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]
Common Lisp implementations may use any mix of native code compilation, byte code compilation or interpretation. Common Lisp has been designed to support incremental compilers, file compilers and block compilers. Standard declarations to optimize compilation (such as function inlining or type specialization) are proposed in the language ...
Lisp dialect first standardized in a book, "Common Lisp the Language", by Guy L. Steele, [12] developed as a standardized and improved successor of Maclisp; statically and dynamically scoped; strongly-typed, allows (optional) type declarations; [13] separate namespaces for functions versus data variables, a trait often named Lisp-2; object ...
Scribble, Racket's documentation system, comes in the form of a number of languages that are used to write prose. It is used for Racket's documentation, as well as writing books and articles. Actually, rather than a single "scribble" language, it is a family of (very similar) dialects, each for a different purpose.
In the Common Lisp dialect, destructive functions are commonplace; the equivalent of set-car! is named rplaca for "replace car". This function is rarely seen, however, as Common Lisp includes a special facility, setf, to make it easier to define and use destructive functions. A frequent style in Common Lisp is to write code functionally ...
The familiar (but puzzling to newcomers) names CAR and CDR used in Lisp to describe the head element of a list and its tail, evolved from two IBM 704 assembly language commands: Contents of Address Register and Contents of Decrement Register, each of which returned the contents of a 15-bit register corresponding to segments of a 36-bit IBM 704 ...
