Nix flake templates for easy dev environments

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

nix flake init --template github:the-nix-way/dev-templates#${ENV}

Here's an example (for the rust template):

# Initialize in the current project
nix flake init --template github:the-nix-way/dev-templates#rust

# Create a new project
nix flake new --template github:the-nix-way/dev-templates#rust ${NEW_PROJECT_DIRECTORY}

Note

: All templates are pinned to the 22.11 release of Nixpkgs.

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 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.
