The Kate Application Configuration

This group contains pages to configure the main Kate application


This section contains a few global options for Kate

Switch to output view upon message type

This option allows configuring when Kate should show an output pane depending on the type of action output.

It is possible to choose between Never, Error (on error), Warning (on warning or above), Info (on info or above), and Log (on log or above).

Use a separate dialog for handling externally modified files

When enabled, Kate will notify you with a modal dialog about all files modified from outside the application whenever the main window receives input focus. You will be able to deal with several modified files at once, you can reload, save or discard changed files in groups.

If not enabled, Kate will individually ask you what to do for each modified file only when that file's view receives focus.

Quick Open
Match Mode

Set the list mode for the Quick Open tool. The files can be matched by their name or by their path.

List Mode

This section contains options related to using sessions.

Application Startup Behavior

Select how you want Kate to behave at startup. This setting can be overridden by specifying what to do on the command line.

Start new session

With this option, Kate will start a new, unnamed session when you start the application.

Load last-used session

Kate will use the most recently opened session at startup. This is good if you want to use the same session always or switch rarely.

Manually choose a session

Kate will display a small dialog that lets you choose your preferred session, or load the default session if none have been saved. This is the default behavior. Nice if you use a lot of different sessions frequently.

Application Startup/Shutdown Behavior

Select how you want Kate to behave at shutdown. It is possible to define what Kate should Automatically save and restore.

Newly-created unsaved files

With this item checked, Kate will automatically save all newly-created unsaved files.

Files with unsaved changes

This item allows configuring Kate for automatically saving all files with unsaved changes on shutdown.

Close Kate entirely when the last file is closed

If enabled, Kate will shutdown when the last file being edited is closed, otherwise a blank page will open so that you can start a new file.

Session Elements
Include window configuration

If enabled, Kate will save the window configuration with each session.

Keep meta-information past sessions

When enabled, Kate will store meta data such as bookmarks and session configuration even when you close your documents. The data will be used if the document is unchanged when reopened.

Delete unused meta-information after

Set the maximum number of days to keep meta information for previously opened files. This helps keep the database of meta information reasonably sized.

Any changes to the session data (opened files and, if enabled, window configuration) will always be saved.
