- * `packagegroup-agl-image-minimal` - * `packagegroup-agl-image-ivi` - * `packagegroup-agl-demo-platform` - -### packagegroup-agl-appfw* - -These packagegroups contain packages for the AGL distribution's -Application Framework. -Subsystem should maintain `packagegroup-agl-appfw-[subsystem].bb`, which -should hold sufficient packages for the Application Framework. - -Subsystems also can maintain their own packagegroups using appropriate -`recipes-*/`. -For example, Qt5 has two packagegroups in `meta-agl-demo`: -`packagegroup-agl-appfw-native-qt5` and `packagegroup-agl-demo-qt-examples`, -which are under `recipes-qt/`. - -The `packagegroup-agl-appfw-native-qt5` is included by -`packagegroup-agl-appfw-native` because Qt5 belongs to native application -framework of AGL Distro. - -Because the `packagegroup-agl-demo-qt-examples` is not mandatory for -the AGL Application Framework and the AGL DEMO, the packagegroup is added -to the layer's `local.conf` file only when needed. -

-# Advanced Usage - -This topic describes some advanced ways of using the CMake templates. - -## Building a Widget - -To build a widget, you need a `config.xml` file that describes -your application (widget) and how the Application Framework launches it. -Your repository contains a simple default file named -`config.xml.in` that should work for simple applications and should -not require interactions with other bindings. - -It is also recommended that you use the sample configuration -file that you can find in the location. -This file is named `config.xms.in.sample` and is more complete. -Copy the sample file to your `conf.d/wgt` directory and name it -`config.xml.in`. -Once you have your copy, edit the file to fit your needs. - -**CAUTION:** The default file is only meant to be used for a -simple widget application. -For more complicated applications that need to export -their API, or ship several applications in one widget -need to use the provided `config.xml.in.sample` file, which has -all new Application Framework features explained and provides -examples. - -## Using CMake Template Macros - -To leverage all CMake template features, you must specify properties -on your targets. -Some macros do not work unless you specify the target type. -If you do not specify a type (e.g. a custom target such as an -HTML5 application), the macro uses the `LABELS` property to -determine the target type. - -The `LABELS` property can be set to the values shown in the -[Target Properties](configuring-cmake.html#target-properties) -Section. - -Aside from those values, the following optional values can be -assigned to the `LABELS` property. -These values define the resource types that make up your test materials: - -- **TEST-CONFIG**: JSON configuration files used by the `afb-test` - binding. - These files execute the tests. -- **TEST-DATA**: Resources used to test your binding. - Minimally, you need a test plan. - You should also consider fixtures and any files required by your tests. - These required files appear as part of a separate test widget. -- **TEST-PLUGIN**: A shared library used as a binding plugin. - A binding loads the library as a plugin to extend the binding's functionality. - You should use a special file extension when you name the library - by using the `SUFFIX` CMake target property. - If you do not choose an extension, `.ctlso` is used by default. -- **TEST-HTDOCS**: The root directory of a web application. - This target has to build its directory and put its files in - the `${CMAKE_CURRENT_BINARY_DIR}/${TARGET_NAME}` directory. -- **TEST-EXECUTABLE**: The entry point of your application executed by the AGL - Application Framework. -- **TEST-LIBRARY**: An external third-party library bundled with the binding - for its own purpose. - The platform does not provide this library. - -Following is a mapping between `LABELS` and directories where files reside in -the widget: - -- **EXECUTABLE** : \<wgtrootdir\>/bin -- **BINDING-CONFIG** : \<wgtrootdir\>/etc -- **BINDING** | **BINDINGV2** | **BINDINGV3** | **LIBRARY** : \<wgtrootdir\>/lib -- **PLUGIN** : \<wgtrootdir\>/lib/plugins -- **HTDOCS** : \<wgtrootdir\>/htdocs -- **BINDING-DATA** : \<wgtrootdir\>/var -- **DATA** : \<wgtrootdir\>/var - -Following is a mapping between test-dedicated `LABELS` and directories where -files reside in the widget: - -- **TEST-EXECUTABLE** : \<wgtrootdir\>/bin -- **TEST-CONFIG** : \<TESTwgtrootdir\>/etc -- **TEST-PLUGIN** : \<wgtrootdir\>/lib/plugins -- **TEST-HTDOCS** : \<wgtrootdir\>/htdocs -- **TEST-DATA** : \<TESTwgtrootdir\>/var - -**TIP:** Use the prefix `afb-` (Application Framework Binding) -with your **BINDING** targets. - -Following is an example that sets the `LABELS` and `OUTPUT_NAME` properties: - -```cmake -SET_TARGET_PROPERTIES(${TARGET_NAME} PROPERTIES - LABELS "HTDOCS" - OUTPUT_NAME dist.prod - ) -``` - -**NOTE**: You do not need to specify an **INSTALL** command for these - targets. - Installation is handled by the template and installs using the - following path : **${CMAKE_INSTALL_PREFIX}/${PROJECT_NAME}** - - Also, if you want to set and use `rpath` with your target, you should use - and set the target property `INSTALL_RPATH`. - -## Adding an External Third-Party Library - -You can add an external third-party library that is built, linked, -and shipped with the project. -Or, you can link and ship the library only with the project. - -### Building, Linking, and Shipping an External Library with the Project - -If you need to include an external library that is not shipped -with the project, you can bundle the required library in the -`lib` widget directory. - -Templates includes facilities to help you work with external -libraries. -A standard method is to declare as many CMake ExternalProject -modules as you need to match the number of needed libraries. - -An ExternalProject module is a special CMake module that lets you define how -to download, update, patch, configure, build, and install an external project. -The project does not need to be a CMake project. -Additionally, you can provide custom steps to account for special -needs using ExternalProject step. -See the CMake -[ExternalProject documentation site](https://cmake.org/cmake/help/v3.5/module/ExternalProject.html?highlight=externalproject) -for more information. - -Following is an example that includes the `mxml` library for the -[unicens2-binding](https://github.com/iotbzh/unicens2-binding) -project: - -```cmake -set(MXML external-mxml) -set(MXML_SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/mxml) -ExternalProject_Add(${MXML} - GIT_REPOSITORY https://github.com/michaelrsweet/mxml.git - GIT_TAG release-2.10 - SOURCE_DIR ${MXML_SOURCE_DIR} - CONFIGURE_COMMAND ./configure --build x86_64 --host aarch64 - BUILD_COMMAND make libmxml.so.1.5 - BUILD_IN_SOURCE 1 - INSTALL_COMMAND "" -) - -PROJECT_TARGET_ADD(mxml) - -add_library(${TARGET_NAME} SHARED IMPORTED GLOBAL) - -SET_TARGET_PROPERTIES(${TARGET_NAME} PROPERTIES - LABELS LIBRARY - IMPORTED_LOCATION ${MXML_SOURCE_DIR}/libmxml.so.1 - INTERFACE_INCLUDE_DIRECTORIES ${MXML_SOURCE_DIR} -) - -add_dependencies(${TARGET_NAME} ${MXML}) -``` - -The example defines an external project that drives the building of the library. -The example also defines a new CMake target whose type is **IMPORTED**. -The **IMPORTED** target type indicates the target has yet to be built using -CMake but is available at the location defined using the **IMPORTED_LOCATION** -target property. - -You might want to build the library as **SHARED** or **STATIC** depending on your needs -and goals. -Next, the example only has to modify the external project configure step and change -the filename used by **IMPORTED** library target defined after external project. - -The target's **LABELS** property is set to **LIBRARY** to ship it in the widget. - -In this example, the Unicens project also needs header -information from this library. -Consequently, the **INTERFACE_INCLUDE_DIRECTORIES** target property -is used. -Setting that property when another target links to that imported target -allows access to included directories. - -Finally, the example binds the target to the external project -by using a CMake dependency. - -The target can now be linked and used like any other CMake target. - -### Link and Ship an External Library with the Project - -If you already have a binary version of the library that you want to use and you -cannot or do not want to build the library, you can use the **IMPORTED** -library target. - -To illustrate, consider the same example in the previous section. -Following are the relevant modifications: - -```cmake -PROJECT_TARGET_ADD(mxml) - -add_library(${TARGET_NAME} SHARED IMPORTED GLOBAL) - -SET_TARGET_PROPERTIES(${TARGET_NAME} PROPERTIES - LABELS LIBRARY - IMPORTED_LOCATION /path_to_library/libmxml.so.1 - INTERFACE_INCLUDE_DIRECTORIES /path_to_mxml/include/dir -) -``` - -In the previous example, notice the changes to the -`IMPORTED_LOCATION` and `INTERFACE_INCLUDE_DIRECTORIES` statements. -These locate the binary version of the library. - -Finally, you can link any other library or executable target with this imported -library just as you would for any other target. - -## Macro Reference - -Following are several macros that are useful for advanced CMake usage. - -### PROJECT_TARGET_ADD - -This macro adds the target to your project. -Following is a typical example that adds the target to your project. -You need to provide the name of your target as the macro's parameter: - -Example: - -```cmake -PROJECT_TARGET_ADD(low-can-demo) -``` - -The macro makes the variable `${TARGET_NAME}` available and it is defined -using the specified name (e.g. `low-can-demo`). -The variable changes each time the `PROJECT_TARGET_ADD` macro is called. - -### project_subdirs_add - -This macro searches within specified subfolders of the CMake project for -any `CMakeLists.txt` file. -If the file is found, it is added to your project. -You can use this macro in a hybrid application (e.g. where the binding -exists in a subfolder). - -The following example searches within all subfolders: - -Usage : - -```cmake -project_subdirs_add() -``` - -You might want to restrict the subfolders being searched. -If so, you can specify a -[globbing](https://en.wikipedia.org/wiki/Glob_(programming)) pattern -as the argument. -Doing so effectively creates a search filter. - -Following is an example that specifies all directories that begin -with a number, are followed by the dash character, and then followed -by any characters: - -```cmake -project_subdirs_add("[0-9]-*") -``` - -### set_openapi_filename - -This macro is used with a **BINDINGV2** target and defines the -binding definition filename. -You can use it to also define a relative path to -the current `CMakeLists.txt` file. - -If you do not use this macro to specify the name of your definition file, -the default one is used, which is `${OUTPUT_NAME}-apidef` and uses -**OUTPUT_NAME** as the [target property]. - -**CAUTION** When specifying the binding definition filename, -you must not use the file's extension as part of the name. -Following is an example: - -```cmake -set_openapi_filename('binding/mybinding_definition') -``` - -[target property]: https://cmake.org/cmake/help/v3.6/prop_tgt/OUTPUT_NAME.html "OUTPUT_NAME property documentation" - -### add_input_files - -This macro creates a custom target dedicated for HTML5 and data resource files. -The macro provides syntax and schema verification for different languages that -include LUA, JSON and XML. - -Alongside the macro are tools used to check files. -You can configure the tools by setting the -following variables: - -- XML_CHECKER: Uses **xmllint** that is provided with major linux distributions. -- LUA_CHECKER: Uses **luac** that is provided with major linux distributions. -- JSON_CHECKER: Currently, not used by any tools. - -Following is an example: - -```cmake -add_input_file("${MY_FILES_LIST}") -``` - -**NOTE**: If an issue occurs during the "check" step of the macro, -the build halts. diff --git a/docs/3_Developer_Guides/3_Using_the_CMAKE_Applications_Module /7_Advanced_Customization.md b/docs/3_Developer_Guides/3_Using_the_CMAKE_Applications_Module /7_Advanced_Customization.md deleted file mode 100644 index 88f8c15..0000000 --- a/docs/3_Developer_Guides/3_Using_the_CMAKE_Applications_Module /7_Advanced_Customization.md +++ /dev/null @@ -1,123 +0,0 @@ ---- -edit_link: '' -title: Advanced Customization -origin_url: >- -

-## Including Additional CMake Files - -You can include machine and system custom CMake files and -operating system custom CMake files. - -### Machine and System Custom CMake Files - -Advanced configuration is possible by automatically including -additional CMake files from specific locations. -Following are the locations from which you can add CMake -files. -Inclusions occur in the order shown here: - -- `<project-root-path>/conf.d/app-templates/cmake/cmake.d` - normally located CMake project files -- `$HOME/.config/app-templates/cmake.d` - the home location -- `/etc/app-templates/cmake.d` - the system location - -The CMake files you include must be named using either of the following conventions: - -- `XX-common*.cmake` -- `XX-${PROJECT_NAME}*.cmake` - -In both formats, `XX` are numbers and indicate the order in which the file -is included. -The `*` character represents the filename. - -When naming the file, consider the projects in which the file needs to be -included. -If you want to include the file in all projects, use the keyword `common`. -If you want to include the file in a specific project, use the `${PROJECT_NAME}` -value. - -For example, if you want a CMake file whose name is `my_custom_file` -included first and you want it included in all projects, name the file -`01-common-my_custom_file.cmake`. -If you want the same file included in a single project defined by the -`PROJECT_NAME` variable, and you want it included after all other files, -name the file `99-${PROJECT_NAME}-my_custom_file.cmake`. - -When you include CMake files that use CMake variables, the values override -variables with the same name. -The exception to this rule is if you use a cached variable. -Following is an example: - -```cmake -set(VARIABLE_NAME 'value string random' CACHE STRING 'docstring') -``` - -In this example, the `VARIABLE_NAME` variable is defined as a cached -variable by using the **CACHE** keyword. -Consequently, `VARIABLE_NAME` does not get overridden as a result of -including a CMake file that sets the same variable. - -### Operating System Custom CMake Files - -Including custom CMake files based on the operating system -lets you personalize a project depending on the operating system -you are using. - -At the end of the `config.cmake` file `common.cmake` includes -CMake files to customize your project build depending on your platform. -The operating system is detected by using `/etc/os-release`, -which is the default method used in almost all Linux distributions. -Consequently, you can use the value of field **ID_LIKE** to -add a CMake file for that distribution. -The file comes from your `conf.d/cmake/` directory or relatively -from your `app-templates` submodule path `app-templates/../cmake/`. - -**NOTE:** If the **ID_LIKE** field does not exist, you can use the -**ID** field. - -Files that you add must be named according to the following file naming -convention: - -- `XX-${OSRELEASE}*.cmake` - -In the naming convention, `XX` represents numbers and is the order in which -you want a file included. -The ${OSRELEASE} value is taken from either the **ID_LIKE** or **ID** field -of the `/etc/os-release` file. - -You can also configure a CMake file to be included in cases where no -specific operating system can be found. -To do so, name your CMake file as follows: - -- `XX-default*.cmake` - -A good use case example for these two naming conventions is when you have -a several Linux distributions and all but one can use the same module. -For that case, name one CMake file using the `${OSRELEASE}` value and -name the CMake file to be used with the other distributions using -the `XX-default*.cmake` method. - -## Including Custom Template Scripts - -You can include your own custom template scripts that are passed to the -CMake command `configure_file`. - -Just create your own script and place it in either of the following directories: - -- `$HOME/.config/app-templates/scripts` - the home location -- `/etc/app-templates/scripts` - the system location - -Scripts only need to use the extension `.in` to be parsed and configured by -CMake. diff --git a/docs/3_Developer_Guides/3_Using_the_CMAKE_Applications_Module /8_Autobuild.md b/docs/3_Developer_Guides/3_Using_the_CMAKE_Applications_Module /8_Autobuild.md deleted file mode 100644 index 6c02d1b..0000000 --- a/docs/3_Developer_Guides/3_Using_the_CMAKE_Applications_Module /8_Autobuild.md +++ /dev/null @@ -1,159 +0,0 @@ ---- -edit_link: '' -title: Autobuild -origin_url: >- -

-The **autobuild** script can be invoked from any directory -with all paths considered to be relative to the -script's location. -For makefile scripts, this is the usual behavior. -For Bash scripts, a `cd $(dirname $0)` command must be run at -the beginning of the script. - -At build time, the following calls must be made in the following order: - -1. Initialize the build environment (e.g if the application uses - `cmake` the configure step runs CMake). - - ```bash - autobuild/agl/autobuild configure CONFIGURE_ARGS="..." - ``` - -2. Build the application (i.e. compile, link binaries, assembles javascript, - and so forth). - - ```bash - autobuild/agl/autobuild build BUILD_ARGS="...." - ``` - -3.

