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).
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 - 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.
