The 'GI.Gio.Objects.Settings.Settings' class provides a convenient API for storing and retrieving
application settings.

Reads and writes can be considered to be non-blocking.  Reading
settings with 'GI.Gio.Objects.Settings.Settings' is typically extremely fast: on
approximately the same order of magnitude (but slower than) a
'GI.GLib.Structs.HashTable.HashTable' lookup.  Writing settings is also extremely fast in terms
of time to return to your application, but can be extremely expensive
for other threads and other processes.  Many settings backends
(including dconf) have lazy initialisation which means in the common
case of the user using their computer without modifying any settings
a lot of work can be avoided.  For dconf, the D-Bus service doesn\'t
even need to be started in this case.  For this reason, you should
only ever modify 'GI.Gio.Objects.Settings.Settings' keys in response to explicit user action.
Particular care should be paid to ensure that modifications are not
made during startup -- for example, when setting the initial value
of preferences widgets.  The built-in 'GI.Gio.Objects.Settings.settingsBind' functionality
is careful not to write settings in response to notify signals as a
result of modifications that it makes to widgets.

When creating a GSettings instance, you have to specify a schema
that describes the keys in your settings and their types and default
values, as well as some other information.

Normally, a schema has a fixed path that determines where the settings
are stored in the conceptual global tree of settings. However, schemas
can also be \'[relocatable][gsettings-relocatable]\', i.e. not equipped with
a fixed path. This is
useful e.g. when the schema describes an \'account\', and you want to be
able to store a arbitrary number of accounts.

Paths must start with and end with a forward slash character (\'\/\')
and must not contain two sequential slash characters.  Paths should
be chosen based on a domain name associated with the program or
library to which the settings belong.  Examples of paths are
\"\/org\/gtk\/settings\/file-chooser\/\" and \"\/ca\/desrt\/dconf-editor\/\".
Paths should not start with \"\/apps\/\", \"\/desktop\/\" or \"\/system\/\" as
they often did in GConf.

Unlike other configuration systems (like GConf), GSettings does not
restrict keys to basic types like strings and numbers. GSettings stores
values as 'GVariant', and allows any 'GI.GLib.Structs.VariantType.VariantType' for keys. Key names
are restricted to lowercase characters, numbers and \'-\'. Furthermore,
the names must begin with a lowercase character, must not end
with a \'-\', and must not contain consecutive dashes.

Similar to GConf, the default values in GSettings schemas can be
localized, but the localized values are stored in gettext catalogs
and looked up with the domain that is specified in the
@gettext-domain@ attribute of the \<schemalist> or \<schema>
elements and the category that is specified in the @l10n@ attribute of
the \<default> element. The string which is translated includes all text in
the \<default> element, including any surrounding quotation marks.

The @l10n@ attribute must be set to @messages@ or @time@, and sets the
<https://www.gnu.org/software/gettext/manual/html_node/Aspects.html#index-locale-categories-1 locale category for
translation>.
The @messages@ category should be used by default; use @time@ for
translatable date or time formats. A translation comment can be added as an
XML comment immediately above the \<default> element — it is recommended to
add these comments to aid translators understand the meaning and
implications of the default value. An optional translation @context@
attribute can be set on the \<default> element to disambiguate multiple
defaults which use the same string.

For example:
>
> <!-- Translators: A list of words which are not allowed to be typed, in
>      GVariant serialization syntax.
>      See: https://developer.gnome.org/glib/stable/gvariant-text.html -->
> <default l10n='messages' context='Banned words'>['bad', 'words']</default>


Translations of default values must remain syntactically valid serialized
@/GVariants/@ (e.g. retaining any surrounding quotation marks) or runtime
errors will occur.

GSettings uses schemas in a compact binary form that is created
by the [glib-compile-schemas][glib-compile-schemas]
utility. The input is a schema description in an XML format.

A DTD for the gschema XML format can be found here:
<https://git.gnome.org/browse/glib/tree/gio/gschema.dtd gschema.dtd>

The [glib-compile-schemas][glib-compile-schemas] tool expects schema
files to have the extension @.gschema.xml@.

