Questions tagged [interpreter]

An interpreter is a program that executes, i.e. performs, instructions written in a programming language. The tag [interpreter] should be applied to questions concerning the programming of interpreters or for questions about the detailed inner workings of interpreters. Use [interpreter-pattern] (possibly with this tag) for questions about the Gang of Four design pattern.

An interpreter is a program that executes, i.e. performs, instructions written in a programming language.

An interpreter may be a program that either

  1. executes the source code directly
  2. translates source code into some efficient intermediate representation (code) and immediately executes this
  3. explicitly executes stored precompiled code1 made by a compiler which is part of the interpreter system

How to invoke an interactive elisp interpreter in Emacs?
