Define the variables (colors and some other stuff) that are used when drawing the interface.
Colors are numbers from -1 to 7 (if only 8 colors are supported) or -1 to 255 if 256 colors are available. If only 8 colors are available, all colors > 8 are converted using the table_256_to_16 dict.
XHTML-IM colors are converted to -1 -> 255 colors if available, or directly to -1 -> 8 if we are in 8-color-mode.
A pair_color is a background-foreground pair. All possible pairs are not created at startup, because that would create 256*256 pairs, and almost all of them would never be used.
A theme should define color tuples, like
(200, -1), and when they are to
be used by poezio's interface, they will be created once, and kept in a list for
A color tuple is of the form
(foreground, background, optional)
A color of -1 means the default color. So if you do not want to have
a background color, use
The optional third value of the tuple defines additional information. It
is a string and can contain one or more of these characters:
(200, 208, 'bu') is bold, underlined and pink foreground on
A theme file is a python file containing one object named 'theme', which is an instance of a class (derived from the Theme class) defined in that same file. For example, in pinkytheme.py:
import theming class PinkyTheme(theming.Theme): COLOR_NORMAL_TEXT = (200, -1) theme = PinkyTheme()
if the command '/theme pinkytheme' is issued, we import the pinkytheme.py file and set the global variable 'theme' to pinkytheme.theme.
And in poezio's code we just use
Since a theme inherites from the Theme class (defined here), if a color is not defined in a theme file, the color is the default one.
Some values in that class are a list of color tuple.
[(1, -1), (2, -1), (3, -1)]
Such a list SHOULD contain at least one color tuple.
It is used for example to define color gradient, etc.
The theme class, from which all themes should inherit. All of the following values can be replaced in subclasses, in order to create a new theme.
Do not edit this file if you want to change the theme to suit your needs. Create a new theme and share it if you think it can be useful for others.
