plugins/luasnip: backport SnipMate loader

[cezdro]

I created this commit some time ago (under @nawordar account), but I drive NixOS stable and the main branch of NixVim is not compatible anymore (missing cmp-ai package).

Is this purely additions with no changes to existing options? We don't normally backport, but I'm fine with merging the occasional backport if is additive only and has no breaking changes.

I'm not sure what's going on with the CI failure, it may be unrelated.

I'd like to point out though, it is possible to use the main nixvim branch by doing a standalone build and then including the package in your system packages. But this is a slightly different workflow to using the nixos/hm/darwin modules.

In the future (#1784), it should be possible to tell nixvim to use a different pkgs to your system modules. That would also allow you to have a mixed build where you use 24.05 on the host and unstable in nixvim.

I'm using NixVim as a home-manager module and home-manager as a NixOS module. I tried adding inputs.nixvim.inputs.nixpkgs.follows = "nixpkgs-unstable", but it didn't change anything. Do I understand correctly that home-manager still passes the 24.05 branch of nixpkgs?

Yes, this commit only adds an option and does some clean up as discussed in #1643.

Unfortunately, I don't have a Mac, so I can't test what is going on with the test

Yes, currently the only way to use a nixvim from unstable on a system running a stable channel is to use nixvim's standalone build method, linked above.

Correct, that's what #1784 is about; adding a way to configure programs.nixvim.nixpkgs.pkgs.

Yes, this commit only adds an option and does some clean up as discussed in #1643.

Thanks for clarifying!

Yes, Darwin can be a bit of a pain; some tests just don't run well on it.
