What makes a language a lisp?

Lisp (historically LISP) is a family of programming languages with a long history and a distinctive, fully parenthesized prefix notation. Originally specified in 1958, Lisp is the second-oldest high-level programming language. Lisp has changed since its early days, and many dialects have existed over its history.

How is Lisp compiled?

You as a programmer can invoke the compiler, for example in Common Lisp with the functions COMPILE and COMPILE-FILE . Then Lisp code gets compiled. Additionally most Lisp systems with both a compiler and an interpreter allow the execution of interpreted and compiled code to be freely mixed.

What language is Lisp similar to?

Clojure, Haskell, Python, Racket, and Java are the most popular alternatives and competitors to Common Lisp.

What is a lisp file?

Source code file written in Lisp, a programming language that has several different dialects including Common Lisp and Scheme; contains plain text program code that is run with a Lisp interpreter; may be an entire program or a part of a larger Lisp application.

When was lisp programming language created?

LISP, in full list processing, a computer programming language developed about 1960 by John McCarthy at the Massachusetts Institute of Technology (MIT). LISP was founded on the mathematical theory of recursive functions (in which a function appears in its own definition).

What is Lisp in networking?

LISP (Location Identifier Separation Protocol) is a routing and addressing architecture developed by Cisco Systems. Each node on the network has one Endpoint Identifier but may have multiple and variable Routing Locators. The protocol provides a mapping service between them.

When was LISP programming language created?

Why do we need to execute the source code in Lisp?

The source code written in source file is the human readable source for your program. It needs to be “executed”, to turn into machine language so that your CPU can actually execute the program as per instructions given. This Lisp programming language will be used to execute your source code into final executable program.

Is Common Lisp compatible with other programming languages?

The new language, Common Lisp, was somewhat compatible with the dialects it replaced (the book Common Lisp the Language notes the compatibility of various constructs). In 1994, ANSI published the Common Lisp standard, “ANSI X3.226-1994 Information Technology Programming Language Common Lisp”.

What is the difference between Common Lisp and scheme?

Differences between dialects may be quite visible—for instance, Common Lisp uses the keyword defun to name a function, but Scheme uses define. Within a dialect that is standardized, however, conforming implementations support the same core language, but with different extensions and libraries.

What is a valid s expression in Lisp?

The s-expressions are composed of three valid objects, atoms, lists and strings. Any s-expression is a valid program. LISP programs run either on an interpreter or as compiled code. The interpreter checks the source code in a repeated loop, which is also called the read-evaluate-print loop (REPL).
