Kate’s highlighting capabilities are amazing. If you want you can highlight really complex syntax, without having to hardcode rules in C++. As an example, we’ll take a look at how Lua comments can be realized: –=] ends the multiline comment the number of ‘=’...
Read more →We have seen how scripting basically works for indentation. It’s also possible to register commandline functions (The command line is bound to F7 by default, or invoke View > Switch to Command Line). We will consider a small example again: sort the selected text. /* kate-script * name: unused * author: foo bar * license: LGPL * version: 1 * kate-version: 3.0 * functions: sorter */ function sorter (){ if (view.hasSelection()) { var start = view.startOfSelection().line; var end = view.endOfSelection().line; var text = document.textRange(start, 0, end, document.lineLength(end)); var lines = text.split(“\n”); lines.sort(); text = lines.join(“\n”); view.clearSelection(); document.editBegin(); document.removeText(start, 0, end, document.lineLength(end)); document.insertText(start, 0, text); document.editEnd(); }} The header line functions:...

(LISP indentation is easy, that’s why it’s a good example). The rules: comments starting with ;;; always have indentation 0 comments starting with ;; should be aligned with the...

How does it work? It is similar to vim: You simply create a script in the directory $KDEDIR/share/apps/katepart/jscript. An indentation script...
