Dev environments for numerous languages based on Nix flakes [maintainer=@lucperkins]

Primary LanguageNix

Nix flake templates for easy dev environments

built with nix

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}

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.

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-utils to all the templates.
