here 2 convenience methods wrote 'gkturnbasedmatch' category:

@implementation gkturnbasedmatch (convenience)  - (nsarray *) remainingplayingparticipants; {     nsmutablearray *participants = [nsmutablearray array];      // start searching @ current player     nsuinteger currentindex = [self.participants indexofobject:self.currentparticipant];      (int = 0; < [self.participants count]; i++)     {         gkturnbasedparticipant *part = [self.participants objectatindex:(currentindex + 1 + i)                                                                         % self.participants.count];         if (part.matchoutcome == gkturnbasedmatchoutcomenone)         {             [participants addobject:part];         }     }      return [nsarray arraywitharray:participants]; }   - (nsarray *) remainingplayingandmatchedopponents; {     nsmutablearray *participants = [nsmutablearray array];     gkturnbasedparticipant *localparticipant = [self localparticipant];      // start searching @ current player     nsuinteger currentindex = [self.participants indexofobject:self.currentparticipant];      (int = 0; < [self.participants count]; i++)     {         gkturnbasedparticipant *part = [self.participants objectatindex:(currentindex + 1 + i)                                         % self.participants.count];         if (part.matchoutcome == gkturnbasedmatchoutcomenone             && part.status == gkturnbasedparticipantstatusactive             && part != localparticipant)         {             [participants addobject:part];         }     }      return [nsarray arraywitharray:participants]; } @end

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
