Lisp Flowchart Example

In Common Lisp, a package is a namespace which contains symbols. The symbols can be defined in the package, like MAIN and GREET, or they can be symbols inherited from other packages, like DEFUN and FORMAT which both come from the COMMON-LISP package 2. The Hello World example should define a package, called HELLO.

2 Write a function non-nil which takes a list and replaces each non-null element with 1 and each null element with 0. Write it twice - once recursively and once using mapcar . Bonus problem write an expression that counts the number of non-null elements in a list.

LISP expressions are composed of forms. The most common LISP form is function application. LISP represents a function call f x as f x. For example, cos 0 is written as cos 0. LISP expressions are case-insensitive. It makes no difference whether we type cos 0 or COS 0. Similarly, quot quot is the name of the addition function that returns the sum of its arguments. Some functions, like

It's with great pleasure for me to share my guide notes on Common Lisp, prepared by compiling numerous textbooks and online sources. The purpose behind the notes was to create something concise that covered the main forms used in Lisp, and also some key notes on the concepts underpinning the language.

The LISP reader consists of three primary functions The function READ is used to parse input into Lisp objects and reads exactly one expression, regardless of newlines The function READ-LINE reads all characters up to a newline, returning a string The function READ-FROM-STRING takes a string and returns the first expression from it Below are some examples you can experiment with.

Common Lisp ANSI Standard The original Lisp Standard Draft dpANS3R version, now freely available. This is meant mainly for people who write Common Lisp Systems and Compilers. For the Application Programmer please see the Technical Reference.

This sample program illustrates the use of data abstraction in Lisp. The procedures to add and remove elements of the queue are independent of the implementation of the queue. The queue itself is implemented as a structure, a data object with a series of named slots. Lisp automatically creates functions to construct, access, and copy instances of a structure.
