### Application Framework Binder
This is an undergoing work, publication is only intended for developers to review and provide feedback.
-### 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.
+### License
+As of today, the code is licensed under GLPv3. While no decision as been taken yet, it will certainly switch to a different licence: GPLv2, Apache or MIT e.g..
-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.

* libmicrohttpd ("libmicrohttpd-dev/devel");
* json-c ("libjson-c-dev/devel");
* uuid ("uuid-dev/libuuid-devel");
* dbus ("libdbus-1-dev/dbus-1-devel");
- optionally, for plugins :

+optionally, for plugins :
* alsa ("libasound2-dev/alsa-devel");
* rtl-sdr >= 0.5.0 (fetch and build from "git://git.osmocom.org/rtl-sdr");

### Example
-$ afb-daemon --verbose --rootdir=/home/fulup/.AFB --alias=icons:/usr/share/icons

-### Directory & Path
+### 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.

+A handle is a void* structure automatically passed to API callbacks. Callbacks also receive HTTP GET data as well as HTTP POST data, in case 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.

See Application Framework HTML5 Client template at https://github.com/iotbzh/afb-client-sample

-the homepage by to goto samplepage.

-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.

-### On going work
+### Ongoing 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.
