[Feature]: Roll back to previous packages version
Feature Description
As far as I know, Straight.el has command straight-freeze-version
. Is similar feature planned for Elpaca? Ideally, I would love to have ability to roll back packages versions to ones before last upgrade
Confirmation
- [X] The feature I'm proposing does not already exist in Elpaca
Is similar feature planned for Elpaca?
Yes. The elpaca-write-lockfile
and elpaca-load-lockfile
commands are stubbed out in elpaca.el.
I'm still considering some aspects of the design.
I would love to have ability to roll back packages versions to ones before last upgrade
My plan is to make general commands that would make this easy to do. I don't know if I'll provide a "roll back to the the versions just before an update" command specifically, but it will be easy to write one.
It would be nice if these things would be supported:
- A command to write the current hash for a single package
- A key to manually ignore a dirty work tree when processing packages and just write the hash
- A setting to automatically ignore a dirty worktree for certain packages (my main reason for wanting this is that the first Emacs packages I wrote have a lot of unused files I need to clean up but haven't had the time to; I also have todo files in some repos I'd like to clean and add at some point rather than .gitignore)
- An option to to print using lv or something else (so messages/prompts persist even if something else prints to the echo area)
- Some command to validate a configuration/lockfile. Sometimes a recipe (normally a custom one) is no longer valid due to the repo moving, for example. I've even seen a couple cases where a hash was no longer valid due to force pushes to master... It may be overkill/unreasonable for elpaca to do this. You can validate manually by running Emacs with a different home directory, for example.