At runtime, schemas are identified by their id (as specified in the
id attribute of the \<schema> element). The convention for schema
ids is to use a dotted name, similar in style to a D-Bus bus name,
e.g. \"org.gnome.SessionManager\". In particular, if the settings are
for a specific service that owns a D-Bus bus name, the D-Bus bus name
and schema id should match. For schemas which deal with settings not
associated with one named application, the id should not use
StudlyCaps, e.g. \"org.gnome.font-rendering\".

In addition to 'GVariant' types, keys can have types that have
enumerated types. These can be described by a \<choice>,
\<enum> or \<flags> element, as seen in the
[example][schema-enumerated]. The underlying type of such a key
is string, but you can use 'GI.Gio.Objects.Settings.settingsGetEnum', 'GI.Gio.Objects.Settings.settingsSetEnum',
'GI.Gio.Objects.Settings.settingsGetFlags', 'GI.Gio.Objects.Settings.settingsSetFlags' access the numeric values
corresponding to the string value of enum and flags keys.

An example for default value:
>
><schemalist>
>  <schema id="org.gtk.Test" path="/org/gtk/Test/" gettext-domain="test">
>
>    <key name="greeting" type="s">
>      <default l10n="messages">"Hello, earthlings"</default>
>      <summary>A greeting</summary>
>      <description>
>        Greeting of the invading martians
>      </description>
>    </key>
>
>    <key name="box" type="(ii)">
>      <default>(20,30)</default>
>    </key>
>
>    <key name="empty-string" type="s">
>      <default>""</default>
>      <summary>Empty strings have to be provided in GVariant form</summary>
>    </key>
>
>  </schema>
></schemalist>


An example for ranges, choices and enumerated types:
>
><schemalist>
>
>  <enum id="org.gtk.Test.myenum">
>    <value nick="first" value="1"/>
>    <value nick="second" value="2"/>
>  </enum>
>
>  <flags id="org.gtk.Test.myflags">
>    <value nick="flag1" value="1"/>
>    <value nick="flag2" value="2"/>
>    <value nick="flag3" value="4"/>
>  </flags>
>
>  <schema id="org.gtk.Test">
>
>    <key name="key-with-range" type="i">
>      <range min="1" max="100"/>
>      <default>10</default>
>    </key>
>
>    <key name="key-with-choices" type="s">
>      <choices>
>        <choice value='Elisabeth'/>
>        <choice value='Annabeth'/>
>        <choice value='Joe'/>
>      </choices>
>      <aliases>
>        <alias value='Anna' target='Annabeth'/>
>        <alias value='Beth' target='Elisabeth'/>
>      </aliases>
>      <default>'Joe'</default>
>    </key>
>
>    <key name='enumerated-key' enum='org.gtk.Test.myenum'>
>      <default>'first'</default>
>    </key>
>
>    <key name='flags-key' flags='org.gtk.Test.myflags'>
>      <default>["flag1","flag2"]</default>
>    </key>
>  </schema>
></schemalist>


== Vendor overrides

Default values are defined in the schemas that get installed by
an application. Sometimes, it is necessary for a vendor or distributor
to adjust these defaults. Since patching the XML source for the schema
is inconvenient and error-prone,
[glib-compile-schemas][glib-compile-schemas] reads so-called vendor
override\' files. These are keyfiles in the same directory as the XML
schema sources which can override default values. The schema id serves
as the group name in the key file, and the values are expected in
serialized GVariant form, as in the following example:
>
>    [org.gtk.Example]
>    key1='string'
>    key2=1.5


glib-compile-schemas expects schema files to have the extension
@.gschema.override@.

== Binding

A very convenient feature of GSettings lets you bind 'GI.GObject.Objects.Object.Object' properties
directly to settings, using 'GI.Gio.Objects.Settings.settingsBind'. Once a GObject property
has been bound to a setting, changes on either side are automatically
propagated to the other side. GSettings handles details like mapping
between GObject and GVariant types, and preventing infinite cycles.

This makes it very easy to hook up a preferences dialog to the
underlying settings. To make this even more convenient, GSettings
looks for a boolean property with the name \"sensitivity\" and
automatically binds it to the writability of the bound setting.
If this \'magic\' gets in the way, it can be suppressed with the
@/G_SETTINGS_BIND_NO_SENSITIVITY/@ flag.

