In my subclass of WASession for the application I store the current user and the language she wants to use. Date has #printFormat:, but only english #dayNames and #monthNames. I've just added my own. The javascript libraries for seaside all have custom components for date entry, looking much better than dateInput Stephan

Internationalization

Hello, IÂ´m using seaside & have some trouble regarding dates (displayed in English). WhatÂ´s the easy way to display dates in other languages? Particularly dateInput shows dates in English format (month, day, year) and months in English.

GDPR and the pharo website

by Bruce O'Neel

Hi, We're having some discussions on the Squeak side about GDPR and squeak.org. Â Are there any thoughts about changes to pharo.org for GDPR? Â We have similar web presences so one imagines similar issues. Â If GDPR is not ringing any bells you can startÂ [http://www.eugdpr.org](http://www.eugdpr.org), and the most interesting pages are probablyÂ [http://www.eugdpr.org/key-changes.html](http://www.eugdpr.org/key-changes.h… andÂ [http://www.eugdpr.org/gdpr-faqs.html](http://www.eugdpr.org/gdpr-faqs.html). Thanks. bruce

Re: [Pharo-users] Bloc Example Errors & question

by Ricardo Pacheco

Really impressive Alex, congratulations and thanks for the great work. Just as a feedback, I tried the examples again with a new image+bloc, under windows 10, and now most of the examples run but others still don't, like all the Animation, MobilePhone, Selectionand some in the Benchmarks. Thanks a lot Ricardo -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Hi Phil, I did that using Ronie's OpenAL binding and Merwann's wav parser back in 2014-2015: MCSmalltalkhubRepository owner: 'ronsaldo' project: 'OpenAL' MCSmalltalkhubRepository owner: 'MerwanOuddane' project: 'WAVParser' I did things such as (build yourself something derived from this code I did not check if it works): MyClass>>example WAVParser wavFromStream: ('resources/music/spellNoise.wav' asFileReference readStream binary readStream). contextAttributes := ALContextAttributes new. device := OpenALC openDefaultDevice. context := device createContext: contextAttributes asList. context process. context currentDuring: [ "Create the buffer" buffer := self makeBufferFromHeader: wav header data: wav data asByteArray. "Create the source" source := OpenAL genSource. OpenAL sourcei: source param: AL_BUFFER value: buffer. "Play the source" OpenAL sourcePlay: source. "Play for sometime " (Delay forSeconds: wav header soundDuration) wait. "Delete the source and the buffer" OpenAL deleteSource: source; deleteBuffer: buffer ]. OpenALC nullCurrentContext. context destroy. device close. MyClass>>makeBufferFromHeader: header data: data | buffer | buffer := OpenAL genBuffer. OpenAL bufferData: buffer format: (self readFormatFromHeader: header) data: data size: data size freq: header sampleRate. ^ buffer MyClass>>readFormatFromHeader: header ^ header channels = 1 ifTrue: [ header bitsPerSample = 8 ifTrue: [ AL_FORMAT_MONO8 ] ifFalse: [ AL_FORMAT_MONO16 ] ] ifFalse: [ header bitsPerSample = 8 ifTrue: [ AL_FORMAT_STEREO8 ] ifFalse: [ AL_FORMAT_STEREO16 ] ] I am pretty sure with a little work those things could work again. I have never succeeded in playing mp3 files from Pharo though (but I'm on mac and I remembered trying solutions that did not work on Mac but may work on other OS).
