Scripts

Scripts are your friends!

devenv.nix
{pkgs,...}:{
packages=[pkgs.curl pkgs.jq];
scripts.silly-example.exec='curl "https://httpbin.org/get?$1" | jq '.args'';
}
            

Aliases & args

Here's an example that shows how to define an alias & forward arguments:

scripts.foo.exec = ''npx @foo/cli "$@";'';
            

Pinning packages inside scripts

Sometimes we don't want to expose the tools to the shell but still make sure they are pinned in a script:

devenv.nix
{pkgs,...}:{
scripts.silly-example.exec='${pkgs.curl}/bin/curl "https://httpbin.org/get?$1" |${pkgs.jq}/bin/jq '.args'';
}
            

Using your favourite language

Scripts can also execute using a package and have a description, which can be useful in yourenterShell.

devenv.nix
{pkgs,config,lib,...}:{
scripts.python-hello={exec='print("Hello, world!")';package=config.languages.python.package;description="hello world in Python";};
scripts.nushell-greet={exec='def greet [name] {["hello" $name]}greet "world"'';package=pkgs.nushell;binary="nu";description="Greet in Nu Shell";};
enterShell='echoecho 🦾 Helper scripts you can run to make your development richer:echo 🦾${pkgs.gnused}/bin/sed -e 's| |••|g' -e 's|=| |' <
