 <para>&kappname; variables is &kappname;'s implementation of document variables, similar
 to &Emacs; and vi modelines. In katepart, the lines have the following format:
 
 <userinput>kate: VARIABLENAME VALUE; [ VARIABLENAME VALUE; ... ]</userinput>
 
 The lines can of course be in a comment, if the file is in a format with comments.
 Variable names are single words (no whitespace), and anything up to the next
 semicolon is the value. The semicolon is required.</para>
 
 <para>Here is an example variable line, forcing indentation settings for a C++,
 &Java; or &javascript; file:
 
 <programlisting>// kate: replace-tabs on; indent-width 4; indent-mode cstyle;</programlisting>
 </para>
 
 <note><para>Only the first and last 10 lines are searched for variable lines.</para></note>
 
 <para>Additionally, document variables can be placed in a file called
 <filename>.kateconfig</filename> in any directory, and the configured settings will
 be applied as if the modelines were entered on every file in the directory and its
 subdirectories. Document variables in <filename>.kateconfig</filename> use the same syntax as
 in modelines, but with <link linkend="kateconfig-extended-options">extended options</link>.</para>
 
 <para>There are variables to support almost all configurations in &kappname;, and
 additionally plugins can use variables, in which case it should be documented in
 the plugin's documentation.</para>
 
 <para>&kappname; has support for reading configurations from <filename>.editorconfig</filename>
 files, when the <ulink url="https://editorconfig.org/">editorconfig</ulink> library is installed.
 &kappname; automatically searches for a <filename>.editorconfig</filename>
 whenever you open a file. It gives priority to <filename>.kateconfig</filename> files, though.

 overwrite changes made using menu items or the command line.</para>
 
 <para>Any variable not listed below is stored in the document and can be queried

 <title>Extended Options in <filename>.kateconfig</filename> files</title>
 
 <para>&kappname; always search for a <filename>.kateconfig</filename> file for local files (not remote files).
 In addition, it is possible to set options based on wildcards (file extensions) as follows:</para>
 
 <programlisting>kate: tab-width 4; indent-width 4; replace-tabs on;
 kate-wildcard(*.xml): indent-width 2;
 kate-wildcard(Makefile): replace-tabs off;
 </programlisting>
 
 <para>In this example, all files use a tab-width of 4 spaces, an indent-width of 4 spaces,
 and tabs are replaced expanded to spaces. However, for all <filename class="extension">*.xml</filename>
 files, the indent width is set to 2 spaces.
 And Makefiles use tabs, &ie; tabs are not replaced with spaces.</para>
 
 <para>Wildcards are semicolon separated, &ie; you can also specify multiple file extensions as follows:
 </para>
 
 <programlisting>kate-wildcard(*.json;*.xml): indent-width 2;</programlisting>
 
 <para>Further, you can also use the &MIME; type to match certain files, &eg; to indent
 all C++ source files with 4 spaces, you can write:
 </para>
 
 <programlisting>kate-mimetype(text/x-c++src): indent-width 4;</programlisting>
 
 <note><para>Next to the support in <filename>.kateconfig</filename> files, wildcard and &MIME; type
 dependent document variables are also supported in the files itself as comments.
 </para></note>
