Picolisp

What a blast from the past!

Picolisp is a lightweight, embeddable scripting language that runs on top of Scheme. Here’s how you can write “Hello World!” in Picolisp:

(println "Hello World!")

Let me break it down for you:

• ( ) – These are the parentheses that group the code together.
• println – This is a built-in function that prints its argument to the console, followed by a newline character (\n).
• "Hello World!" – This is the string literal that gets passed as an argument to println.

To run this code, you’ll need to start a Picolisp interpreter. If you have Picolisp installed on your system, you can do something like this:

$ picolisp
*Welcome to Picolisp!*
?- (println "Hello World!")
Hello World!
?-

Note that ?- is the REPL (Read-Eval-Print) prompt in Picolisp. You can type expressions at this prompt, and they’ll be evaluated immediately.

That’s it!
