Manfred,

Could I make a small request for line comments in Joy? I for one would
find them really useful for temporarily removing lines of code during
development. Especially where they already contain block comments.

My preference would be '#' for this purpose, only because it is used
by so many other interpreted languages, and because it fits well with
unix scripts headed with '#!/usr/local/bin/joy'.

A small request and only a small change required to scan.c:

112a113,117

Of course this also means you can remove the little hack on lines
141-144 of main.c :-)

Regards,

Nick.

This is in my opinion really a very good idea.

BTW: Joy is one of the few languages where word comments wold make sense.

Yes, a similar request was made a long time ago, I think.

Done. See the Joy web page.

I removed those lines, too, as you suggested. But since I am not at all
familiar with command line interpretation, I would like someone to
have a good look at what I've done. (John Cowan - are you still there ?)

Thanks.

Yes. There's no problem: command line interpretation is being done
in the kernel, so the only thing Joy has to do is ignore lines
beginning with "#". Handling this in a general way suits me fine.
