[Output] Only draw widget when full text is not empty 2017-05-26 21:36:01 +02:00

fdcc908d83 [core] Use class theme, if no specific module theme matches
For modules that use aliases, until now, *only* the alias theme was
considered. This is typically a bad idea (tm), as the "generic" case is
that of a module theme (e.g. "disk", not that of a theme per instance of
the module (i.e. "home", "root", etc.)).

Therefore, introduce the concept of a "class" theme that can be
optionall overridden by a specific module theme.

As a pleasant side-effect, this should bring back the disk icons for all
instances of the disk module :)

928940d848 [core] Add a "scrollable" modifier for widget texts callbacks
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)

92be7d3020 [core] Added min-width and alignment themeing
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").

251f8d2e9f [core] Add debugging capabilities
* 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.

71582cbcd7 [modules/ping] Re-enable ping module
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.

a045962d00 [modules/nic] Re-enable NIC module
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".

225d471c6a [modules/cpu] Add configurable warning and critical thresholds

e72c25b0bc [core] Add input processing
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.

f645203579 [core] Widget creation/update overhaul
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)

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.

60d96506e8 [modules/layout] Add rotation logic and language parameter
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

e8b3dfb4ef [modules/xrandr] Add display on/off toggling
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)
