Compatibility

SharpMUSH does away with some of the more unique aspects of PennMUSH parser curiosities.

Unbalanced Parenthesis

In PennMUSH, the following is legal, while is not in SharpMUSH:

PennMUSH

think add(1,2
> 3

Instead, complete the parenthesis.

SharpMUSH

think add(1,2)
> 3

Full Recursion Parsing

In PennMUSH, TinyMUX, etc, you can do the following:

PennMUSH

&fn me=ucstr; think [v(fn)](foo)
> FOO

Instead, use callfn() to call the intended function.

SharpMUSH

&fn me=ucstr; think callfn(v(fn),foo)
> FOO

This is an awesome feature of MUSH-likes, but we explicitly do not support this, as it makes the parser non-deterministic, ambiguous and harder to maintain. Most existing Softcode does not rely on this behavior however.

Note

SharpMUSH introduces callfn() and @callcmd to replace this loss, which ensures most scenarios have a way to build the compatibility back in.
