On: A few new things in Emacs 29

[josteink]

Emacs 29 contains so many things OOB that it has completely eliminated the use of 70-80% of the packages I use in my day-to-day job:

- use-package built in

- csharp-mode (now built in)

- typescript-mode (now built in)

- same with json-mode too.

- project.el instead of projectile

- eglot (now built in) over lsp-mode

As far as Emacs releases goes this one has more functionality packed than I can remember in any previous release ever.

I already use use-package, so that's great... I also use projectile and it's been working great... how should I prepare to move to project.el? Are there any guides? Or things just work the same I am used to, and I just need to delete projectile once upgrading?

I also use lsp-* for all IDE features... is eglot going to be the better choice here for every language?? LSP works with Go, Dart, Java, Zig, Rust, Lua... do I need to remove all my config for those to use eglot??

I recently switched from projectile to project and I noticed essentially zero changes. If you're not doing anything particularly custom you might not even notice.

I tried switching to project.el, but eventually decided it's too bare-bones for me.

As far as I'm concerned, project.el lacks the following features OOTB:

1. Something like the .projectile file to mark a folder as a project (without VCS).

2. Support for ag, rg and vterm.

3. Register new project types (to customize configure commands, compile commands, etc.)

4. Regenerate tags.

5. The ability to find the "other file" (x.h <-> x.c) across the project.

And this list is incomplete! So if you rely on any of the above, I suggest not migrating to a project.el-only setup.

eglot is just another (awkwardly named) lsp-client. It uses the exact same servers as lsp-mode does.

You’ll need to adapt some hooks and key-bindings, but in terms of capabilities you shouldn’t be losing out.
