Web. Kit - Wikipedia. Web. Kit is a layout enginesoftware component for renderingweb pages in web browsers. It powers Apple's Safari web browser. Web. Kit is also the basis for the experimental browser included with the Amazon. Kindlee- book reader, and for the default browser in Applei. OS, Black. Berry Browser in OS 6 and above, and Tizen mobile operating systems. Web. Kit's C++application programming interface (API) provides a set of classes to display web content in windows, and implements browser features such as following links when clicked by the user, managing a back- forward list, and managing a history of pages recently visited. Web. Kit's HTML and Java. Script code was originally a fork of the KHTML and KJS libraries from KDE,[1][6] and has now been further developed by individuals from KDE, Apple, Google, Nokia, Bitstream, Black. Berry, Igalia, and others.[7]mac. OS, Windows, Linux, and some other Unix- likeoperating systems are supported by the project.[8] On April 3, 2. Portable XLR Recorder (optional): If you plan on using analog microphones for your podcast, you’ll need something that captures your analog audio and converts it to. WebKit is used as the rendering engine within Safari and was formerly used by Google's Chrome web browser on Windows, macOS, iOS, and Android before version 4.4. After rumors spread on Reddit that Verizon Wireless customers were unable to achieve feeds of faster than 10Mbps while connected to Netflix, the company confirmed to.Google announced that it had forked Web. Core, a component of Web. Kit, to be used in future versions of Google Chrome and the Opera web browser, under the name Blink.[9][1. Web. Kit is available under a BSD- form license[1. Web. Core and Java. Script. Core components, which are available under the GNU Lesser General Public License. As of March 7, 2. Web. Kit is a trademark of Apple, registered with the U. S. Patent and Trademark Office.[1. Origins[edit]The code that would become Web. Kit began in 1. 99. KDE HTML (KHTML) layout engine and KDE Java. Script (KJS) engine. The Web. Kit project was begun within Apple by Don Melton on June 2. KHTML and KJS. Melton explained in an e- mail to KDE developers[1] that KHTML and KJS allowed easier development than other available technologies by virtue of being small (fewer than 1. KHTML and KJS were ported to OS X with the help of an adapter library and renamed Web. Core and Java. Script. Core.[1] Java. Script. Core was announced in an e- mail to a KDE mailing list in June 2. Apple's changes.[1. Web. Core was announced at the Macworld Expo in January 2. Apple CEOSteve Jobs with the release of the Safari web browser. Java. Script. Core was first included with Mac OS X v. Apple used in their Sherlock application, while Web. Core debuted with the first beta of Safari. Mac OS X v. 10. 3 was the first major release of Apple's operating system to bundle Web. Kit, although it had already been bundled with a minor release of 1. According to Apple, some changes involved OS X- specific features (e. Objective- C, KWQ,[1. OS X calls) that are absent in KDE's KHTML, which called for different development tactics.[1. Split development[edit]The exchange of code between Web. Core and KHTML became increasingly difficult as the code base diverged because both projects had different approaches in coding and code sharing.[1. At one point KHTML developers said they were unlikely to accept Apple's changes and claimed the relationship between the two groups was a "bitter failure".[1. Apple submitted their changes in large patches containing very many changes with inadequate documentation, often to do with future additions. Thus, these patches were difficult for the KDE developers to integrate back into KHTML.[1. Also, Apple had demanded that developers sign non- disclosure agreements before looking at Apple's source code and even then they were unable to access Apple's bug database.[2. During the publicized "divorce" period, KDE developer Kurt Pfeifle (pipitas) posted an article claiming KHTML developers had managed to backport many (but not all) Safari improvements from Web. Core to KHTML, and they always appreciated the improvements coming from Apple and still do so. The article also noted Apple had begun to contact KHTML developers about discussing how to improve the mutual relationship and ways of future cooperation.[2. In fact, the KDE project was able to incorporate some of these changes to improve KHTML's rendering speed and add features, including compliance with the Acid. Since the story of the fork appeared in news, Apple has released changes of the source code of Web. Kit fork in a public revision- control repository.