## Relocatable schemas # {@/gsettings/@-relocatable}

A relocatable schema is one with no @path@ attribute specified on its
\<schema> element. By using 'GI.Gio.Objects.Settings.settingsNewWithPath', a 'GI.Gio.Objects.Settings.Settings' object
can be instantiated for a relocatable schema, assigning a path to the
instance. Paths passed to 'GI.Gio.Objects.Settings.settingsNewWithPath' will typically be
constructed dynamically from a constant prefix plus some form of instance
identifier; but they must still be valid GSettings paths. Paths could also
be constant and used with a globally installed schema originating from a
dependency library.

For example, a relocatable schema could be used to store geometry information
for different windows in an application. If the schema ID was
@org.foo.MyApp.Window@, it could be instantiated for paths
@\/org\/foo\/MyApp\/main\/@, @\/org\/foo\/MyApp\/document-1\/@,
@\/org\/foo\/MyApp\/document-2\/@, etc. If any of the paths are well-known
they can be specified as \<child> elements in the parent schema, e.g.:
>
><schema id="org.foo.MyApp" path="/org/foo/MyApp/">
>  <child name="main" schema="org.foo.MyApp.Window"/>
></schema>


## Build system integration # {@/gsettings/@-build-system}

GSettings comes with autotools integration to simplify compiling and
installing schemas. To add GSettings support to an application, add the
following to your @configure.ac@:
>
>GLIB_GSETTINGS


In the appropriate @Makefile.am@, use the following snippet to compile and
install the named schema:
>
>gsettings_SCHEMAS = org.foo.MyApp.gschema.xml
>EXTRA_DIST = $(gsettings_SCHEMAS)
>
>@GSETTINGS_RULES@


No changes are needed to the build system to mark a schema XML file for
translation. Assuming it sets the @gettext-domain@ attribute, a schema may
be marked for translation by adding it to @POTFILES.in@, assuming gettext
0.19 is in use (the preferred method for translation):
>
>data/org.foo.MyApp.gschema.xml


Alternatively, if intltool 0.50.1 is in use:
>
>[type: gettext/gsettings]data/org.foo.MyApp.gschema.xml


GSettings will use gettext to look up translations for the \<summary> and
\<description> elements, and also any \<default> elements which have a @l10n@
attribute set. Translations must not be included in the @.gschema.xml@ file
by the build system, for example by using intltool XML rules with a
@.gschema.xml.in@ template.

If an enumerated type defined in a C header file is to be used in a GSettings
schema, it can either be defined manually using an \<enum> element in the
schema XML, or it can be extracted automatically from the C header. This
approach is preferred, as it ensures the two representations are always
synchronised. To do so, add the following to the relevant @Makefile.am@:
>
>gsettings_ENUM_NAMESPACE = org.foo.MyApp
>gsettings_ENUM_FILES = my-app-enums.h my-app-misc.h


@gsettings_ENUM_NAMESPACE@ specifies the schema namespace for the enum files,
which are specified in @gsettings_ENUM_FILES@. This will generate a
@org.foo.MyApp.enums.xml@ file containing the extracted enums, which will be
automatically included in the schema compilation, install and uninstall
rules. It should not be committed to version control or included in
@EXTRA_DIST@.

{- |
Creates a new 'GI.Gio.Objects.Settings.Settings' object with a given schema, backend and
path.

It should be extremely rare that you ever want to use this function.
It is made available for advanced use-cases (such as plugin systems
that want to provide access to schemas loaded from custom locations,
etc).

At the most basic level, a 'GI.Gio.Objects.Settings.Settings' object is a pure composition of
4 things: a 'GI.Gio.Structs.SettingsSchema.SettingsSchema', a 'GI.Gio.Objects.SettingsBackend.SettingsBackend', a path within that
backend, and a 'GI.GLib.Structs.MainContext.MainContext' to which signals are dispatched.

This constructor therefore gives you full control over constructing
'GI.Gio.Objects.Settings.Settings' instances.  The first 3 parameters are given directly as
/@schema@/, /@backend@/ and /@path@/, and the main context is taken from the
thread-default (as per 'GI.Gio.Objects.Settings.settingsNew').

