+"""Chip viewer and widget.
+
+In the lower left corner of the main Pynche window, you will see two
+ChipWidgets, one for the selected color and one for the nearest color.  The
+selected color is the actual RGB value expressed as an X11 #COLOR name. The
+nearest color is the named color from the X11 database that is closest to the
+selected color in 3D space.  There may be other colors equally close, but the
+nearest one is the first one found.
+
+Clicking on the nearest color chip selects that named color.
+
+The ChipViewer class includes the entire lower left quandrant; i.e. both the
+selected and nearest ChipWidgets.

+"""Color Database.
+
+This file contains one class, called ColorDB, and several utility functions.
+The class must be instantiated by the get_colordb() function in this file,
+passing it a filename to read a database out of.
+
+The get_colordb() function will try to examine the file to figure out what the
+format of the file is.  If it can't figure out the file format, or it has
+trouble reading the file, None is returned.  You can pass get_colordb() an
+optional filetype argument.
+
+Supporte file types are:
+
+    X_RGB_TXT -- X Consortium rgb.txt format files.  Three columns of numbers
+                 from 0 .. 255 separated by whitespace.  Arbitrary trailing
+                 columns used as the color name.
+
+The utility functions are useful for converting between the various expected
+color formats, and for calculating other color values.

+"""DetailsViewer class.
+
+This class implements a pure input window which allows you to meticulously
+edit the current color.  You have both mouse control of the color (via the
+buttons along the bottom row), and there are keyboard bindings for each of the
+increment/decrement buttons.
+
+The top three check buttons allow you to specify which of the three color
+variations are tied together when incrementing and decrementing.  Red, green,
+and blue are self evident.  By tying together red and green, you can modify
+the yellow level of the color.  By tying together red and blue, you can modify
+the magenta level of the color.  By tying together green and blue, you can
+modify the cyan level, and by tying all three together, you can modify the
+grey level.
+
+The behavior at the boundaries (0 and 255) are defined by the `At boundary'
+option menu:
+
+    Stop
+        When the increment or decrement would send any of the tied variations
+        out of bounds, the entire delta is discarded.
+
+    Wrap Around
+        When the increment or decrement would send any of the tied variations
+        out of bounds, the out of bounds variation is wrapped around to the
+        other side.  Thus if red were at 238 and 25 were added to it, red
+        would have the value 7.
+
+    Preseve Distance
+        When the increment or decrement would send any of the tied variations
+        out of bounds, all tied variations are wrapped as one, so as to
+        preserve the distance between them.  Thus if green and blue were tied,
+        and green was at 238 while blue was at 223, and an increment of 25
+        were applied, green would be at 15 and blue would be at 0.
+
+    Squash
+        When the increment or decrement would send any of the tied variations
+        out of bounds, the out of bounds variation is set to the ceiling of
+        255 or floor of 0, as appropriate.  In this way, all tied variations
+        are squashed to one edge or the other.
+
+The following key bindings can be used as accelerators.  Note that Pynche can
+fall behind if you hold the key down as a key repeat:
+
+Left arrow == -1
+Right arrow == +1
+
+Control + Left == -10
+Control + Right == 10
+
+Shift + Left == -25
+Shift + Right == +25

+"""ListViewer class.
+
+This class implements an input/output view on the color model.  It lists every
+unique color (e.g. unique r/g/b value) found in the color database.  Each
+color is shown by small swatch and primary color name.  Some colors have
+aliases -- more than one name for the same r/g/b value.  These aliases are
+displayed in the small listbox at the bottom of the screen.
+
+Clicking on a color name or swatch selects that color and updates all other
+windows.  When a color is selected in a different viewer, the color list is
+scrolled to the selected color and it is highlighted.  If the selected color
+is an r/g/b value without a name, no scrolling occurs.
+
+You can turn off Update On Click if all you want to see is the alias for a
+given name, without selecting the color.

