Editing KHTML (section)

==History==
===Origins===
KHTML was preceded by an earlier engine called ''khtmlw'' or ''the KDE HTML Widget'', developed by Torben Weis and Martin Jones,<ref name="auto">{{cite web |url=https://www.youtube.com/watch?v=Tldf1rT0Rn0 |title=Lars Knoll and George Staikos: From KDE to WebKit |date=26 August 2011 |publisher=[[YouTube]] |access-date=1 September 2019}}</ref><ref>{{cite web |url=https://github.com/KDE/kde1-kdelibs |title=KDE/kde1-kdelibs/khtmlw |website=GitHub |language=en |access-date=2020-01-23}}</ref> which implemented support for [[HTML]] 3.2, [[HTTP]] 1.0, and [[Frame (World Wide Web)|HTML frames]], but not the [[Document Object Model|DOM]], [[Cascading Style Sheets|CSS]], or [[JavaScript]].

KHTML itself came into existence on November 4, 1998,<ref name="auto"/> as a [[fork (software development)|fork]] of the khtmlw library, with some slight refactoring and the addition of [[Unicode]] support and changes to support the move to [[Qt (software)|Qt]] 2.

===Re-write and improvement===
The real work on KHTML actually started between May and October 1999, with the realization that the choice facing the project was "either do a significant effort to move KHTML forward or to use [[Mozilla]]"<ref name="auto"/> and with adding support for [[JavaScript]] as the highest priority. So in May 1999, Lars Knoll<ref>{{cite web |url=https://behindkde.org/node/145/ |title=Lars Knoll &#124; Behind KDE |website=Behindkde.org |access-date=1 September 2019}}</ref> began doing research with an eye toward implementing the [[Document Object Model|DOM]] specification, finally announcing<ref>{{cite web |url=https://marc.info/?l=kfm-devel&m=93489518402924 |title='changes in KHTML' - MARC |website=Marc.info |access-date=1 September 2019}}</ref> on August 16, 1999 that he had checked in<ref>{{cite web |url=https://marc.info/?l=kde-commits&m=93476738632582 |title='khtml_to_dom: kdelibs/khtml' - MARC |website=Marc.info |access-date=1 September 2019}}</ref> what amounted to a complete rewrite of the KHTML library—changing KHTML to use the standard [[Document Object Model|DOM]] as its internal document representation. That in turn allowed the beginnings of [[JavaScript]] support to be added in October 1999,<ref name="auto"/> followed shortly afterwards with the integration of [[KJS (JavaScript engine)|KJS]] by [[Harri Porten]].

In the closing months of 1999 and first few months of 2000, Knoll did further work with Antti Koivisto and Dirk Mueller<ref name="auto"/><ref>{{cite web |url=http://trac.webkit.org/projects/webkit/wiki/WebKit%20Team#AnttiKoivistoanttikreview |title=WebKit Team – WebKit |website=Trac.webkit.org |access-date=1 September 2019}}</ref><ref>{{cite web |url=https://behindkde.org/node/211/ |title=Dirk Mueller &#124; Behind KDE |website=Behindkde.org |access-date=1 September 2019}}</ref> to add CSS support and to refine and stabilize the KHTML architecture,<ref name="auto"/> with most of that work being completed by March 2000. Among other things, those changes enabled KHTML to become the second browser after [[Internet Explorer]] to correctly support [[Hebrew]] and [[Arabic]] and languages written [[Bi-directional text|right-to-left]]<ref name="auto"/>—before [[Mozilla]] had such support.

[[KDE 2.0]] was the first KDE release (on October 23, 2000) to include KHTML<ref>{{cite web |url=https://www.youtube.com/watch?v=Tldf1rT0Rn0 |title=Lars Knoll and George Staikos: From KDE to WebKit |date=26 August 2011 |publisher=[[YouTube]] |access-date=1 September 2019}}</ref> (as the rendering engine of the new [[Konqueror]] [[file manager|file]] and [[web browser]], which replaced the monolithic KDE File Manager).

===Other modules===
KSVG was first developed in 2001 by Nikolas Zimmermann and Rob Buis; however, by 2003, it was decided to fork the then-current KSVG implementation into two new projects: [[KDOM (module)|KDOM]]/KSVG2 (to improve the state of DOM rendering in KHTML underneath a more formidable SVG 1.0 render state) and Kcanvas (to abstract any rendering done within khtml/ksvg2 in a single shared library, with multiple backends for it, e.g., Cairo/Qt, etc.).<ref>[http://mlblog.osdir.com/kde.devel.ksvg/2005-01/msg00004.shtml]{{dead link|date=March 2018|bot=InternetArchiveBot|fix-attempted=yes}}</ref>

KSVG2 is also a part of [[WebKit]].<ref>{{cite web|url=http://webkit.org/projects/svg/|title=The WebKit Open Source Project|website=Webkit.org|date=7 November 2015 |access-date=1 September 2019}}</ref>

===Sunsetting===
KHTML was scheduled to be removed in [[KDE Frameworks]] 6.<ref name="kde 6">{{cite web |url=https://phabricator.kde.org/T11543| title=Port Konqueror away from KHTML|website=phabricator.kde.org|access-date=2023-05-05}}</ref> Active development ended in 2016, just the necessary maintenance to work with updates to Frameworks 5.<ref name="git_log"/> It was officially discontinued in 2023.<ref name="discontinued"/>
