Configuring With Document Variables

KatePart variables is katepart's implementation of document variables, similar to Emacs and vi modelines. In katepart, the lines have the following format: kate: VARIABLENAME VALUE; [ VARIABLENAME VALUE; ... ] 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.

Here is an example variable line, forcing indentation settings for a C++, java or javascript file:

// kate: replace-tabs on; indent-width 4; indent-mode cstyle;

Note

Only the first and last 10 lines are searched for variable lines.

Additionally, document variables can be placed in a file called .kateconfig 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, as far down as the configured search depth. Document variables in .kateconfig use the same syntax as in modelines.

There are variables to support almost all configurations in katepart, and additionally plugins can use variables, in which case it should be documented in the plugin's documentation.

How KatePart uses Variables

When reading configuration, katepart looks in the following places (in that order):

  • The global configuration.

  • Optional session data.

  • The "Filetype" configuration.

  • Document variables in .kateconfig.

  • Document variables in the document itself.

  • Settings made during editing from menu or command line.

As you can see, document variables are only overridden by changes made at runtime. Whenever a document is saved, the document variables are reread, and will overwrite changes made using menu items or the command line.

Any variable not listed below is stored in the document and can be queried by other objects such as plugins, which can use them for their own purpose. For example, the variable indent mode uses document variables for its configuration.

The variables listed here documents KatePart version 5.38. More variables may be added in the future. There are 3 possible types of values for variables, with the following valid expressions:

  • BOOL - on|off|true|false|1|0

  • INTEGER - any integer number

  • STRING - anything else
