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 ...
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.
[3] [4] The main point of divergence at the time was a clean bootstrapping procedure: CMUCL requires an already compiled executable binary of itself to compile the CMUCL source code, whereas SBCL supported bootstrapping from theoretically any ANSI-compliant Common Lisp implementation. SBCL became a SourceForge project in September 2000. [3]
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.
Evaluation does not have to mean interpretation; some Lisp systems compile every expression to native machine code. It is simple, however, to describe evaluation as interpretation: To evaluate a list whose car names a function, eval first evaluates each of the arguments given in its cdr, then applies the function to the arguments.
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 ...
Gambit, also called Gambit-C, is a programming language, a variant of the language family Lisp, and its variants named Scheme.The Gambit implementation consists of a Scheme interpreter, and a compiler which compiles Scheme into the language C, which makes it cross-platform software.
CLISP is extremely portable, running on almost all Unix-based operating systems as well as on Microsoft Windows.Although interpreting bytecode is usually slower than running compiled native binaries, this is not always a major issue (especially in applications like Web development where I/O is the bottleneck).
