Clawsker - A Claws Mail Tweaker

Clawsker is an applet to edit the so called Claws Mail hidden preferences.

Claws Mail is a fast, lightweight and feature-rich MUA with a high number of configurable options. To keep the binary small and fast some of these preferences which are not widely used are not provided with a graphical interface for inspection and/or modification.

Users wanting to edit such preferences had to face raw editing of their configuration files, now you can do it with a convenient GTK interface using Clawsker.

In adition to hidden features Clawsker can edit also some other settings which usually can only be set indirectly. These include currently the saved positions (and sizes when available) of Claws Mail windows.


-a | --alternate-config-dir dirname
Uses dirname as Claws Mail configuration directory.
-b | --verbose
Tells more on the standard output.
-c | --clawsrc filename
Uses filename as Claws Mail resource configuration file. This sets the full file name overriding any previous setting.
-h | --help
Shows a brief help screen.
-r | --read-only
Edits hidden preferences without saving the changes. It also works while Claws Mail is running.
-v | --version
Shows version information for program, Perl-GTK and Claws Mail.

Weird option specifications may produce weird results (but otherwise correct).


A running Claws Mail cannot be detected if using the --clawsrc option because the directory is not assumed to be a Claws Mail configuration dir. If that is the case use the --alternate-config-dir option instead.

Detection will also fail if the temporary directory resolution differs. This may happen, for example, when the value of the environment variable TMPDIR under Clawsker is not the same that it was when Claws Mail was launched.
