For information on the programming language Whitespace, see Whitespace programming language. For white space in graphic design, see white space. A programming language or computer language is a standardized communication technique for expressing instructions to a computer. ... Whitespace is an esoteric programming language developed by Edwin Brady and Chris Morris. ... In graphic design and desktop publishing the effective use of white space is one of the principles of design. ...

In computer science, a whitespace (or a whitespace character) is any character which does not display itself but does take up space. For example, the character symbol " ", which is a blank space. Whitespaces are generated by the space bar or the Tab key; depending on context, a line-break generated by the Return key (Enter key) may be considered whitespace as well.

Originally, carriage return was the term for the key, lever, or mechanism in general that would cause the cylinder on which the paper was held (the carriage) to return to the left after a line of text had been typed, and would often move it down a line as well. ... Originally, carriage return was the term for the key, lever, or mechanism on a typewriter that would cause the cylinder on which the paper was held (the carriage) to return to the left side of the paper after a line of text had been typed, and would often move it...

Whitespace can also refer to a series of whitespace characters. Within source code, the size of whitespace is generally ignored by free-form languages. But for example in the Haskell programming language or the Python programming language whitespace and indentation are used for syntactical purposes. Source code (commonly just source or code) is any series of statements written in some human-readable computer programming language. ... In computer programming, a free-form language is a programming language in which the positioning of characters on the page in program text is not significant. ... Haskell logo Haskell is a standardized pure functional programming language with non-strict semantics. ... Python is an interpreted, interactive programming language created by Guido van Rossum in 1990. ...

In many programming languages abundant use of whitespace, especially trailing whitespace at the end of lines, is considered a nuisance. In interpreted languages, parsing of unnecessary whitespace may affect the speed of execution. In markup languages like HTML, unnecessary whitespace increases the file size, and may so affect the speed of transfer over a network. In computer programming, an interpreted language is a programming language whose programs may be executed from source form, by an interpreter. ... A specialized markup language using SGML is used to write the electronic version of the Oxford English Dictionary. ... In computing, HyperText Markup Language (HTML) is a markup language designed for the creation of web pages and other information viewable in a browser. ...

On the other hand, unnecessary whitespace can also inconspicuously mark code, similar to, but less obvious than comments in code. This can be desirable to prove an infringement of license or copyright, which was committed by copying and pasting. In a legal context, an infringement refers to the violation of a law or a right. ... This page is about computer text editing. ...

[ t]+ is a regular expression that matches whitespace. A regular expression (abbreviated as regexp, regex, or regxp, with plural forms regexps, regexes, or regexen) is a string that describes or matches a set of strings, according to certain syntax rules. ...

The term whitespace is based on the assumption that the background color used for text is white, and is thus confusing if it is not.