+"""Pynche -- The PYthon Natural Color and Hue Editor.
+
+Contact: %(AUTHNAME)s
+Email:   %(AUTHEMAIL)s
+Version: %(__version__)s
+
+Pynche is based largely on a similar color editor I wrote years ago for the
+SunView window system.  That editor was called ICE: the Interactive Color
+Editor.  I'd always wanted to port the editor to X but didn't feel like
+hacking X and C code to do it.  Fast forward many years, to where Python +
+Tkinter provides such a nice programming environment, with enough power, that
+I finally buckled down and implemented it.  I changed the name because these
+days, 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

+Pynche - The PYthonically Natural Color and Hue Editor
+
+Contact: Barry A. Warsaw
+Email:   bwarsaw@python.org
+Version: 1.3
+
+Introduction
+
+    Pynche is a color editor based largely on a similar program that I
+    originally wrote back in 1987 for the Sunview window system.  That
+    editor was called ICE, the Interactive Color Editor.  I'd always
+    wanted to port this program to X but didn't feel like hacking X
+    and C code to do it.  Fast forward many years, to where Python +
+    Tkinter provides such a nice programming environment, with enough
+    power, that I finally buckled down and re-implemented it.  I
+    changed the name because these days, too many other systems have
+    the acronym `ICE'.
+
+    Pynche should work with any variant of Python after 1.5.2
+    (e.g. 2.0.1 and 2.1.1), using Tk 8.0.x.  It's been tested on
+    Solaris 2.6, Windows NT 4, and various Linux distros.  You'll want
+    to be sure to have at least Tk 8.0.3 for Windows.  Also, Pynche is
+    very colormap intensive, so it doesn't work very well on 8-bit
+    graphics cards; 24bit+ graphics cards are so cheap these days,
+    I'll probably never "fix" that.
+
+    Pynche must find a text database of colors names in order to
+    provide `nearest' color matching.  Pynche is distributed with an
+    rgb.txt file from the X11R6.4 distribution for this reason, along
+    with other "Web related" database (see below).  You can use a
+    different file with the -d option.  The file xlicense.txt contains
+    the license only for rgb.txt and both files are in the X/
+    subdirectory.
+
+    Pynche is pronounced: Pin'-chee
+
+
+Running Standalone
+
+    On Unix, start it by running the `pynche' script.  On Windows, run
+    pynche.pyw to inhibit the console window.  When run from the
+    command line, the following options are recognized:
+
+    --database file
+    -d file
+        Alternate location of the color database file.  Without this
+        option, the first valid file found will be used (see below).
+
+    --initfile file
+    -i file
+        Alternate location of the persistent initialization file.  See 
+        the section on Persistency below.
+
+    --ignore
+    -X
+        Ignore the persistent initialization file when starting up.
+        Pynche will still write the current option settings to the
+        persistent init file when it quits.
+
+    --help
+    -h
+        Print the help message.
+
+    initialcolor
+        a Tk color name or #rrggbb color spec to be used as the
+        initially selected color.  This overrides any color saved in
+        the persistent init file.  Since `#' needs to be escaped in
+        many shells, it is optional in the spec (e.g. #45dd1f is the
+        same as 45dd1f).
+
+
+Running as a Modal Dialog
+
+    Pynche can be run as a modal dialog, inside another application,
+    say as a general color chooser.  In fact, Grail 0.6 uses Pynche
+    and a future version of IDLE may as well.  Pynche supports the API
+    implemented by the Tkinter standard tkColorChooser module, with a
+    few changes as described below.  By importing pyColorChooser from
+    the Pynche package, you can run
+
+        pyColorChooser.askcolor()
+
+    which will popup Pynche as a modal dialog, and return the selected 
+    color.
+
+    There are some UI differences when running as a modal
+    vs. standalone.  When running as a modal, there is no "Quit" menu
+    item under the "File" menu.  Instead there are "Okay" and "Cancel"
+    buttons.
+
+    When "Okay" is hit, askcolor() returns the tuple
+
+        ((r, g, b), "name")
+
+    where r, g, and b are red, green, and blue color values
+    respectively (in the range 0 to 255).  "name" will be a color name
+    from the color database if there is an exact match, otherwise it
+    will be an X11 color spec of the form "#rrggbb".  Note that this
+    is different than tkColorChooser, which doesn't know anything
+    about color names.
+
+    askcolor() supports the following optional keyword arguments:
+
+        color
+            the color to set as the initial selected color
+
+        master[*]
+            the master window to use as the parent of the modal
+            dialog.  Without this argument, pyColorChooser will create 
+            its own Tkinter.Tk instance as the master.  This may not
+            be what you want.
+
+        databasefile
+            similar to the --database option, the value must be a
+            file name
+
+        initfile[*]
+            similar to the --initfile option, the value must be a
+            file name
+
+        ignore[*]
+            similar to the --ignore flag, the value is a boolean
+
+        wantspec
+            When this is true, the "name" field in the return tuple
+            will always be a color spec of the form "#rrggbb".  It
+            will not return a color name even if there is a match;
