To compile by yourself download and extract Urn:

https://urn-lang.com/

i suggest to make an alias, something like this:

alias urn "lua urn-master/bin/urn.lua"

then type:

urn -o led.lua led.lisp

or:

urn -o led.src.lua led.lisp
luac -s -o led.lua led.src.lua

On UNIX systems with XTerm please install XSel and rlwrap:

alias led='rlwrap -c /path/to/lua /path/to/led.lua'

inside ~/.Xresources insert something like this:

XTerm*VT100.Translations:       #override\n\
 Super <KeyPress> v: insert-selection(PRIMARY)\n\
 Super <KeyPress> c: copy-selection(PRIMARY)\n

when select to edit a line paste it on prompt from clipboard;
works also on AmigaOS, MorphOS and AROS.
