For an introduction on how to set them all up, you can have a look at this guide. Clojure is not designed to be backwards compatible downloar other Lisp dialects. The potential small size of a useful Scheme interpreter makes it particularly popular for embedded scripting.
Lisp was the first language where the structure of program software is represented faithfully and directly in a standard data structure—a quality much later dubbed " homoiconicity ". Thus, Lisp functions can be manipulated, altered or even created within a Lisp program without lower-level manipulations. This is download considered one of the main advantages of the language programming regard to its expressive power, and makes the language suitable for syntactic macros and metacircular evaluation.
A conditional using an if—then—else syntax was invented by McCarthy in a Fortran context. For Lisp, McCarthy used the more language cond -structure. Lisp deeply influenced Alan Kaythe leader of the research team that developed Smalltalk at Xerox PARC ; and in turn Lisp was influenced by Smalltalk, with later dialects adopting object-oriented programming features inheritance classes, encapsulating instances, message passing, etc.
The Flavors object system introduced the concept of multiple inheritance and the mixin. The Common Lisp Object System provides multiple inheritance, multimethods with multiple dispatchand first-class generic functionsyielding a flexible and powerful form of dynamic dispatch. It programimng served as the template for many subsequent Lisp including Scheme object systems, which are often implemented via a metaobject protocol languabe, a reflective metacircular design in which the object system is defined in terms of itself: Lisp was only the second llsp after Smalltalk and is still one of the very few languages to possess such a metaobject system.
Many years later, Alan Lisp suggested that as a result of the confluence of these features, only Smalltalk and Lisp could be regarded as properly conceived object-oriented programming systems.
Lisp introduced the concept of automatic garbage collectionin language the system walks languaeg heap looking for unused memory. Progress in modern sophisticated garbage collection download such as generational garbage collection was stimulated by its use in Lisp. Edsger W. Dijkstra in his Turing Award lecture said. Largely because of its resource requirements with respect to early computing hardware including early programmingLisp did not become as popular outside of the Softawre community as Fortran and the ALGOL -descended C language.
Because of its suitability to complex and dynamic applications, Lisp is enjoying some resurgence of popular interest in the s. Lisp is an expression lidp language. Unlike most other languages, no distinction is made between "expressions" and "statements" ; [ dubious — discuss ] all code and data are written as expressions. When an expression is evaluatedit produces a value in Common Lisp, possibly multiple valuessoftware can then be embedded programmjng other expressions.
Each value can be any data type. Lisp paper introduced two types of syntax: Symbolic expressions S-expressionssexpswhich mirror the internal representation of code and data; and Meta expressions M-expressionswhich express functions of S-expressions.
M-expressions never found favor, and almost all Lisps today use S-expressions to manipulate both code and data. The use of parentheses is Lisp's most immediately obvious difference from other programming language families. However, the syntax of Lisp is not limited to traditional parentheses notation. It can be extended to include alternative notations. The reliance on expressions gives the language great flexibility.
Because Lisp functions are written as lists, they can be processed exactly like data. This allows easy writing of programs which manipulate other programs metaprogramming. Many Lisp dialects exploit this feature using macro systems, which enables extension of the language almost without limit. A Lisp langkage is written with its elements separated by fownloadand surrounded by parentheses.
For example, 1 2 foo is a list whose elements are the three atoms 12and foo. These values are implicitly typed: they are programmjng two integers and a Languqge data type called a "symbol", and do not have to be declared as such. The empty list is also represented as the special atom nil. This is the only entity in Lisp which is both an atom and a list.

Expressions are written as lists, using prefix notation. The first element in the list is the name of a function, the name of a macro, a lambda expression or the name of a pgogramming operator" see below. The remainder of the list are the arguments. For example, the function list returns its arguments as a list, so the expression.
Lisp (programming language) - Wikipedia
The "quote" before the foo in the preceding example is a "special operator" which returns its argument without evaluating it. Any unquoted expressions are recursively evaluated before the enclosing expression is prrogramming. For example. Note that the third argument is a list; lists can be nested. Lisp has no notion of operators as implemented in Algol-derived languages. Arithmetic operators in Lisp are variadic functions or n-aryable to take any number of arguments.LispWorks ® for Windows ®.

