devenv.sh - Fast, Declarative, Reproducible, and Composable Developer Environments
Running devenv init generates devenv.nix:
{ pkgs, ... }:
{
# https://devenv.sh/basics/
env.GREET = "devenv";
# https://devenv.sh/packages/
packages = [ pkgs.git ];
enterShell = ''
hello
git --version
'';
# https://devenv.sh/languages/
languages.nix.enable = true;
# https://devenv.sh/scripts/
scripts.hello.exec = "echo hello from $GREET";
# https://devenv.sh/pre-commit-hooks/
pre-commit.hooks.shellcheck.enable = true;
# https://devenv.sh/processes/
# processes.ping.exec = "ping example.com";
}And devenv shell activates the environment.
