In order to use symbol files, symbol.json needs to be created manually
now.
Also, remove symbol usage from the prepackaged themes to avoid
breakage.
fixes#216
Redshift might block when no network connectivity is available (if it
tries to determine the location automatically). To avoid this blocking
the whole status line, immediately release the lock in the query thread.
Theme writers are now able to use FontAwesome names and IDs instead of
the symbols itself!
The implementation itself is *slightly* hacky and might get improved in
the future: Upon the first start, a YAML file containing the FontAwesome
symbols is fetched from
https://raw.githubusercontent.com/FortAwesome/Font-Awesome/master/src/icons.yml
Note: This is only done once - to retrigger this (i.e. for an update),
please just delete the file and restart bumblebee-status.
Then, in the *icon* theme itself, you can use ${<name or id>} instead of
the actual symbol.
Names and IDs can be found here:
http://fontawesome.io/cheatsheet/
(simply remove the "fa-" prefix)
An example is provided in themes/icons/awesome-fonts.json.
(finally) fixes#20
sorry for taking so long :)
Move updating of redshift information into a separate thread so that
errors like missing network connectivity do not block the whole status
bar.
fixes#61
List themes only once, even if they are present multiple times in
different locations.
(Yes, I know that list(set(result)) would do the same, but here, I'd
like to not waste memory and be a bit faster).
see #203
Finally fix the datetime import errors by renaming the bumblebee
datetime module (*bad* idea from the start).
Apologies to everyone for whom it now breaks.
This modules makes it very easy to create shortcuts as widgets, for which the user can define the command to be executed when left clicking on it. It supports single or multiple shortcuts
* This module only updates some information on the screen when a new
display is added/removed, hence it makes sense to update it only when
the i3-bar is refreshed.
Add a new parameter engine.workspacewrap (default to true) that, if set
to false, makes the workspace change via mouse wheel stop when hitting
the first/last workspace of an output (identical to how i3wm bar itself
behaves).
fixes#188
Add a parameter that allows the user to enable/disable workspace
scrolling via the status bar.
By default, scrolling is enabled, to disable it, add the following
parameter to your bumblebee-status invokation:
-p <other parameters> engine.workspacewheel=false
see #188
After listening to an audio stream for longer than 10 minutes "mpc -f "tag artist %artist%\ntag title %title%"" will start producing lines with slightly different separation, which caused the bar to fail.
In a theme file, it is now possible to provide an array of "color
definitions", which allow you to use names instead of colors throughout
the theme file.
Currently, only the colorset "wal" is supported, which reads all colors
from the wal JSON file (~/.cache/wal/colors.json) and makes them usable
in the theme (as "foreground", "background", "cursor", "color12", etc.).
An example of this can be found in the theme wal-powerline.
see #185
This file has no actionable code when executed directly from a shell. It contains only a `class` as it is a bumblebee module.
so the shebang should be removed.
On intel pstate drivers only the normal frequency is written to /proc/cpuinfo, not accounting for scaling/turbo.
This should fix that, though it needs testing on other computers (AMD, intel without pstate) because I am not
certain that the file only exists on Intel pstate.
In order to do that, change the theme engine so that a theme can
override settings in the iconsets. Was probably a bug to begin with that
this was not possible.
In python2, filter returned a list, but in python3 it returns an iterator. So
we wrap this in a list() so that it works in both. We also want to count the
unread notifications, so this should be reflected in the code.
Override sys.stdout and sys.stderr in an attempt to enforce utf-8
encoding. Probably this will cause all kinds of weird issues down the
line, but at least, it seems to solve the immediate issue.
fixes#176
Replace textwrap.shorten() with custom implementation, since it is only
available since Python 3.4. While at it, catch i3 exceptions in order to
make unit tests (hopefully) run through.
Also, Updated README.md
see #174
The "base" currency can now be configured using the parameter "source",
and the "symbols" to be resolved can be configured using the parameter
"destination", which is a comma-separated list.
see #169
If a callback command cannot be executed, do not terminate the whole
bar. Furthermore, if such a failure occurs, try to fall back to a
globally (i.e. non widget-specific) command, so that callbacks
registered in the engine itself (such as mouse-wheel scrolling) still
function properly.
fixes#166
* A module can override the method "hidden" to specify when all it's
widgets should be hidden.
