This is a docker image to run the Lem editor and start coding in Common Lisp.
Run the editor:
docker run --rm -ti -v `pwd`:/app 40ants/lem
Then hit the M-x (on OSX Meta key usually "option" or "command" key, depending on your terminal's settings).
And enter start-lisp-repl
command. It will open the REPL with Common Lisp.
To edit real files, you will need to pass the directory into the docker container by adding such option -v `pwd`:/app
to the docker run
command.
