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 and all hot key mappings from application menus.


-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.

-i | --ignore-versions

Ignores any version detected or set by -u option. Almost all options will be available.

-k | --hide-disabled-keys

On hotkeys columns sets foreground colour of unassigned keys to the same colour used as background, rendering them invisible until selected. This may help locating assigned keys on very long lists.

-r | --read-only

Edits hidden preferences without saving the changes. It also works while Claws Mail is running.

-s | --small-screen

Resolution of display is autodetected to adjust UI for screens where default rendering would exceed available space. This option forces those small screen adjustments. This can be useful for screens where the UI fits resolution, but the screen state is already used by other programs.

-u | --use-claws-version version

Uses version as Claws Mail version instead of the real one. The version argument is a list of integers, separated by dots if needed.

-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 when using the --clawsrc option because the directory containing the given file is not expected to be a full Claws Mail configuration folder. 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. For Claws Mail versions greater than 3.17.8 different values for XDG_RUNTIME_DIR or XDG_CACHE_HOME may also cause this.


You can send bug reports using the Claws Mail bugzilla instance located at <http://www.thewildbeast.co.uk/claws-mail/bugzilla/>. When creating the bug please select the clawsker product.

Security bugs can be reported also in bugzilla or to the main author directly if a coordinated disclosure is preferable.
