There are several new dialects of Lisp: Arc, Hy, Nu, Liskell, and LFE (Lisp Flavored Erlang). The parser for Julia is implemented in Femtolisp, a dialect of Scheme (Julia is inspired by Scheme, which in turn is a Lisp dialect). In October 2019, Paul Graham released a specification for Bel, "a new dialect of Lisp."
Common Lisp: 1984: 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 ...
As in almost all other Lisp dialects, lists in Common Lisp are composed of conses, sometimes called cons cells or pairs. A cons is a data structure with two slots, called its car and cdr. A list is a linked chain of conses or the empty list. Each cons's car refers to a member of the list (possibly another list).
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]
Lisp Flavored Erlang (LFE) is a functional, concurrent, garbage collected, general-purpose programming language and Lisp dialect built on Core Erlang and the Erlang virtual machine . LFE builds on Erlang to provide a Lisp syntax for writing distributed, fault-tolerant , soft real-time , non-stop applications.
In 2001, Paul Graham announced that he was working on a new dialect of Lisp named Arc.Over the years since, he has written several essays describing features or goals of the language, and some internal projects at Graham's startup business incubator named Y Combinator have been written in Arc, most notably the Hacker News web forum and news aggregator program.
Scheme is a dialect of the Lisp family of programming languages.Scheme was created during the 1970s at the MIT Computer Science and Artificial Intelligence Laboratory (MIT CSAIL) and released by its developers, Guy L. Steele and Gerald Jay Sussman, via a series of memos now known as the Lambda Papers.
The language was conceived to teach concepts of programming related to Lisp and only later to enable what Papert called "body-syntonic reasoning", where students could understand, predict, and reason about the turtle's motion by imagining what they would do if they were the turtle. There are substantial differences among the many dialects of ...
