I read the documentation and found this at http://freedesktop.org/wiki/Standards_2fmime_2dactions_2dspec <..skipped> The extension element associates MIME entries with application .desktop files (eg, gimp.desktop). Issues to address: 1. Must provide a way to find a command to execute to view/edit/etc a file. 2. There should be support for multiple actions (view, edit, print, etc). 3. There must be some kind of priority system (Vim can view HTML, but should not be the default if a web browser is installed). 4. Internationalised descriptions of applications should not be repeated (Gimp should not have to specify translations of "Edit in Gimp" for every MIME type it supports). The problem I was facing was mainly issue 3, coupled with other issues. TeX documents have mimetype text/x-tex which is declared as a subclass of mimetype text/plain in /usr/share/mime/packages/freedesktop.org.xml. This means that all the programs which declare that they can open text/plain document in their .desktop files placed in /usr/share/applications appears in the open with list. This is the case for all the programs I mentioned: Kate, Kwrite, Leafpad, Abiword, Screem, OpenOffice.org Writer, Emacs21, Mousepad and Gedit. So I removed text/plain from line MimeType= in the files abiword.desktop, screem.desktop and ooo645writer.desktop and ran update-desktop-database. That solved the problem of appearance of inapropriate applications in open with application list for text documents. Yet still all the remaining programs were appearing int list for tex documents, since like I've said text/x-tex is declared as a subclass of mimetype text/plain. So I removed line <sub-class-of type="text/plain"/> from text/x-tex mimetype declaration in /usr/share/mime/packages/freedesktop.org.xml and ran update-mime-database /usr/share/mime as root. This resulted in empty open with list for tex documents. So it was still the problem, since Kile should appear in this list, if it is installed. It turned out that this was Kile bug. The file kile.desktop had line [KDE Desktop Entry] instead of [Desktop Entry], and it was ignored by update-desktop-database. After fixing it and running update-desktop-database, Kile finally appeared in open with program list for text documents. So if you want that only certain applications should appear in open with list for certain document. You must make certain that: 1. The application has its .desktop file in /usr/share/applications/ and it lists the mimetype of your document in MimeType line. 2. Unwanted applications does not list the mimetype of your document in their .desktop file. 3. Your document mimetype is not a subclass of other mimetype, which is listed in unwanted applications' .desktop files. 4. You ran update-desktop-database after .desktop file change, and update-mime-database /usr/share/mime after mimetype description change. Then in open with list you will have only the appropriate applications. It is a partial solution though, since you must be root to do these changes and you must muck with application's .desktop files and mimetypes description. Your changes could probably contradict to upstream's decision. Seeing the syntax of .desktop file I think, that the issue 3 is not completely solved yet. My solution was based on text/html mimetype description. It is not subclass of text/plain, so only browsers appear in html document open with list. I filed a bug against kile. Should I file a bug against abiword, screem and OpenOffice.org? Probably not, since in the worst case scenario when for example abiword is the only program capable of editing documents, you will not see any programs in the open with list for text documents, when cleary you can use abiword for that.
