Lisp operators – Roger Johansson Blog

rogerjohansson.blog02/02/2008 · Lisp operators. February 2, 2008 Roger Johansson Domain Specific Languages Leave a comment. I just got home from a conference with my new job, a little bit tipsy and couldn’t sleep. So I decided to add some new features to my Lisp clone. I’ve made it possible to set operator priority for functions. Eg. (operator-priority + 1) (operator-priority – 1) (operator-priority * 2) (operator-priority / 2)

override/overload the + operator to operate on common lisp …

stackoverflow.comWhile operator overloading is OK in other languages, and generic functions is OK in some cases in Common lisp, making + generic is useless in Common Lisp. You can easily solve your problem with map , as I showed, or if you really need one function to process numbers and vectors, then create new one.

cons – Wikipedia

en.wikipedia.orgIn Lisp, lists are implemented on top of cons pairs. More specifically, any list structure in Lisp is either: An empty list (), which is a special object usually called nil.; A cons cell whose car is the first element of the list and whose cdr is a list containing the rest of the elements.; This forms the basis of a simple, singly linked list structure whose contents can be manipulated with cons, car, and cdr.Note that nil is the only …

Arithmetic Operations – GNU Emacs Lisp Reference Manual

gnu.orgEmacs Lisp arithmetic functions do not check for integer overflow. Thus (1+ 536870911) may evaluate to −536870912, depending on your hardware. — Function: 1+ number-or-marker. … ⇒ 4 (1+ foo) ⇒ 5 This function is not analogous to the C operator ++—it does not increment a variable. It just computes a sum. Thus, if we continue, foo ⇒ 4 If you want to increment the variable, you must use setq, like this: (setq …

The Special Operators – gigamonkeys

gigamonkeys.com1 Of course, if IF wasn’t a special operator but some other conditional form, such as COND, was, you could build IF as a macro. Indeed, in many Lisp dialects, starting with McCarthy’s original Lisp, COND was the primitive conditional evaluation operator. 2 Well, technically those constructs could also expand into a LAMBDA expression since, as I mentioned in Chapter 6, LET could be defined–and was in …

Common LISP Tutorial

silp.iiita.ac.in• In Lisp, the special constant. nil (case insensitive) all by itself represents "false". Every other expression but . nil. is considered to be “true”. • Expressions always in Prefix form. • In Lisp, nearly everything is a function. Even the mathematical operators. For example: (+ (* 2 3) 1) equals 7.

Equality in Lisp – Eli Bendersky’s website

eli.thegreenplace.net08/08/2004 · Lisp has a few operators (or functions, or predicates, whatever you prefer to call them) for equality testing, which can be very confusing. This article’s aim is to clarify the uses of, and emphasize the differences between eq, eql, equal, equalp and =.I try to provide plenty of examples, to cover most of the useful cases where equality operators are applied.
