Package request: git-annex

[matthiasbeyer]

Would be awesome to have git-annex in termux, so I can sync music and movies from my other devices with it.

[joeyh]

I am the developer of git-annex, and I would also like to see it in termux. Am willing to do work to make it happen.

I do have git-annex building for android. As a haskell program, it needs https://github.com/neurocyte/ghc-android to build.

[joeyh]

@fornwall I see you have a disabled attempt to port ghc at https://github.com/termux/termux-packages/tree/master/disabled-packages/ghc -- I think ghc-android should contain all the patches you need, and I am somewhat familiar with it, if I can help.

That is, ghc-android gets you a ghc that can cross-compile for android. It doesn't get a ghc that runs natively on android, and I think that would be a lot of additional work if it's your goal. That's not needed for porting git-annex though.

[pjones]

I'd love to see this happen! If I can help please let me know.

[jamesd]

So the author of git-annex offers to help make a termux package happen over a year ago and still nothing?

[joeyh]

Well, we're all busy and this is probably somewhat low-priority for all of us and involves a complicated compiler port or cross build.

There has, however, been significant work on ghc for android in the past year, by zw3rk.

• http://hackage.mobilehaskell.org/ has prebuilt cross-compiler for Android, and a growing set of patched libraries.
• https://medium.com/@zw3rk has a lot more

All cross-compiling so far, running ghc on android is not on the map that I know of.

[jamesd]

@joeyh, I'm glad you're still involved. I was worried.

I don't follow Haskell development so I did not know the cross compiler is still in development. With the latest work by zw3rk hopefully we are not too far off from a git-annex package for termux.

[matthiasbeyer]

I'm really looking forward to git-annex on termux for my mobile device, though I have to note that git-annex might be really slow on the devices.

For example, I had the git-annex android app installed some time ago (I own a Oneplus One, which works perfectly well for todays apps still). Cloning my music collection (4347 directories, 52794 files) onto the phone and git annex syncing (not putting the data on my phone, simply syncing the repository) took hours! In the end I aborted it because it took too long.

Still, for smaller repositories/collections, it might be worth it!

[janbuchar]

Do I understand correctly that adding git-annex to Termux would allow starting git-annex when the device boots (using Termux::Boot) without having to open a terminal every time (which is the case with the current git-annex Android app)?

[its-pointless]

Yes

[joeyh]

@jan yes, that would work and would be a nice benefit!

@jan summons me, @joeyh.

[joeyh]

Turns out that the arm tarball from http://git-annex.branchable.com/install/Linux_standalone/ just works in termux. Just untar inside your termux user's home directory, and cd git-annex.linux && ./runshell will add a working git-annex to your path.
