Kate Project Plugin

It is not a secret that removing Kate’s project manager in KDE 3.5 was not the right thing to do. It seems a lot of people used it and we got many complaints about this decision. That also shows that it is hard go get feedback about what users are really using. If a feature is done well, noone will ever talk about it. This is paradox, as we thought the project manager was not well integrated :) (I still think that)

Triple clicks

Text editors and line edits support the so-called triple clicks according to [1]1. The document says Triple Click: Select the targeted row. […] It is unclear whether the “targeted row” includes the trailing linebreak. Kate Part selects the targeted line including the linebreak. You get the following behavior: If you move the selected row with the mouse, you usually have the linebreaks right. The same applies for copy/cut & paste.

Kate Modes & Filetypes

Modes allow the user to override the default configuration for documents of specified mimetypes or file extensions. When the editor loads a document and the mimetype or file extensions match for one of the defined filetypes, KatePart will read the configuration from the mode and apply the modelines defined. If more filetypes match, the one with the highest priority will be used. To create a filetype, go into the settings dialog available in Kate via Settings > Configure Kate > Open/Save > Modes/Filetypes, then press the New button and fill in the properties.

.kateconfig Files

Kate allows you to specify local document variables by setting the corresponding modelines. The hidden file .kateconfig provides exactly the same functionality, but for all files in the directory. Enable the Feature To use a .kateconfig file you first have to enable the feature by invoking Settings > Configure Kate. In the config page Open/Save you can find the option Search depth for config file, which defaults to Do not use a config file.

Kate Modelines

Kate Part’s modelines – also called Kate document variables – are Kate Part’s implementation of document variables, similar to Emacs and vim modelines. Document variables can be used to set Kate settings local to a file. This is for example for using another indenter than the one defined in the GUI settings. Or assume you work on two projects, the first indents with spaces and the second with tabs, then you can simply add a modeline that contains the specific document variables that set the specific indentation properties.

Writing a Syntax Highlighting File

Note: Please refer to the Kate Handbook for the most recent version of how to write syntax highlighting files. Hint: If you want to write a syntax highlighting file, the XML Completion plugin might be of great help. This section is an overview of the Highlight Definition XML format in KDE4. Based on a small example it will describe the main components and their meaning and usage. The next section will go into detail with the highlight detection rules.

Writing a Kate Plugin

Introduction First at all, why writing plugins for an editor ? Good question, and I hope I have a good answer: Because we want Kate to be small and all extended features not all users need should go into plugins (like CVS suppport, project managment, coffee cooking ;) Therefore Kate provides a quite full-featured plugin interface and interfaces to all important stuff in the Kate application (the documents, views, windows, sidebar …).
