We need to use WpSpaJson to parse the values in WpSettings. This is because the
wireplumber configuration is written in JSON, so WpSettings should only hold
JSON values. To fix this, 2 API changes have been done:
- wp_settings_get_int() only accepts gint values, instead of gint64 values. This
is because the WpSpaJson API only parses int values, like spa_json_parse_int().
- wp_settings_get_string() now returns a newly allocated string, this is because
the string needs to be decoded in case it has quotes.
- add integer and string version of the APIs,
- Also Refine the APIs, return value to indicate the setting existance
and a new param to return the value of the setting.
- add their lua bindings as well, in lua binding the return value nil
indicates that the setting is not defnied.
- Add corresponding C and lua tests as well.
- Add a few handy debug msgs.
- settings.c tests conf file loading & parsing, metadata updates,
wpsetttings object creation and its API.
- settings.lua tests the API from lua scripts.
- Add a sample settings.conf file, this file contains sections copied
over from client.conf along with the settings section. Add a file
each for wp side and lua side of scripts.
- Make changes in base test infrastructure to take a custom conf file.
- Enhance the wp_settings_get_instance_api() to be take metadata_name
parameter. So, Wpsetttings is now a singleton instance for a given
metadata file.
- Enhance the m-settings module also to be take metadata_name parameter.
this is handy for lua side of tests as its cumbersome to do this is
lua.
- WpSettings is a singleton object which attaches itself to the core
and registry, it provides a get_instance () for its clients.
- WpSettings provides API to get/set wireplumber settings and rules.
- main.c loads the new object and makes sure it is available for
for all the modules and scripts. This is achieved by introducing
a new activation step.
- Add the lua bindings for get_setting API.
