quick question about verb_code on stunt

[d. kajsh]

On Lambda/GammaMOO with LambdaCore-17May04.db, verb_code(#123,
"foobar") produces a list of indented strings, while on Stunt with
LambdaCore-17May04.db, you need to call verb_code(#123, "foobar", 1,
1) to get that result. Is that intended behaviour?

I skimmed the git log since this seems to be a change in the built-ins
or argument passing, but I couldn't find any relevant commits that
could be the source of this change.

I believe this is to do with the lambdacore #0:bf_verb_code override. Don't have a standard lambdacore right now, but it's rather easy to change the verb in your new DB to change it back.

You're right, the different behavior seems to be due to the bf_verb_code override

in the stunt kernel package. I didn't even consider that.

What I meant to say was "while on Stunt with the LambdaCore package".

But as Stephen pointed out, it is in fact due to the bf_verb_code verb in the stunt kernel.

Since the server defaults to indented code listings

int indent = nargs < 4 || is_true(arglist.v.list[4]);

the stunt kernel should do so too, in my opinion.

Off hand, I don't remember why I defaulted it this way. I'll
investigate.

It turned out to be and error in the log.  I have attached a patch to
`#0:bf_verb_code()' and the entire code of the verb.  You should
either patch it or replace it:

That should have read "error in the _logic_".

And one more time as an attachment, since Groups mangled a line in the post...
