simple janet quickbin example: build with `jpm quickbin main.janet fmt`

main.janet

(import spork/fmt)

(defn main [_ filename]
  (fmt/format-file filename))

project.janet

(declare-project
  :name "fmt"
  :description "formats janet code"
  :dependencies ["https://github.com/janet-lang/spork"])

(declare-executable
  :name "fmt"
  :entry "main.janet")

If you have no dependencies or the the dependencies are already in your system, then you can also use jpm quickbin to make an executable without a project.janet

> jpm quickbin main.janet fmt
> ./fmt main.janet
