Question: I would like to understand the basics of how to write and execute Lisp program on Linux OS. Can you explain it with a simple example?
Answer: In this article, let us review very quickly how to write a basic Hello World Lisp program and execute Lisp program on Linux or Unix OS.
1. Write a Hello World Lisp Program
Create the helloworld program using the Vim editor as shown below.
$ vim helloworld.lisp ; hello world lisp program. (print "Hello World")
Note: Comment in Lisp starts with ;
2. Make sure Lisp Interpreter is installed on your system
Make sure Lisp interpreter clisp is installed on your system as shown below.
$ which clisp /usr/bin/clisp
Installing clisp interpreter/compiler
If you don’t have Lisp interpreter, install it as shown below.
$ sudo apt-get install clisp
3. Execute the Lisp Program
You can execute using clisp helloworld
$ clisp helloworld "Hello World"
Note: As Lisp program is interpreted, we don’t have the compilation step similar to the C program.
