When all actions succeed control is granted, if one fail control acces is denied. - - Actions can either be: - + Invocation to an other binding API, either internal or external (eg: a policy service, Alsa UCM, ...) - + C routines from a user provider plugin (eg: policy routine, proprietary code, ...) - + Lua script function. Lua provides access to every AGL appfw functionalities and can be extended from C user provided plugins. - -## Installation - - Controler is a native part of AGL Advance Audio Framework but may be used independently with any other service or application binder. - - Dependencies: the only dependencies are audio-common for JSON-WRAP and Filescan-utils capabilities. - - Controler relies on Lua-5.3, when not needed Lua might be removed at compilation time. - -## Config - -Configuration is loaded dynamically during startup time. The controller scans CONTROL_CONFIG_PATH for a file corresponding to pattern -"onload-bindername-xxxxx.json". When controller runs within AAAA binder it searches for "onload-audio-xxxx.json". First file found in the path the loaded -any other files corresponding to the same pather are ignored and only generate a warning. - -Each bloc in the configuration file are defined with - * label: must be provided is used either for debugging or as input for the action (eg: signal name, control name, ...) - * info: optional used for documentation purpose only - -### Config is organised in 4 sections: - - * metadata - * onload defines the set of action to be executed at startup time - * control defines the set of controls with corresponding actions - * event define the set of actions to be executed when receiving a given signal - -### Metadata - -As today matadata is only used for documentation purpose. - * label + version mandatory - * info optional - -### OnLoad section - -Defines startup time configuration. Onload may provide multiple initialisation profiles, each with a different label. - * label is mandatory. Label is used to select onload profile at initialisation through DispatchOneOnLoad("onload-label") API; - * info is optional - * plugin provides optional unique plugin name. Plugin should follow "onload-bindername-xxxxx.ctlso" patern - and are search into CONTROL_PLUGIN_PATH. When defined controller will execute user provided function context=CTLP_ONLOAD(label,version,info). - The context returned by this routine is provided back to any C routines call later by the controller. Note that Lua2C function - are prefix in Lua script with plugin label (eg: MyPlug: in following config sample) - * lua2c list of Lua commands shipped with provided plugin. - * require list of binding that should be initialised before the controller starts. Note that some listed requirer binding might be absent, - nevertheless any present binding from this list will be started before controller binding, missing ones generate a warning. - * action the list of action to execute during loadtime. Any failure in action will prevent controller binding from starting. - -### Control section - -Defines a list of controls that are accessible through (api="control", verb="request", control="control-label"). - - * label mandatory - * info optional - * permissions Cynara needed privileges to request this control (same as AppFw-V2) - * action the list of actions - -### Event section - -Defines a list of actions to be executed on event reception. Even can do anything a controller can (change state, -send back signal, ...) eg: if a controller subscribes to vehicule speed, then speed-event may ajust master-volume to speed. - - * label mandatory - * info optional - * action the list of actions - -### Actions Categories - -Controler support tree categories of actions. Each action return a status status where 0=success and 1=failure. - * AppFw API, Provides a generic model to request other bindings. Requested binding can be local (eg: ALSA/UCM) or - external (eg: vehicle signalling). - * api provides requested binding API name - * verb provides verb to requested binding - * args optionally provides a jsonc object for targeted binding API. Note that 'args' are statically defined - in JSON configuration file. Controler client may also provided its own arguments from the query list. Targeted - binding receives both arguments defined in the config file and the argument provided by controller client. - * C-API, when defined in the onload section, the plugin may provided C native API with CTLP-CAPI(apiname, label, args, query, context). - Plugin may also create Lua command with CTLP-Lua2C(LuaFuncName, label, args, query, context). Where args+query are JSONC object - and context the value return from CTLP_ONLOAD function. Any missing value is set to NULL. - * Lua-API, when compiled with Lua option, the controller support action defined directly in Lua script. During "onload" phase the - controller search in CONTROL_Lua_PATH file with pattern "onload-bindername-xxxx.lua". Any file corresponding to this pattern - is automatically loaded. Any function defined in those Lua script can be called through a controller action. Lua functions receive - three parameters (label, args, query). - -Note: Lua added functions systematically prefix. AGL standard AppFw functions are prefixed with AGL: (eg: AGL:notice(), AGL_success(), ...). -User Lua functions added though the plugin and CTLP_Lua2C are prefix with plugin label (eg: MyPlug:HelloWorld1). - -### Debugging Facilities - -Controler Lua script are check for syntax from CMAKE template with Luac. When needed to go further an developer API allow to -execute directly Lua command within controller context from Rest/Ws (api=control, verb=lua_doscript). DoScript API takes two -other optional arguments func=xxxx where xxxx is the function to execute within Lua script and args a JSON object to provide -input parameter. When funcname is not given by default the controller try to execute middle filename doscript-xxxx-????.lua. - -When executed from controller Lua script may use any AppFw Apis as well as any L2C user defined commands in plugin. -

If you find bug please report. + +### Adding Lua command from User Plugin + +User Plugin is optional and may provide either native C-action accessible directly from controller actions as defined in +JSON config file, or alternatively may provide at set of Lua commands usable inside any script (onload, control,event). A simple +plugin that provide both natice C API and Lua commands is provided as example (see ctl-plugin-sample.c). Technically a +plugin is a simple sharelibrary and any code fitting in sharelib might be used as a plugin. Developer should nevertheless +not forget that except when no-concurrency flag was at binding construction time, any binding should to be thread safe. + +A plugin must be declare with CTLP_REGISTER("MyCtlSamplePlugin"). This entry point defines a special structure that is check +at plugin load time by the controller. Then you have an optional init routine declare with CTLP_ONLOAD(label, version, info). +This init routine receives controller onload profile as selected by DispatchOnLoad("profile"). The init routine may create +a plugin context that is later one presented to every plugin API this for both LUA and native C ones. Then each: + + * C API declare with CTLP_CAPI (MyCFunction, label, argsJ, queryJ, context) {your code}. Where: + * MyFunction is your function + * Label is a string containing the name of your function + * ArgsJ a json_object containing the argument attach the this control in JSON config file. + * context your C context as return from CTLP_ONLOAD + + * Lua API declarewith TLP_LUA2C (MyLuaCFunction, label, argsJ, context) {your code}. Where + * MyLuaCFunction is both the name of your C function and Lua command + * Label your function name as a string + * Args the arguments passed this time from Lua script and not from Json config file. + * Query is not provided as LuaC function are called from a script and not directly from controller action list. + +Warning: Lua samples use with controller enforce strict mode. As a result every variables should be declare either as +local or as global. Unfortunately "luac" is not smart enough to handle strict mode at build time and errors only appear +at run time. Because of this strict mode every global variables (which include functions) should be prefix by '_'. +Note that LUA require an initialisation value for every variables and declaring something like "local myvar" wont +allocate "myvar" + +### Debugging Facilities + +Controler Lua script are check for syntax from CMAKE template with Luac. When needed to go further an developer API allow to +execute directly Lua command within controller context from Rest/Ws (api=control, verb=lua_doscript). DoScript API takes two +other optional arguments func=xxxx where xxxx is the function to execute within Lua script and args a JSON object to provide +input parameter. When funcname is not given by default the controller try to execute middle filename doscript-xxxx-????.lua. + +When executed from controller Lua script may use any AppFw Apis as well as any L2C user
