Emacs on copy/v86 in your browser at https://play.emacsen.de/.

… fun?

Try it yourself: it’s slow.

Running M-x profiler-start/stop/report shows that read takes the most time when opening an Org-mode file (which takes a minute). Since v86 will try to JIT compile things, I guess currently v86 can’t handle those irregular control flows (goto) in read yet. But otherwise, for the non-Spacemacs versions, it seems OK when trying to run commands or switch themes as long as it doesn’t load tons of files.

• Run make to generate all the needed files (v86 file system & warmed-up state files).
• Run pnpm install and then pnpm build to generate the site.

Currently, it’s impractical to load a new Emacs session afresh in the browser because it will take forever. Instead, we pre-load Emacs into a v86 session and dump the VM states to be directly loaded back into browser sessions.

As is mentioned above, loading packages isn’t fast in Emacs under v86, so if you think pre-loading some modes can be helpful (if any people at all uses this “playground”, that is), you’re welcome to do so by:

• either modifying the states by editing Makefile,
• or adding a new state by editing Makefile and the <select> element in index.html.
