I rewrote/refactored almost the entire backend of #Emacs Reader to decouple parsing/rendering processes, make commands thread-safe and above all stop it from crashing in any manner.

We'd like more people to exhaustively test this PR, to ensure stability. If you wanna volunteer please test and report here:

This will be part of Reader's upcoming major release (0.4.0), and towards a stable foundation on which more UI features can be implemented.

We have finally finished a somewhat lengthy introduction to the new Canvas feature in #Emacs ! It's a self-contained post that will get you started on using the latest canvas feature. We also have really cool demonstrations both using Emacs Lisp and via dynamic modules.

Thanks to @tusharhero for all the reviewing, suggestions and improvements to our website setup. And also to @untrusem, @shepherd and @icy_thought for feedback, suggestions and ideas for what to do with canvas!

DOOM is finally available on Emacs ELPA!

M-x package-install RET doom-game RET

github.com/minad/doom-on-emacs

The port uses the new canvas feature we've added to Emacs 32.

#emacs #elpa #games #graphics

I finally made a new release of Futur, my #Emacs library for concurrency based on promises/futures.

The main new feature had been in it for months already but was previously hidden as "internal/experimental": it's the ability to run ELisp code concurrently, in a sub-process. Compared to other packages which offer this functionality (such as the Async or El-Job libraries), Futur aims for a much lower latency by re-using sub-processes (i.e. to avoid the startup delay incurred when launching new Emacs subprocesses). That should make it usable for interactive use-cases such as completion.

This re-use of subprocesses is fundamentally problematic because we need to isolate the side-effects of each use from each other. Futur does that by taking snapshots of the main obarray, which works well only when side-effects are limited to set, fset, ... and avoid setcar, aset, ...
The library has workarounds for the main known offenders (cl-defmethod and put).

Okay so, I cannot still believe it. But the #Emacs Canvas patch is finally merged to upstream master. It's been over 8 months of back and forth, and so much confusion and self-doubt, but it's surreal to see it finally be merged.

A whole new era of graphics within Emacs has opened up with this!

I am going to be forever indebted to @minad for collaborating with me on this, for coming up with the idea when he saw me struggle with PPM. He's been the best mentor to me through all this. This was my first patch to core, and it is through his guidance that I could get into the details of redisplay, etc.

I am also very thankful to @tusharhero @moksh @shepherd who did not give up on this while I was on it. Tushar has been so supportive with reviewing, and helping and in general keeping my hopes high.

All in all, I am very glad to be part of the Emacs community.

Cheers to Emacs, the editor that not only refuses to die, but evolves and lives!

If you're using #Emacs on Windows, we'd like your help in testing the Canvas patch. Follow the instructions and respond in the mailing list with your feedback:

(This is the last few things left before finalizing the patch!)

Created a starter Emacs configuration to work with Guix!

Thanks to the parinfer Lisp editing approach, I think it's possible to create a configuration that's usable for newcomers unfamiliar with Emacs, Scheme and Guix.

Currently the configuration is in its very early stage, feedback and contribution welcome!
