CLPython is an implementation of the Python programming language written in Common Lisp. This project allow to call Lisp functions from Python and Python functions from Lisp. Licensed under LGPL. CLPython was started in 2006, but as of 2013, it was not actively developed and the mailing list was closed. [1]
Lisp source code is made of lists. Thus, Lisp programs can manipulate source code as a data structure, giving rise to the macro systems that allow programmers to create new syntax or new domain-specific languages embedded in Lisp. The interchangeability of code and data gives Lisp its instantly recognizable syntax. All program code is
Lisp was the first language where the structure of program code is represented faithfully and directly in a standard data structure—a quality much later dubbed "homoiconicity". Thus, Lisp functions can be manipulated, altered or even created within a Lisp program without lower-level manipulations.
A Lisp compiler generates bytecode or machine code from Lisp source code. Common Lisp allows both individual Lisp functions to be compiled in memory and the compilation of whole files to externally stored compiled code (fasl files). Several implementations of earlier Lisp dialects provided both an interpreter and a compiler.
The association list provides a simple way of implementing this data type. To test whether a key is associated with a value in a given association list, search the list starting at its first node and continuing either until a node containing the key has been found or until the search reaches the end of the list (in which case the key is not ...
In Python, it is the <__module__.class instance> notation, and in Common Lisp, the #<whatever> form. The REPL of CLIM, SLIME, and the Symbolics Lisp Machine can also read back unreadable objects. They record for each output which object was printed. Later when the code is read back, the object will be retrieved from the printed output.
AutoLISP, a programming and scripting language for AutoCAD, is based on a very old version of XLISP. XLISP-PLUS is a derivative of XLISP 2.0 that continues to add Common Lisp features. Winterp is a derivative of XLISP-PLUS. XLISP-STAT is an implementation of Lisp-Stat, an environment for dynamic graphics and statistics with objects.
Practical Common Lisp is an introductory book on the programming language Common Lisp by Peter Seibel. [1] It features a fairly complete introduction to the language interspersed with practical example chapters, which show developing various pieces of software [2] [3] such as a unit testing framework, a library for parsing ID3 tags, a spam filter, and a SHOUTcast server.
