persp-mode.el VS persp-projectile

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?

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).

Aye. I often have two interdependent projects I work on simultaneously, and I use a lot of persp-projectile (https://github.com/bbatsov/persp-projectile). I would love to try project.el but sadly it seems like it doesn't integrate with perspective.el yet.

I also use purely emacs for "commercial programming" (as you refer to it) and for managing multiple projects I use projectile + perspective + persp-projectile.

I had my own rolled version of this in my config until recently when I swapped to perspective and perspective-projectile.
