"""TerminatorConfig by Chris Jones <cmsj@tenshu.net>
|
|
|
|
The config scheme works in layers, with defaults at the base,
|
|
and a simple/flexible class which can be placed over the top
|
|
in multiple layers. This was written for Terminator, but
|
|
could be used generically. Its original use is to guarantee
|
|
default values for any config item, while allowing them to be
|
|
overridden by at least two other stores of configuration values.
|
|
Those being gconf and a plain config file.
|
|
In addition to the value, the default layer must also provide
|
|
the datatype (str, int, float and bool are currently supported).
|
|
values are found as attributes of the TerminatorConfig object.
|
|
Trying to read a value that doesn't exist will raise an
|
|
AttributeError. This is by design. If you want to look something
|
|
up, set a default for it first."""
