"""
|
|
Loads all of the paths specified (if any).
|
|
|
|
The path can either be a single string identifying one explicit
|
|
location, otherwise you can pass in a series of locations to scan
|
|
via a list.
|
|
|
|
If no path is specified then a default list is used.
|
|
|
|
By default we cache our responses so that subsiquent calls does not
|
|
cause the content to be retrieved again. Setting this to False does
|
|
mean more then one call can be made to retrieve the (same) data. This
|
|
method can be somewhat inefficient if disabled and you're set up to
|
|
make remote calls. Only disable caching if you understand the
|
|
consequences.
|
|
|
|
You can alternatively set the cache value to an int identifying the
|
|
number of seconds the previously retrieved can exist for before it
|
|
should be considered expired.
|
|
|
|
It's also worth nothing that the cache value is only set to elements
|
|
that are not already of subclass ConfigBase()
|
|
|
|
recursion defines how deep we recursively handle entries that use the
|
|
`import` keyword. This keyword requires us to fetch more configuration
|
|
from another source and add it to our existing compilation. If the
|
|
file we remotely retrieve also has an `import` reference, we will only
|
|
advance through it if recursion is set to 2 deep. If set to zero
|
|
it is off. There is no limit to how high you set this value. It would
|
|
be recommended to keep it low if you do intend to use it.
|
|
|
|
insecure includes by default are disabled. When set to True, all
|
|
Apprise Config files marked to be in STRICT mode are treated as being
|
|
in ALWAYS mode.
|
|
|
|
Take a file:// based configuration for example, only a file:// based
|
|
configuration can import another file:// based one. because it is set
|
|
to STRICT mode. If an http:// based configuration file attempted to
|
|
import a file:// one it woul fail. However this import would be
|
|
possible if insecure_includes is set to True.
|
|
|
|
There are cases where a self hosting apprise developer may wish to load
|
|
configuration from memory (in a string format) that contains import
|
|
entries (even file:// based ones). In these circumstances if you want
|
|
these includes to be honored, this value must be set to True.
