Nix flake templates for easy dev environments

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

nix flake init --template "https://flakehub.com/f/the-nix-way/dev-templates/*#${ENV}"

You can also use the shorter GitHub form:

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

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

# Initialize in the current project
nix flake init --template "https://flakehub.com/f/the-nix-way/dev-templates/*#rust"

# or with the short GitHub form
nix flake init -t github:the-nix-way/dev-templates#rust

# Create a new project
nix flake new --template "https://flakehub.com/f/the-nix-way/dev-templates/*#rust" ${NEW_PROJECT_DIRECTORY}

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.