-Note that `aglwgt.bbclass` only will use the **package-{coverage,test}** targets (and thus the **build-{coverage,test}**, etc. targets) for service bindings by default, so **autobuild** scripts for applications may omit support for those. - -Specifying the following variables lets you modify compilation behavior: - -- **CLEAN_ARGS**: Variable used at **clean** time. -- **CONFIGURE_ARGS**: Variable used at **configure** time. -- **BUILD_ARGS**: Variable used at **build** time. -- **BUILD_DIR**: Build directory for release type build. - The default value is a "build" directory in the root of the project. -- **BUILD_DIR_DEBUG**: Build directory for debug type build. - The default value is a "build-debug" directory in the root of the project. -- **BUILD_DIR_TEST**: Build directory for test type build. - The default value is a "build-test" directory in the root of the project. -- **BUILD_DIR_COVERAGE**: Build directory for coverage type build. - The default value is a "build-coverage" directory in the root of the project. -- **DEST**: Directory in which to place the created ***wgt*** file(s). - The default directory is the build root directory. - -Note that the values of **BUILD_DIR_{DEBUG,TEST,COVERAGE}** are defined based on the value of **BUILD_DIR**, so this needs to be kept in mind if over-riding it and building those other widget types. - -When you provide a variable, use the CMake format (i.e. -BUILD_ARGS="-DC_FLAGS='-g -O2'"). -Following is an example: - -```bash -./autobuild/agl/autobuild package DEST=/tmp -``` diff --git a/docs/3_Developer_Guides/4_AppFW_-_Privileges_Management/03-AGL-AppFW-Privileges-Management.pdf b/docs/3_Developer_Guides/4_AppFW_-_Privileges_Management/03-AGL-AppFW-Privileges-Management.pdf Binary files differdeleted file mode 100644 index d468610..0000000 --- a/docs/3_Developer_Guides/4_AppFW_-_Privileges_Management/03-AGL-AppFW-Privileges-Management.pdf +++ /dev/null diff --git a/docs/3_Developer_Guides/4_AppFW_-_Privileges_Management/3.5_AppFW_-_Privileges_Management.md b/docs/3_Developer_Guides/4_AppFW_-_Privileges_Management/3.5_AppFW_-_Privileges_Management.md deleted file mode 100644 index a467085..0000000 --- a/docs/3_Developer_Guides/4_AppFW_-_Privileges_Management/3.5_AppFW_-_Privileges_Management.md +++ /dev/null @@ -1 +0,0 @@ -[**3.5 AppFW -

Each action returns a status -where 0=success and 1=failure. - -* **AppFw API** provides a generic model to request other bindings. Requested bindings can be local (eg: ALSA/UCM) or external (eg: vehicle signalling). - * `"action": "api://API_NAME#verb_name"` -* C-API, when defined in the onload section, the plugin may provide C native API with `CTLP-CAPI(apiname, uid, args, query, context)`. Plugin may also create Lua command with `CTLP-LUA2C(LuaFuncName, uid, args, query, context)`. Where `args`+`query` are JSON-C object and context is the returned value from `CTLP_ONLOAD` function. Any missing value is set to NULL. - * `"action": "plugin://plugin_name#function_name"` -* Lua-API, when compiled with Lua option, the controller supports action defined directly in Lua script. During "*onload*" phase, the controller searches in `CONTROL_LUA_PATH` file with pattern "(prefix-)bindermiddlename*.lua". Any file corresponding to this pattern is automatically loaded. Any function defined in those Lua scripts can be called through a controller action. Lua functions receive three parameters (uid, args, query). - * `"action": "lua://plugin_name#function_name"` - -You also can add the **privileges** property that handles AGL permission -needed to be able to call this action. - -> **Note**: Lua added functions are systematically prefixed. AGL standard AppFw -functions are prefixed with AGL: (eg: AFB:notice(), AFB:success(), ...). -> User Lua functions added through the plugin and CTLP_LUA2C are prefixed with -the plugin uid or the one you defined in your config (eg: MyPlug:HelloWorld1). - -## Available Application Framework Commands - -Each Lua AppFw commands should be prefixed by AFB: - -* `AFB:notice ("format", arg1,... argn)` directly printed LUA tables as json string with '%s'. - `AFB:error`, `AFB:warning`, `AFB:info`, `AFB:debug` work on the same model. Printed messages are limited to 512 characters. - -* `AFB:service ('API', 'VERB', {query}, "Lua_Callback_Name", {context})` is an asynchronous call to another binding. When empty, query/context should be set to '{}' - and not to 'nil'. When 'nil', Lua does not send 'NULL' value but removes arguments to calling stack. WARNING:"Callback" - is the name of the callback as a string and not a pointer to the callback. (If someone as a solution to fix this, please - let me known). Callback is call as LUA "function Alsa_Get_Hal_CB (error, result, context)" where: - * error is a Boolean - * result is the full answer from AppFw (do not forget to extract the response) - * context is a copy of the Lua table pass as an argument (warning it's a copy not a pointer to original table) - -* `error,result=AFB:servsync('API', 'VERB', {query})` is saved as previous but for synchronous call. Note that Lua accepts multiple - returns. AFB:servsync returns both the error message and the response as a Lua table. Like for AFB:service, the user should not - forget to extract response from result. - -* `AFB:success(request, response)` is the success request. request is the opaque handle passes when Lua is called from (api="control", verb="docall"). - Response is a Lua table that will be returned to the client. - -* `AFB:fail(request, response)` is the same as for success. Note that LUA generates automatically the error code from Lua function name. - The response is transformed into a json string before being returned to the client. - -* `EventHandle=AFB:evtmake("MyEventName")` creates an event and returns the handle as an opaque handle. Note that due to a limitation - of json_object, this opaque handle cannot be passed as an argument in a callback context. - -* `AFB:subscribe(request, MyEventHandle)` subscribes a given client to a previously created event. - -* `AFB:evtpush (MyEventHandle, MyEventData)` pushes an event to every subscribed client. MyEventData is a Lua table that will be - sent as a json object to the corresponding clients. - -* `timerHandle=AFB:timerset (MyTimer, "Timer_Test_CB", context)` initialises a timer from MyTimer Lua table. This table should contains 3 elements: - MyTimer={[l"abel"]="MyTimerName", ["delay"]=timeoutInMs, ["count"]=nBOfCycles}. Note that if count==0 then timer is cycled - infinitely. Context is a standard Lua table. This function returns an opaque handle to be used to further control the timer. - -* `AFB:timerclear(timerHandle)` kills an existing timer. Returns an error when timer does not exit. - -* `MyTimer=AFB:timerget(timerHandle)` returns uid, delay and count of an active timer. Returns an error when timerHandle does not - point on an active timer. - -* `AFB:GetEventLoop()` retrieves the common systemd's event loop of AFB. - -* `AFB:RootDirGetFD()` gets the root directory file descriptor. This file descriptor can be used with functions 'openat', 'fstatat', ... - -> **Note**: Except for functions call during binding initialisation period. Lua calls are protected and should returned clean messages -> even when they are improperly used. 