crate2nix VS himalaya

I'll use nixpkgs' buildRustPackage. There's a few other tools, my favorite being crate2nix, but we'll leave that to a future tutorial.

If you want to iterate with nix instead of cargo, crate2nix and cargo2nix provides more caching and more fine control over your dependencies. I haven't used these two so you would have to decide for yourself. You may also want to try out nocargo for something more experimental.

I'm yet to try it out, but from the blog post, the README and the source it appears that Crane builds all dependencies in one derivation (separately from the main crate). This means that if a dependency gets added, removed or changed, all dependencies of a crate will be rebuilt. This is in contrast with https://github.com/kolloch/crate2nix, which does build every dependency in a separate package, thus you don't need to rebuild other dependencies if you only change a small part of the tree.

Yes, you will have to package it if it's not already in nixpkgs.

The good news is once you learn how, it's basically trivial with crate2nix[0], which can autogenerate nix derivations from rust crates

From my quick reading of cargo2nix's webpage yes. https://github.com/kolloch/crate2nix has a workspaces section.

As for your two applications, they're both written in Rust, and I like https://github.com/kolloch/crate2nix as a way to package Rust crates with Nix. BTW, wezterm is already in nixpkgs!

I like the way crate2nix works. I have made a flake template for it here. Sometimes it requires a couple of overrides to fix some misbehaving crates (see https://github.com/balsoft/simple-osd-daemons/blob/master/flake.nix#L29 for an example of such overrides), but otherwise it's fantastic. It doesn't require any hash nonsense, it downloads and builds all the crates separately (unlike naersk or other solutions) so you get all the benefits of Nix (reproducibility and proper caching).

Before you going deeper, take a look at himalaya if it fit to your needs.

https://github.com/soywod/himalaya this one also is a thing, has a vim plugin too

Take a look at Himalaya: https://github.com/soywod/himalaya

You can use himalaya for that

We live in a time of a Renaissance of terminal tools. I recently discovered Himalaya[1], a command line tool for email, and I really like it. I'm also interested in exploring a new tool for calendar called qcal[2]. I'm kicking around writing a chat client for GroupMe for the terminal right now. That way I could finally ditch pidgin.

Like the OP, I spend all day in tmux these days, which is in many ways the most superior UI[3]. As a bonus, CLI tools are often cross-platform and very easy to write.
