`just`

There are no Nix options for just, but there is a nixpkg.

Create a Justfile like:

justfile

# run the thing
run:
    npx astro dev

# run the tests
test:
    npx jest

List out your commands like:

shell

> just -l
Available recipes:
    run  # run the thing
    test # run the tests

Define arguments in your recipes like:

justfile

# run the thing
run port:
   npx astro dev --port {{port}} --open

And call them like:

shell

just run 8080

Define variables like:

justfile

platform := `uname`
nproc := `nproc`

version := "0.1.7"

Use them the same.

Get environment variables like:

justfile

say_hello:
    echo "Well hi there, ${USER}!"

Export environment variables into the recipes like:

justfile

export TZ = "Australia/Melbourne"

clock:
    node -pe "new Date().toString()"

shell

# you too, can be australian
> just clock
Fri Sep 13 2024 21:19:11 GMT+1000 (Australian Eastern Standard Time)

Use your favourite language like:

justfile

bam:
    #!/usr/bin/env node
    console.log("Finally, console.log in another place 🤡")

just also has a chooser:

shell

just --choose

You can make the chooser your default recipe:

shell

default:
    @just --choose

(It's also just... their README...)