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 a set of Lua commands usable inside any script (onload, control,event). A simple -plugin that provides both notice 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 declared with `CTLP_REGISTER("MyCtlSamplePlugin")`. This entry point defines a special structure that is checked -at plugin load time by the controller. Then you have an optional init routine declare with `CTLP_ONLOAD(plugin, handle)`. - The init routine may create -a plugin context that is later presented to every plugin API, this for both LUA and native C ones. Then each: - -* C API declare with `CTLP_CAPI(MyCFunction, source, argsJ, queryJ) {your code}`. Where: - * **MyFunction** is your function - * **source** is the structure config - * **argsJ** a json_object containing the argument attaches to this control in JSON config file - * **queryJ** a json_object - -* Lua API declare with `CTLP_LUA2C(MyLuaCFunction, source, argsJ, responseJ) {your code}`. Where - * **MyLuaCFunction** is both the name of your C function and Lua command - * **source** is the structure config - * **argsJ** the arguments passed this time from Lua script and not from Json config file. - * **responseJ** if success the argument is passed into the request. - -> **Warning**: Lua samples use with controller enforce strict mode. As a result every variable should be declared 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 prefixed by '_'. -> Note that LUA requires an initialisation value for every variables and declaring something like "local myvar" will not -> allocate "myvar". - -## Debugging Facilities - -Controller Lua scripts are checked for syntax from CMAKE template with Luac. When needed to go further, a developer API should be allowed to -execute directly Lua commands within the 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 parameters. When funcname is not given by default, the controller tries to execute middle filename doscript-xxxx-????.lua. - -When executed from the controller, Lua script may use any AppFw Apis as well as any L2C user defines commands in plugin. - -## Running as Standalone Controller - -The controller is a standard binding. It can be started with the following command: - -```bash -afb-daemon --name=yourname --port=1234 --workdir=. --roothttp=./htdocs --tracereq=common --token= --verbose --binding=pathtoyourbinding.so --monitoring -``` - -Afb-Daemon only loads controller bindings without searching for the other -binding. In this case, the controller binding will search for a configuration file -name '(prefix-)bindermiddlename*.json'. This model can be used to implement for testing -purpose or simply to act as the glue between a UI and other binder/services. diff --git a/docs/3_Developer_Guides/5_Controller_Guides/3.6.3_Usage.md b/docs/3_Developer_Guides/5_Controller_Guides/3.6.3_Usage.md deleted file mode 100644 index b28d8b2..0000000 --- a/docs/3_Developer_Guides/5_Controller_Guides/3.6.3_Usage.md +++ /dev/null @@ -1,196 +0,0 @@ ---- -edit_link: '' -title: Usage -origin_url: >- - https://git.automotivelinux.org/src/libappcontroller/plain/docs/Usage.md?h=master ---- - -<!-- WARNING: This file is generated by fetch_docs.js using /home/boron/Documents/AGL/docs-webtemplate/site/_data/tocs/devguides/master/libappcontroller-guides-devguides-book.yml --> - -# Usage - -## Add libappcontroller as a static library to your binding - -In your `config.cmake` file, add a dependency to the controller library, i.e: - -```cmake -set(PKG_REQUIRED_LIST - json-c - afb-daemon - appcontroller --> this is the controller library dependency name. -) -``` - -Or you can also use the [FIND_PACKAGE](https://cmake.org/cmake/help/v3.6/command/find_package.html?highlight=find_package) -CMake command to add it. - -## Declare your controller config section in your binding - -```C -// CtlSectionT syntax: -// key: "section name in config file" -// loadCB: callback to process section -// handle: a void* pass to callback when processing section -static CtlSectionT ctlSections[]= { - {.key="plugins" , .loadCB= PluginConfig, .handle= &halCallbacks}, - {.key="onload" , .loadCB= OnloadConfig}, - {.key="halmap" , .loadCB= MapConfigLoad}, - {.key=NULL} -}; - -``` - -## Do the controller config parsing at binding pre-init - -```C - // check if config file exist - const char *dirList= getenv("CTL_CONFIG_PATH"); - if (!dirList) dirList=CONTROL_CONFIG_PATH; - - const char *configPath = CtlConfigSearch(apiHandle, dirList, "prefix"); - if(!confiPath) return -1; - - ctlConfig = CtlConfigLoad(dirList, ctlSections); - if (!ctlConfig) return -1; -``` - -## Execute the controller config during binding init - -```C - int err = CtlConfigExec (ctlConfig); -``` - -## (Optional) Migrate from the git submodule version - -### Remove the git submodule version - -If you already use the controller component but use the submodule version then -you have to get rid of it to be sure to link and use the library version.

Our class had these design goals: - -- **Intuitive syntax**. In languages such as Python, JSON feels like a first class data type. We used all the operator magic of modern C++ to achieve the same feeling in your code. Check out the [examples below](#examples) and you'll know what I mean. - -- **Trivial integration**. Our whole code consists of a single header file [`json.hpp`](https://github.com/nlohmann/json/blob/develop/src/json.hpp). That's it. No library, no subproject, no dependencies, no complex build system. The class is written in vanilla C++11. All in all, everything should require no adjustment of your compiler flags or project settings. - -- **Serious testing**. Our class is heavily [unit-tested](https://github.com/nlohmann/json/blob/master/test/src/unit.cpp) and covers [100%](https://coveralls.io/r/nlohmann/json) of the code, including all exceptional behavior. Furthermore, we checked with [Valgrind](http://valgrind.org) that there are no memory leaks. To maintain high quality, the project is following the [Core Infrastructure Initiative (CII) best practices](https://bestpractices.coreinfrastructure.org/projects/289). - -Other aspects were not so important to us: - -- **Memory efficiency**. Each JSON object has an overhead of one pointer (the maximal size of a union) and one enumeration element (1 byte). The default generalization uses the following C++ data types: `std::string` for strings, `int64_t`, `uint64_t` or `double` for numbers, `std::map` for objects, `std::vector` for arrays, and `bool` for Booleans. However, you can template the generalized class `basic_json` to your needs. - -- **Speed**. There are certainly [faster JSON libraries](https://github.com/miloyip/nativejson-benchmark#parsing-time) out there. However, if your goal is to speed up your development by adding JSON support with a single header, then this library is the way to go. If you know how to use a `std::vector` or `std::map`, you are already set. - -See the [contribution guidelines](https://github.com/nlohmann/json/blob/master/.github/CONTRIBUTING.md#please-dont) for more information. - -## Integration - -The single required source, file `json.hpp` is in the `src` directory or [released here](https://github.com/nlohmann/json/releases). All you need to do is add - -```cpp -#include "json.hpp" - -// for convenience -using json = nlohmann::json; -``` - -to the files you want to use JSON objects. That's it. Do not forget to set the necessary switches to enable C++11 (e.g., `-std=c++11` for GCC and Clang). - -:beer: If you are using OS X and [Homebrew](http://brew.sh), just type `brew tap nlohmann/json` and `brew install nlohmann_json` and you're set. If you want the bleeding edge rather than the latest release, use `brew install nlohmann_json --HEAD`. - -If you are using the [Meson Build System](http://mesonbuild.com), then you can wrap this repo as a subproject. - -If you are using [Conan](https://www.conan.io/) to manage your dependencies, merely add `jsonformoderncpp/x.y.z@vthiery/stable` to your `conanfile.py`'s requires, where `x.y.z` is the release version you want to use. Please file issues [here](https://github.com/vthiery/conan-jsonformoderncpp/issues) if you experience problems with the packages. - -If you are using [hunter](https://github.com/ruslo/hunter/) on your project for external dependencies, then you can use the [nlohman_json package](https://github.com/ruslo/hunter/wiki/pkg.nlohmann_json). Please see the hunter project for any issues regarding the packaging. - -:warning: [Version 3.0.0](https://github.com/nlohmann/json/wiki/Road-toward-3.0.0) is currently under development. Branch `develop` is used for the ongoing work and is probably **unstable**. Please use the `master` branch for the last stable version 2.1.1. - -## Examples - -Beside the examples below, you may want to check the [documentation](https://nlohmann.github.io/json/) where each function contains a separate code example (e.g., check out [`emplace()`](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_a602f275f0359ab181221384989810604.html#a602f275f0359ab181221384989810604)). All [example files](https://github.com/nlohmann/json/tree/develop/doc/examples) can be compiled and executed on their own (e.g., file [emplace.cpp](https://github.com/nlohmann/json/blob/develop/doc/examples/emplace.cpp)). - -### JSON as first-class data type - -Here are some examples to give you an idea how to use the class. - -Assume you want to create the JSON object - -```json -{ - "pi": 