I think 'jjhub' is a decent immediate first approximation, and is often how I've started out talking about it with people. At the same time, we have to offer real value here, as you can already use jj with github (and I have for a long time now), so there's more to it than that. But yes :)

If you're starting over with a new backing store using jj's pluggable backends, can you give us a native lazily-materialized store for megarepos? It's a tragedy that the open-source world has no answer to piper.

What I would love:

- Everything locally stored in the repo: PRs, comments, issues, discussions, boards, ... - CLI first - Offline first (+ syncing) - A website for hosting/presentation

Noted :) In another comment I linked to beads, which is a cool project to keep your issue tracker in your repo, but that's just a personal thing, no comment on what the company plans to do (or not) in this area.

I use command-line tooling much more than IDEs (e.g. VS Code), so the `gh` command-line tool (https://cli.github.com) for doing most of the usual hub-oriented workflow (PR authoring, viewing issues, status updates, etc) really helps a lot - I don't have to constantly <cmd>+<tab> to my browser, and point-click-point-click through web pages so much. It would be fantastic if ersc or any other jj-centered code-sharing hub had similar tooling early on.

I'm a big CLI for VCS person, so yeah, I use those tools too :)

So you want Fossil?

When I tried Fossil it had things weirdly separated.

I was expecting when I make a commit, I would have the facility to specify what issues it addressed and it would close them for me automatically. It seemed there is so much opportunity there to "close the loop" when the issue tracker, etc and integrated in your VCS, but it wasn't taken.

except fossil decided to never allow changing history, vs jj which makes history rewriting so much easier

That's my favourite thing about fossil though. History is what it is, not simplified to look "clean" (i.e. hide what actually happened and when) and you get a lot fewer footguns to ruin everything by accidentally rebasing things to the wrong place without noticing.

I would love having some first class support for monorepos at bigger organizations (ex: silos, vfs, etc).

No promises but noted for sure…

> we have to offer real value here

If I may make a suggestion here: Allowing PRs to be stacked, i.e. allowing commits to be reviewed individually, like in Sapling, would be FANTASTIC.

EDIT: See also the link in this comment: https://news.ycombinator.com/item?id=45675335

This is something that I am comfortable saying is absolutely going to be the case.

That's great to hear! Looking forward to ERSC!

There’s this as well: https://blog.tangled.org/stacking

I personally find this to be more interesting simply because it has the social inertia of Bluesky behind it. Software has centralized on GitHub because it is discoverable there. Software on Tangled is discoverable through Bluesky, and the stacking support to make jj nice to use with it is just an added bonus.

Gerrit also maps really nicely to jj concepts, and there is an accepted RfC to add support for Jujutsu change IDs to Gerrit.

jjhub sounds rather frabjous

This is a great thing and I'm hoping for its success. It's about time we have a real alternative to Github.

What makes GitLab not a real alternative?

Another reason to leave GitHub and their weekly downtime!

Can't wait for them to have their BigCo exit and get rich like the GitHub guys /s
