Do not throw exceptions during exception handling, that causes really
hard-to-interpret error messages.
Instead, log a message and throw outside the exception handler (the code
could do with some cleanup, but is localized enough for now).
see #367
Instead of throwing an error, simply return an empty SSID. Also, for
these cases, make sure the module doesn't output multiple whitespaces as
the end.
fixes#248
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
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
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
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
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.
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 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.
