Zim does not correctly check if dependencies for plugins are met

[Viale Fabrice]

When you go to edition/preference/plugin (I have a french version, not sure of the names), you can select or unselect all plugins except the link map plugin (carte des liens).

GraphViz was not installed. But the diagram plugin can be selected - unselected while it also requires GraphViz.

sorry, version is 0.42

Looks to me that correct behavior would be to not allow selecting plugins when requirements are not met. Default plugins should be disabled when requirements are not satisfied.

[Viale Fabrice (viale-fabrice)]

I agree.

I see the same behavior in 0.43 installed yesterday (01/29/2010) from Debian Squeeze repository. All plugins (except for Link Map) can be selected or unselected, regardless of whether or not the requirements for other packages are satisfied. Once I selected LInk Map I found that it cannot be unselected.

Will use this ticket as a more general item for how zim deals with plugin dependencies. Updated title to reflect that. Of course the issue with the Link Map plugin should be fixed under this cover.

See bug #515752 for another example

The original problem with the linkmap plugin should be fixed in rev 209.

Generic patch for checking all dependencies when a plugin is loaded as well as in the preferences dialog merged in rev211.
