Regular Expression
A regular expression (shortened as regex or regexp; sometimes referred to as rational expression) is a sequence of characters that specifies a search pattern in text. Usually such patterns are used by string-searching algorithms for "find" or "find and replace" operations on strings, or for input validation. Regular expression techniques are developed in theoretical computer science and formal language theory. The concept of regular expressions began in the 1950s, when the American mathematician Stephen Cole Kleene formalized the concept of a regular language. They came into common use with Unix text-processing utilities. Different syntaxes for writing regular expressions have existed since the 1980s, one being the POSIX standard and another, widely used, being the Perl syntax. Regular expressions are used in search engines, in search and replace dialogs of word processors and text editors, in text processing utilities such as sed and AWK, and in lexical analysis.

Oniguruma
by K. Kosako is a BSD licensed regular expression library that supports a variety of character encodings. The Ruby programming language, in version 1.9, as well as PHP's multi-byte string module (since PHP5), use Oniguruma as their regular expression engine. It is also used in products such as Atom, EDK2 UEFI, GyazMail, Take Command Console, Tera Term, TextMate and SubEthaEdit. There is also a forked Oniguruma version called "Onigmo" (Oniguruma-mod) which includes some features introduced in Perl 5.10+. Ruby since version 2.0 has also switched to it and features have been backported from ruby to Onigmo. Take Command Console since version 20 has also switched to Onigmo.

HHVM
HipHop Virtual Machine (HHVM) is an open-source virtual machine based on just-in-time (JIT) compilation that serves as an execution engine for the Hack programming language and used to support PHP execution before the release of HHVM version 4. By using the principle of JIT compilation, Hack code is first transformed into intermediate HipHop bytecode (HHBC), which is then dynamically translated into x86-64 machine code, optimized, and natively executed. This contrasts with PHP's usual interpreted execution, in which the Zend Engine transforms PHP source code into opcodes that serve as a form of bytecode, and executes the opcodes directly on the Zend Engine's virtual CPU. HHVM is developed by Meta, with the project's source code hosted on GitHub; it is licensed under the terms of the PHP License and Zend License. Overview HHVM was created as the successor to the HipHop for PHP (HPHPc) PHP execution engine, which is a PHP-to-C++ transpiler also created by Facebook. Based ...

Julia (programming Language)
Julia is a high-level, dynamic programming language. Its features are well suited for numerical analysis and computational science. Distinctive aspects of Julia's design include a type system with parametric polymorphism in a dynamic programming language; with multiple dispatch as its core programming paradigm. Julia supports concurrent, (composable) parallel and distributed computing (with or without using MPI or the built-in corresponding to "OpenMP-style" threads), and direct calling of C and Fortran libraries without glue code. Julia uses a just-in-time (JIT) compiler that is referred to as "just- ahead-of-time" (JAOT) in the Julia community, as Julia compiles all code (by default) to machine code before running it. Julia is garbage-collected, uses eager evaluation, and includes efficient libraries for floating-point calculations, linear algebra, random number generation, and regular expression matching. Many libraries are available, including some (e.g., for fast Fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BBEdit
BBEdit is a proprietary text editor made by Bare Bones Software, originally developed for Macintosh System Software 6, and currently supporting macOS. History The first version of BBEdit was created as a "bare bones" text editor to serve as a "proof of concept"; the intention was to demonstrate the programming capabilities of an experimental version of Pascal for the Macintosh. The original prototypes of BBEdit used the TextEdit control available in versions of the classic Mac OS of the time. The TextEdit control could not load files larger than 32 KB. The Macintosh Pascal project was ultimately terminated, but the demonstration program was reworked to use the THINK Technologies "PE" text editing engine used for THINK C, which was much faster and could read larger files. BBEdit was the first freestanding text editor to use the "PE" editing engine, and is the only one still being developed. BBEdit was available at no charge upon its initial release in 1992 but was commercial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nginx
Nginx (pronounced "engine x" ) is a web server that can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache. The software was created by Igor Sysoev and publicly released in 2004. Nginx is free and open-source software, released under the terms of the 2-clause BSD license. A large fraction of web servers use Nginx, often as a load balancer. A company of the same name was founded in 2011 to provide support and ''Nginx Plus'' paid software. In March 2019, the company was acquired by F5, Inc. for $670 million. Popularity W3Tech's web server count of all web sites ranked Nginx first with 33.6%. Apache was second at 31.4% and Cloudflare Server third at 21.6%. , Netcraft estimated that Nginx served 22.01% of the million busiest websites with Apache a little ahead at 23.04%. Cloudflare at 19.53% and Microsoft Internet Information Services at 5.78% rounded out the top four servers for the busiest websites. Some of Netcraft's other statistics show Ngi ...

Apache HTTP Server
The Apache HTTP Server ( ) is a free and open-source cross-platform web server software, released under the terms of Apache License 2.0. Apache is developed and maintained by an open community of developers under the auspices of the Apache Software Foundation. The vast majority of Apache HTTP Server instances run on a Linux distribution, but current versions also run on Microsoft Windows, OpenVMS, and a wide variety of Unix-like systems. Past versions also ran on NetWare, OS/2 and other operating systems, including ports to mainframes. Originally based on the NCSA HTTPd server, development of Apache began in early 1995 after work on the NCSA code stalled. Apache played a key role in the initial growth of the World Wide Web, quickly overtaking NCSA HTTPd as the dominant HTTP server. In 2009, it became the first web server software to serve more than 100 million websites. , Netcraft estimated that Apache served 23.04% of the million busiest websites, while Nginx served 22. ...

Perl Compatible Regular Expressions
Perl Compatible Regular Expressions (PCRE) is a library written in C, which implements a regular expression engine, inspired by the capabilities of the Perl programming language. Philip Hazel started writing PCRE in summer 1997. PCRE's syntax is much more powerful and flexible than either of the POSIX regular expression flavors (BRE, ERE) and than that of many other regular-expression libraries. While PCRE originally aimed at feature-equivalence with Perl, the two implementations are not fully equivalent. During the PCRE 7.x and Perl 5.9.x phase, the two projects have coordinated development, with features being ported between them in both directions. In 2015 a fork of PCRE was released with a revised programming interface (API). The original software, now called PCRE1 (the 1.xx–8.xx series), has had bugs mended, but no further development. , it is considered obsolete, and the current 8.45 release is likely to be the last. The new PCRE2 code (the 10.xx series) has had a numb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SubEthaEdit
SubEthaEdit is a collaborative real-time editor designed for Mac OS X. The name comes from the Sub-Etha communication network in ''The Hitchhiker's Guide to the Galaxy'' series. History SubEthaEdit was first released under the name Hydra in early 2003 but, for legal reasons, the name was changed to SubEthaEdit in late 2004. The first version of Hydra was built in just a few months with the intent of winning an Apple Design Award, which it did at Apple's Worldwide Developers Conference 2003. In 2007, TheCodingMonkeys licensed the "Subetha Engine" to Panic for use in Coda. In June 2014, SubEthaEdit 4 was released, distributed exclusively in the Mac App Store. With version 5 released in 2019, the application became free and open source, under the MIT license. Features Apart from the usual text-editing capabilities, collaborative editing is one of SubEthaEdit's key features. The collaboration is document-based, non-locking, and non-blocking.
