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 ...
LISP is a university textbook on the Lisp programming language, written by Patrick Henry Winston and Berthold Klaus Paul Horn. It was first published in 1981, and the third edition of the book was released in 1989. [1] The book is intended to introduce the Lisp programming language and its applications. [2]: Preface
List comprehension is a syntactic construct available in some programming languages for creating a list based on existing lists. It follows the form of the mathematical set-builder notation (set comprehension) as distinct from the use of map and filter functions.
It has many of the features of Lisp Machine Lisp (a large Lisp dialect used to program Lisp Machines), but was designed to be efficiently implementable on any personal computer or workstation. Common Lisp is a general-purpose programming language and thus has a large language standard including many built-in data types, functions, macros and ...
Lisp. McCarthy's original notation used bracketed "M-expressions" that would be translated into S-expressions. As an example, the M-expression car[cons[A,B]] is equivalent to the S-expression (car (cons A B)). Once Lisp was implemented, programmers rapidly chose to use S-expressions, and M-expressions were abandoned. M-expressions surfaced
On Lisp: Advanced Techniques for Common Lisp is a book by Paul Graham on macro programming in Common Lisp. Published in 1993, it is currently out of print, [ 1 ] but can be freely downloaded as a PDF file.
Lisp programs are valid S-expressions, but not all S-expressions are valid Lisp programs. (1.0 + 3.1) is a valid S-expression, but not a valid Lisp program, since Lisp uses prefix notation and a floating point number (here 1.0) is not valid as an operation (the first element of the expression).
Hy is a dialect of the Lisp programming language designed to interact with Python by translating s-expressions into Python's abstract syntax tree (AST). [2] [3] Hy was introduced at Python Conference (PyCon) 2013 by Paul Tagliamonte. [4] Lisp allows operating on code as data (metaprogramming), thus Hy can be used to write domain-specific ...
