"""Pynche -- The PYthon Natural Color and Hue Editor. Contact: %(AUTHNAME)sEmail:   %(AUTHEMAIL)sVersion: %(__version__)s Pynche is based largely on a similar color editor I wrote years ago for theSunView window system.  That editor was called ICE: the Interactive ColorEditor.  I'd always wanted to port the editor to X but didn't feel likehacking X and C code to do it.  Fast forward many years, to where Python +Tkinter provides such a nice programming environment, with enough power, thatI finally buckled down and implemented it.  I changed the name because thesedays, too many other systems have the acronym `ICE'. This program currently requires Python 2.2 with Tkinter. Usage: %(PROGRAM)s [-d file] [-i file] [-X] [-v] [-h] [initialcolor] Where:    --database file    -d file        Alternate location of a color database file     --initfile file    -i file        Alternate location of the initialization file.  This file contains a        persistent database of the current Pynche options and color.  This        means that Pynche restores its option settings and current color when        it restarts, using this file (unless the -X option is used).  The        default is ~/.pynche     --ignore    -X        Ignore the initialization file when starting up.  Pynche will still        write the current option settings to this file when it quits.     --version    -v        print the version number and exit     --help    -h        print this message     initialcolor        initial color, as a color name or #RRGGBB format""" __version__ = '1.4.1' import sysimport osimport getoptimport ColorDB from PyncheWidget import PyncheWidgetfrom Switchboard import Switchboardfrom StripViewer import StripViewerfrom ChipViewer import ChipViewerfrom TypeinViewer import TypeinViewer  PROGRAM = sys.argv[0]AUTHNAME = 'Barry Warsaw'AUTHEMAIL = 'barry@python.org' # Default locations of rgb.txt or other textual color databaseRGB_TXT = [    # Solaris OpenWindows    '/usr/openwin/lib/rgb.txt',    # Linux    '/usr/lib/X11/rgb.txt',    # The X11R6.4 rgb.txt file    os.path.join(sys.path[0], 'X/rgb.txt'),    # add more here    ]  # Do this because PyncheWidget.py wants to get at the interpolated docstring# too, for its Help menu.def docstring():    return __doc__ % globals()  def usage(code, msg=''):    print docstring()    if msg:        print msg    sys.exit(code)  def initial_color(s, colordb):    # function called on every color    def scan_color(s, colordb=colordb):        try:            r, g, b = colordb.find_byname(s)        except ColorDB.BadColor:            try:                r, g, b = ColorDB.rrggbb_to_triplet(s)            except ColorDB.BadColor:                return None, None, None        return r, g, b    #    # First try the passed in color    r, g, b = scan_color(s)    if r is None:        # try the same color with '#' prepended, since some shells require        # this to be escaped, which is a pain        r, g, b = scan_color('#' + s)    if r is None:        print 'Bad initial color, using gray50:', s        r, g, b = scan_color('gray50')    if r is None:        usage(1, 'Cannot find an initial color to use')        # does not return    return r, g, b  def build(master=None, initialcolor=None, initfile=None, ignore=None,          dbfile=None):    # create all output widgets    s = Switchboard(not ignore and initfile)    # defer to the command line chosen color database, falling back to the one    # in the .pynche file.    if dbfile is None:        dbfile = s.optiondb().get('DBFILE')    # find a parseable color database    colordb = None    files = RGB_TXT[:]    if dbfile is None:        dbfile = files.pop()    while colordb is None:        try:            colordb = ColorDB.get_colordb(dbfile)        except (KeyError, IOError):            pass        if colordb is None:            if not files:                break            dbfile = files.pop(0)    if not colordb:        usage(1, 'No color database file found, see the -d option.')    s.set_colordb(colordb)     # create the application window decorations    app = PyncheWidget(__version__, s, master=master)    w = app.window()     # these built-in viewers live inside the main Pynche window    s.add_view(StripViewer(s, w))    s.add_view(ChipViewer(s, w))    s.add_view(TypeinViewer(s, w))     # get the initial color as components and set the color on all views.  if    # there was no initial color given on the command line, use the one that's    # stored in the option database    if initialcolor is None:        optiondb = s.optiondb()        red = optiondb.get('RED')        green = optiondb.get('GREEN')        blue = optiondb.get('BLUE')        # but if there wasn't any stored in the database, use grey50        if red is None or blue is None or green is None:            red, green, blue = initial_color('grey50', colordb)    else:        red, green, blue = initial_color(initialcolor, colordb)    s.update_views(red, green, blue)    return app, s  def run(app, s):    try:        app.start()    except KeyboardInterrupt:        pass  def main():    try:        opts, args = getopt.getopt(            sys.argv[1:],            'hd:i:Xv',            ['database=', 'initfile=', 'ignore', 'help', 'version'])    except getopt.error, msg:        usage(1, msg)     if len(args) == 0:        initialcolor = None    elif len(args) == 1:        initialcolor = args[0]    else:        usage(1)     ignore = False    dbfile = None    initfile = os.path.expanduser('~/.pynche')    for opt, arg in opts:        if opt in ('-h', '--help'):            usage(0)        elif opt in ('-v', '--version'):            print """\Pynche -- The PYthon Natural Color and Hue Editor.Contact: %(AUTHNAME)sEmail:   %(AUTHEMAIL)sVersion: %(__version__)s""" % globals()            sys.exit(0)        elif opt in ('-d', '--database'):            dbfile = arg        elif opt in ('-X', '--ignore'):            ignore = True        elif opt in ('-i', '--initfile'):            initfile = arg     app, sb = build(initialcolor=initialcolor,                    initfile=initfile,                    ignore=ignore,                    dbfile=dbfile)    run(app, sb)    sb.save_views()  if __name__ == '__main__':    main()
