Re: [Pharo-dev] [squeak-dev] valid pragma syntax

Hi Nicolai, On Sun, Jan 10, 2016 at 3:16 AM, Nicolai Hess <nicolaihess(a)gmail.com> wrote: > pharo fogbugz issue: 17359 MessageNotUnderstood: receiver of "keywords" is > nil > > > is this valid pragma syntax: > > <apicall: bool 'SetCursorPos' (long long) module: 'user32.dll'> > As others have said this is not a valid pragma. A valid pragma is a message expression (a message with no receiver) that has only literal arguments. There is one exception, to accept a variable name for the error code in a primitive invocation. And as Levente has said it is a goal of the new FFI to get rid of the old syntax you show above. And as Igor Stasenko discovered /any/ C signature can be written as a literal Array, providing we allow underscores in Symbols (which is a preference). So for example, the heapsort declaration from the standard C library: int heapsort(void *base, size_t nel, size_t width, int (*compar)(const void *, const void *)) could be written as a pragma via e.g. <ffiCCall: #(int heapsort(void *base, size_t nel, size_t width, int (*compar)(const void *, const void *)))> in which case it is equal to <ffiCCall: #(#int #heapsort #( #void #* #base #, #size_t #nel #, #size_t #width #, #int #( #* #compar ) #( #const #void #*, #const #void #*)))> which, while a massive hack, is pretty neat. The only difficulty in parsing the above s that void *, is #void #*, not #void #* #,. So for me, the natural pragma syntax for the new FFI should be a single keyword starting with ffi that includes the language with which to parse the pragma's argument, followed by a literal Array containing the signature (rather than e.g. a String). I'd also provide a special-purpose pretty-printer for literal arrays that would be used to pretty-print the above, e.g. when decompiling. This would easily allow extensions such as <ffiCcall: #(wchar_t * wcschr(const wchar_t *s, wchar_t c)) arg1is: #UnicodeString arg2is: Character> to guide a marshalling engine in providing automatic checks and conversions. [Slightly OT] Note that I'm already using this syntax in Alien callbacks because one thing it does is to normalize the signature, eliminating the significance of most whitespace (the #*, above being one example where it fails). So a Callback for heapsort above looks like voidstarvoidstarRetint: callbackContext sp: spAlien <signature: #(int (*)(const void *, const void *)) abi: #IA32> ^callbackContext wordResult: (block value: (Alien forPointer: (spAlien unsignedLongAt: 1)) value: (Alien forPointer: (spAlien unsignedLongAt: 5))) or voidstarvoidstarRetintARM32: callbackContext sp: spAlien <signature: #(int (*)(const void *, const void *)) abi: #ARM32> ^callbackContext wordResult: (block value: (Alien forPointer: (spAlien registerAt: 1)) value: (Alien forPointer: (spAlien registerAt: 2))) Hmmm, if Callback had subclasses for each ABI then the above would become IA32Callback methods for signature voidstarvoidstarRetint: callbackContext sp: spAlien <signature: #(int (*)(const void *, const void *))> ^callbackContext wordResult: (block value: (Alien forPointer: (spAlien unsignedLongAt: 1)) value: (Alien forPointer: (spAlien unsignedLongAt: 5))) ARM32Callback methods for signatures voidstarvoidstarRetint: callbackContext sp: spAlien <signature: #(int (*)(const void *, const void *))> ^callbackContext wordResult: (block value: (Alien forPointer: (spAlien registerAt: 1)) value: (Alien forPointer: (spAlien registerAt: 2))) Much nicer.

But, I was not arguing. I just said why we chose to add it where it is. However, in Glamour the rule is that we have global actions as buttons, and contextual ones as contextual menus. This is used consistently in the inspector and playground, and it can be used as consistently to the debugger as well :). > Even so we (smalltalkers) have the best software environment (Pharo) we are bound to our owns > habits. > And it is a question of "discoverability". If you only see 5 debugger action icons, you > may not know that there is another one (hidden) inthe context menu. I am convinced it is the habits. Just consider this. The contextual menus of the spec debugger have several dozen actions. Also, the previous inspector had no visual actions. You see, if we would have such a strong set of design principles, we would have seen it. One goal with GT is to provide a small set of conventions that you can learn. They are clearly not the best, but once they are adopted in every tool, it should be better than the current state of affairs. And then we can iterate, but my stand is that we first have to reach a uniform enough situation. Anyway, I do not want to have a religious debate. But, I also think that if we impose the condition that new things should be exactly like the old ones we have a high chance of staying the same forever :).
