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 ...
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 ...
ECL includes a bytecode interpreter and compiler. It can also compile Lisp code to machine code via a C compiler. ECL then compiles Lisp code to C, compiles the C code with a C compiler and can then load the resulting machine code. It is also possible to embed ECL in C programs, and C code into Common Lisp programs. GNU Common Lisp (GCL) The ...
In simplistic Lisp implementations, this list structure is directly interpreted to run the program; a function is literally a piece of list structure which is traversed by the interpreter in executing it. However, most substantial Lisp systems also include a compiler. The compiler translates list structure into machine code or bytecode for ...
Open-source Lisp dialect; runs on Linux and other POSIX-compliant systems; most prominent features are simplicity and minimalism [31] Portable Standard Lisp: 1980: University of Utah: Tail-recursive dynamically bound Lisp dialect inspired by its predecessor, Standard Lisp and the Portable Lisp Compiler; it implements the Reduce computer algebra ...
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).
In the usual parenthesized syntax of Lisp, an S-expression is classically defined [1] as an atom of the form x, or; an expression of the form (x. y) where x and y are S-expressions. This definition reflects LISP's representation of a list as a series of "cells", each one an ordered pair. In plain lists, y points to the next cell (if any), thus ...
[2] [3] 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. [2]
