-### Application Framework Binder
-This is an undergoing work, publication is only intended for developers to review and provide feedback.
+# AGL Framework Binder
-### Licence
-As today the code is under GLPV3, while no decision as been taken yet, it will certainly move under a different licence like GPV2, Apache or MIT.
+This project provides the binder component of the the microservice architecture
+of Automotive Grade Linux (AGL).
-Final goal is keep the engine public while allowing people to load non open-source plugins. The code already leverage other opensource
-libraries especially libmicrohttpd & libjson. Finally what ever Licence is chosen it should be compatible with dependencies and automotive
-industry requirementsas the primary target for this code is AGL.
+This project is available there https://git.automotivelinux.org/src/app-framework-binder/
-### Building
- Building Application Framework Binder requires the following libraries:
+It can be cloned with **git clone https://git.automotivelinux.org/src/app-framework-binder**.
- * libmagic ("libmagic-dev" under Debian/Ubuntu, "file-devel" under OpenSUSE);
- * libmicrohttpd ("libmicrohttpd-dev/devel");

+## Building
+
+### Requirements
+
+Building the AGL framework binder has been tested under
+ **Ubuntu**, **Debian** and **Fedora 26** with gcc 6 and 7.
+
+It requires the following libraries:
+
+ * libmagic ("libmagic-dev" under Ubuntu, "file-devel" under Fedora);
+ * libmicrohttpd >= 0.9.55 (fetch and build from "http://ftp.gnu.org/gnu/libmicrohttpd");
* json-c ("libjson-c-dev/devel");
* uuid ("uuid-dev/libuuid-devel");
+ * openssl ("libssl-dev/openssl-devel");
+ * systemd >= 222 ("libsystemd-dev/systemd-devel");
- optionally, for plugins :
+The following library can be used for checking permissions:
- * rtl-sdr >= 0.5.0 (fetch and build from "git://git.osmocom.org/rtl-sdr");
+ * cynara (https://github.com/Samsung/cynara)
- and the following tools:
+and the following tools:
+ * gcc;
* pkg-config;
- * cmake >= 2.8.8.
+ * cmake >= 3.0
+
+To install all dependencies under Ubuntu (excepting libmicrohttpd), please type:
+
+ $ apt-get install libmagic-dev libjson-c-dev uuid-dev libsystemd-dev libssl-dev gcc make pkg-config cmake
+
+or under Fedora (excepting libmicrohttpd and rtl-sdr):
+
+ $ dnf install git passwd iproute openssh-server openssh-client
+ $ dnf install file-devel gcc gdb make pkgconfig cmake
+ $ dnf install json-c-devel libuuid-devel systemd-devel openssl-devel
+
+### Simple compilation
+
+The following commands will install the binder in your subdirectory
+**$HOME/local** (instead of **/usr/local** the default when
+*CMAKE_INSTALL_PREFIX* isn't set).
+
+ $ git clone https://git.automotivelinux.org/src/app-framework-binder
+ $ cd app-framework-binder
+ $ mkdir build
+ $ cd build
+ $ cmake -DCMAKE_INSTALL_PREFIX=$HOME/local ..
+ $ make install
+
+### Advanced compilation
+
+You can tune options when calling cmake. Here are the known options with
+their default values.
+
+ $ git clone https://git.automotivelinux.org/src/app-framework-binder
+ $ cd app-framework-binder
+ $ mkdir build
+ $ cd build
+ $ cmake \
+ -DCMAKE_INSTALL_PREFIX=/usr/local \

+## Simple demo

+### Testing/Debug
+
+```
+$ ${AFB_DAEMON_DIR}/build/src/afb-daemon --help
+$ ${AFB_DAEMON_DIR}/build/src/afb-daemon --port=1234 --token='' --ldpaths=${AFB_DAEMON_DIR}/build --sessiondir=/tmp --rootdir=${AFB_DAEMON_DIR}/test

+
+### Starting
+
+```
+$ afb-daemon --help
+$ afb-daemon --verbose --port=<port> --token='' --sessiondir=<working directory> --rootdir=<web directory (index.html)>
+```
### Example
-$ afb-daemon --verbose --rootdir=/home/fulup/.AFB --alias=icons:/usr/share/icons
-### Directory & Path
+```
+$ afb-daemon --verbose --port=1234 --token='' --sessiondir=/tmp --rootdir=/srv/www/htdocs --alias=icons:/usr/share/icons

+
+### Directories & Paths
+
Default behaviour is to locate ROOTDIR in $HOME/.AFB
### REST API
-Developer should mainly provides a structure with APIs name, corresponding methods and optionally some context and a handle.
-A handle is a void* structure that it is passed to the api callback. The API receive the query and well as post data, incase
-a post method was used. Every method should return a JSON object or NULL in case of error.
-
-API plugin can be protected from timeout and other errors. By default this behaviour is deactivated, use --apitimeout to activate it.
-
- STATIC AFB_restapi myApis[]= {
- {"ping" , (AFB_apiCB)ping , "Ping Function", NULL},
- {"action1" , (AFB_apiCB)action1 , "Action-1", OptionalHandle},
- {"action2" , (AFB_apiCB)action2 , "Action-2", OptionalHandle},
- {0,0,0}

-### HTML5 and Angular Redirect
+### HTML5 and AngularJS Redirects
-Binder support HTML5 redirect mode even with an application baseurl. Default value for application base URL is /opa
+Binder supports HTML5 redirect mode even with an application baseurl.
+Default value for application base URL is /opa.
See Application Framework HTML5 Client template at https://github.com/iotbzh/afb-client-sample
-If the Binder receive something like http://myopa/sample when sample is not the homepage of the Angular OPA. The the serveur
-will redirect to http://myopa/#!sample this redirect will return the Index.html OPA file and will notify angular not to display
-the homepage by to goto samplepage.
+If the Binder receives something like _http://myopa/sample_ when sample is not the homepage of the AngularJS OPA,
+it will redirect to _http://myopa/#!sample_.
+This redirect will return the _index.html_ OPA file and will notify AngularJS not to display the homepage, but the sample page.
-Warning: in order Angular application to work both with a BASEURL="/" and BASEURL="/MyApp/" every page references have to be relative.
-Recommended model is to develop with a BASEURL="/opa" as any application working with a BASEURL will work without, when the opposite it not true.
+Warning: in order for AngularJS applications to be able to work with both BASEURL="/" and BASEURL="/MyApp/", all page references have to be relative.
-Note: If a resource is not accessible from ROOTDIR then --alias should be use ex: --alias=/icons:/usr/share/icons. Only alias designed to access
-external support static files. They should not be used for API and OPA.

+Note: If a resource is not accessible from ROOTDIR then the "--alias" switch should be used, as in: --alias=/icons:/usr/share/icons.
+Only use alias for external support static files. This should not be used for API and OPA.
-### On going work
- -- Dynamic load of plugins. While everything is designed to support dynamically loadable plugins, this part is not done yet.
- -- Javascript plugins. As today only C plugins are supported, but JS plugins are on the ToDo list.
+### Ongoing work
+Javascript plugins. As of today, only C plugins are supported, but JS plugins are on the TODO list.
