hs-logo is an interpreter for the Logo Programming Language, written in Haskell. It is specialised for Turtle graphics, and is not intended to be a full-fledged Logo interpreter.
Read the installation guide , and then browse the examples to get started. You can execute your logo files to generate an image like below. A more detailed user guide will be added soon.
% hs-logo example.logo -o example.svgThe interpreter is still a work in progress, and more primitives will be added soon. I also plan to write user guide sometime before the next release. You can find the sources at the hs-logo project on github.
