add flake.nix

[RCasatta]

This allow to build the project executables with nix.

nix build . # builds teosd and teos-cli

nix build .#plugin # builds watchtower-client

UPDATE: worth mentioning experimental features nix-command and flake are required, either enabled via the command or globally

Thanks!

Could this tolerate being in a sub/nested directory (e.g. dist).

There are probably other package managers could build/use teos in a certain way. I imagine lots of these files in the projects root directory gonna be messy in the future.

Maybe this could fit here: https://github.com/talaia-labs/rust-teos/tree/master/contrib

Putting it in a sub-directory would prevent most of the usefulness. From the docs:

A flake refers to a file-system tree whose root directory contains the Nix file specification called flake.nix.

The standard position allows to run the executable also with this syntax:

nix run github:talaia-labs/rust-teos # this is for master, it's possible to use a specific branch or commit hash

fixed

I'm curious about what the issue with this is. I'm not familiar with Nix so just wondering

[RCasatta]

The issue is that changing the released version in Cargo.toml require changing the version here, while instead the value should be read from the Cargo.toml thus not requiring to keep this file in sync.

@seberm you may be interested in this, given fort-nix/nix-bitcoin#543

Would you mind giving it a try if so?

Works for me, but I don't know if this flake.nix is idiomatic. There are a bunch of trailing whitespaces and a tab.

Is this fixable by running it though nixfmt?
