Lisp, Scheme, Racket (can be nested in all three). #= ~ =# Julia ... Scheme and Racket. The next complete syntactic component (s-expression) can be commented out with #;.
The Racket language is a modern dialect of Lisp and a descendant of Scheme. It is designed as a platform for programming language design and implementation. [9] In addition to the core Racket language, Racket is also used to refer to the family of programming languages [10] and set of tools supporting development on and with Racket. [11]
The Racket language is a modern dialect of Lisp and a descendant of Scheme. It is designed as a platform for programming language design and implementation. [9] In addition to the core Racket language, Racket is also used to refer to the family of programming languages [10] and set of tools supporting development on and with Racket. [11]
Like all implementations in the Scheme family, Racket implements full tail call elimination. Racket takes this further: the language is made fully safe-for-space, via live variable analysis. This complements the precise garbage collector and in some cases, like in the implementation of Lazy Racket, the two features are crucial for proper execution.
Mostly based on Scheme and Common Lisp, was designed as system and application programming language by Apple; first used to write an operating system and applications for internal prototypes of the later released Apple Newton computer; first official version of Apple Dylan also had s-expression based syntax; Apple collaborated with partners to ...
Rich Hickey, creator of Clojure. Rich Hickey is the creator of the Clojure language. [19] Before Clojure, he developed dotLisp, a similar project based on the .NET platform, [27] and three earlier attempts to provide interoperability between Lisp and Java: a Java foreign language interface for Common Lisp (jfli), [28] A Foreign Object Interface for Lisp (FOIL), [29] and a Lisp-friendly ...
Lisp programs are valid S-expressions, but not all S-expressions are valid Lisp programs. (1.0 + 3.1) is a valid S-expression, but not a valid Lisp program, since Lisp uses prefix notation and a floating point number (here 1.0) is not valid as an operation (the first element of the expression).
Today, the best-known general-purpose Lisp dialects are Common Lisp, Scheme, Racket, and Clojure. [6] [7] [8] Lisp was originally created as a practical mathematical notation for computer programs, influenced by (though not originally derived from) [9] the notation of Alonzo Church's lambda calculus.
