We currently have a problem which is all selectors are assumed to have
the same method effect. The problem is we can have method collisions,
for example:
NSObject.load is { void { id SEL } }
NSBundle.load is { char { id SEL } }
So, this inferred wrong:
IN: scratchpad [ NSBundle -> mainBundle -> load ] infer .
( -- )
But now we can do this instead:
IN: scratchpad [ NSBundle -> NSBundle.mainBundle -> NSBundle.load ] infer .
( -- x )
It doesn't really fix the original problem, but its a way to workaround
it and added ``method-collisions`` to report on the conflicts.
If a method doesn't exist we need to provide a signature so the stack is balanced. This should also allow deploying from macOS versions that do not contain methods to ones that do. This is an alternative to asking a class if it provides a selector.
alien-invoke gets an extra parameter indicating if the call uses varargs
or not. In 99.9% of the cases, the parameter should be f, but is t if
varargs are indicated. E.g
: do-printf ( fmt d -- st ) int f "printf" { c-string double } t alien-invoke ;
Specifically,
• Created >c-array to be replacement for >T-array.
• Created cast-array to be generic replacement for all T-array-cast words.
• Created c-array@ to be generic replacement for T-array@ words.
• Replaced usages of <T-array> with T <c-array>
• Replaced usages of <direct-T-array> with T <c-direct-array>
• Replaced usages of >T-array with T >c-array
• Replaced usages of T-array-cast with T cast-array
• Replaced usages of malloc-T-array with T malloc-array.
• Removed malloc-T-array.
• Removed T-array-cast.
• Removed T-array@.
• Removed >T-array.
I also added (but didn't change any code to use):
• T c-array-type, returns T-array
• T c-array?, returns T-array?
• c-array{ T ... }, returns T-array{ ... }
Bootstraps just find on Mac OS X. Also `load-all test-all` works for me.
- Replace hand-written specialized-arrays.* subvocabularies with new system; instead of USE:ing specialized-arrays.T, do SPECIALIZED-ARRAY: T
- Ditto for specialized-vectors; use SPECIALIZED-VECTOR:
- io.mmap.functor: removed entirely, use <mapped-array> instead
- struct-arrays and struct-vectors have been removed because specialized arrays and vectors subsume them entirely