If /@backend@/ is 'Nothing' then the default backend is used.

If /@path@/ is 'Nothing' then the path from the schema is used.  It is an
error if /@path@/ is 'Nothing' and the schema has no path of its own or if
/@path@/ is non-'Nothing' and not equal to the path that the schema does
have.

Creating a 'GI.Gio.Objects.Settings.Settings' object with a different backend allows accessing
settings from a database other than the usual one. For example, it may make
sense to pass a backend corresponding to the \"defaults\" settings database on
the system to get a settings object that modifies the system default
settings instead of the settings for this user.

Create a binding between the /@key@/ in the /@settings@/ object
and the property /@property@/ of /@object@/.

The binding uses the default GIO mapping functions to map
between the settings and property values. These functions
handle booleans, numeric types and string types in a
straightforward way. Use @/g_settings_bind_with_mapping()/@ if
you need a custom mapping, or map between types that are not
supported by the default mapping functions.

Unless the /@flags@/ include 'GI.Gio.Flags.SettingsBindFlagsNoSensitivity', this
function also establishes a binding between the writability of
/@key@/ and the \"sensitive\" property of /@object@/ (if /@object@/ has
a boolean property by that name). See 'GI.Gio.Objects.Settings.settingsBindWritable'
for more details about writable bindings.

Note that the lifecycle of the binding is tied to /@object@/,
and that you can have only one binding per object property.
If you bind the same property twice on the same object, the second
binding overrides the first one.

Creates a 'GI.Gio.Interfaces.Action.Action' corresponding to a given 'GI.Gio.Objects.Settings.Settings' key.

The action has the same name as the key.

The value of the key becomes the state of the action and the action
is enabled when the key is writable.  Changing the state of the
action results in the key being written to.  Changes to the value or
writability of the key cause appropriate change notifications to be
emitted for the action.

For boolean-valued keys, action activations take no parameter and
result in the toggling of the value.  For all other types,
activations take the new value for the key (which must have the
correct type).

{- |
Gets the value that is stored at /@key@/ in /@settings@/, subject to
application-level validation\/mapping.

You should use this function when the application needs to perform
some processing on the value of the key (for example, parsing).  The
/@mapping@/ function performs that processing.  If the function
indicates that the processing was unsuccessful (due to a parse error,
for example) then the mapping is tried again with another value.

This allows a robust \'fall back to defaults\' behaviour to be
implemented somewhat automatically.

The first value that is tried is the user\'s setting for the key.  If
the mapping function fails to map this value, other values may be
tried in an unspecified order (system or site defaults, translated
schema default values, untranslated schema default values, etc).

If the mapping function fails for all possible values, one additional
attempt is made: the mapping function is called with a 'Nothing' value.
If the mapping function still indicates failure at this point then
the application will be aborted.

The result parameter for the /@mapping@/ function is pointed to a
@/gpointer/@ which is initially set to 'Nothing'.  The same pointer is given
to each invocation of /@mapping@/.  The final value of that @/gpointer/@ is
what is returned by this function.  'Nothing' is valid; it is returned
just as any other value would be.

Checks the \"user value\" of a key, if there is one.

The user value of a key is the last value that was set by the user.

After calling 'GI.Gio.Objects.Settings.settingsReset' this function should always return
'Nothing' (assuming something is not wrong with the system
configuration).

It is possible that 'GI.Gio.Objects.Settings.settingsGetValue' will return a different
value than this function.  This can happen in the case that the user
set a value for a key that was subsequently locked down by the system
administrator -- this function will return the user\'s old value.

This function may be useful for adding a \"reset\" option to a UI or
for providing indication that a particular value has been changed.

It is a programmer error to give a /@key@/ that isn\'t contained in the
schema for /@settings@/.

Ensures that all pending operations are complete for the default backend.

Writes made to a 'GI.Gio.Objects.Settings.Settings' are handled asynchronously.  For this
reason, it is very unlikely that the changes have it to disk by the
time @/g_settings_set()/@ returns.

This call will block until all of the writes have made it to the
backend.  Since the mainloop is not running, no change notifications
will be dispatched during this call (but some may be queued by the
time the call is done).