+            this is so pyColorChooser can exactly match the API of
+            tkColorChooser.
+
+        [*] these arguments must be specified the first time
+        askcolor() is used and cannot be changed on subsequent calls.
+
+
+The Colorstrip Window
+
+    The top part of the main Pynche window contains the "variation
+    strips".  Each strip contains a number of "color chips".  The
+    strips always indicate the currently selected color by a highlight
+    rectangle around the selected color chip, with an arrow pointing
+    to the chip.  Each arrow has an associated number giving you the
+    color value along the variation's axis.  Each variation strip
+    shows you the colors that are reachable from the selected color by
+    varying just one axis of the color solid.
+
+    For example, when the selected color is (in Red/Green/Blue
+    notation) 127/127/127, the Red Variations strip shows you every
+    color in the range 0/127/127 to 255/127/127.  Similarly for the
+    green and blue axes.  You can select any color by clicking on its
+    chip.  This will update the highlight rectangle and the arrow, as
+    well as other displays in Pynche.
+
+    Click on "Update while dragging" if you want Pynche to update the
+    selected color while you drag along any variation strip (this will
+    be a bit slower).  Click on "Hexadecimal" to display the arrow
+    numbers in hex.
+
+    There are also two shortcut buttons in this window, which
+    auto-select Black (0/0/0) and White (255/255/255).
+
+
+The Proof Window
+
+    In the lower left corner of the main window you see two larger
+    color chips.  The Selected chip shows you a larger version of the
+    color selected in the variation strips, along with its X11 color
+    specification.  The Nearest chip shows you the closest color in
+    the X11 database to the selected color, giving its X11 color
+    specification, and below that, its X11 color name.  When the
+    Selected chip color exactly matches the Nearest chip color, you
+    will see the color name appear below the color specification for
+    the Selected chip.
+    
+    Clicking on the Nearest color chip selects that color.  Color
+    distance is calculated in the 3D space of the RGB color solid and
+    if more than one color name is the same distance from the selected
+    color, the first one found will be chosen.
+
+    Note that there may be more than one X11 color name for the same
+    RGB value.  In that case, the first one found in the text database
+    is designated the "primary" name, and this is shown under the
+    Nearest chip.  The other names are "aliases" and they are visible
+    in the Color List Window (see below).
+
+    Both the color specifications and color names are selectable for
+    copying and pasting into another window.
+
+
+The Type-in Window
+
+    At the lower right of the main window are three entry fields.
+    Here you can type numeric values for any of the three color axes.
+    Legal values are between 0 and 255, and these fields do not allow
+    you to enter illegal values.  You must hit Enter or Tab to select
+    the new color.
+
+    Click on "Update while typing" if you want Pynche to select the
+    color on every keystroke (well, every one that produces a legal
+    value!)  Click on "Hexadecimal" to display and enter color values
+    in hex.
+
+
+Other Views
+
+    There are three secondary windows which are not displayed by
+    default.  You can bring these up via the "View" menu on the main
+    Pynche window.
+
+
+The Text Window
+
+    The "Text Window" allows you to see what effects various colors
+    have on the standard Tk text widget elements.  In the upper part
+    of the window is a plain Tk text widget and here you can edit the
+    text, select a region of text, etc.  Below this is a button "Track
+    color changes".  When this is turned on, any colors selected in
+    the other windows will change the text widget element specified in
+    the radio buttons below.  When this is turned off, text widget
+    elements are not affected by color selection.
+
+    You can choose which element gets changed by color selection by
+    clicking on one of the radio buttons in the bottom part of this
+    window.  Text foreground and background affect the text in the
+    upper part of the window.  Selection foreground and background
+    affect the colors of the primary selection which is what you see
+    when you click the middle button (depending on window system) and
+    drag it through some text.
+
+    The Insertion is the insertion cursor in the text window, where
+    new text will be inserted as you type.  The insertion cursor only
+    has a background.
+
+
+The Color List Window
+
+    The "Color List" window shows every named color in the color name
+    database (this window may take a while to come up).  In the upper
+    part of the window you see a scrolling list of all the color names
+    in the database, in alphabetical order.  Click on any color to
+    select it.  In the bottom part of the window is displayed any
+    aliases for the selected color (those color names that have the
+    same RGB value, but were found later in the text database).  For
+    example, find the color "Black" and you'll see that its aliases
+    are "gray0" and "grey0".
+
+    If the color has no aliases you'll see "<no aliases>" here.  If you
+    just want to see if a color has an alias, and do not want to select a
+    color when you click on it, turn off "Update on Click".
+
