Re: [Newbies] Sound, video and color in morphic projects
by Ricardo Pablo Salvador 30 Apr '20

30 Apr '20

Hi, I am Ricardo Salvador, and i am writing because i found the solution to one of the problems i asked for help about; maybe this will help someone else. It's about sound playing. In ubuntu the sound was not played in morphic projects and in the terminal I got the message "sound: /dev/dsp: No such file or directory". Since the "/dev/dsp" folder is part of the Open Sound System (which has not been included in Ubuntu for a long time), for Squeak to find it, it was resolved by installing "osspd" a package that emulates a daemon needed to make the "/dev/dsp" folder available.

SqueakMap is not responding
by TimKack 29 Apr '20

29 Apr '20

Hi all, Seems that ‘http://map.squeak.org/ping’ isn’t responding and thus making SqueakMap unusable. SMSqueakMap class >> findServer seems to iterate over map.squeak.org, map1.squeakfoundation.org, map2.squeakfoundation.org and finally 127.0.0.1:8080. I guess there are no mirrors since map.squeak, map1/2.squeakfoundation.org also points to the same server (104.239.229.92). Can someone give it a kick? Cheers, Tim -- Sent from: http://forum.world.st/Squeak-Beginners-f107673.html

Elegant way to tests an XMLElement's "string"`
by tty 20 Apr '20

20 Apr '20

Hi folks, I am writing SUnit tests for my PEG grammar and I am not fluent in Streams. I have my first test that checks the structure of an HTML UnorderedList. The output of the parse run is an XMLElement. *testListUnordered <timeout: 10> | xmlElement actor ios| actor := PEGWikiMediaGeneratorTables new. actor transcripton: false. xmlElement := parser parse: 'UnorderedList' stream: (self listUnordered) reading actor: actor. ios := ReadWriteStream on:''. xmlElement printOn: ios. self assert: ((ios contents) = '<ul><li> one</li><ul><li> two</li><ul><li> three</li><ul><li> four</li><li> four</li><ul><li> five</li><li> five</li><li> five</li></ul><li> four</li><li> four</li></ul><li> three</li><li> three</li></ul><li> two</li></ul></ul>') . * Is there a simpler way, minus the Stream to get the "contents" of the XMLElement? thanks in advance. -- Sent from: http://forum.world.st/Squeak-Beginners-f107673.html

Sound, video and color in morphic projects
by Ricardo Pablo Salvador 19 Apr '20

19 Apr '20

Hello! I'm Ricardo Salvador, from Rosario, Argentina. In 2008 I met Squeak-Etoys and was fascinated by it. Since then I use it in high school; I've been testing Squeak 5.x for a while and now with version 6.0: working with morphic-based projects is a fascinating and at the same time friendly way to start teens in programming. And in my experience I see that Squeak is really simple to learn with OOP principles. Now I try to learn SmallTalk. That's why I want to make a contribution-questions about Squeak 5.3 and/or 6.0 alpha: 1. On Linux Ubuntu 18.04 no sounds are played: when I try, the console gives the message "sound: /dev/dsp: No such file or directory". I haven't found a solution yet. In Windows it works. 2. The "Color" category is missing, containing the tiles "red", "green", "blue", "hue", "brightness", "saturation". The first three are very useful! 3. I can't get the camera monitor to work on Linux or Windows. On Linux I don't get any feedback from the camera. Those features still work ok in Etoys 5.0 although of course I would like to change to a current version of Squeak for its performance and validity improvements. I'm a teacher, specialized in computer technology applied to education. If I can contribute in other ways, I'm at your disposal. Thanks in advance! *Ricardo P. Salvador* http://tinyurl.com/rsatweb <http://tinyurl.com/cursosrps>

how to bring up a modal window?
by Ralph Boland 06 Apr '20

06 Apr '20

I need to create a modal window to which I will add a number of additional morphs. I did in an old project (Squeak 3.11 I think) that used classes MorphicDialogModel and MorphicMessageBox among others and so tried to port them to my Squeak 5.3 image. But these didn't seem to work. Perhaps I can track down the difficulties in getting these classes to work but perhaps the best thing for me to do is to not use them and create my modal morphs in the appropriate way for Squeak 5.3. But I don't know the right way to create a modal window using Squeak 5.3. Can someone inform me? Hopefully this is an easy question. Pointing me in the direction as to what/where I should read the right documentation would also be very helpful. Any help much appreciated. Ralph Boland
