projectile VS persp-mode.el

Could you explain more about this setup? I'm not familiar with "projectile". Is this https://github.com/bbatsov/projectile the same thing you're referring to?

Sounds interesting. What I've done recently is open my vim in the folder that contains all the organization's repos (the ones I've cloned) and just run ripgrep inside vim to find examples or references to whatever I've seeking. Seems performant enough even without doing anything except letting ripgrep ignore git-ignored stuff (default behavior of ripgrep).

Sure. It sounds like it's working well enough. Here's a Github issue that may be of interest to you. Apparently you can get this behavior if there's a project marker file at a higher level.

With projectile you can define custom "run", "compile", "test" commands per project. Also there are pre-defined commands for many known project types.

Thanks for your detailed explanation, but no that is no that is not the question. This is projectile: https://github.com/bbatsov/projectile

I am currently trying with perspective rather than persp-mode, as it segregates the buffer list as I like (#1 above). I've got projectile with persp-projectile, and that seems to give me what I need for project navigation (#2 probably, still not 100%). I get some help in my mode line for project focus (#3, partially).

I'm just switching to emacs (a noob). As far as I understood, doom uses " persp-mode.el " package instead of emacs built-in tab-mode. In order to reorder the tabs, tab-mode has tab-move and vim has tabmove. How can we do the same for doom?

I assume that it's the workspaces module in Doom Emacs which is powered by persp-mode.el.

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’ll also add that along with project.el/projectile persp-mode can be configured to work as you desire. persp-mode allows you to create different perspectives (or groups) of buffers. I usually have a few different perspectives and a project open in each of them.

You could try perspective or persp-mode

Doom achieves this via persp-mode.

The workspaces module in Doom uses persp-mode.

Built-in elisp -- are there libraries in emacs that could be extended? Here are two ideas: project.el is a great start but is lacking in some ways, especially as compared to an external library like projectile.el. Could you write up something to extend project.el's functionality by comparison? Similarly, tab-bar-mode is great, but one thing it is missing is a way to group buffers by tab, as something like persp-mode does. Could you write something that would extend this functionality to cover that case?
