If a module defines a callback for a widget's text, an optional
decorator "@bumblebee.output.scrollable" can be used to make the text
scrollable.
In those cases, the desired width is set to (in decreasing order of
priority):
1. whatever the widget defines as "theme.width"
2. whatever the theme defines as "width" for the module
3. whatever the commandline parameter "width" for the module is set to
4. 30 (determined by unfair dice roll)
see #27
Added theme-options ("minwidth" and "align") for setting the minimum
width and the alignment of a widget.
Also, allow widget to provide defaults for the theme options by setting
an attribute in their store called "theme-<name of the theme option>".
For example, a widget can now define a default alignment by using:
widget.set("theme-align", "default-value").
* If an exception is thrown, catch it and show a (somewhat) nice error
message in the i3bar instead of the normal content
* Add a flag "-d" for debugging into a debug log. Currently, this only
logs commandline calls as they occur and their return values, as well
as exceptions.
fixes#58
Show RTT measured by ICMP echo request/replies for a given host.
For that to work correctly, change the "full_text" callback for a widget
so that the widget itself is also passed as argument in the callback
method. That actually makes a lot of sense, since the widget can now be
used as a repository of state information.
see #23
Re-add the NIC module with all its functionality (hopefully...).
This introduces a new concept: Instead of having separate queries for
critical and warning (which really are just another set of states), a
module can now return a list of states for each widget. All the state
information is then merged together into a single theme. So, for
instance, the NIC module can return a state saying "critical -
wlan-down", which applies the theme information for both "critical" and
"wlan-down".
see #23
The cpu module now has cpu.warning and cpu.critical thresholds. If the
CPU utilization is higher than any of those values, the widget's state
changes to warning or critical, respectively.
see #23
Create infrastructure for input event handling and add i3bar event
processing. For each event, callbacks can be registered in the input
module.
Modules and widgets both identify themselves using a unique ID (the
module name for modules, a generated UUID for the widgets). This ID is
then used for registering the callbacks. This is possible since both
widgets and modules are statically allocated & do not change their IDs.
Callback actions can be either callable Python objects (in which case
the event is passed as parameter), or strings, in which case the string
is interpreted as a shell command.
see #23
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
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
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 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
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
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
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
Add the possibility to specify a list of commands to be added as
callbacks. Commands will be executed one after the other, waiting for
the previous command to finish execution.
Add controls that allow the user to switch to the next and previous song
in cmus, toggle shuffle and repeat. Pause/play is toggled by clicking on
the song title itself.
fixes#5
This is now much nicer implemented to address issue #3. A user can now
have a configuration parameter mapped to a module instance (via the
module name or the instance name) with the value "left-click",
"right-click", etc., like this:
-m disk:home -p home.left-click="nautilus {instance}"
All callback from a widget into a module (e.g. for retrieving the status
or the criticality state) now get a widget passed. This has the purpose
of allowing a module to store state/widget specific data somewhere. This
way, for instance, it is possible to store the interface name as part of
the widget, thus making it possible to show the status of the correct
interface.
Pass the "output" object to the modules' constructor to allow them to
define their own callbacks.
Any user-provided callbacks take precedence and override those of the
module.
The i3 output now has a separate thread that continuously monitors stdin
for incoming click events. The generic output class also has methods for
registering callbacks (as commands). For now, by default, scroll events
will be used to emulate the next/previous workspace.
It is now possible to add a list of theme configurations in the
"default" section called "cycle". These configuration items will be
cycled through module by module. to create "alternate style" effects.
This is *only* possible in the "default" configuration part, but any
module-specific configurations still take precedence.
Also, removed the capability of per-widget themes. That simply
complicates things and probably doesn't really bring any benefits.