* Implement hidden for cmus and spotify
* Fix problem that cmus widgets were not displayed correctly
fixes#157
was having some problems with the current implementation as i have multiple values with the same name in sensors -u.
this way it is unambiguous and *should* just work everywhere with no lm_sensors required, though some distros might move the pseudo file elsewhere, not sure, but thats why it is configurable.
testing would be great.
also, the file is simpler too.
If a configuration parameter is *not* specified with -p on the
commandline, look for a INI style configuration file as fallback in
~/.bumblebee-status.conf or ~/.config/bumblebee-status.conf.
Section must be "module-parameters", like this:
[module-parameters]

fixes#138
The module now creates a widget for each battery device it detects and
shows the status for each of them (I don't know of anyone with more than
a single battery, but if I'm overhauling the module anyhow, might as
well do it comprehensively).
fixes#117
If the current volume and mute status cannot be retrieved, the most
likely explanation is that the pulseaudio daemon is not running.
Automatically start it in such a case.
Also, add a parameter "autostart" to the pulseaudio module to disable
this behaviour in case it causes issues.
see #108
This Module Displays the Status, Song, Artist and Time of the current song played or paused in mocp.
Clicking the Modules toggles play/pause.
I'm no programmer so alteration and feedback is welcome.
Best regards, Chrugi
If data cannot be retrieved for some reason (be pretty generous about
that by catching generic exceptions), instead of terminating the whole
status bar, simply report unknown data.
see #110
Since the module requires the pulseaudio daemon to be running, in order
to query system information such as the default source/sink and the
current volume, start the daemon, if necessary.
fixes#108
A previous commit broke the traffic module by deleting widgets during
each iteration. This is fatal as the widgets contain the traffic
information from the previous iteration, for delta calculation.
Store previous traffic data in the module itself instead.
In order to (hopefully) achieve localization independence, switch from
using pactl for retrieving pulseaudio information to pacmd, which seems
to be unaffected by the LANG environment variable.
fixes#103
To avoid "stray" devices being kept in the list, empty the widgets list
during each iteration and re-populate it from the list of available
interfaces.
fixes#101
The optional parameter "states" can now be used to filter which
interfaces to display. "^" can be used for negation.
For example, to only show "up" interfaces:
-p traffic.states=up
To show all interfaces not in "down" state:
-p traffic.states=^down
fixes#98
psutil.cpu_percent() only outputs to one decimal place anyway, so the trailing 0 is useless.
The prepended 0 is also not important, will only be not 0 at 100% utilization, so why not let it be 100% then and take up one less column otherwise?
No change to default behaviour, but adds boolean to only display used rather than used, total and percentage.
To only show used memory:
-p memory.usedonly=1
OK - I admit it: Mostly for the benefit of Travis and automated testing,
which complains about the DBusException, move to a more generic
exception.
However, this is probably a good idea anyhow, because independently of
the error, setting the song to an empty string is probably the best bet.
Allow the user to filter the state of devices that should be displayed.
It's possible to use both white- and blacklists (and combinations).
For example, to only show devices in state "up":
-p nic.states=up
To only show devices that are not down:
-p nic.states=^down
fixes#84
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 :)
fixes#79
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").
Set the minimum width for uplink and downlink widgets to "down 1000MB",
which should be plenty, and change alignment to right (personally, I
find this looks nicer).
To not have the icons on the left side "jump around" depending on the
value, make them suffixes.
If this solution is not sufficient, alternatively, the widget itself
could perform value padding. In that case, the whole alignment and
min-width settings would be obsolete and the icons could remain on the
left side.
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").
* use psutil instead of "ifconfig" in order to avoid external command
calls
* fix a small bug in the ascii theme (missing colon)
* show statistics per-nic
* 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
Until now, manually specifying an interval did not work, as a cast to
float was missing. Now, it's possible to specify an update interval in
seconds via "-p interval=<interval>"
fixes#54
Seems like subprocess and friends (Popen, communicate) are not so easy
to mock cleanly. Therefore, start from scratch and carefully write test
by test, until (at least) the old test coverage has been restored.
Instead of executing an external call to "uname", use the standard
Python module "platform" to retrieve information about the kernel used.
Positive side-effect: This is portable, if i3 ever exists on Windows :P
Since requests works the same for python2.7 and python3.x, use requests
instead of urllib (which returns a string in python2.7, but byte data in
python3.0, at least).