3.141, - "happy": true, - "name": "Niels", - "nothing": null, - "answer": { - "everything": 42 - }, - "list": [1, 0, 2], - "object": { - "currency": "USD", - "value": 42.99 - } -} -``` - -With the JSON class, you could write: - -```cpp -// create an empty structure (null) -json j; - -// add a number that is stored as double (note the implicit conversion of j to an object) -j["pi"] = 3.141; - -// add a Boolean that is stored as bool -j["happy"] = true; - -// add a string that is stored as std::string -j["name"] = "Niels"; - -// add another null object by passing nullptr -j["nothing"] = nullptr; - -// add an object inside the object -j["answer"]["everything"] = 42; - -// add an array that is stored as std::vector (using an initializer list) -j["list"] = { 1, 0, 2 }; - -// add another object (using an initializer list of pairs) -j["object"] = { {"currency", "USD"}, {"value", 42.99} }; - -// instead, you could also write (which looks very similar to the JSON above) -json j2 = { - {"pi", 3.141}, - {"happy", true}, - {"name", "Niels"}, - {"nothing", nullptr}, - {"answer", { - {"everything", 42} - }}, - {"list", {1, 0, 2}}, - {"object", { - {"currency", "USD"}, - {"value", 42.99} - }} -}; -``` - -Note that in all these cases, you never need to "tell" the compiler which JSON value you want to use. If you want to be explicit or express some edge cases, the functions `json::array` and `json::object` will help: - -```cpp -// a way to express the empty array [] -json empty_array_explicit = json::array(); - -// ways to express the empty object {} -json empty_object_implicit = json({}); -json empty_object_explicit = json::object(); - -// a way to express an _array_ of key/value pairs [["currency", "USD"], ["value", 42.99]] -json array_not_object = { json::array({"currency", "USD"}), json::array({"value", 42.99}) }; -``` - -### Serialization / Deserialization - -#### To/from strings - -You can create an object (deserialization) by appending `_json` to a string literal: - -```cpp -// create object from string literal -json j = "{ \"happy\": true, \"pi\": 3.141 }"_json; - -// or even nicer with a raw string literal -auto j2 = R"( - { - "happy": true, - "pi": 3.141 - } -)"_json; -``` - -Note that without appending the `_json` suffix, the passed string literal is not parsed, but just used as JSON string value. That is, `json j = "{ \"happy\": true, \"pi\": 3.141 }"` would just store the string `"{ "happy": true, "pi": 3.141 }"` rather than parsing the actual object. - -The above example can also be expressed explicitly using `json::parse()`: - -```cpp -// parse explicitly -auto j3 = json::parse("{ \"happy\": true, \"pi\": 3.141 }"); -``` - -You can also get a string representation (serialize): - -```cpp -// explicit conversion to string -std::string s = j.dump(); // {\"happy\":true,\"pi\":3.141} - -// serialization with pretty printing -// pass in the amount of spaces to indent -std::cout << j.dump(4) << std::endl; -// { -// "happy": true, -// "pi": 3.141 -// } -``` - -#### To/from streams (e.g. files, string streams) - -You can also use streams to serialize and deserialize: - -```cpp -// deserialize from standard input -json j; -std::cin >> j; - -// serialize to standard output -std::cout << j; - -// the setw manipulator was overloaded to set the indentation for pretty printing -std::cout << std::setw(4) << j << std::endl; -``` - -These operators work for any subclasses of `std::istream` or `std::ostream`. Here is the same example with files: - -```cpp -// read a JSON file -std::ifstream i("file.json"); -json j; -i >> j; - -// write prettified JSON to another file -std::ofstream o("pretty.json"); -o << std::setw(4) << j << std::endl; -``` - -Please note that setting the exception bit for `failbit` is inappropriate for this use case. It will result in program termination due to the `noexcept` specifier in use. - -#### Read from iterator range - -You can also read JSON from an iterator range; that is, from any container accessible by iterators whose content is stored as contiguous byte sequence, for instance a `std::vector<std::uint8_t>`: - -```cpp -std::vector<std::uint8_t> v = {'t', 'r', 'u', 'e'}; -json j = json::parse(v.begin(), v.end()); -``` - -You may leave the iterators for the range [begin, end): - -```cpp -std::vector<std::uint8_t> v = {'t', 'r', 'u', 'e'}; -json j = json::parse(v); -``` - -### STL-like access - -We designed the JSON class to behave just like an STL container. In fact, it satisfies the [**ReversibleContainer**](http://en.cppreference.com/w/cpp/concept/ReversibleContainer) requirement. - -```cpp -// create an array using push_back -json j; -j.push_back("foo"); -j.push_back(1); -j.push_back(true); - -// also use emplace_back -j.emplace_back(1.78); - -// iterate the array -for (json::iterator it = j.begin(); it != j.end(); ++it) { - std::cout << *it << '\n'; -} - -// range-based for -for (auto& element : j) { - std::cout << element << '\n'; -} - -// getter/setter -const std::string tmp = j[0]; -j[1] = 42; -bool foo = j.at(2); - -// comparison -j == "[\"foo\", 1, true]"_json; // true - -// other stuff -j.size(); // 3 entries -j.empty(); // false -j.type(); // json::value_t::array -j.clear(); // the array is empty again - -// convenience type checkers -j.is_null(); -j.is_boolean(); -j.is_number(); -j.is_object(); -j.is_array(); -j.is_string(); - -// create an object -json o; -o["foo"] = 23; -o["bar"] = false; -o["baz"] = 3.141; - -// also use emplace -o.emplace("weather", "sunny"); - -// special iterator member functions for objects -for (json::iterator it = o.begin(); it != o.end(); ++it) { - std::cout << it.key() << " : " << it.value() << "\n"; -} - -// find an entry -if (o.find("foo") != o.end()) { - // there is an entry with key "foo" -} - -// or simpler using count() -int foo_present = o.count("foo"); // 1 -int fob_present = o.count("fob"); // 0 - -// delete an entry -o.erase("foo"); -``` - -### Conversion from STL containers - -Any sequence container (`std::array`, `std::vector`, `std::deque`, `std::forward_list`, `std::list`) whose values can be used to construct JSON types (e.g., integers, floating point numbers, Booleans, string types, or again STL containers described in this section) can be used to create a JSON array. The same holds for similar associative containers (`std::set`, `std::multiset`, `std::unordered_set`, `std::unordered_multiset`), but in these cases the order of the elements of the array depends how the elements are ordered in the respective STL container. - -```cpp -std::vector<int> c_vector {1, 2, 3, 4}; -json j_vec(c_vector); -// [1, 2, 3, 4] - -std::deque<double> c_deque {1.2, 2.3, 3.4, 5.6}; -json j_deque(c_deque); -// [1.2, 2.3, 3.4, 5.6] - -std::list<bool> c_list {true, true, false, true}; -json j_list(c_list); -// [true, true, false, true] - -std::forward_list<int64_t> c_flist {12345678909876, 23456789098765, 34567890987654, 45678909876543}; -json j_flist(c_flist); -// [12345678909876, 23456789098765, 34567890987654, 45678909876543] - -std::array<unsigned long, 4> c_array {{1, 2, 3, 4}}; -json j_array(c_array); -// [1, 2, 3, 4] - -std::set<std::string> c_set {"one", "two", "three", "four", "one"}; -json j_set(c_set); // only one entry for "one" is used -// ["four", "one", "three", "two"] - -std::unordered_set<std::string> c_uset {"one", "two", "three", "four", "one"}; -json j_uset(c_uset); // only one entry for "one" is used -// maybe ["two", "three", "four", "one"] - -std::multiset<std::string> c_mset {"one", "two", "one", "four"}; -json j_mset(c_mset); // both entries for "one" are used -// maybe ["one", "two", "one", "four"] - -std::unordered_multiset<std::string> c_umset {"one", "two", "one", "four"}; -json j_umset(c_umset); // both entries for "one" are used -// maybe ["one", "two", "one", "four"] -``` - -Likewise, any associative key-value containers (`std::map`, `std::multimap`, `std::unordered_map`, `std::unordered_multimap`) whose keys can construct an `std::string` and whose values can be used to construct JSON types (see examples above) can be used to create a JSON object. Note that in case of multimaps only one key is used in the JSON object and the value depends on the internal order of the STL container. - -```cpp -std::map<std::string, int> c_map { {"one", 1}, {"two", 2}, {"three", 3} }; -json j_map(c_map); -// {"one": 1, "three": 3, "two": 2 } - -std::unordered_map<const char*, double> c_umap { {"one", 1.2}, {"two", 2.3}, {"three", 