implement filter in unity-scopes with python

A lot of the unity-scopes do not work in ubuntu (for example the unity-scope-gmusicbrowser), thus I've tried to "correct" them in order to get results in the dash.

Ok, I succeeded in doing this (for the file: /usr/share/unity-scopes/gmusicbrowser/unity_gmusicbrowser_deamon.py: the "corrected" code: https://gist.github.com/wa4557/d6cc4ec5354bbb95042b (is it ok to post it here, even if the main part is not from me?)). This works flawlessly, and results from gmusicbrowser are now visible in the music-dash, like I want them to show up.

But I have still one small problem: How can i implement the available filters in the scopes? I think the relevant lines in the code are (line 372 ff):

def do_get_filters(self):

    '''

    Adds filters

    '''

    fs = Unity.FilterSet.new()

    #if FILTERS:

    #

    return fs

Unfortunately however there's everything commented out, and there is no serious documentation or something similar

Filters in the scope would let me to filter Music, so for example to select only Rock music etc.; I think the screenshot explains what I mean (it's german).

enter image description here

As you can see, there are no results even though I have a lot of music from the 00s in my collection...

EDIT: I have found a scope with a similar loader (unity-gdrive-scope) : https://gist.github.com/wa4557/e3a9cdef5806dc3c13c9, where the filters are added. Frankly I don't understand how this works. But there is definitely something in the do_get_filters function...

I'm trying to do something similar for the clementine scope and I think I made some progress. I modified the do_get_filters in the following way



    def do_get_filters(self):

        '''

        Adds filters

        '''

        fs = Unity.FilterSet.new()

        if FILTERS:

            fil = Unity.MultiRangeFilter.new(FILTERS[0]['id'], FILTERS[0]['name'],

                                             Gio.ThemedIcon.new(FILTERS[0]['icon']),

                                             FILTERS[0]['collapsed'])

            fs.add(fil)



            fil = Unity.RadioOptionFilter.new(FILTERS[1]['id'], FILTERS[1]['name'],

                                              Gio.ThemedIcon.new(FILTERS[1]['icon']),

                                              FILTERS[1]['collapsed'])

            fs.add(fil)

        return fs

after defining FILTERS as



f1 = {'id': 'decade',

      'name': _('Decade'),

      'icon': '',

      'collapsed': True}



f2 = {'id': 'genre',

      'name': _('Genre'),

      'icon': '',

      'collapsed': True}



FILTERS = [f1, f2]

At this point, you can do something like this in the do_run method of the MySearch class



    def do_run(self):

        '''

        Adds results to the model

        '''

        try:

            decade, genre = self.search_context.filter_state.get_filters()



            if decade.get_first_active():

                start_year = int( decade.get_first_active().get_property('id') )

            else:

                start_year = 0

            if decade.get_last_active():

                if decade.get_last_active().get_property('id') == '0':

                    end_year = 1950 + 9

                else:

                    end_year = int( decade.get_last_active().get_property('id') ) + 9

            else:

                end_year = 3000

and after that



            result_set = self.search_context.result_set

            for i in search(self.search_context.search_query,

                            self.search_context.filter_state):

                if not (start_year < i['year'].get_int32() < end_year) :

                    continue

                if not 'uri' in i or not i['uri'] or i['uri'] == '':

                    continue

                if not 'icon' in i or not i['icon'] or i['icon'] == '':

                    i['icon'] = DEFAULT_RESULT_ICON

                if not 'mimetype' in i or not i['mimetype'] or i['mimetype'] == '':

                    i['mimetype'] = DEFAULT_RESULT_MIMETYPE

                if not 'result_type' in i or not i['result_type'] or i['result_type'] == '':

                    i['result_type'] = DEFAULT_RESULT_TYPE

                if not 'category' in i or not i['category'] or i['category'] == '':

                    i['category'] = 0

                if not 'title' in i or not i['title']:

                    i['title'] = ''

                if not 'comment' in i or not i['comment']:

                    i['comment'] = ''

                if not 'dnd_uri' in i or not i['dnd_uri'] or i['dnd_uri'] == '':

                    i['dnd_uri'] = i['uri']

                i['provider_credits'] = GLib.Variant('s', PROVIDER_CREDITS)

                result_set.add_result(**i)

        except Exception as error:

            print(error)

The genre part should be similar, I have to implement it yet though.