[2. Since the transfer of the source code into a public Concurrent Versions System (CVS) repository, Apple and KHTML developers have had increasing collaboration. Many KHTML developers have become reviewers and submitters for Web. Kit revision control repository. The Web. Kit team had also reversed many Apple- specific changes in the original Web. Kit code base and implemented platform- specific abstraction layers to make committing the core rendering code to other platforms significantly easier.[2. In July 2. 00. 7, Ars Technica reported that the KDE team would move from KHTML to Web. Kit.[2. 5] Instead, after several years of integration, KDE Development Platform version 4. August 2. 01. 0 with support for both Web. Kit and KHTML, and development of KHTML continues.[2. Open- sourcing[edit]On June 7, 2. Safari developer Dave Hyatt announced on his weblog that Apple was open- sourcing Web. Kit (formerly, only Web. Core and Java. Script. Core were open source) and opening up access to Web. Kit's revision control tree and the issue tracker.[2. This was announced at Apple's Worldwide Developers Conference 2. Apple Senior Vice President of Software Engineering Bertrand Serlet. In mid- December 2. Scalable Vector Graphics (SVG) was merged into the standard build[2. January 2. 00. 6 the source code was migrated from Concurrent Versions System (CVS) to Subversion (SVN). Web. Kit's Java. Script. Core and Web. Core components are available under the GNU Lesser General Public License, while the rest of Web. Kit is available under a BSD- style license. Further development[edit]Beginning in early 2. Cascading Style Sheets (CSS) extensions, including animation, transitions and both 2. D and 3. D transforms; [2. World Wide Web Consortium (W3. C) in 2. 00. 9 for standardization.[2. In November 2. 00. HTML5 draft specification, allowing embedded video to be natively rendered and script- controlled in Web. Kit.[3. 0]On June 2, 2. Web. Kit project announced they rewrote Java. Script. Core as "Squirrel. Fish", a bytecodeinterpreter.[3. The project evolved into Squirrel. Fish Extreme (abbreviated SFX), announced on September 1. Java. Script into native machine code, eliminating the need for a bytecode interpreter and thus speeding up Java. Script execution.[3. Initially, the only supported processor architecture for SFX was the x. January 2. 00. 9, SFX was enabled for OS X on x. Web. Kit. 2[edit]On April 8, 2. Web. Kit. 2 was announced to redesign Web. Kit. The goal is to abstract the components that provide web rendering cleanly from their surrounding interface or application shell, creating a situation where, "web content (Java. Script, HTML, layout, etc) lives in a separate process from the application UI". This abstraction is intended to make reuse a more straightforward process for Web. Kit. 2 than for Web. Kit. Web. Kit. 2 has "an incompatible API change from the original Web. Kit", which motivated its name change.[3. Web. Kit. 2 will target Mac, Windows, GTK+, and Mee. Go- Harmattan.[3. Safari for OS X switched to the new API with version 5. Safari for i. OS switched to Web. Kit. 2 since i. OS 8.[3. Web. Kit is used as the rendering engine within Safari and was formerly used by Google's Chrome web browser on Windows, mac. OS, i. OS, and Android before version 4. Kit. Kat (Chrome used only Web. Core, and included its own Java. Script engine named V8 and a multiprocess system).[4. Other applications on mac. OS make use of Web. Kit, such as Apple's e- mail client Mail and the 2. Microsoft's Entouragepersonal information manager, both of which make use of Web. Kit to render e- mail messages with HTML content. Installed base[edit]New web browsers have been built around Web. Kit such as the S6. Symbian mobile phones, Black. Berry Browser (ver 6. Midori, Chrome browser,[4. Android Web browser before version 4. Kit. Kat, and the browser used in Play. Station 3 system software from version 4. KDE's Rekonq web browser and Plasma Workspaces also use it as the native web rendering engine. Web. Kit has been adopted as the rendering engine in Omni. Web, i. Cab and Web (formerly named Epiphany) and Sleipnir, replacing their original rendering engines. GNOME's Web supported both Gecko and Web. Kit for some time, but the team decided that Gecko's release cycle and future development plans would make it too cumbersome to continue supporting it.[4.
