wiki page for 'how to change default font'
by stes＠PANDORA.BE 07 Jul '22

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 How to change the system font to a custom TrueType font ? I managed to solve with the help of the following: http://wiki.squeak.org/squeak/5586 http://wiki.squeak.org/squeak/5584 http://wiki.squeak.org/squeak/5773 - system with russian (cyrillic) fonts The above documents helped a lot; specifically the document 5773 "how to setup Squeak with a cyrillic font", had an important note: "Switch your fonts This can be done from World->Appearance->System Fonts." That works indeed, if you set the various fonts (text font, menu font, list font, code font etc.) in the World->Appearances->System Fonts. I think this could be in its own wiki page: "How to change the default System Fonts" if such a doc does not already exist. I didn't find it on wiki.squeak.org but fortunately the other docs helped.

Help with FFI
by Christian Kellermann 04 Feb '22

04 Feb '22

Dear list! I want to find my way around the FFI module and how to use it in squeak. No let's step back. I want to use a a binding to libsodium form Tony (https://www.eighty-twenty.org/2013/06/11/nacl-for-squeak-and-pharo) and ended up using the Crypto-Nacl-HernanMoralesDurand.13.mcz package as the most recent one from Tony seemed to be Pharo's FFI syntax, as Tobias suggested to me. However each of the supplied tests return a 'module not found error' on my 64 bit Linux Squeak 5.3+updates with the bundled VM. So I tried the Unix examples there and none of those work either, so before I dig deeper into this I'd like to get some kind of re-assurance of what I should expect to work on this particular setup. The FFI Tests from the bundled package all pass though. So my questions are: 1. Are the Unix FFI examples supposed to work? 2. Is the Crypto-Nacl package I want to use recent enough for the FFI? 3. Is the documentation in swiki still up to date for squeak 5.3? 4. What's the logic for searching and loading the shared object to bind to and where do I have to look in the opensmalltalk-vm code? Thanks for all your help! Christian -- May you be peaceful, may you live in safety, may you be free from suffering, and may you live with ease.

TelegramSmalltalkBot

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, I've seen a demonstration by Christoph Thiede of a TelegramSmalltalkBot. I'm using OpenIndiana (UNIX) with the cog-spur VM using Squeak6.0alpha-20532 64bit. #pkg list -v cog-spur runtime/smalltalk/cog-spur(a)5.0.2957,5.11-2020.0.1.1 I don't know whether I understood the demo correctly, but my understanding was that is is possible to send Telegram messages from Squeak. I'm trying to find out whether this works on OpenIndiana. Following instructions at 'Self hosting the bot' at: https://github.com/LinqLover/TelegramSmalltalkBot First of all, step 1 works (I think it works, see screenshot): Metacello new baseline: 'TelegramSmalltalkBot'; githubUser: 'LinqLover' project: 'TelegramSmalltalkBot' path: 'src'; load. As a remark, because I'm a total absolute beginner with this, I had to figure out "Install the latest Trunk updates in your image": The way to do this seems to be: a) in the Squeak menu update Squeak this upgraded my Squeak6.0alpha-20532 to Squeak6.0alpa-20533 64bit from a Workspace perhaps: TheWorldMainDockingBar updateSqueak. or MCMcmUpdater updateFromServer. b) run in a workspace : Installer ensureRecentMetacello I'm just adding this as a remark because without the ensureRecentMetacello, the instructions given complain 'no selector githubUser:project:path:'. I think this because it is assumed that you first run ensureRecentMetacello, or otherwise have Metacello loaded in your image. Because I'm unfamiliar with Metacello, I'm just adding this remark. Anyway Metacello seems to load, and then it proceeds loading SimulationStudio-Base-cypress and finally TelegramSmalltalkBot-Tests-cypress. My question now is how to proceed. Can I run some tests at this point to check that the Metacello install of TelegramSmalltalkBot was succesful ? Thanks!

Send super to trait?
by Thiede, Christoph 17 May '21

17 May '21

Hi all, I just was trying to activate a super method from a trait but got a DNU: MyTrait >> #foo ^0 Object subclass: MyObject uses: MyTrait. MyObject >> #foo ^super foo + 1 Is this not how traits are expected to work? Or is there any other way to reuse the default logic specified in the trait? Do I need to return to traditional inheritance in order to achieve this? Thanks in advance! Best, Christoph <http://www.hpi.de/>