Lisp was the natural language to start with. We needed to write lots of code very quickly; and we needed the higher-level power that only Lisp and Allegro CL provides. Lisp provided us with the ability to write the algorithms that we needed.
For example, the special operator if takes three arguments. If the first argument is non-nil, it evaluates to the second argument; otherwise, it evaluates to the third argument. Thus, lksp expression. Of course, this would be more useful if a non-trivial expression llisp been substituted in place of nil. Lisp also provides logical language andor and not.
The and and or operators do short-circuit evaluation and lisp return their first nil and non-nil argument respectively. Another special operator, lambdais used to bind variables to values which are then evaluated within an expression. This operator is also used to create functions: the arguments to lambda are a list of arguments, and the programming or expressions to which the function evaluates the returned value is the value of the last expression that is evaluated.
The expression. Lambda expressions are treated software differently from named languzge they are invoked the same way. Therefore, the expression. Here, we're doing a function application: we execute the anonymous function by passing to it the value 5. Named functions are created by storing a lambda expression in a symbol using the defun macro.
It is conceptually similar to the expression:. In the original LISP there were two fundamental data types : atoms and lists. A list softwwre a finite ordered sequence of elements, where each oisp is either an atom or a list, and an atom was a number or a symbol. A symbol was essentially a unique named item, written as an alphanumeric string in source code download, and used either as a variable name or as a data item in symbolic processing.
The essential difference between atoms and lists was that atoms were lanbuage and unique.
Two atoms that appeared in different places in source code but were written in exactly the same way represented the same object, [ citation needed ] whereas each list was a separate object that could be altered programning of other lists and could be distinguished from other lists by comparison operators. As more data types were introduced in later Lisp dialects, and programming styles evolved, the concept of an atom lost importance.
A Lisp list is implemented as a singly linked list. These are respectively equivalent to the data and next fields discussed in the article linked list. Of the many data structures that can be built out of cons cells, one of the most basic is called a proper list. A proper list is either the special nil empty list lanfuage, or a cons in which the car points to a datum which may be another cons structure, such as a listand the cdr points to another proper list.

If a given cons is taken to be the head of a linked list, then its car points to the first element of the list, and its cdr points to the rest of the list. For language reason, the car and cdr functions are also called first and rest when referring to conses download are part of a linked list rather than, say, a tree. A list is nothing more than an aggregate of linked conses. A variable that refers to a given list is simply a pointer to the first cons in the list.
Traversal of a list can be done by cdring down the list; that is, taking successive cdrs to visit each cons of the list; or by using any of several higher-order functions to map a function over a list. Because conses and lists are so universal software Lisp systems, it is a common misconception that they are Lisp's only data structures. In fact, all but lisp most simplistic Lisps have other data structures, such as vectors arrayshash tablesstructures, and so forth.
Parenthesized S-expressions represent linked list structures. There are several ways to represent the same list as an S-expression. A cons can be written in dotted-pair notation as a. A longer proper list might be written a. This is conventionally abbreviated as a b c d in list notation. An improper list  may be written in a combination of the two — as a b c. Lisp provides many built-in procedures for accessing and controlling lists.
Lists can be created directly with the list procedure, which takes any number of arguments, and returns the list of these arguments. Because of the way that lists are constructed from cons pairsthe cons procedure can be used to add programming element to the front of a list. Note that the cons procedure is asymmetric in how it handles list arguments, because of how lists are constructed. The append procedure appends two or more lists to one another.
Lisp lists, softwafe simple linked lists, can share structure with one another. That is to say, two lists can have the same tailor final sequence of conses. For instance, after the execution of the following Common Lisp code:. However, the tail b c is the same structure in both lists. It is not a copy; the cons cells pointing to b and c are in the same memory locations for both lists.
Sharing structure rather than copying can give a dramatic performance improvement. However, this technique can interact in undesired ways with functions that alter lists passed to them as arguments. Altering one list, such as by replacing the c with a goosewill affect the other:. This changes foo to a b goosebut thereby also changes bar to x b goose — a possibly unexpected result. This can be a source of bugs, and functions which alter their arguments are documented as destructive for this very reason.

Aficionados of functional programming avoid destructive functions. In the Scheme dialect, which favors the functional style, the names of destructive functions are marked with a cautionary exclamation point, or "bang"—such as set-car!Lisp is the second-oldest high-level programming language after Fortran and has changed a great deal since its early days, and a number of dialects have existed over its history.

In the Common Lisp dialect, destructive functions are commonplace; the equivalent of set-car! This function is rarely seen, however, as Common Lisp includes a special facility, setfto make it easier to define and use destructive functions. A frequent style in Common Lisp is to write code functionally without destructive calls when prototyping, then to add destructive calls as an optimization where it is safe to do so.
Lisp evaluates expressions which are entered by the user. However, most other forms evaluate to themselves: if entering 5 into Lisp, it returns 5. Any expression can also be marked to prevent it from being evaluated as is necessary for symbols and lists. This is the role of the quote special operator, or its abbreviation ' one quotation mark. For instance, usually if entering the symbol fooit returns the value of the corresponding variable or an error, if there is no such variable.
To refer to the literal symbol, enter quote foo or, usually, 'foo. This is almost the same as the plain quote, except it allows expressions to be evaluated and their values interpolated into a quoted list with the commaunquote and comma-atsplice operators. The backquote is most often used in defining macro expansions. Self-evaluating forms and quoted forms are Lisp's equivalent of literals. It may be possible to modify the values of mutable literals in program code.
