Implement a generic "load keywords and replace during runtime"
mechanism, with the first concrete use-case of WAL colors (load them
during startup, and during runtime, whenever a matching name is found in
the keywords, replace with the actual color)
To make redraw work correctly and elegantly with supplementary elements
(e.g. prefix, postfix, separators), always do a full redraw of the bar
(to make the theme update correctly, but cache the actual *data* to
display inside the output.
Add states to the modules and widgets. Widgets are mostly just a
pass-through (backwards compatibility, and ease of use - making states
directly inside the widgets would require more code inside the modules
to ensure that each widget is correctly updated).
Still missing:
- Separators during partial update (right now, it takes one interval
until separators are drawn correctly)
Add a way for themes to specify custom separators. Doing that, make
nicer interfaces for drawing "supplementary" components (separators)
for widgets and generalize the attribute retrieval within the theme.
Add two new parameters: theme and iconset
Add a placeholder class core.theme.Theme, an instance of which is passed
in to the i3 output object (which is the only object that should ever
have need of the theme, hopefully).
To make it easier to update individual modules, separate the call to
update() and the call to actually drawing the status.
Additionally, this avoids the "side effect" of updating when drawing the
status line.
To the main application, add an input thread that "simply" reads
sys.stdin events and transmits them via core.input.
Additionally, set up some initial logging (yeah, for threading, this is
needed immediately)
Add a (half-finished) input library, that for now simply allows
registration and triggering of events.
As next steps, the trigger will happen as part of a separate thread that
reads input events.
Additionally, invoking commands via a execute() will be supported.
Thirdly, there is need of a way to selectively update the affected
modules (widgets), which should be possible given that the event
contains both the instance (widget ID) and name (module name).
Parse '-p' parameters and make them accessible via 'parameter()' from
within a module (basically, restore the previous configuration
facility).
Still TODO: Add support for configuration files.
The core.output module now manages the list of modules and retrieves the
widgets inside draw() itself. That way, details of drawing/updating
widgets are not visible from the outside anymore.
Add generic "draw()" method that redirects internally to the actual
calls. These can now produce JSON, which is nicer because:
1. Easier to use during testing
2. More flexible
3. Centralizes printing (somewhat)
Still, the "suffix" concept isn't really nice, but so far, I have no
better approach.
