Clozure CL (CCL) is a Common Lisp implementation. It implements the full ANSI Common Lisp standard with several extensions ( CLOS MOP , threads, CLOS conditions, CLOS streams, ...). It contains a command line development environment, an experimental integrated development environment (IDE) for Mac OS X using the Hemlock editor, and can also be ...
Steel Bank Common Lisp (SBCL) is a free and open-source Common Lisp implementation that features a high-performance native compiler, Unicode support and threading. It is open source software, with a permissive license.
Several Common Lisp implementations (like Clozure CL and SBCL) are implementing eval using their compiler. This way code is compiled, even though it is evaluated using the function eval. The file compiler is invoked using the function compile-file. The generated file with compiled code is called a fasl (from fast load) file.
CL programmers use the language's package facility to declare which functions or data structures are intended for export. Apart from normal ("primary") methods, there also are :before, :after, and :around "auxiliary" methods. The former two are invoked prior to, or after the primary method, in a particular order based on the class hierarchy.
The whitespace-separated notation used in Lisp (and this article) is typical. Line breaks (newline characters) usually qualify as separators. This is a simple context-free grammar for a tiny subset of English written as an S-expression (Gazdar/Melish, Natural Language Processing in Lisp), where S=sentence, NP=Noun Phrase, VP=Verb Phrase, V=Verb:
The Young Learners Tests of English (YLTE) is a set of English language tests for learners in primary and middle grades. The tests are developed by CaMLA, a non-profit collaboration between the University of Michigan and the University of Cambridge. The tests cover all four language skills: listening, reading, writing and speaking.
CMUCL is a free Common Lisp implementation, originally developed at Carnegie Mellon University.. CMUCL runs on most Unix-like platforms, including Linux and BSD; there is an experimental Windows port as well.
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 ...