3.4} }; -json j_umap(c_umap); -// {"one": 1.2, "two": 2.3, "three": 3.4} - -std::multimap<std::string, bool> c_mmap { {"one", true}, {"two", true}, {"three", false}, {"three", true} }; -json j_mmap(c_mmap); // only one entry for key "three" is used -// maybe {"one": true, "two": true, "three": true} - -std::unordered_multimap<std::string, bool> c_ummap { {"one", true}, {"two", true}, {"three", false}, {"three", true} }; -json j_ummap(c_ummap); // only one entry for key "three" is used -// maybe {"one": true, "two": true, "three": true} -``` - -### JSON Pointer and JSON Patch - -The library supports **JSON Pointer** ([RFC 6901](https://tools.ietf.org/html/rfc6901)) as alternative means to address structured values. On top of this, **JSON Patch** ([RFC 6902](https://tools.ietf.org/html/rfc6902)) allows to describe differences between two JSON values - effectively allowing patch and diff operations known from Unix. - -```cpp -// a JSON value -json j_original = R"({ - "baz": ["one", "two", "three"], - "foo": "bar" -})"_json; - -// access members with a JSON pointer (RFC 6901) -j_original["/baz/1"_json_pointer]; -// "two" - -// a JSON patch (RFC 6902) -json j_patch = R"([ - { "op": "replace", "path": "/baz", "value": "boo" }, - { "op": "add", "path": "/hello", "value": ["world"] }, - { "op": "remove", "path": "/foo"} -])"_json; - -// apply the patch -json j_result = j_original.patch(j_patch); -// { -// "baz": "boo", -// "hello": ["world"] -// } - -// calculate a JSON patch from two JSON values -json::diff(j_result, j_original); -// [ -// { "op":" replace", "path": "/baz", "value": ["one", "two", "three"] }, -// { "op": "remove","path": "/hello" }, -// { "op": "add", "path": "/foo", "value": "bar" } -// ] -``` - -### Implicit conversions - -The type of the JSON object is determined automatically by the expression to store. Likewise, the stored value is implicitly converted. - -```cpp -// strings -std::string s1 = "Hello, world!"; -json js = s1; -std::string s2 = js; - -// Booleans -bool b1 = true; -json jb = b1; -bool b2 = jb; - -// numbers -int i = 42; -json jn = i; -double f = jn; - -// etc. -``` - -You can also explicitly ask for the value: - -```cpp -std::string vs = js.get<std::string>(); -bool vb = jb.get<bool>(); -int vi = jn.get<int>(); - -// etc. -``` - -### Arbitrary types conversions - -Every type can be serialized in JSON, not just STL-containers and scalar types. Usually, you would do something along those lines: - -```cpp -namespace ns { - // a simple struct to model a person - struct person { - std::string name; - std::string address; - int age; - }; -} - -ns::person p = {"Ned Flanders", "744 Evergreen Terrace", 60}; - -// convert to JSON: copy each value into the JSON object -json j; -j["name"] = p.name; -j["address"] = p.address; -j["age"] = p.age; - -// ... - -// convert from JSON: copy each value from the JSON object -ns::person p { - j["name"].get<std::string>(), - j["address"].get<std::string>(), - j["age"].get<int>() -}; -``` - -It works, but that's quite a lot of boilerplate... Fortunately, there's a better way: - -```cpp -// create a person -ns::person p {"Ned Flanders", "744 Evergreen Terrace", 60}; - -// conversion: person -> json -json j = p; - -std::cout << j << std::endl; -// {"address":"744 Evergreen Terrace","age":60,"name":"Ned Flanders"} - -// conversion: json -> person -ns::person p2 = j; - -// that's it -assert(p == p2); -``` - -#### Basic usage - -To make this work with one of your types, you only need to provide two functions: - -```cpp -using nlohmann::json; - -namespace ns { - void to_json(json& j, const person& p) { - j = json{ {"name", p.name}, {"address", p.address}, {"age", p.age} }; - } - - void from_json(const json& j, person& p) { - p.name = j.at("name").get<std::string>(); - p.address = j.at("address").get<std::string>(); - p.age = j.at("age").get<int>(); - } -} // namespace ns -``` - -That's all! When calling the `json` constructor with your type, your custom `to_json` method will be automatically called. -Likewise, when calling `get<your_type>()`, the `from_json` method will be called. - -Some important things: - -- Those methods **MUST** be in your type's namespace (which can be the global namespace), or the library will not be able to locate them (in this example, they are in namespace `ns`, where `person` is defined). -- When using `get<your_type>()`, `your_type` **MUST** be [DefaultConstructible](http://en.cppreference.com/w/cpp/concept/DefaultConstructible). (There is a way to bypass this requirement described later.) -- In function `from_json`, use function [`at()`](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_a93403e803947b86f4da2d1fb3345cf2c.html#a93403e803947b86f4da2d1fb3345cf2c) to access the object values rather than `operator[]`. In case a key does not exists, `at` throws an exception that you can handle, whereas `operator[]` exhibits undefined behavior. -- In case your type contains several `operator=` definitions, code like `your_variable = your_json;` [may not compile](https://github.com/nlohmann/json/issues/667). You need to write `your_variable = your_json.get<decltype your_variable>();` instead. -- You do not need to add serializers or deserializers for STL types like `std::vector`: the library already implements these. - -#### How do I convert third-party types? - -This requires a bit more advanced technique. But first, let's see how this conversion mechanism works: - -The library uses **JSON Serializers** to convert types to json. -The default serializer for `nlohmann::json` is `nlohmann::adl_serializer` (ADL means [Argument-Dependent Lookup](http://en.cppreference.com/w/cpp/language/adl)). - -It is implemented like this (simplified): - -```cpp -template <typename T> -struct adl_serializer { - static void to_json(json& j, const T& value) { - // calls the "to_json" method in T's namespace - } - - static void from_json(const json& j, T& value) { - // same thing, but with the "from_json" method - } -}; -``` - -This serializer works fine when you have control over the type's namespace. However, what about `boost::optional`, or `std::filesystem::path` (C++17)? Hijacking the `boost` namespace is pretty bad, and it's illegal to add something other than template specializations to `std`... - -To solve this, you need to add a specialization of `adl_serializer` to the `nlohmann` namespace, here's an example: - -```cpp -// partial specialization (full specialization works too) -namespace nlohmann { - template <typename T> - struct adl_serializer<boost::optional<T>> { - static void to_json(json& j, const boost::optional<T>& opt) { - if (opt == boost::none) { - j = nullptr; - } else { - j = *opt; // this will call adl_serializer<T>::to_json which will - // find the free function to_json in T's namespace! - } - } - - static void from_json(const json& j, boost::optional<T>& opt) { - if (j.is_null()) { - opt = boost::none; - } else { - opt = j.get<T>(); // same as above, but with - // adl_serializer<T>::from_json - } - } - }; -} -``` - -#### How can I use `get()` for non-default constructible/non-copyable types? - -There is a way, if your type is [MoveConstructible](http://en.cppreference.com/w/cpp/concept/MoveConstructible). You will need to specialize the `adl_serializer` as well, but with a special `from_json` overload: - -```cpp -struct move_only_type { - move_only_type() = delete; - move_only_type(int ii): i(ii) {} - move_only_type(const move_only_type&) = delete; - move_only_type(move_only_type&&) = default; - - int i; -}; - -namespace nlohmann { - template <> - struct adl_serializer<move_only_type> { - // note: the return type is no longer 'void', and the method only takes - // one argument - static move_only_type from_json(const json& j) { - return {j.get<int>()}; - } - - // Here's the catch! You must provide a to_json method! Otherwise you - // will not be able to convert move_only_type to json, since you fully - // specialized adl_serializer on that type - static void to_json(json& j, move_only_type t) { - j = t.i; - } - }; -} -``` - -#### Can I write my own serializer? (Advanced use) - -Yes. You might want to take a look at [`unit-udt.cpp`](https://github.com/nlohmann/json/blob/develop/test/src/unit-udt.cpp) in the test suite, to see a few examples. - -If you write your own serializer, you'll need to do a few things: - -- use a different `basic_json` alias than `nlohmann::json` (the last