Can't do that for python packages. However, isn't this an application rather than a library?

It's both, because an other tool need to import it to work. What would be suggested to force the dependency version ?

There is none as long as this is in pythonPackages. The suggested way to deal with this is to make an upstream PR that fixes it.

As you see in mautrix/telegram@a258c59, their pinning of telethon is completely useless. Just apply that patch to make it work.

Would you mind adding that tool to this PR or at least giving me a link?

the manual is suggesting that this is the preferred method when a python library is also a application

I'd say it's not actually a library, just a strange requirement of using alembic.
What's your stance @worldofpeace?

I agree that this is an application and belongs in all-packages.nix and alembic just has this requirement.

If you ever need to use it with alembic you can use pkgs.python3.withPackages (ps: [ ps.alembic (ps.toPythonModule pkgs.mautrix-telegram) ]).

So they'd have to do that to setup the bridge.

I think it's only used for updating the database scheme.

I think it should be ok now
