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
This one is a bit tricky:
* Clicking on an active xrandr output will disable it
* Clicking on a disabled xrandr output will enable it -> if
it is a left-click, it will put it as the left-most display
if it is a right-click, as the right-most display
Also, it will reload the i3 bars (using a script that allows
you to write custom pieces of an i3 configuration that is applied
conditionally depending on the screens you have).
It goes like this:
* Base config is in ~/.i3/config.template
* Output-specific config is in ~/.i3/config.<screen name>
* Output-specific config when other screens are also active is in
~/.i3/config.<screen>-<other-screens-in-alphabetic-order>
For instance:
$ ls ~/.i3
config.template
config.eDP1 -> will be applied to eDP1 (always)
config.VGA1-eDP1 -> will be applied to VGA1, if eDP1 is also active
config.VGA1 -> will be applied to VGA1 (if eDP1 is inactive)
fixes#19
This modules shows attached displays and their states (on or off).
Future versions of this module will order the icons by the relative
order of the screens (left-to-right) and will allow switching monitors
on and off.
see #19
Add code that allows themes to be merged (i.e. if certain elements are
not present in a theme, another theme can be "overlaid" to add missing
elements).
Effectively, this is used to create the logical concept of an "icon
theme", which is loaded after the main theme. So, the main theme can
define colors, and the icon theme fills in any missing elements
(practically, all the icons in the form of prefixes and suffixes).
Icon sets are defined in a theme using the "icons" directive, which
should be an array.
