This section provides an overview of what lisp is, and why a developer might want to use it.
It should also mention any large subjects within lisp, and link out to the related topics. Since the Documentation for lisp is new, you may need to create initial versions of those related topics.
Probably the two most popular free implementations of Common Lisp are Clozure Common Lisp (CCL) and Steel Bank Common Lisp (SBCL). They are both available for a variety of platforms including Linux on x86-64 and Linux on ARM.
Besides the compiler and basic Read-Eval-Print Loop (REPL), you may want some sort of development environment. One popular setup is to use Emacs to edit text interactively. The Superior Lisp Interaction Mode for Emacs (SLIME) allows Emacs to connect to a Lisp implementation and evaluate code interactively, from the editable text file and from a REPL within the Emacs editor:
Invented by John McCarthy around 1958, Lisp (List Processor) has continued to grow into an entire family of languages.
Since StackOverflow is more about practical programming problems, typically problems will involve actual Lisp dialects or derived languages and their implementations. Problems that are generally Lisp-related may be tagged with lisp. There are many dialects and implementations, but not all are significant for StackOverflow.
Important dialects and related languages are:
