GitHub Action to run 32-bit or 64-bit PicoLisp code

This action downloads, compiles, and globally installs PicoLisp. It can be used to run PicoLisp code such as units tests.

Example PicoLisp tests



Optional The version of PicoLisp. Default '20.6'. Accepts 19.12, 19.6, 18.12, 18.6, 17.12, latest, pil21


Optional The architecture of PicoLisp (32 or 64-bit). Default src64. Accepts src, src64

Example usage

- uses: aw/picolisp-action@v2
    version: 18.12
    architecture: src64

- name: Print Hello World with the full PicoLisp version number
  run: pil -'prin "Hello World: "' -version -bye

Example workflow

See the picolisp-json workflow for a more detailed usage example.


This action is written in CoffeeScript, see


  • Unknown values will be replaced with the default value (ex: version: 1.2.3, will become version: 19.12)
  • The PicoLisp environment is extracted to /tmp/picoLisp
  • 32-bit PicoLisp is always compiled
  • 64-bit PicoLisp is bootstrapped from the 32-bit PicoLisp
  • 64-bit PicoLisp will not be compiled if the architecture value is src
  • pil21 technically only works on 64-bit architectures


To build this action:

  • Install NodeJS v12
  • Install the dev dependencies with npm install
  • Generate the dist/index.js with npm run build
