My Lisp is a complete and universal Lisp environment running directly on the iPhone, iPad, and Mac. This interpreter is true to the original John McCarthy Lisp implementation with the fundamental 7 operators quote, atom, eq, car, cdr, cons, cond, along with lambda and label. My Lisp also contains core and mathematical operators borrowed from other Lisp dialects (Le Lisp, Lisp 1.5, MacLisp, Common Lisp and Scheme to name a few) to make it easy to learn, program, and most importantly, enjoy Lisp. It also features built-in functions for advanced mathematics, including complex numbers and numerical analysis (roots and zeros finder, integral approximation). The complete description of the fundamental, core, and built-in functions is available using a set of library functions completely written in My Lisp.

My Lisp offers an interpreter and an editor, all working on the iPhone, iPad, and Mac, and most importantly, without requiring any server connection, that is, the interpreter is executing locally on the iPhone, iPad or Mac My Lisp is installed on.

Library and example files contain the source code of classical functions and problems solved by My Lisp and may be used as reference to learn Lisp and develop other programs. They include classical puzzles (hanoi and n-queens), basic mathematical functions (gcd, lcm, factorial, fibonacci, prime?), and the historical apply, mapcar and maplist functions. The Lambda Calculus example file contains various functions related to Lambda Calculus and Combinators, with alpha-conversion, beta-reduction, de Bruijn notations, etc. As a special note, the example file Symbolic Derivation contains a complete yet extensible symbolic derivation module allowing to compute the formal derivation of virtually any symbolic function expressed as a Lisp expression.

A user manual and a reference manual are available from within the application but also on My Lisp web site (https://lisp.lsrodier.net) and in Apple Books. The complete source code of the library and example files is part of My Lisp.

Last but not least, this overview couldn’t end without a sample definition of the notorious REPL function:
(define (REPL eval_me) (REPL (println (eval (read)))))

Great app. Missing parentheses matching.A well implemented app with files app integration and a syntax highlighting editor. If only the app had parentheses matching, this app would rock as hell. Love it, none the less..KaysovVersion: 1.69

AmazingI’m in love with this app. The experience of reading the lambda white paper and being able to work through it myself ON MY iPHONE is phenomenal. To any philosophers-in-training out there who are studying “quantitative reasoning,” buy this app now and you can stop asking “what will I use symbolic logic for.” It’s like giving Plato a graphing calculator. Plato’s updated slogan may as well be “let no one know enter philosophy who does not know Lisp.”.OneTrackSystemVersion: 1.64

Very nice iOS implementationNice lisp interpreter I’m on iOS. It’s fast and extensible. Includes a number of examples. Nice editor and other tools included. Can’t beat the price..W_HVersion: 1.87

Get it, use it, you won’t regret itHas parens matching now. Keeps getting better and better..DarkRadonVersion: 1.77

Simply AwesomeThis app is awesome. It’s simple, minimal and easy to use if you know the lisp language. I wish it had graphics capability for games, artwork and charting, sound/ audio capabilities and some interactive capability for screen touch and screen orientation like Pythonista and Codea provide. And access to system functions like the date and time and filesystem. I wish it had a prolog interpreter with lisp source available and an external repository of lisp code like rosettacode.org.JedishrfuVersion: 1.64

Great for learning LISPI wanted to have on device LISP interpreter to do examples as I go along Peter Norvig AI Paradigm book. This app makes LISP just a swipe away..Alex PopovVersion: 1.75
