test everything

just is a handy way to save and run project-specific commands.

Commands are stored in a file called justfile or Justfile with syntax inspired by make:

build:
    cc *.c -o main

# test everything
test-all: build
    ./test --all

# run a specific test
test TEST: build
    ./test --test {{TEST}}

just produces detailed error messages and avoids make's idiosyncrasies, so debugging a justfile is easier and less surprising than debugging a makefile.

It works on all operating systems supported by Rust.
