भाषाएँ
+ उन प्रोग्रामन भाषाओं की सूची जिनमें रेग्युलर इक्सप्रेसन का उपयोग हुआ है। भाषा जालस्थल सॉफ्टवेयर लाइसेंस टिप्पणी .NET MSDN   POSIX C (C) libc/regex from BSD BSD According to regex(3), available from at least 4.4BSD (if not earlier) C++11 (C++) C++ standards website  Since ISO14822:2011(e) D D   Go Golang.org   Haskell Haskell.org  Omitted in the language report, and in GHC's Hierarchical Libraries Java Java  REs are written as strings in source code: all backslashes must be doubled, harming readability. जावास्क्रिप्ट (ECMAScript) ECMA-262  Limited but REs are first-class citizens of the language with a specific /.../mod syntax. Julia JuliaLang.org  REs are part of the language core library using PCRE built-in and an optional wrapper for (C code) ICU is available. Lua Lua.org  Uses simplified, limited dialect; can be bound to more powerful library, like PCRE or an alternative parser like LPeg. Mathematica Wolfram Proprietary Nim nim-lang.org  Standard library includes PCRE-based re and nre modules, as well as various alternatives (ex. strutils, pegs (Parsing Expression Grammar matching), strscans, parseutils, etc). Free Pascal (Object Pascal) www.freepascal.org  Free Pascal 2.6+ ships with TRegExpr from Sorokin and two other regular expression libraries; See wiki.lazarus.freepascal.org/Regexpr. OCaml Caml  , the standard module is generally regarded as deprecated; often recommended libraries are pcre (with full support for PCRE) and re (which is not as complete but claims better performance and provides frontends to popular syntaxes: PCRE, Perl, Posix, Emacs, shell globbing). Perl Perl.com  Full, central part of the language PHP PHP.net  Has two implementations, with PCRE being the more efficient in speed, functions Python python.org  Python has two major implementations, the built in re and the regex library. Ruby ruby-doc.org  Ruby 1.8 and 1.9 use different engines; 1.9 integrates Oniguruma. SAP ABAP SAP.com   Tcl tcl.tk  Tcl library doubles as a regular expression library. ActionScript 3 ActionScript Technology Center   Wolfram Language Wolfram Research Proprietary; usable for free on a limited scale on the Wolfram Development platform.

भाषाओं के प्रमुख विशेषताएँ
NOTE: An application using a library for regular expression support does not necessarily offer the full set of features of the library, e.g. GNU grep which uses PCRE does not offer lookahead support, though PCRE does.
