 Posted: Tue Jul 01, 2008 9:43 am Post subject: eselect flash-nsplugin |
 |
|
I'm actually a bit unsure where this should go, but as it contains a programming-related question I just post it here. I wrote an eselect module to switch between different Flash Mozilla Plugins (see below). It seems to work quite well, at least for me on Multilib Profile, but there is one problem: since most Flash plugins install directly to the nsbrowser/plugins directory, I had to keep the actual library files somewhere else, so that only one plugin is loaded at a time. So I will have to move all files from their install locations to that path for every update - is there a preferred way of handling this? So far I thought of two solutions: (1) have an ebuild DEPEND on all Flash implementations, and move them accordingly, so that re-moving updated files will presumably be handled by revdep-rebuild, or (2) modifying the flash ebuilds so that they install to another directory, similar to the way it is done with mailwrapper. As an additional problem, I used /usr/share/eselect-flash as base directory for the storage of the plugins which seems a bit arbitrary. I wondered if there would be a better location for the libraries, maybe /usr/lib ?
This is the module, based on java-nsplugin.eselect:

Hi,
I didn't test this module but I was in bad need of such a module while I used seamonkey-1.1.x as my preferred webbrowser.
Usually such stuff, that could extend Gentoo, belongs to https://bugs.gentoo.org/ but I'm not sure wether the devs are interested in such a module. Firefox-3 and seamonkey-2 both can en-/disable plugins seperately in their addon managers so this eselect-module could loose it usefulness, once firefox-3/seamonkey-2 become stable in Gentoo (don't misunderstand, seamonkey-2 wasn't even released yet and is still in pre-alpha state).
Cheers
Poly-C
