GI.Gio.Interfaces.DebugController
Description
DebugController is an interface to expose control of debugging features and
debug output.
It is implemented on Linux using DebugControllerDBus, which exposes a D-Bus
interface to allow authenticated peers to control debug features in this
process.
Whether debug output is enabled is exposed as
DebugController:debug-enabled. This controls logSetDebugEnabled by
default. Application code may connect to the Object::notify signal for it
to control other parts of its debug infrastructure as necessary.
If your application or service is using the default GLib log writer function,
creating one of the built-in implementations of DebugController should be
all that’s needed to dynamically enable or disable debug output.

Properties
debugEnabled
True if debug output should be exposed (for example by forwarding it to
the journal), False otherwise.
Since: 2.72
constructDebugControllerDebugEnabled :: (IsDebugController o, MonadIO m) => Bool -> m (GValueConstruct o) Source #
Construct a GValueConstruct with valid value for the “debug-enabled” property. This is rarely needed directly, but it is used by new.
getDebugControllerDebugEnabled :: (MonadIO m, IsDebugController o) => o -> m Bool Source #
Get the value of the “debug-enabled” property.
When overloading is enabled, this is equivalent to
get debugController #debugEnabled
setDebugControllerDebugEnabled :: (MonadIO m, IsDebugController o) => o -> Bool -> m () Source #
Set the value of the “debug-enabled” property.
When overloading is enabled, this is equivalent to
setdebugController [ #debugEnabled:=value ]