* Use app-specific API key for bumblebee-status
* Add some parameters (location, unit, update interval)
* Make interval calculation based on time, not number of calls
Somehow, the fix in the previous commit didn't work, it seems that
sometimes epoll() doesn't trigger, even if there is more data in
sys.stdin. I'm sure I'm doing something horribly wrong here.
Anyhow, as a quick fix, check for the open bracket to be sure to not
buffer the first event too long.
Re-enable the possibility to define custom mouse actions by binding
commands to "<alias|module>.<left-click|right-click|...>". These
commands are then executed as shell commands.
fixes#30
Instead of having a thread that runs in the background continuously,
spawn a new one for every update interval. That speeds up the tests
quite a lot.
see #23
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
Quite a lot of modules use the "if higher X -> critical, if higher Y ->
warning" idiom now, so extracted that into a common function for reuse.
see #23
Until now, as soon as a widget registered *any* callback, the default
callbacks (e.g. scroll up/down to go to next/previous workspace) didn't
work anymore, as there was a better match for the general registration
(even though not for the button).
To fix this, merge the callback registration into a flat registration,
where a key is calculated from the ID of the registrar and the
registered button.
see #23
If the computer runs on AC, display that instead of showing "100%" in
the status.
Also, if reading the charging status fails for some reason (except the
computer being on AC), go into critical state and display "n/a".
see #23
Allow modules to define aliases. This replaces the symlink mechanism
that was in place previously, because it was a bit ugly (and confused
code climate).
see #23
Make input thread non-blocking by using select(). This increases the CPU
utilization a bit (depending on the timeout), but makes the thread exit
cleanly, even if an exception is thrown in the main thread.
see #23
If a widget exists for an interface that is not there anymore (i.e. a
tunnel interface that has been removed, or a USB device that has been
unplugged), remove that widget from the list.
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
I cannot get the min_width property to work right now, so in order to
fix the width of the CPU widget, pad the utilization to 3 digits (so
that even 100% aligns nicely).
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
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
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.
see #17
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.
Due to a bug, when the destination was unreachable, the checking thread
would terminate, effectively keeping the widget stuck in "unreachable"
mode.
Now, enable recovery by keeping the thread running even if the target is
not reachable for some time.
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
Allow the user to use all tags read by cmus (cmus-remote -Q|grep ^tag)
as part of the displayed data (plus the special 'tags' "duration" and
"position").
This callback just makes it really hard to see for the user what is
going on. The alias the user provides should *always* match the
instance, so that it can be used in a meaningful way in the click
action, for example (otherwise, something like "nautilus {instance}"
gets really hard to interpret.
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}"
Big oversight in my previous commits: Widgets need to be able to have
specific configurations (i.e. the path for different instances of the
"disk" module has to be different).
To account for that, it is now possible to assign an "alias" to a module
instance using ":" (for example: -m "disk:home"). This alias is then
used for the configuration parameter resolution automatically, for
example:
-m disk:home -p home.path=/home
As a consequence, parameter names in the module code are now relative to
the module, which means: shorter!
Repeatedly querying the interface type the way I'm doing right now
results in "too many files open" pretty quickly. Obviously, it's a bit
of a concern that I am leaking a file descriptor somewhere, but for now,
the quickfix is to cache the type (it shouldn't change, anyhow).
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.
Allow the user to specify arbitrary configuration parameters from the
commandline and evaluate those in the modules (and elsewhere). Re-enable
the CPU module as a first showcase of this functionality.
Allow theme entries to be lists that are then iterated. For this
purpose, extend the Config class so that it can serve as generic store
for data items. That makes it easy to centralize code used for rotation
etc. in a single place.
Yet another bug in the DNF module - really a troublesome one. Only call
the dnf updateinfo every interval, not every second. That significantly
reduces CPU load.
Due to name-clashing of the datetime module's "time" alias, time.sleep
didn't work (as it was looked up from the i3bumblebee module),
consequently, the DNF poll thread exited.
While at it, "beautify" the thread cancelling a bit by waiting until
the main thread is not running anymore.
* cpu+memory: Open "gnome-system-monitor"
* disk: Open nautilus
* pulseaudio: Mute/unmute, open "pavucontrol" on right-click, raise/lower
volume on mouse wheel up/down
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.
