Name: VMMaker.oscog-eem.2785 Author: eem Time: 31 July 2020, 7:45:15.985473 pm UUID: 9fa77ef1-7255-47f3-9dd1-c500f9529cbb Ancestors: VMMaker.oscog-eem.2784
Plugins: Clean up the SoundPlugin, eloiminating almost all cCode:'s, making it potentially simulateable once the internal API is implemented. Use the methodRetur...: API to simplify a number of primitives. Change primitiveSoundEnableAEC to take either 0, 1 or a boolean.
Slang: eliminate the arguments to addressOf:put: blocks via nodeIsDeadCode:withParent:
Simulation: implement unsigned coercion in cCoerce:to: to support this form in primitiveSoundEnableAEC (interpreterProxy isIntegerObject: (arg := interpreterProxy stackValue: 0)) ifTrue: [arg := interpreterProxy integerValueOf: arg. (interpreterProxy cCoerce: arg to: #unsigned) > 1 ifTrue: [^interpreterProxy primitiveFailFor: PrimErrBadArgument]. trueOrFalse := arg = 1] ifFalse: [(interpreterProxy isBooleanObject: arg) ifFalse: [^interpreterProxy primitiveFailFor: PrimErrBadArgument]. trueOrFalse := interpreterProxy booleanValueOf: arg].

Use the methodRetur...: API to simplify a number of primitives.
Ooh, I like that change.
But it needs to be read in a "Bobby Llewellyn making silly voice" to really get the effect. If you don't know Bobby Llewellyn you need to a) watch some Red Dwarf b) watch some recent 'Fully Charged' episodes on yootoob in order to get the reference and style.

Cool. I've seen people asking about higher bit depth in Sound plugin. Maybe that will be easier to add now ?
Best, Karl

Plugins: Clean up the SoundPlugin, eloiminating almost all cCode:'s, making it potentially simulateable once the internal API is implemented. Use the methodRetur...: API to simplify a number of primitives. Change primitiveSoundEnableAEC to take either 0, 1 or a boolean.
Slang: eliminate the arguments to addressOf:put: blocks via nodeIsDeadCode:withParent:
Simulation: implement unsigned coercion in cCoerce:to: to support this form in primitiveSoundEnableAEC (interpreterProxy isIntegerObject: (arg := interpreterProxy stackValue: 0)) ifTrue: [arg := interpreterProxy integerValueOf: arg.
