Since Forking from KJS and PCRE > 자유게시판

WebKit is a browser engine developed by Apple and primarily used in its Safari web browser, as well as all web browsers on iOS and iPadOS. WebKit is also used by the PlayStation consoles beginning from the PS3, the Tizen mobile operating systems, the Amazon Kindle e-book reader, Nintendo consoles beginning from the 3DS Internet Browser, and the discontinued BlackBerry Browser. 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. Bitstream, KDP (www.amazon.com) BlackBerry, Sony, Igalia, and others. WebKit supports macOS, Windows, Linux, and various other Unix-like operating systems. On April 3, 2013, Google announced that it had forked WebCore, a component of WebKit, to be used in future versions of Google Chrome and the Opera web browser, under the name Blink. WebCore and JavaScriptCore components, which are available under the GNU Lesser General Public License.

As of March 7, 2013, WebKit is a trademark of Apple, registered with the U.S. Patent and Trademark Office. The code that would become WebKit began in 1998 as the KDE HTML (KHTML) layout engine and KDE JavaScript (KJS) engine. KHTML and KJS allowed easier development than other available technologies by virtue of being small (fewer than 140,000 lines of code), cleanly designed and standards-compliant. KHTML and KJS was ported to macOS with the help of an adapter library and renamed WebCore and JavaScriptCore. JavaScriptCore was announced in an e-mail to a KDE mailing list in June 2002, alongside the first release of Apple's changes. The exchange of code between WebCore and KHTML became increasingly difficult as the code base diverged because both projects had different approaches in coding and code sharing. 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".

They claimed Apple submitted their changes in large patches containing multiple changes with inadequate documentation, often in relation to future additions to the codebase. Thus, these patches were difficult for the KDE developers to integrate back into KHTML. 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. 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 WebCore 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. 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 Acid2 rendering test.

Following the appearance of a story of the fork in the news, Apple released the source code of the WebKit fork in a public revision-control repository. The WebKit team had also reversed many Apple-specific changes in the original WebKit code base and implemented platform-specific abstraction layers to make committing the core rendering code to other platforms significantly easier. In July 2007, Ars Technica reported that the KDE team would move from KHTML to WebKit. Instead, after several years of integration, KDE Development Platform version 4.5.0 was released in August 2010 with support for both WebKit and KHTML, and development of KHTML continues. On June 7, 2005, Safari developer Dave Hyatt announced on his weblog that Apple was open-sourcing WebKit (formerly, only WebCore and JavaScriptCore were open source) and opening up access to WebKit's revision control tree and the issue tracker. In mid-December 2005, support for Scalable Vector Graphics (SVG) was merged into the standard build. WebKit's JavaScriptCore and WebCore components are available under the GNU Lesser General Public License, while the rest of WebKit is available under the BSD 2-Clause license.
