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.
Format is a function in Common Lisp that can produce formatted text using a format string similar to the print format string.It provides more functionality than print, allowing the user to output numbers in various formats (including, for instance: hex, binary, octal, roman numerals, and English), apply certain format specifiers only under certain conditions, iterate over data structures ...
In the Common Lisp dialect, destructive functions are commonplace; the equivalent of set-car! is named rplaca for "replace car". This function is rarely seen, however, as Common Lisp includes a special facility, setf, to make it easier to define and use destructive functions. A frequent style in Common Lisp is to write code functionally ...
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 Lisp-2; object ...
Embeddable Common Lisp (ECL) is a small implementation of the ANSI Common Lisp programming language that can be used stand-alone or embedded in extant applications written in C. It creates OS-native executables and libraries (i.e. Executable and Linkable Format (ELF) files on unix) from Common Lisp code, and runs on most platforms that support ...
The code examples were highlighted as being the strength of the book, being small enough to understand, but large enough to illustrate and motivate important techniques in symbolic programming. [ 8 ] In a 1993 review of Artificial Intelligence ( Winston ) by Doris Appleby, the 1989 edition of LISP was reviewed in its role as a companion reference.
A native code compiler named "Python" (not to be confused with the Python programming language). If Common Lisp source code has been written with appropriate declarations and is organized with speed in mind the Python compiler generates code that is almost free from overhead compared to code compiled from languages like C++.
GNU Common Lisp (GCL) is the GNU Project's ANSI Common Lisp compiler, an evolutionary development of Kyoto Common Lisp. It produces native object code by first generating C code and then calling a C compiler. GCL is the implementation of choice for several large projects including the mathematical tools Maxima, AXIOM, HOL88, and ACL2.
