apheleia VS perspective-el

For black, I can recommend apheleia. It handles not only black but also all the other common formatters (not only for Python), with custom ones being relatively easy to add.

1.projectile-kill-buffers or the built-in project-kill-buffers will do that for the current project. You could run that before switching projects.

2. https://github.com/radian-software/apheleia

3. There might be a way to do this but I'm not sure. Emacs being inherently single threaded probably makes this difficult. But yes, I use M-x (re)compile.

4. libvterm is the best still imo. You can definitely do multiple instances and there's even different tab modes in Emacs now.

I forgot to mention a third option namely lassik/emacs-format-all-the-code and there are efforts to combine/consolidate the three into a single package which would be great.

I use formatters in order to automatically format source code on save. Personally I use apheleia for this. It requires clang-tools installed as it uses clang formatter.

Generally speaking, emacs does only so much for indenting those mixed mode files, so you might want to use a dedicated JS(X)-formatter (default one would be prettier). I can recommend integrating it using apheleia. It automatically prettifies buffers on save, but without having your cursor jump around like prettier-mode does. It also relies on having the prettier script available (from npm i -g prettier or its likes).

I opened a ticket https://github.com/nex3/perspective-el/issues/198 but can’t promise to get around to it soon.

I have tried to get this behaviour for a while. The closest I have gotten is using perspective.el, but it ended up being a bit clunky when I tried it like 4 years ago and now I just used bookmark+ which can save/load desktop files as bookmarks.

perspective for named workspaces.

persp-mode?

To scratch a personal itch, I created a little package that integrates perspective-el into the built-in tab-bar.

But I'm rethinking about my approach, as tab-bar-mode would give me nice visual help (#3), and it seems difficult to recover a perspective using perspective, and persp-mode may be a better fit in that sense (#4). The Treemacs integration isn't working for me either, and I get the same list of file trees for all perspectives -- I'm pretty sure I'm doing something stupid, but this was handled nicely with Doom Emacs's workspace support (#5). But perspective seems to work best for segregated buffer list (#1).

I think perspective.el is about what I’m looking for. If you had a list of org-ids, theses could be brought up in indirect buffers, and then those buffers added to the perspective group.

As for why this broke: this change went into Perspective a few weeks after Emacs 28 shipped. You either updated your packages recently after not updating for a while, or you switched to Emacs 28 (or later). Full discussion surrounding this change: https://github.com/nex3/perspective-el/issues/180

It sounds a bit like you want „perspective.el“ (1). It allows you to define „virtual workspaces“ of buffers with individual window layouts. On each virtual desktop the standard buffer list is replaced with a shorter showing only buffers belonging to the current context. I use it every day to keep „code“ buffers separate from my „test“ buffers.
