A lateral lisp occurs when the [s] and [z] sounds are produced with air-flow over the sides of the tongue. It is also called "slushy ess" or a "slushy lisp" in part due to its wet, spitty sound. The symbols for these lateralised sounds in the extensions to the International Phonetic Alphabet for disordered speech are [ʪ] and [ʫ].
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). An S-expression preceded by a single quotation ...
Similar to Kawa's and Clojure's mappings onto the Java virtual machine (JVM), [6] [7] Hy is meant to operate as a transparent Lisp front-end for Python. [8] It allows Python libraries, including the standard library, to be imported and accessed alongside Hy code with a compiling [note 1] step where both languages are converted into Python's AST.
"MLisp" is also another name for Mocklisp, a stripped-down version of Lisp used as an extension language in Gosling Emacs. MLISP is a variant of Lisp with an Algol-like syntax based on M-Expressions, which were the function syntax in the original description of Lisp by John McCarthy. McCarthy's M-expressions were never implemented in an exact ...
In computer programming, CAR (car) / k ɑːr / ⓘ and CDR (cdr) (/ ˈ k ʌ d ər / ⓘ or / ˈ k ʊ d ər / ⓘ) are primitive operations on cons cells (or "non-atomic S-expressions") introduced in the Lisp programming language. A cons cell is composed of two pointers; the car operation extracts the first pointer, and the cdr operation ...
It is an extension of the Logo programming language, a dialect of Lisp. Designed for education, StarLogo can be used by students to model or simulate the behavior of decentralized systems. The first StarLogo ran on a Connection Machine 2 parallel computer. A subsequent version ran on Macintosh computers. It was later renamed MacStarLogo, and ...
Common Lisp is sometimes termed a Lisp-2 and Scheme a Lisp-1, referring to CL's use of separate namespaces for functions and variables. (In fact, CL has many namespaces, such as those for go tags, block names, and loop keywords). There is a long-standing controversy between CL and Scheme advocates over the tradeoffs involved in multiple namespaces.
Dylan was developed at Apple Cambridge, formerly Coral Software, developers of Macintosh Common Lisp. The original language had much in common with Lisp, including its parenthetical S-expression syntax. For a time, it was developed with the intent of being the primary language of the Apple Newton. When that project was ordered into production ...
