Any reason to pass as a flat collection of pairs rather than a collection of associations or a dictionary? IMHO the former is less intention revealing and potentially confusingâ¦ ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Standalone HTML Model

I'd like to create HTML via a DSL, like Seaside's canvas builder, but without loading a whole web framework. Any ideas? ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

UFFI problem / doubt
by alvaro piorno Sept. 19, 2017

Sept. 19, 2017

Hi everybody, iÂ´m using UnifiedFFI with Chipmunk2D library . I want to get a pointer to a C Structure (cpBody) and set a position to it. I have a subClass of FFIOpaqueObject to handle pointer. This is the "new " ffiCall : self ffiCall: #(cpBody* cpBodyNew(cpFloat m, cpFloat i)) And this is a "seter" ffiCall: self ffiCall: #( void cpBodySetPosition( self, cpVect vector ) ). I`m not getting any "error" but the position is not updating. I tried the same using Chipmunk directly and it works, so there is a problem with what i have in Pharo. Any suggestion? Thanks in advance. Alvaro Piorno
