Or use maven CLI to fetch the artifacts from maven central:

mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:get -Dartifact=io.opsit:opsit-explang-core:0.0.8:jar:runnable   -Dtransitive=false -Ddest=opsit-explang-core-0.0.8-runnable.jar

Using Explang Runnable Jar

Using REPL

Explang-core contains built-in REPL. Run it in a terminal emulator or in Windows console:

$ java -jar opsit-explang-core-0.0.8-runnable.jar 
Welcome to the EXPLANG REPL!
Active parser is LispParser
Loaded packages are: [base.math, base.text, io, base.bindings, ffi, base.funcs, loops, threads, base.version, base.coercion, base.logic, base.lang, base.arithmetics, base.seq, base.control, base.regex, dwim, base.docs, base.beans, base.types]
Please type an EXPLANG expression 
[0]> (print "hello, world!\n")
hello world

=> hello world

[1]>

This built-in REPL implementation does not support editing of and command history, so one is may want to it with some kind of wrapper such as rlwrap, VS Code repeater REPL extension, Emacs inferior lisp mode.

There is a REPL implementation with editing and history support in a separate project Explang JLine REPL.

To exit press ^D (^Z on Windows console) on a new line.

Executing Explang Scripts

$ java -jar opsit-explang-core-0.0.8-runnable.jar ./examples/hello.l
