Hi All,

I've released csound-vscode-extension 0.7.0 that has an initial
implementation of rendering Csound in the browser when used as a web
extension.

This means that if you have a github repo with a csound project, you
can open that in github.dev, install the csound extension, then render
your project in-browser. You'll get a web panel on the left tab that
shows up when you use the "Csound: Play Active Document" command.
You'll need to start the audio context to audio going using that
panel, and you can use the play/pause and stop buttons to control
Csound.  You should be able to live code using this extension in the
web browser.

There's some quirks that were required to get this to work. The
extension copies all files in VSCode's file system into Csound's
in-memory FS. This works fine with a small repo, but if you have a
large amount of data in your repo it will try to copy all of that into
memory so be aware of that.

The goal here is to leverage github for project management, while also
having the convenience of zero-install for working with Csound.
(Hopefully works out for all the academics out there dealing with
locked down computer labs! ;) ).

All best,
steven

Thank you, Steven. Again and again and again! Wow, this will be such a big help as more and more of my students and I’m sure students everywhere are wanting to use the browser to deploy their work with Csound. I. I have a student right now who is working with your live coding system and studying it and building a big project on it. studying all your examples ( thank you ) It will be an additional inspiration for them.

This is a really interesting approach. Does it require VS Code to be installed?

Glad you got it going there!

Also, also managed to publish the vscode extension to the OpenVSX
marketplace, which is used by non-vscode editors in that ecosystem
(e.g., Cursor, Windsurf).

It was very easy to set up - install the extension and then it runs.

A good alternative to coders. I think the WebIDE is probably easier for novices, but this is pretty good for more advanced users.

There's some nice things that come for pedagogy from using github
repos. I can imagine setting starter projects with instructions for
each exercise that students can fork, develop, commit to their fork,
and submit a PR as a means to "turn in" their work. (I also think it's
valuable for students to learn project versioning for art work early
in their lives, to have a history they can draw upon for themselves
and others, but that's me on a soapbox :P.)  But I agree that novices,
especially those without a lot of programming background, may find the
webIDE an easier entry point.

Hi Joachim,

I think it's fine to quote and use as part of a news post.

Thanks!

if you have corrections, we can modify, of course.

(Note: I realized a number of messages from both user and dev lists
were routing to my spam folder, so I've apparently been missing
messages for a while)

I'm not sure how to work out a start button into the UI that makes
sense within the UX of VS Code. That said, I will keep this in mind
for future iterations. Also, I tend to use cmd-shift-p (think it's
ctrl-shift-p on other OS's?) to open up the command palette and then
use the "Csound: Play Active Document" command. I suppose it's second
nature for me as I use VSCode-type editors a large part of my day and
use the command palette often. I find it easier to use than
remembering the keyboard shortcut.

Wow, this will be such a big help as more and more of my students and I’m sure students everywhere are wanting to use the browser to deploy their work with Csound. I. I have a student right now who is working with your live coding system and studying it and building a big project on it. studying all your examples ( thank you ) It will be an additional inspiration for them.