template parameter of `basic_json` is the `JSONSerializer`) -- use your `basic_json` alias (or a template parameter) in all your `to_json`/`from_json` methods -- use `nlohmann::to_json` and `nlohmann::from_json` when you need ADL - -Here is an example, without simplifications, that only accepts types with a size <= 32, and uses ADL. - -```cpp -// You should use void as a second template argument -// if you don't need compile-time checks on T -template<typename T, typename SFINAE = typename std::enable_if<sizeof(T) <= 32>::type> -struct less_than_32_serializer { - template <typename BasicJsonType> - static void to_json(BasicJsonType& j, T value) { - // we want to use ADL, and call the correct to_json overload - using nlohmann::to_json; // this method is called by adl_serializer, - // this is where the magic happens - to_json(j, value); - } - - template <typename BasicJsonType> - static void from_json(const BasicJsonType& j, T& value) { - // same thing here - using nlohmann::from_json; - from_json(j, value); - } -}; -``` - -Be **very** careful when reimplementing your serializer, you can stack overflow if you don't pay attention: - -```cpp -template <typename T, void> -struct bad_serializer -{ - template <typename BasicJsonType> - static void to_json(BasicJsonType& j, const T& value) { - // this calls BasicJsonType::json_serializer<T>::to_json(j, value); - // if BasicJsonType::json_serializer == bad_serializer ... oops! - j = value; - } - - template <typename BasicJsonType> - static void to_json(const BasicJsonType& j, T& value) { - // this calls BasicJsonType::json_serializer<T>::from_json(j, value); - // if BasicJsonType::json_serializer == bad_serializer ... oops! - value = j.template get<T>(); // oops! - } -}; -``` - -### Binary formats (CBOR and MessagePack) - -Though JSON is a ubiquitous data format, it is not a very compact format suitable for data exchange, for instance over a network. Hence, the library supports [CBOR](http://cbor.io) (Concise Binary Object Representation) and [MessagePack](http://msgpack.org) to efficiently encode JSON values to byte vectors and to decode such vectors. - -```cpp -// create a JSON value -json j = R"({"compact": true, "schema": 0})"_json; - -// serialize to CBOR -std::vector<std::uint8_t> v_cbor = json::to_cbor(j); - -// 0xa2, 0x67, 0x63, 0x6f, 0x6d, 0x70, 0x61, 0x63, 0x74, 0xf5, 0x66, 0x73, 0x63, 0x68, 0x65, 0x6d, 0x61, 0x00 - -// roundtrip -json j_from_cbor = json::from_cbor(v_cbor); - -// serialize to MessagePack -std::vector<std::uint8_t> v_msgpack = json::to_msgpack(j); - -// 0x82, 0xa7, 0x63, 0x6f, 0x6d, 0x70, 0x61, 0x63, 0x74, 0xc3, 0xa6, 0x73, 0x63, 0x68, 0x65, 0x6d, 0x61, 0x00 - -// roundtrip -json j_from_msgpack = json::from_msgpack(v_msgpack); -``` - -## Supported compilers - -Though it's 2016 already, the support for C++11 is still a bit sparse. Currently, the following compilers are known to work: - -- GCC 4.9 - 7.1 (and possibly later) -- Clang 3.4 - 5.0 (and possibly later) -- Microsoft Visual C++ 2015 / Build Tools 14.0.25123.0 (and possibly later) -- Microsoft Visual C++ 2017 / Build Tools 15.1.548.43366 (and possibly later) - -I would be happy to learn about other compilers/versions. - -Please note: - -- GCC 4.8 does not work because of two bugs ([55817](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=55817) and [57824](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57824)) in the C++11 support. Note there is a [pull request](https://github.com/nlohmann/json/pull/212) to fix some of the issues. -- Android defaults to using very old compilers and C++ libraries. To fix this, add the following to your `Application.mk`. This will switch to the LLVM C++ library, the Clang compiler, and enable C++11 and other features disabled by default. - -```bb - APP_STL := c++_shared - NDK_TOOLCHAIN_VERSION := clang3.6 - APP_CPPFLAGS += -frtti -fexceptions -``` - -The code compiles successfully with [Android NDK](https://developer.android.com/ndk/index.html?hl=ml), Revision 9 - 11 (and possibly later) and [CrystaX's Android NDK](https://www.crystax.net/en/android/ndk) version 10. - -- For GCC running on MinGW or Android SDK, the error `'to_string' is not a member of 'std'` (or similarly, for `strtod`) may occur.

In particular, note [`operator[]`](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_a2e26bd0b0168abb61f67ad5bcd5b9fa1.html#a2e26bd0b0168abb61f67ad5bcd5b9fa1) implements **unchecked access** for const objects: If the given key is not present, the behavior is undefined (think of a dereferenced null pointer) and yields an [assertion failure](https://github.com/nlohmann/json/issues/289) if assertions are switched on. If you are not sure whether an element in an object exists, use checked access with the [`at()` function](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_a674de1ee73e6bf4843fc5dc1351fb726.html#a674de1ee73e6bf4843fc5dc1351fb726). -- As the exact type of a number is not defined in the [JSON specification](http://rfc7159.net/rfc7159), this library tries to choose the best fitting C++ number type automatically. As a result, the type `double` may be used to store numbers which may yield [**floating-point exceptions**](https://github.com/nlohmann/json/issues/181) in certain rare situations if floating-point exceptions have been unmasked in the calling code. These exceptions are not caused by the library and need to be fixed in the calling code, such as by re-masking the exceptions prior to calling library functions. -- The library supports **Unicode input** as follows: - - Only **UTF-8** encoded input is supported which is the default encoding for JSON according to [RFC 7159](http://rfc7159.net/rfc7159#rfc.section.8.1). - - Other encodings such as Latin-1, UTF-16, or UTF-32 are not supported and will yield parse errors. - - [Unicode noncharacters](http://www.unicode.org/faq/private_use.html#nonchar1) will not be replaced by the library. - - Invalid surrogates (e.g., incomplete pairs such as `\uDEAD`) will yield parse errors. - - The strings stored in the library are UTF-8 encoded. When using the default string type (`std::string`), note that its length/size functions return the number of stored bytes rather than the number of characters or glyphs. -- The code can be compiled without C++ **runtime type identification** features; that is, you can use the `-fno-rtti` compiler flag. -- **Exceptions** are used widely within the library. They can, however, be switched off with either using the compiler flag `-fno-exceptions` or by defining the symbol `JSON_NOEXCEPTION`. In this case, exceptions are replaced by an `abort()` call. -- By default, the library does not preserve the **insertion order of object elements**. This is standards-compliant, as the [JSON standard](https://tools.ietf.org/html/rfc7159.html) defines objects as "an unordered collection of zero or more name/value pairs". If you do want to preserve the insertion order, you can specialize the object type with containers like [`tsl::ordered_map`](https://github.com/Tessil/ordered-map) or [`nlohmann::fifo_map`](https://github.com/nlohmann/fifo_map). - -## Execute unit tests - -To compile and run the tests, you need to execute - -```sh -$ make json_unit -Ctest -$ ./test/json_unit "*" - -=============================================================================== -All tests passed (14504461 assertions in 48 test cases) -``` - -Alternatively, you can use [CMake](https://cmake.org) and run - -```sh -mkdir build -cd build -cmake .. -make -ctest -``` - -For more information, have a look at the file [.travis.yml](https://github.com/nlohmann/json/blob/master/.travis.yml). diff --git a/docs/3_Developer_Guides/6_AFB_Helper_Guide/3.7.8_C_JSON_Wrapper.md b/docs/3_Developer_Guides/6_AFB_Helper_Guide/3.7.8_C_JSON_Wrapper.md deleted file mode 100644 index e236248..0000000 --- a/docs/3_Developer_Guides/6_AFB_Helper_Guide/3.7.8_C_JSON_Wrapper.md +++ /dev/null @@ -1,344 +0,0 @@ ---- -edit_link: '' -title: C JSON Wrapper -origin_url: >- - https://git.automotivelinux.org/src/libafb-helpers/plain/docs/wrap-json.md?h=master ---- - -<!-- WARNING: This file is generated by fetch_docs.js using /home/boron/Documents/AGL/docs-webtemplate/site/_data/tocs/devguides/master/afb-helpers-function-references-afb-helpers-book.yml --> - -WRAP-JSON facility -================== - -The facility wrap-json is based on the pack/unpack API on the -library jansson.