+    Note that the color list is always updated when a color is selected
+    from the main window.  There's no way to turn this feature off.  If
+    the selected color has no matching color name you'll see
+    "<no matching color>" in the Aliases window.
+
+
+The Details Window
+
+    The "Details" window gives you more control over color selection
+    than just clicking on a color chip in the main window.  The row of
+    buttons along the top apply the specified increment and decrement
+    amounts to the selected color.  These delta amounts are applied to
+    the variation strips specified by the check boxes labeled "Move
+    Sliders".  Thus if just Red and Green are selected, hitting -10
+    will subtract 10 from the color value along the red and green
+    variation only.  Note the message under the checkboxes; this
+    indicates the primary color level being changed when more than one
+    slider is tied together.  For example, if Red and Green are
+    selected, you will be changing the Yellow level of the selected
+    color.
+
+    The "At Boundary" behavior determines what happens when any color
+    variation hits either the lower or upper boundaries (0 or 255) as
+    a result of clicking on the top row buttons:
+
+    Stop
+        When the increment or decrement would send any of the tied
+        variations out of bounds, the entire delta is discarded.
+
+    Wrap Around
+        When the increment or decrement would send any of the tied
+        variations out of bounds, the out of bounds value is wrapped
+        around to the other side.  Thus if red were at 238 and +25
+        were clicked, red would have the value 7.
+
+    Preserve Distance
+        When the increment or decrement would send any of the tied
+        variations out of bounds, all tied variations are wrapped as
+        one, so as to preserve the distance between them.  Thus if
+        green and blue were tied, and green was at 238 while blue was
+        at 223, and +25 were clicked, green would be at 15 and blue
+        would be at 0.
+
+    Squash
+        When the increment or decrement would send any of the tied
+        variations out of bounds, the out of bounds variation is set
+        to the ceiling of 255 or floor of 0, as appropriate.  In this
+        way, all tied variations are squashed to one edge or the
+        other.
+
+    The top row buttons have the following keyboard accelerators:
+
+    -25 == Shift Left Arrow
+    -10 == Control Left Arrow
+     -1 == Left Arrow
+     +1 == Right Arrow
+    +10 == Control Right Arrow
+    +25 == Shift Right Arrow
+
+
+Keyboard Accelerators
+
+    Alt-w in any secondary window dismisses the window.  In the main
+    window it exits Pynche (except when running as a modal).
+
+    Alt-q in any window exits Pynche (except when running as a modal).
+
+
+Persistency
+
+    Pynche remembers various settings of options and colors between
+    invocations, storing these values in a `persistent initialization
+    file'.  The actual location of this file is specified by the
+    --initfile option (see above), and defaults to ~/.pynche.
+
+    When Pynche exits, it saves these values in the init file, and
+    re-reads them when it starts up.  There is no locking on this
+    file, so if you run multiple instances of Pynche at a time, you
+    may clobber the init file.
+
+    The actual options stored include
+
+    - the currently selected color
+
+    - all settings of checkbox and radio button options in all windows
+
+    - the contents of the text window, the current text selection and
+      insertion point, and all current text widget element color
+      settings.
+
+    - the name of the color database file (but not its contents)
+
+    You can inhibit Pynche from reading the init file by supplying the
+    --ignore option on the command line.  However, you cannot suppress
+    the storing of the settings in the init file on Pynche exit.  If
+    you really want to do this, use /dev/null as the init file, using
+    --initfile.
+
+
+Color Name Database Files
+
+    Pynche uses a color name database file to calculate the nearest
+    color to the selected color, and to display in the Color List
+    view.  Several files are distributed with Pynche, described
+    below.  By default, the X11 color name database file is selected.
+    Other files:
+
+    html40colors.txt -- the HTML 4.0 guaranteed color names
+
+    websafe.txt -- the 216 "Web-safe" colors that Netscape and MSIE
+    guarantee will not be dithered.  These are specified in #rrggbb
+    format for both values and names
+
+    webcolors.txt -- The 140 color names that Tim Peters and his
+    sister say NS and MSIE both understand (with some controversy over 
+    AliceBlue).
+
+    namedcolors.txt -- an alternative set of Netscape colors.
+
+    You can switch between files by choosing "Load palette..." from
+    the "File" menu.  This brings up a standard Tk file dialog.
+    Choose the file you want and then click "Ok".  If Pynche
+    understands the format in this file, it will load the database and 
+    update the appropriate windows.  If not, it will bring up an error 
+    dialog.
+
+
+To Do
+
+    Here's a brief list of things I want to do (some mythical day):
+
+    - Better support for resizing the top level windows
+
+    - More output views, e.g. color solids
+
+    - Have the notion of a `last color selected'; this may require a
+      new output view
+
+    - Support setting the font in the text view
+
+    - Support distutils setup.py for installation
+
+    I'm open to suggestions!

