p.3 simpliciyty -> simplicity p.4 we will have the define their semantics. -> to define ? I am not sure I understand the sentence p.10 and may converted on the fly -> and maybe ? I am not sure I understand the sentence At the beginning I started to read and understood nothing, then I read a 24 slides lecture on lisp lists [1], then I restarted to read and understood One of my main problem was that what cdr does is explained p.7, while cdr is used p.3 for the first time and multiple times before p.7. But maybe you expect the reader to know scheme already.

Re: [Pharo-users] Pharo sound with SDL Library

Hi mariano did you try the sound package that is on Smalltalkhub/Pharo? or PharoExtras.

MiniScheme in Pharo

Hi I finally decided to release the booklet I wrote about implementing a minischeme in Pharo. I did not announce it yet because I would like to get feedback and fix what can be fixed. https://files.pharo.org/books-pdfs/booklet-AMiniSchemeInPharo/2018-03-17-Mi… Stef

If you're not attached to SDL, maybe this minimal wrapper of the cross-platform FMOD library would help: http://smalltalkhub.com/#!/~SeanDeNigris/FMOD . IIRC I used it to play mp3 files, but only tested on Mac and will have to be ported from NB to uFFI. Also, how did you install Pharo Sound? ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Pharo sound with SDL Library

by Mariano Badoglio

Hello! I need to use the Pharo Sound over Ubuntu platform, but I couldn't get it work. I tryied sending the parameter vm-sound-OSS and vm-sound-ALSA to the vm but I get no results. I am now trying to use the SDL Library. I could initialize the sound SDL_Init(SDL_INIT_AUDIO), very similar to initializing video, but when trying to use the SDL_LoadWAV, it needs a SDL_AudioSpec data type and I do not know how to do it. I tried to use an Structure as parameter but with no result, I couldn't found any similar example to follow. I will appreciate any help or tips on this. Thanks in advance. Best regards, Mariano.Â

Re: [Pharo-users] confusion about GTFilter hierarchy and GTFilterSubstring

by Tudor Girba

Hi, I am not sure I understand the confusion. The filter is a strategy used to select objects. GTFilterSubstring filters based on finding the input string as a substring in the string representation of the objects. You do not see a difference because by default, the logic is a substring matching one.

Re: [Pharo-users] Packaging question

by Stephane Ducasse

Ok I will go for the compile time and remove the package so that this is even more stupid to manage.