Value building is -based on a *format string* that is used to tell the functions about the -expected arguments. - -For example, the format string `"i"` specifies a single integer value, -while the format string `"[ssb]"` or the equivalent `"[s, s, b]"` -specifies an array value with two strings and a boolean as its items: - - /* Create the JSON integer 42 */ - wrap_json_pack(&result, "i", 42); - - /* Create the JSON array ["foo", "bar", true] */ - wrap_json_pack(&result, "[ssb]", "foo", "bar", 1); - -Here's the full list of format specifiers. The type in parentheses -denotes the resulting JSON type, and the type in brackets (if any) -denotes the C type that is expected as the corresponding argument or -arguments. - -`s` (string) \[const char \*\] - -: Convert a null terminated UTF-8 string to a JSON string. - -`s?` (string) \[const char \*\] - -: Like `s`, but if the argument is *NULL*, output a JSON null value. - -`s*` (string) \[const char \*\] - -: Like `s`, but if the argument is *NULL*, do not output any value. - This format can only be used inside an object or an array. If used - inside an object, the corresponding key is additionally suppressed - when the value is omitted. See below for an example. - -`s#` (string) \[const char \*, int\] - -: Convert a UTF-8 buffer of a given length to a JSON string. - -`s%` (string) \[const char \*, size\_t\] - -: Like `s#` but the length argument is of type size\_t. - -`+` \[const char \*\] - -: Like `s`, but concatenate to the previous string. Only valid after - `s`, `s#`, `+` or `+#`. - -`+#` \[const char \*, int\] - -: Like `s#`, but concatenate to the previous string. Only valid after - `s`, `s#`, `+` or `+#`. - -`+%` (string) \[const char \*, size\_t\] - -: Like `+#` but the length argument is of type size\_t. - -`y` (byte array) \[const uint8_t \*, size\_t\] - -: Convert the byte array whose length is given to - its base64url string representation. - -`Y` (byte array) \[const uint8_t \*, size\_t\] - -: Like 'y' but output is base64. - -`y?`, `Y?` (byte array or null) \[const uint8_t \*, size\_t\] - -: Like 'y' or 'Y' but allows to output a JSON null value - either when the buffer is *NULL* or when the size is *0*. - -`y*`, `y*` (optional byte array) \[const uint8_t \*, size\_t\] - -: Like 'y' or 'Y' but do not put JSON value - either when the buffer is *NULL* or when the size is *0*. - This format can only be used inside an object or an array. If used - inside an object, the corresponding key is additionally suppressed - when the value is omitted. See below for an example. - -`n` (null) - -: Output a JSON null value. No argument is consumed. - -`b` (boolean) \[int\] - -: Convert a C int to JSON boolean value. Zero is converted to `false` - and non-zero to `true`. - -`i` (integer) \[int\] - -: Convert a C int to JSON integer. - -`I` (integer) \[json\_int\_t\] - -: Convert a C json\_int\_t to JSON integer. - -`f` (real) \[double\] - -: Convert a C double to JSON real. - -`o` (any value) \[json\_t \*\] - -: Output any given JSON value as-is. If the value is added to an array - or object, the reference to the value passed to `o` is stolen by the - container. - -`O` (any value) \[json\_t \*\] - -: Like `o`, but the argument's reference count is incremented. This is - useful if you pack into an array or object and want to keep the - reference for the JSON value consumed by `O` to yourself. - -`o?`, `O?` (any value) \[json\_t \*\] - -: Like `o` and `O`, respectively, but if the argument is *NULL*, - output a JSON null value. - -`o*`, `O*` (any value) \[json\_t \*\] - -: Like `o` and `O`, respectively, but if the argument is *NULL*, do - not output any value. This format can only be used inside an object - or an array. If used inside an object, the corresponding key is - additionally suppressed. See below for an example. - -`[fmt]` (array) - -: Build an array with contents from the inner format string. `fmt` may - contain objects and arrays, i.e. recursive value building is - supported. - -`{fmt}` (object) - -: Build an object with contents from the inner format string `fmt`. - The first, third, etc. format specifier represent a key, and must be - a string (see `s`, `s#`, `+` and `+#` above), as object keys are - always strings. The second, fourth, etc. format specifier represent - a value. Any value may be an object or array, i.e. recursive value - building is supported. - -Whitespace, `:` and `,` are ignored. - -More examples: - - /* Build an empty JSON object */ - wrap_json_pack(&result, "{}"); - - /* Build the JSON object {"foo": 42, "bar": 7} */ - wrap_json_pack(&result, "{sisi}", "foo", 42, "bar", 7); - - /* Like above, ':', ',' and whitespace are ignored */ - wrap_json_pack(&result, "{s:i, s:i}", "foo", 42, "bar", 7); - - /* Build the JSON array [[1, 2], {"cool": true}] */ - wrap_json_pack(&result, "[[i,i],{s:b}]", 1, 2, "cool", 1); - - /* Build a string from a non-null terminated buffer */ - char buffer[4] = {'t', 'e', 's', 't'}; - wrap_json_pack(&result, "s#", buffer, 4); - - /* Concatenate strings together to build the JSON string "foobarbaz" */ - wrap_json_pack(&result, "s++", "foo", "bar", "baz"); - - /* Create an empty object or array when optional members are missing */ - wrap_json_pack(&result, "{s:s*,s:o*,s:O*}", "foo", NULL, "bar", NULL, "baz", NULL); - wrap_json_pack(&result, "[s*,o*,O*]", NULL, NULL, NULL); - -Parsing and Validating Values ------------------------------ - -This section describes functions that help to validate complex values -and extract, or *unpack*, data from them. Like building values -<apiref-pack>, this is also based on format strings. - -While a JSON value is unpacked, the type specified in the format string -is checked to match that of the JSON value. This is the validation part -of the process. In addition to this, the unpacking functions can also -check that all items of arrays and objects are unpacked. This check be -enabled with the format specifier `!` or by using the flag -`JSON_STRICT`. See below for details. - -Here's the full list of format specifiers. The type in parentheses -denotes the JSON type, and the type in brackets (if any) denotes the C -type whose address should be passed. - -`s` (string) \[const char \*\] - -: Convert a JSON string to a pointer to a null terminated UTF-8 - string. The resulting string is extracted by using - json\_string\_value() internally, so it exists as long as there are - still references to the corresponding JSON string. - -`s%` (string) \[const char \*, size\_t \*\] - -: Convert a JSON string to a pointer to a null terminated UTF-8 string - and its length. - -`y` (byte array) \[uint8_t \*\*, size\_t \*\] - -: Convert an input string base64url encoded to its - byte array representation. The result and its length - are stored. The returned buffer must be freed by the caller. - -`Y` (byte array) \[uint8_t \*\*, size\_t \*\] - -: Like 'y' but input is base64. - -`n` (null) - -: Expect a JSON null value. Nothing is extracted. - -`b` (boolean) \[int\] - -: Convert a JSON boolean value to a C int, so that `true` is converted - to 1 and `false` to 0. - -`i` (integer) \[int\] - -: Convert a JSON integer to C int. - -`I` (integer) \[json\_int\_t\] - -: Convert a JSON integer to C json\_int\_t. - -`f` (real) \[double\] - -: Convert a JSON real to C double. - -`F` (integer or real) \[double\] - -: Convert a JSON number (integer or real) to C double. - -`o` (any value) \[json\_t \*\] - -: Store a JSON value with no conversion to a json\_t pointer. - -`O` (any value) \[json\_t \*\] - -: Like `O`, but the JSON value's reference count is incremented. - -`[fmt]` (array) - -: Convert each item in the JSON array according to the inner format - string. `fmt` may contain objects and arrays, i.e. recursive value - extraction is supported. - -`{fmt}` (object) - -: Convert each item in the JSON object according to the inner format - string `fmt`. The first, third, etc. format specifier represent a - key, and must be `s`. The corresponding argument to unpack functions - is read as the object key. The second fourth, etc. format specifier - represent a value and is written to the address given as the - corresponding argument. **Note** that every other argument is read - from and every other is written to. - - `fmt` may contain objects and arrays as values, i.e. recursive value - extraction is supported. - -`!` - -: This special format specifier is used to enable the check that all - object and array items are accessed, on a per-value basis. It must - appear inside an array or object as the last format specifier before - the closing bracket or brace. - -`*` - -: This special format specifier is the opposite of `!`. This is the default. - It must appear inside an array or object as the last format specifier - before the closing bracket or brace. - -Whitespace, `:` and `,` are ignored. - -Examples: - - /* root is the JSON integer 42 */ - int myint; - wrap_json_unpack(root, "i", &myint); - assert(myint == 42); - - /* root is the JSON object {"foo": "bar", "quux": true} */ - const char *str; - int boolean; - wrap_json_unpack(root, "{s:s, s:b}", "foo", &str, "quux", &boolean); - assert(strcmp(str, "bar") == 0 && boolean == 1); - - /* root is the JSON array [[1, 2], {"baz": null} */ - wrap_json_check(root, "[[i,i], {s:n}]", "baz"); - /* returns 0 for validation success, nothing is extracted */ - - /* root is the JSON array [1, 2, 3, 4, 5] */ - int myint1, myint2; - wrap_json_unpack(root, "[ii!]", &myint1, &myint2); - /* returns -1 for failed validation */ - - /* root is an empty JSON object */ - int myint = 0, myint2 = 0, myint3 = 0; - wrap_json_unpack(root, "{s?i, s?[ii]}", - "foo", &myint1, - "bar", &myint2, &myint3); - /* myint1, myint2 or myint3 is no touched as "foo" and "bar" don't exist */ - -Copyright ---------- - -Copyright (c) 2009-2016 Petri Lehtinen <petri@digip.org> - -Permission is hereby granted, free of charge, to any person obtaining a copy -of this software and associated documentation files (the "Software"), to deal -in the Software without restriction, including without limitation the rights -to use, copy, modify, merge, publish, distribute, sublicense, and/or sell -copies of the Software, and to permit persons to whom the Software is -furnished to do so, subject to the following conditions: - -The above copyright notice and this permission notice shall be included in -all copies or substantial portions of the Software. - -THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR -IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, -FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
