Hey, wait a minute. I think I made a mistake.

You modified the regular expressions, from \* to *.
Also, you are calling an extra parse_ctype(ret, tymap) instead of just TYPE_VOIDP.
Probably better to keep such call inside the case statement: [parse_ctype($1.strip, tymap), $2, $3].

Fixed.
@Maumagnaguagno I appreciate the help.

I guess you need to propagate tymap to parse_ctype to avoid creating a new Hash in tymap ||= {}.

Yes, I think you're right.
But this is the first time I've sent a PR to Fiddle.
I think I'll leave it as is and see what the project owner has to say about it...

Anyway, thank you again.

I went back to work on the monkey patch one more time, but it wouldn't work without passing the tymap 🤦
I have to fix it. Maybe we should add a test for typealias...

I wanted to parse_signature recursively when the argument was a function (i.e. a function pointer).

Could you show a signature you want to parse?

An example: void uiSpinboxOnChanged(uiSpinbox *s, void (*f)(uiSpinbox *s, void *data), void *data)

Yes, thanks.
I would like to create a customized method. When you pass a block to that method, it will create a Fidle::Closure::BlockCaller with the appropriate type. To do this, each function needs to know the type information beforehand.

Idea:

We use [TYPE, SIZE] for sized array type. e.g.: [Fiddle::TYPE_CHAR, 80] for char x[80]

It may be a good idea that we use [Fiddle::TYPE_VOIDP, RETURN_TYPE, [ARGUMENT_TYPE, ...]] for function pointer. e.g.: [Fiddle::TYPE_VOIDP, Fiddle::TYPE_VOID, [Fiddle::TYPE_VOIDP, Fiddle::Type_VOIDP]] for void (*f)(uiSpinbox *s, void *data)