Add a module that periodically (by default, once every 30min) calls
"dnf updateinfo" and evaluates the results to report the number of
bugfixes, enhancements, etc.
If there's either too many pending updates, or at least one security
update, the module goes critical.
Add a module that retrieve mute status and volume (left, right, mono)
from pulseaudio. Unfortunately, this module is really, really hacky. It
invokes "pactl" multiple times to get the status and does some ugly
parsing on the output.
Overall, this is pretty brittle and prone to failure, but as I was not
able to find a decent pulseaudio library for Python... Probably, I
haven't searched hard enough, cannot believe such a thing does not
exist.
Add a new module "disk" that takes an optional parameter (the path) and
displays free & total disk space, along with the usage percentage.
Also, added Tunnel/VPN support to the themeing of the "net" module.
First, cache lookups were bugged... Second, the output needs to call
data() first, everything else later.
This is a bit nasty, and I'll consider re-visiting this, but right now,
I don't see any other way, given that modules can now be iterated.
Add a module that displays the status of all NICs (interface name, list
of IPs and state).
In its status, it also exposes whether it's a WiFi or a wired NIC.
For this functionality, additional code was implemented to allow a
module to add multiple elements to the bar at once. The framework calls
the module until its "next()" method return False.
Add functionality to provide lists of values for individual elements of
a theme (e.g. the prefix) and those will be cycled for each call.
This can be used, for example, to show a "charging" symbol for the
battery that continuously goes throw all the battery stages to "animate"
the charging icon.
Font and background colors for warning and critical elements can now be
specified using fg-warning, fg-critical, bg-warning and bg-critical.
Also, optionally, the "urgent" flag will be set towards the i3bar, if
possible.
Format string for strftime is now configurable. Also, changed the
separator for module name vs. arguments to "::" to make it possible to
have ":" as part of the strftime format string (which is useful in most
cases).
Eventually, I'll probably have to come up with a better way, i.e. a
fully-fledged parser, and move away from "special characters", but right
now, the effort seems too much for the gain.
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.
Add the possibility to configure custom separators in the theme file.
These will only be used if the default i3bar separators have been
disabled. Background color will always be taken from the previous
element (to work nicely with my long-term plan, a powerline-like status
line).
Module themes (only!) can now contain state-specific theme information -
for example, the "battery" module has different states for charging and
discharging, and those can have different prefix and postfix
configurations to indicate what is going on.
Individual items in the bar can now be configured with a prefix and a
suffix. It works like this:
* If there is a specific module configuration in the theme
configuration, use that (i.e. { "<modulename>": { "prefix: " a " } })
* Otherwise, if there is a configuration in the "default" section of the
theme, use that
* Otherwise, if the module object itself has a method called like the
required attribute (prefix, suffix), use that
* Otherwise, leave prefix/suffix empty ("")
Add a plugin that displays the remaining battery power in %. This also
introduces the concept of arguments that can be passed to a module
during startup by delimiting the module name with ":", for example:
-m battery:BAT1 to query the BAT1 device.
Note that this works to an arbitray length, i.e. if a module accepts 3
parameters: -m <modulename>:<A>:<B>:<C>
The module gets the arguments as list.
Add - again a very simplistic - method for themeing the output.
Essentially, the plan is to have JSON-formatted configuration files in
bumblebee/themes/ and have a separate class for querying the config
whenever the output needs to know about semantic formatting/coloring.
Note that the theme object is stored on a per-module basis. Right now,
that doesn't have any effect (except looking particularly wasteful), but
the idea is to be able to have different themes for different modules in
the future.
Add a very simplistic framework for loading modules that query system
data. The user can provide a list of modules via an argument switch, and
the name of the module is used to look up a Python module that has to
have a class called "Module".
The outer framework (the outputs, in particular) then uses various query
methods of that class to construct a meaningful output.
Prepare a framework for having modular outputs. Essentially, the main
application uses a output-type object to format strings for the
preamble, the actual data items, and a "postamble" (finalizer). The
printing of that representation, again, is up to the main application,
not the output framework.
Probably, at some point in the future, an interface class will be in
order, but right now, I want to keep it lean - seeing as for the
forseeable future, i3bar is going to be the one and only consumer of
this.
