flakefast

The goal of flakefast is to provide streamlined access to reproducible and composable development environments for (spatial) data science projects based on Nix flakes. The composition of the environments very much reflects my personal project requirements, so it might not provide the same value to others as it does to me. However, this project also reflects very novice eyes on the Nix ecosystem, so in case you too are learning more about Nix you are invited to have a look around and provide feedback if you wish.

Nix installation

To install Nix:

sh <(curl -L https://nixos.org/nix/install) --no-daemon

Then to enable Flakes for your user:

mkdir -p ~/.config/nix && echo "experimental-features = nix-command flakes" >> ~/.config/nix/nix.conf

Usage

You can investigate what is available via:

nix flake show "github:goergen95/flakefast"

To drop into a shell with a basic installation of R:

nix develop "github:goergen95/flakefast#r-base"

You can also automatically enable a R spatial dev environment directly from GitHub when cding into the project directory via direnv:

echo "use flake \"github:goergen95/flakefast#r-spatial\"" >> .envrc && direnv allow

By adding additional references we can be compose our project environment from multiple ones:

echo "use flake \"github:goergen95/flakefast#py-spatial\"" >> .envrc && direnv allow

Alternativley, templates can be fetched to the project directory to manually customize the project environment:

nix flake init -t "github:goergen95/flakefast#py-spatial"
echo "use flake" >> .envrc && direnv allow
