elpa-mirror VS straight.el

(and thinking about strategies around this. there is elpa-mirror, which allows for the creation of local Emacs package repos, but I wonder about a good way of automating periodic updates to the mirrored repo without necessarily updating the packages of the local running Emacs.)

You could use https://github.com/redguardtoo/elpa-mirror

You can also create your own local repo from installed packages, see https://github.com/redguardtoo/elpa-mirror

You could use https://github.com/redguardtoo/elpa-mirror before migrating your setup. The elpa-mirror create a local repository from you installed packages. Then you can use the local repository to replace remote repository during migration. As its README said, "15 seconds to install 115 packages".

Thanks for that. I downloaded a .zip from this resource which is maintained with elpa-mirror. I unpacked the .zip on the walled-off system, and I now have an up-to-date package archive online after modifying my ~/.emacs.d/init.el.

Besides, I use https://github.com/redguardtoo/elpa-mirror to create my local package repository in case GNU elpa or melpa is shutdown.

Very dated and next to useless on large complex CPP codebases. Use a language server. I recommend the straight package manager. https://github.com/radian-software/straight.el

Have you tried using straight.el or the heir-apparent Elpaca? These package managers will check out the git repo of said packages, and you can easily fork them with magit and forge. That's that I do to contribute to packages.

Thank you for your time addressing all those issues and sorry if questions were misinformed - I found your advices invaluable to understand design goals of package managers in emacs.

I used straight.el, now I use Elpaca.

Doom Emacs is not a package manager. It has a package manager, which is based on Straight.el.

I have been crafting my emacs config for about 10 years. I started with vanilla and intentionally stayed away from frameworks. About two years ago I declared config bankruptcy and went down for a rewrite using use-package and straight.

First install straight.el (https://github.com/radian-software/straight.el)

If you use straight and override package, you'll get a lot of your desired functionality for free. Straight's docs are excellent. I started banging away on my own setup from scratch, and while not perfect, it does what I want and the total startup time is about 1.5 seconds without doing anything to try to optimize it. If you want to see it, check it out here. Like I said, there is lots of room for improvement, but it does work for me.
