you could look at the file again using ->filename and ->lineno.

Anyhow, you can call eof multiple times if you want, for example in the loop in parse_file in Parser.pm, it'll parse everything unparsed up to that point.

Thank you for the reply.

The reason I would like a immediate execution of the callbacks is that so I can use regexp to substitute the line parsed by ->parse() on the spot without coming back to it later.

Anyways, your suggestion works and I'm actually doing just that. It just means that I have to collect all the information in the overloaded callbacks then process the file the second time.

Thank you again for your attention. Your tools make my project possible.
