wiki page for 'how to change default font'

-----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.

Sending UDP broadcasts
by Christian Kellermann 04 Feb '22

04 Feb '22

Dear List, I am trying to send a UDP broadcast on a Linux host with the following code: ``` s := Socket newUDP. s setOption: 'SO_BROADCAST' value: 1. [[(Delay forSeconds: numberOfSeconds) wait. s sendUDPData: shoutout toHost: '255.255.255.255' port: (self portNumber) ] repeat] fork. ``` I always get a Primitive Failed error for the sendUDPData message. shoutout is a string in this case. What am I missing for this example? Versions used are: Squeak5.3 latest update: #19470 unix linux-gnu x86_64 Open Smalltalk Cog[Spur] VM [CoInterpreterPrimitives VMMaker.oscog-eem.3142] Unix built on Feb 4 2022 08:41:04 Compiler: Clang 13.0.0 platform sources revision VM: 202201220125 Kind regards, Christian -- May you be peaceful, may you live in safety, may you be free from suffering, and may you live with ease.

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.
