When you try to write portable Forth programs it is hard to verify that your program is in deed compatible to a wide variety of Standard Forth systems. It would be ideal if you could test your program against many systems. With Forth systems in docker containers you now can.
This repository provides Dockerfiles for a growing number of popular Forth systems, so it is getting easy to run them for a test drive.
If you are not familiar with Docker, read about it at www.docker.com.
If you want to write Standard Forth programs and contribute them to the community have a look at forth-standard.org and theforth.net
May the Forth be with you.
