Nix flake templates for easy dev environments

---

NOTICE for recent changes

Several language toolchains were removed due to low popularity.

Some other toolchains are migrating to better implementation from other projects.

Sorry for any inconvenience :(

---

To initialize (where ${ENV} is listed in the table below):

nix flake init -t github:definfo/dev-templates#${ENV}

How to use the templates

Once your preferred template has been initialized, you can use the provided shell in two ways:

1. If you have [nix-direnv][nix-direnv] installed, you can initialize the environment by running direnv allow.
2. If you don't have nix-direnv installed, you can run nix develop to open up the Nix-defined shell.

Code organization

All of the templates have only the root flake as a flake input. That root flake provides a common revision of [Nixpkgs] and [flake-parts][flake-parts] to all the templates.
