History

 

"Kate the Cyber Woodpecker" is the current mascot of Kate editor, designed by Tyson Tan in 2021^[6] and replacing the earlier version designed in 2014.^[7]

Kate has been part of the KDE Software Compilation since release 2.2 in 2001.^[8] Because of KParts technology, it is possible to embed Kate as an editing component in other KDE applications. Major KDE applications which use Kate as an editing component include the integrated development environment KDevelop, the web development environment Quanta Plus, and the LaTeX front-end Kile.^{[citation needed]}

Kate has won the advanced text editor comparison in Linux Voice magazine.^[9]

As of July 2014^[update], development had started to port Kate, along with Dolphin, Konsole, KDE Telepathy, and Yakuake, to KDE Frameworks 5.^[10]

In 2022, the KDE text-editor KWrite was modified to use the same code base as Kate with deactivated features.^[11]

Features

Kate is a source code editor that features syntax highlighting for over 300 file formats with code folding rules.^[12][13] The syntax highlighting is extensible via XML files.^[14] It supports UTF-8, UTF-16, ISO-8859-1 and ASCII encoding schemes and can detect a file's character encoding automatically.^{[citation needed]} Kate offers code completion and reference finding for various programming languages through its Language Server Protocol Client plugin. The default configuration supports C, C++, D, Fortran, Go, Latex, Python, Rust, and OCaml.^[15]

Kate's main text editor widget is called KatePart, which is reusable under the terms of the LGPL version 2 license.^[16] It must not be confused with the KParts, a KDE plugin framework for user interface components that Kate also uses.^[17]

Kate can be used as a modal text editor through its vi input mode.^[18]

Kate features multiple document interface, window splitting, project editing^[19] and sessions to facilitate editing multiple documents. Using sessions, one can customize Kate for different projects by saving the list of open files, the list of enabled plug-ins and the window configuration.^[20]

Kate includes the KDE terminal emulator Konsole through its Terminal Tool View plugin.^[21] As of April 2021, this feature is not available for the Windows version of Kate.^[22]

The "quick open" feature allows searching opened files by name for quick recalling.^[23] Line modification indicators highlight lines with unsaved changes and lines added in the current session.^[24][25]

Being a KDE application, Kate transparently opens and saves files over all protocols supported by KIO libraries. This includes HTTP, FTP, SSH, SMB and WebDAV, among others.^{[citation needed]}

As of September 2021^[update], unlike Xed, Kate is equipped with a session manager which allows naming, saving, and restoring sessions, meaning a list of momentarily open file tabs. Saved sessions are stored as key-value-formatted *.katesession files into ~/.local/share/kate/sessions/.

Other features are a clipboard history with up to ten items, the ability to jump to a line number,^[26] and source control integration using Git^[22]
