hello chuckians chuck does not seem to be able to see wireless keyboards on linux. Any suggestions ? Most of my computers do not have wired keyboards. And why do all these other things like PC Speaker show up as keyboard devices? thanks,d chuck --probe shows this chuck]: ------( 10 keyboard devices )------ [chuck]: [0] : "Dell WMI hotkeys" [chuck]: [1] : "HDA Intel Front Headphone" [chuck]: [2] : "HDA Intel Line Out" [chuck]: [3] : "HDA Intel Line" [chuck]: [4] : "HDA Intel Mic" [chuck]: [5] : "HDA Digital PCBeep" [chuck]: [6] : "PC Speaker" [chuck]: [7] : "HDA ATI HDMI HDMI/DP,pcm=3" [chuck]: [8] : "Power Button" [chuck]: [9] : "Power Button" [chuck]: on my laptop the keyboard shows up [chuck]: ------( 12 keyboard devices )------ [chuck]: [0] : "HD-Audio Generic Headphone" [chuck]: [1] : "HD-Audio Generic Mic" [chuck]: [2] : "HDA Digital PCBeep" [chuck]: [3] : "HD-Audio Generic HDMI/DP,pcm=7" [chuck]: [4] : "HD-Audio Generic HDMI/DP,pcm=3" [chuck]: [5] : "Ideapad extra buttons" [chuck]: [6] : "Lenovo Yoga Tablet Mode Control switch" [chuck]: [7] : "PC Speaker" [chuck]: [8] : "Power Button" [chuck]: [9] : "Lid Switch" [chuck]: [10] : "Video Bus" [chuck]: [11] : "AT Translated Set 2 keyboard"

New audio programming environment released
by Robin Haberkorn 21 May '24

21 May '24

Dear ChucK users, I just released my own new audio programming environment. It draws some inspiration from ChucK, but really throws a lot of well-established concepts in the world of real-time audio programming out of the window: first and foremost the patch graph and the audio/control-rate dualism. All number crunching is in a Lua, so a dynamic scripting language. It's made possible by LuaJIT, ie. JIT compilation. Hard to explain really, without a lot of prose. Documentation is still lacking. My master's thesis about this project will be released soon as well, but it will be in Russian. Anyway, I think this little project is at least a fun experiment. Whether it will really change anything in the world of audio programming is questionable. Here's the website and repository: https://rhaberkorn.github.io/applause2 https://github.com/rhaberkorn/applause2 I would be happy to hear some feedback - both in trying to run my code and regarding my design choices (as far as they are understandable, considering the lack of introductory material at this point). Best regards, Robin

Native Vim/Neovim filetype and syntax soon available :)
by Andrea Callea 26 Jan '24

26 Jan '24

Hi all, I just want to share that Vim and soon Neovim (0.10) now have native .ck filetype detection and native syntax highlighting. I accidentally became the official maintainer as a byproduct of developing a chuck-nvim plugin out of a personal need. - PRs: https://github.com/vim/vim/pull/13888 - https://github.com/vim/vim/pull/13895 - Repo for any syntax issue/addition feedback: https://github.com/gacallea/chuck.vim - The plugin, should you be curious: https://github.com/gacallea/chuck-nvim/ The plugin mimics Webchuck UI and functionality. Not 100% clone as this was my very first time with both developing a plugin and Lua. I tried my best but I had to stop adding some features 'cause noob. If you try it, I'd be curious to know what you think. Enjoy :) — Andrea Callea https://gentlewashrecords.com Sent with Proton Mail secure email.

chuck and HID devices
by d 02 Nov '23

02 Nov '23

Hello chuckians, I'd like to experiment using a HID device (wireless logitech keyboard) to send midi CC events,OSC etc. But Chuck does not see my keyboard. chuck --probe reports all sorts devices as keyboards like headphones and mics but no logitech keyboard. The strange thing is that the mouse works and on a keyboard with a trackpad but I cannot open the keyboard on the same device. Any ideas? chuck version: 1.5.1.3 (chai) Linux | 64-bit audio drivers: ALSA | PulseAudio | JACK http://chuck.cs.princeton.edu/ http://chuck.stanford.edu/ ----------------- [chuck]: ------( 10 keyboard devices )------ [chuck]: [0] : "HDA Intel Front Headphone" [chuck]: [1] : "HDA Intel Line Out" [chuck]: [2] : "HDA Intel Line" [chuck]: [3] : "HDA Intel Mic" [chuck]: [4] : "HDA Digital PCBeep" [chuck]: [5] : "HDA ATI HDMI HDMI/DP,pcm=3" [chuck]: [6] : "Dell WMI hotkeys" [chuck]: [7] : "PC Speaker" [chuck]: [8] : "Power Button" [chuck]: [9] : "Power Button" thanks, d d

New version of ChucK VSCode extension
by Forrest Cahoon 22 Sep '23

22 Sep '23

Hey all! I've just updated my VSCode extension https://marketplace.visualstudio.com/items?itemName=forrcaho.chuck . I never realized that playing the file in the editor never worked under Windows; now it does. Syntax highlighting has been fixed to work with 1.5.x (I should make it clear, it's broken under older versions of chuck; I didn't see a great demand for backwards compatibility). That's something that also never worked under Windows, but now does. The syntax checking is turned off by default, because if you have multi-file projects you'll get syntax errors about things defined in a file meant to be included earlier with Machine.add at runtime. (I'm soliciting ideas about how to fix this!) Oh, yeah, I updated the syntax highlighting so Chugraph is recognized and Chubgraph no longer is. Please give it a spin, let me know if you have issues, and leave ratings/reviews on the VSCode Marketplace site if you like it.

chuck-1.5.1.0 (chai) released
by Ge Wang 11 Aug '23

11 Aug '23

Dear all, chuck-1.5.1.0 (chai) has been released: https://chuck.stanford.edu/release/ WebChuck & IDE have also been updated to 1.5.1.0: https://chuck.stanford.edu/webchuck/ https://chuck.stanford.edu/ide/ what's new? (full release notes) https://chuck.stanford.edu/release/VERSIONS =============== Some highlights =============== This release (1.5.1.0) updates a long-standing policy regarding `return`statements in function declarations (see below); added @array.sort(); added new command-line option (--pid-file), useful for process monitoring in long-running installations; general bug fixes and stability improvements. --- NEW: the chuck compiler now rejects non-void function definitions in which not all control paths return a value, and will print a compiler error in the form of: "error: not all control paths in 'fun int f()' return a value" RATIONALE: while *** this may break some existing code (apologies!) *** that assumed the previous return semantics (or forgot to return a value or accidentally declared a function as returning something when it should return `void`), we believe this change will be more beneficial in the long term and will lead to clearer, more intentional code. --- FYI much has been added recently between 1.5.0.0 and 1.5.1.0: * new for-each loop syntax for iterating through arrays (1.5.0.8) * enhanced and more accurate compiler error reporting; now highlights code and pinpointing error location in code (1.5.0.5) * detection and reporting for out-of-order dependencies (1.5.0.8) ...the cause of much mysterious behavior and crashing previously * color terminal support for CLI chuck (1.5.0.5) * expanded class library support in IO, random number generation, Machine.eval(), chugins management, and array * new features in CLI chuck, miniAudicle, WebChucK & IDE * (developer) streamlined c++ integration for those wishing to incorporate ChucK core into other c++ hosts (1.5.0.7) https://github.com/ccrma/chuck/tree/main/src/host-examples Our work is never done. Here's to supporting research, teaching, and art-making.
