    The matching algorithms of the library are based on the PCRE library, but not all of the PCRE library is interfaced and some parts of the library go beyond what PCRE offers. Currently PCRE version 8.40 (release date 2017-01-11) is used. Erlang: erlang.org: Apache 2.0: Standard library includes PCRE-based re module. The matching algorithms of ...

    Here, the first n is a single variable pattern, which will match absolutely any argument and bind it to name n to be used in the rest of the definition. In Haskell (unlike at least Hope ), patterns are tried in order so the first definition still applies in the very specific case of the input being 0, while for any other argument the function ...

    More generally, an equation E=F between regular-expression terms with variables holds if, and only if, its instantiation with different variables replaced by different symbol constants holds. [30] [31] Every regular expression can be written solely in terms of the Kleene star and set unions over finite words. This is a surprisingly difficult ...

    en.wikipedia.org/wiki/Software_release_life_cycle

    The software release life cycle is the process of developing, testing, and distributing a software product (e.g., an operating system). It typically consists of several stages, such as pre-alpha, alpha, beta, and release candidate, before the final version, or "gold", is released to the public. An example of a basic software release life cycle

  8. ReDoS - Wikipedia

    en.wikipedia.org/wiki/ReDoS

    This happens when a regular expression has three properties: the regular expression applies repetition (+, *) to a subexpression; the subexpression can match the same input in multiple ways, or the subexpression can match an input string which is a prefix of a longer possible match;
