I hadn't heard of Pijul. My first search took me to https://github.com/8l/pijul which hasn't been updated in 11 years, but it turns out that's misleading and the official repo at https://nest.pijul.com/pijul/pijul had a commit last month.

... and of course it is, because Pijul uses Pijul for development, not Git and GitHub!

> I hadn't heard of Pijul

I'm surprised! Pijul has been discussed here on HN many, many times. My impression is that many people here were hoping that Pijul might eventually become a serious Git contender but these days people seem to be more excited about Jujutsu, likely because migration is much easier.

Looks like it makes the homepage only once or twice a year (using points>50 as a proxy for that), had more buzz around five years ago: https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...

I too am here all the time and have never heard of it. But it looks interesting.

The canonical website is https://pijul.org. The homepage has a link to the pijul source repository.

They should mirror on GitHub for marketing purposes

[nicoty]

How would they do that if they don't use git for version control? Does GitHub allow other forms of version control other than git?

[simonw]

SQLite does it despite using Fossil - their mirror is at https://github.com/sqlite/sqlite

Git is so established now that it's sensible for alternative VCS to have a mode where they can imitate the Git protocol - or seven without that you can still checkout the latest version of your repo and git push that on a periodic basis.

Git is not a protocol, it is a data format. That only makes sense when your VCS system is similar enough to git to easily allow converting between the two representations.

[simonw]

I mean things like git-svn, hg-git, git-p4, git-remote-fossil, git-tfs, jj.

[verdverm]

Similarly, CUE uses Gerrit and has two way sync. If you are building a VCS today, git interop is a must.

[adastra22]

What if the whole point of your VCS is that it its core data structure is nothing like git's at all?

pijul clone https://nest.pijul.org/pijul/pijul

pijul log --hash-only > all_changes.txt

pijul unrecord --all

git init

``` for HASH in $(cat all_changes.txt); do pijul apply "$HASH" pijul reset # sync working copy to channel state git add -A git commit -m "pijul change: $HASH" done ```

git remote add origin [e-mail]:you/pijul-mirror.git git push -u origin main
