Re: [Pharo-users] FFI structs

by Thomas Bany

Hi Annick ! I'll explain first why you got the error. The assignment time: â05:45â failed because you tried to put an array of char (of size 5*sizeof(char)) inside an address. At some point, you need to allocate the memory that will hold the data. In your case, you can do it quite easily with the class-side method #fromString: of class NBExternalAdress. This will return a pointer, which you can assign to the field of your struct. Regarding what you really want to do, having a char[5] field in your struct, I'm not totaly sure how you can do it with NativeBoost. A C struc is just a chunk of memory with a well defined size, so if you want to specify a field as a char[5], you must have a type that match that size. It does not look like the field parser of NBExternalStruct can do it dynamicaly. You could maybe hard code it by subclassing NBExternalType into NBExternalArrayOf5Char, with a valueSize of 5. As a final word, be wary of where you have allocated your objects, whether it is in object-space (#new), or in C heap (#externalNew). The first is garbage collected so the address are volatile, but you bare the duty of freeing the memory in the second. 2014-10-29 12:18 GMT+01:00 stepharo <stepharo(a)free.fr>: > did you read the NativeBoost tutorial on the PharoForTheEntreprise book? > If you do please report potential mistakes so that we can improve. > > > > On 29/10/14 05:59, Annick Fron wrote: > >> I I have a C struct with a char* >> >> struct result { >> char* time } >> >> I define an ExternalStructure in FFI , with one field of type char* (note >> that the syntax char [5] is not accepted ! ). >> >> defineFields generates the accessors time and time: >> >> If I use >> time: â05:45â >> >> I get an error. >> How do I set a string value in an ExternalStructure ? >> >> Annick >> >> >> >> >> >> > >

Patterns are fairly global in nature, and they may match synonyms (i.e. methods of the same name but with different meanings), so I'm worried about the mastery of my changes. For an isNil ifTrue: to ifNil:, it's easy. But for an indexAt: to at: because I'm changing an internal API, I'd like a better preview of what it will affect before launching it (or a way to examine the resulting changes, which is a bit convoluted). > > >> One suggestion.

Re: [Pharo-users] Zoomable & Infinitely scrollable PasteupMorph

by Sean P. DeNigris

I gave up on zoomability (with the idea to revisit after Athens is integrated), but I hacked together an infinitely scrollable world, called ScrollableWorldMorph, which is in use in my LivingCode IDE prototype described (with loading instructions) at http://forum.world.st/Clickable-class-side-example-and-initialize-methods-i… If you have any questions about LivingCode specifically, the conversation was moved to http://forum.world.st/LivingCode-was-Clickable-class-side-example-and-initi… HTH ----- Cheers, Sean -- View this message in context: http://forum.world.st/Zoomable-Infinitely-scrollable-PasteupMorph-tp4778229… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

did you read the NativeBoost tutorial on the PharoForTheEntreprise book? If you do please report potential mistakes so that we can improve.
