How to write a new theme
|
||
========================
|
||
|
||
Introduction
|
||
------------
|
||
|
||
``bumblebee-status`` themes are simply JSON files that describe various
|
||
attributes (foreground color, background color, etc.) of the blocks that
|
||
make up a status bar.
|
||
|
||
It is possible to specify each attribute at various levels:
|
||
|
||
- For a specific state of a specific module
|
||
- For a specific module
|
||
- A cycle of attributes (those are cycled through widget-by-widget)
|
||
- Default values
|
||
|
||
Looking up a value follows the “more specific rather than more generic”
|
||
approach. In other words, if a foreground color exists for the “warning”
|
||
state of module “a”, any less specific foreground color value that
|
||
**would** match will be ignored.
|
||
|
||
Themes are loaded from the following locations: -
|
||
``$(BUMBLEBEE_STATUS_BASE_DIR)/themes/`` -
|
||
``~/.config/bumblebee-status/themes/``
|
||
|
||
Basic structure
|
||
---------------
|
||
|
||
A very simple theme file looks like this:
|
||
|
||
.. code:: json
|
||
|
||
{
|
||
"icons": [ "awesome-fonts" ],
|
||
"defaults": {
|
||
"fg": "#000000",
|
||
"bg": "#ffffff",
|
||
"warning": {
|
||
"fg": "#ff0000",
|
||
"bg": "#ffffff"
|
||
}
|
||
}
|
||
}
|
||
|
||
Icons
|
||
-----
|
||
|
||
Using the ``icons`` directive, it’s possible to reuse icon definitions
|
||
for multiple themes. The value of the field is the **basename** of a
|
||
JSON file located in ``$(THEME_DIRECTORY)/icons/``. The format of the
|
||
icon file is identical to the theme itself (as the two are essentially
|
||
just merged into a single JSON.
|
||
|
||
Color definitions and pyWAL support
|
||
-----------------------------------
|
||
|
||
``bumblebee-status`` supports
|
||
`github:dylanaraps/pywal <https://github.com/dylanaraps/pywal>`__
|
||
definitions.
|
||
|
||
To make use of them, simply generate a colorset using pyWAL and
|
||
reference it in the theme like this:
|
||
|
||
.. code:: json
|
||
|
||
{
|
||
"icons": [ ],
|
||
"colors": [ "wal" ],
|
||
"defaults": {
|
||
"critical": {
|
||
"fg": "cursor",
|
||
"bg": "color5"
|
||
},
|
||
"warning": {
|
||
"fg": "cursor",
|
||
"bg": "color6"
|
||
},
|
||
}
|
||
}
|
||
|
||
Additionally, you can use the ``colors`` directive to set up named
|
||
colors for your scheme:
|
||
|
||
.. code:: json
|
||
|
||
{
|
||
"icons": [ ],
|
||
"colors": [ { "red": "#ff0000", "green": "#00ff00", "black": "#000000" } ],
|
||
"defaults": {
|
||
"critical": {
|
||
"fg": "red",
|
||
"bg": "black"
|
||
}
|
||
}
|
||
|
||
Pango support
|
||
-------------
|
||
|
||
All values that accept a full text (i.e. the base level, ``prefix`` and
|
||
``suffix``) accept a special attribute ``pango`` **instead** of all
|
||
other attributes. In other words, if you specify ``pango``, any other
|
||
attribute on that level (foreground color, etc.) will be ignored!
|
||
|
||
Inside ``pango``, you can just specify arbitrary Pango attributes, and
|
||
those will be applied to a ``<span></span>`` that’s automatically
|
||
enclosing the actual text.
|
||
|
||
