Each widget can now return a state using the method "state()". This
string is then used to look up a theme information which is used instead
of the default or module theme, if found.
see #23
Add customized separators:
* The default separators are automatically disabled if custom separators
are used (to "just" disable the default, use empty custom separators)
* Use previous background color as their background color and the
current background color as foreground color
* Allow the separator-block-width to be configured
see #23
Allow a theme to define a "cycle" of attributes that are cycled through
on a widget-per-widget basis (e.g. for alternating the widget
background). These cycles take precedence over the default values, but
can be overridden by module-specific theme instructions.
see #23
Make the format string of the datetime module configurable using the new
parameter() method in the module.
Also, restructured the setting of the config information a bit so that
the parameter() method can be used in the constructor of a module.
see #23
User can now use -p <key>=<value> to pass configuration parameters to
modules. For this, the module gets a "parameter()" method. Parameter
keys are in the format <name>.<key> where <name> is the name of the
loaded module. This is either the name of the module itself (e.g. "cpu")
or its alias, if the user specified it, for example:
bumblebee-status -m cpu -p cpu.warning=90
vs.
bumblebee-status -m cpu:test -p test.warning=90
see #23
Add an interface that allows arbitrary objects to store/retrieve
arbitrary key/value pairs. This will be used for different purposes in
the future:
* Config class(es) can store user-defined parameters for modules
* Widgets can store state
* ???
see #23
Add a helper function that lists all existing modules and modify the CPU
module test so that it now generically iterates all available modules
and tests their widgets.
see #23
Allow module-specific theme information to overload "default"
configuration. I.e. it is now possible to have specific prefix or
postfix configurations for different modules. The module name is derived
for each widget from the module (__module__) from which it was
instantiated.
see #23
Allow sub-themes ("iconsets") to be merged into the "main" theme. That
way, effectively, it's possible to define colors and icons in separate
JSON files.
see #23
Until now, widgets were re-created during each iteration. For multiple,
reasons, using static widget objects is much easier, so instead of
creating new widgets continuously, modules now create the widgets during
instantiation and get the list of widgets passed as parameter whenever
an update occurs. During the update, they can still manipulate the
widget list by removing and adding elements as needed.
Advantages:
* Less memory fragmentation (fewer (de)allocations)
* Easier event management (widgets now have static IDs)
* Easier module code (widget contents can simply be the result of a
callback)
see #23
Add custom exceptions and add error handling to the engine's module
loading logic. I.e. when a non-existent module is loaded, an exception
is thrown now.
see #23
Add basic drawing of widgets. Each module instance returns a list of
widgets using the widgets() method which is then forwarded to the draw()
method of the configured output.
see #23
Allow the user to provide aliases when loading a module multiple times
so that the modules can be differentiated (e.g. for passing parameters
to a module).
see #23
This is going to be a bit more comprehensive than anticipated. In order
to cleanly refactor the core and the engine, basically start from
scratch with the implementation.
Goals:
* Test coverage
* Maintain backwards compatibility with module interface as much as
possible (but still make modules easier to code)
* Simplicity
see #23
Cycled widget styles (such as the battery charging style) were broken
until now. The reason for this: They maintain state that represents the
current cycle position (i.e. what is the current icon that is being
displayed), but that is done in a way that uses repr() on the widget
object.
Since the widget objects are re-created each time the bar is drawn, this
is a deeply flawed design.
Instead, use the instance() of the widget for now.
Hide alias concept for modules in the engine. That way, the individual
modules never get to know about whether a module has been aliased or
not.
see #23
"nic.exclude" is now a parameter that can be used to have a custom list
of excluded interface prefixes. Multiple prefixes should be separated by
a comma.
fixes#26
When receiving a "nop" (None) command, skip it. Otherwise, an exception
is thrown and input processing stops.
Also, remove the "communicate()" call to *not* wait until a process has
finished until resuming input processing. Otherwise, whenever an
external program (pavucontrol, nautilius, ...) is started, any further
input processing is stalled until the program has been closed again.
fixes#24
Whenever the language is changed outside the bar, update the bar
accordingly. Also, when a new language is used, automatically append it
to the list of available languages.
User can now specify a list of languages as parameter (pipe-separated
list). Variants can also be specified by separating language and variant
with a :
For instance: -p layout.lang="us|rs:latin"
Left click moves on to the next language, right click to the previous.
Right now, there are the following caveats:
* The first entry in the list must be the language used when the bar
starts
* kxbd changes outside the bar are not picked up automatically
