A whitespace character is a character data element that represents white space when text is rendered for display by a computer. For example, a space character ( U+0020 SPACE , ASCII 32) represents blank space such as a word divider in a Western script .
Lisp and other S-expression-based languages do not differentiate statements from expressions, and parentheses are enough to control the scoping of all statements within the language. As in curly bracket languages, whitespace is mostly ignored by the reader (i.e., the read function). Whitespace is used to separate tokens. [5]
For example, PHP and Python allow this optional parameter, while Pascal and Java do not. With Common Lisp's string-trim function, the parameter (called character-bag ) is required. The C++ Boost library defines space characters according to locale , as well as offering variants with a predicate parameter (a functor ) to select which characters ...
Python. The use of the triple-quotes to comment-out lines of source, does not actually form a comment. [19] The enclosed text becomes a string literal, which Python usually ignores (except when it is the first statement in the body of a module, class or function; see docstring). Elixir
As a consequence of its syntax, Whitespace source code can be contained within the whitespace of code written in a language that ignores whitespace – making the text a polyglot. [2] Whitespace is an imperative, stack-based language. The programmer can push arbitrary-width integer values onto a stack and access a heap to store data.
Since there is no added white space built into a typical full stop (period), other than that above the full stop itself, full stops contribute to the river effect in a limited way. At one time, common word-processing software adjusted only the spacing between words, which was a source of the river problem.
Sometimes, a minor fix will help eliminate or reduce whitespace. This may involve adding or removing one blank line from some part of the page, re-ordering templates, or the use of a gallery for multiple images. If an embedded list creates white space, using two or more columns may solve the problem.
The zero-width space (​), abbreviated ZWSP, is a non-printing character used in computerized typesetting to indicate where the word boundaries are, without actually displaying a visible space in the rendered text.