+"""Strip viewer and related widgets.
+
+The classes in this file implement the StripViewer shown in the top two thirds
+of the main Pynche window.  It consists of three StripWidgets which display
+the variations in red, green, and blue respectively of the currently selected
+r/g/b color value.
+
+Each StripWidget shows the color variations that are reachable by varying an
+axis of the currently selected color.  So for example, if the color is
+
+  (R,G,B)=(127,163,196)
+
+then the Red variations show colors from (0,163,196) to (255,163,196), the
+Green variations show colors from (127,0,196) to (127,255,196), and the Blue
+variations show colors from (127,163,0) to (127,163,255).
+
+The selected color is always visible in all three StripWidgets, and in fact
+each StripWidget highlights the selected color, and has an arrow pointing to
+the selected chip, which includes the value along that particular axis.
+
+Clicking on any chip in any StripWidget selects that color, and updates all
+arrows and other windows.  By toggling on Update while dragging, Pynche will
+select the color under the cursor while you drag it, but be forewarned that
+this can be slow.

+"""Switchboard class.
+
+This class is used to coordinate updates among all Viewers.  Every Viewer must
+conform to the following interface:
+
+    - it must include a method called update_yourself() which takes three
+      arguments; the red, green, and blue values of the selected color.
+
+    - When a Viewer selects a color and wishes to update all other Views, it
+      should call update_views() on the Switchboard object.  Note that the
+      Viewer typically does *not* update itself before calling update_views(),
+      since this would cause it to get updated twice.
+
+Optionally, Viewers can also implement:
+
+    - save_options() which takes an optiondb (a dictionary).  Store into this
+      dictionary any values the Viewer wants to save in the persistent
+      ~/.pynche file.  This dictionary is saved using marshal.  The namespace
+      for the keys is ad-hoc; make sure you don't clobber some other Viewer's
+      keys!
+
+    - withdraw() which takes no arguments.  This is called when Pynche is
+      unmapped.  All Viewers should implement this.
+
+    - colordb_changed() which takes a single argument, an instance of
+      ColorDB.  This is called whenever the color name database is changed and
+      gives a chance for the Viewers to do something on those events.  See
+      ListViewer for details.
+
+External Viewers are found dynamically.  Viewer modules should have names such
+as FooViewer.py.  If such a named module has a module global variable called
+ADDTOVIEW and this variable is true, the Viewer will be added dynamically to
+the `View' menu.  ADDTOVIEW contains a string which is used as the menu item
+to display the Viewer (one kludge: if the string contains a `%', this is used
+to indicate that the next character will get an underline in the menu,
+otherwise the first character is underlined).
+
+FooViewer.py should contain a class called FooViewer, and its constructor
+should take two arguments, an instance of Switchboard, and optionally a Tk
+master window.

+"""TextViewer class.
+
+The TextViewer allows you to see how the selected color would affect various
+characteristics of a Tk text widget.  This is an output viewer only.
+
+In the top part of the window is a standard text widget with some sample text
+in it.  You are free to edit this text in any way you want (BAW: allow you to
+change font characteristics).  If you want changes in other viewers to update
+text characteristics, turn on Track color changes.
+
+To select which characteristic tracks the change, select one of the radio
+buttons in the window below.  Text foreground and background affect the text
+in the window above.  The Selection is what you see when you click the middle
+button and drag it through some text.  The Insertion is the insertion cursor
+in the text window (which only has a background).

+"""TypeinViewer class.
+
+The TypeinViewer is what you see at the lower right of the main Pynche
+widget.  It contains three text entry fields, one each for red, green, blue.
+Input into these windows is highly constrained; it only allows you to enter
+values that are legal for a color axis.  This usually means 0-255 for decimal
+input and 0x0 - 0xff for hex input.
+
+You can toggle whether you want to view and input the values in either decimal
+or hex by clicking on Hexadecimal.  By clicking on Update while typing, the
+color selection will be made on every change to the text field.  Otherwise,
+you must hit Return or Tab to select the color.
