"""
|
|
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
|
|
later usage.
|
|
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 ``(x, -1)``.
|
|
The optional third value of the tuple defines additional information. It
|
|
is a string and can contain one or more of these characters:
|
|
|
|
- ``b``: bold
|
|
- ``u``: underlined
|
|
- ``x``: blink
|
|
|
|
For example, ``(200, 208, 'bu')`` is bold, underlined and pink foreground on
|
|
orange background.
|
|
|
|
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:
|
|
|
|
.. code-block:: python
|
|
|
|
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 ``theme.COLOR_NORMAL_TEXT`` etc
|
|
|
|
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.
|
|
For example ``[(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.
