  2. Regular expression - Wikipedia

    en.wikipedia.org/wiki/Regular_expression

    Matches any single character (many applications exclude newlines, and exactly which characters are considered newlines is flavor-, character-encoding-, and platform-specific, but it is safe to assume that the line feed character is included). Within POSIX bracket expressions, the dot character matches a literal dot.

  3. Help:Searching/Regex - Wikipedia

    en.wikipedia.org/wiki/Help:Searching/Regex

    A regex search scans the text of each page on Wikipedia in real time, character by character, to find pages that match a specific sequence or pattern of characters. Unlike keyword searching, regex searching is by default case-sensitive, does not ignore punctuation, and operates directly on the page source (MediaWiki markup) rather than on the ...

    en.wikipedia.org/.../Regular_expression

    Greed, in regular expression context, describes the number of characters which will be matched (often also stated as "consumed") by a variable length portion of a regular expression – a token or group followed by a quantifier, which specifies a number (or range of numbers) of tokens. If the portion of the regular expression is "greedy", it ...

  5. Wildcard character - Wikipedia

    en.wikipedia.org/wiki/Wildcard_character

    In regular expressions, the period (., also called "dot") is the wildcard pattern which matches any single character. Combined with the asterisk operator .* it will match any number of any characters. In this case, the asterisk is also known as the Kleene star.

    en.wikipedia.org/wiki/Help:Searching/Features

    find wildcard expressions and regular expressions. A search matches what you see rendered on the screen and in a print preview. The raw "source" wikitext is searchable by employing the insource parameter. For these two kinds of searches a word is any string of consecutive letters and numbers matching a whole word or phrase.

  7. Matching wildcards - Wikipedia

    en.wikipedia.org/wiki/Matching_wildcards

    In computer science, an algorithm for matching wildcards (also known as globbing) is useful in comparing text strings that may contain wildcard syntax. [1] Common uses of these algorithms include command-line interfaces, e.g. the Bourne shell [2] or Microsoft Windows command-line [3] or text editor or file manager, as well as the interfaces for some search engines [4] and databases.

La, or aw? matches any single character ?at: Cat, cat, Bat or bat: at [abc] matches one character given in the bracket [CB]at: Cat or Bat: cat, bat or CBat [a-z]

  9. Pattern matching - Wikipedia

    en.wikipedia.org/wiki/Pattern_matching

    The wildcard pattern (often written as _) is also simple: like a variable name, it matches any value, but does not bind the value to any name. Algorithms for matching wildcards in simple string-matching situations have been developed in a number of recursive and non-recursive varieties. [10]
