Development of Plugins
Information about writing a plugin and getting it included in SmartHomeNG can be found here:
More info upon the functions and their parameters can be found here. The core which resides in bin/smarthome.py is the heart of the system.
It is accessible via
sh-Object. The libraries provide extra functionality like scheduling, database access, connections etc.
A plugin consists of a minimum of three files (without user- and developer documentation):
|__init__.py||The file containing the Python source code|
|plugin.yaml||The file containing the metadata of the plugin|
|locale.yaml||Optional, containing translation strings for the multi-language implementation of a web interface|
|README.md or README.rst||A basic documentation file (in English language) - The documentation can be written in markdown or restructured text format|
|user_doc.rst||Optional, a user documentation file (in German language). It will be included in the navigation of the user documentation.|
|developer_doc.rst||Optional, a developer documentation file (in English language). It will be included in the navigation of the developer documentation|
If one of the documentation files (user_doc.* or developer_doc.*) should include images or other assets, create a directory named assets in the plugin directory and put the files in that directory ../<plugin>/assets. The documentation files (user_doc.* or developer_doc.*) need not to be referenced in the metadata file plugin.yaml
The first Heading of the user_doc.rst / user_doc.md or developer_doc.rst / developer_doc.md MUST be the short-name of the plugin in lower case.
It is used as the entry in the navigation bar of the documentation. Choosing an other top level header for these files would make the documentations navigation inconsistent.
The plugin may have the following subdirectories:
|_pv_<version>||A directory containing a former version of the plugin (the dots of the version number are replaced by underline. eg: 1.3.5 -> 1_3_5)|
|assets||Containing files user by the user_doc or developer_doc files|
|webif||Containing the files of a webinterface, if the plugin implements one. This directory should contain two sub directories (static and templates).|
|webif/static||Containing the files of a webinterface, if the plugin implements|
|webif/static/css||Optional, if cascading style sheets are needed by the web interface, they go here.|
|webif/static/img||Optional, if images are needed by the web interface, they go here.|
|webif/templates||The templates directory should contain the html tempate(s), at least index.html.|
The plugin code is a class based on the class SmartPlugin. The methods of SmartPlugin are documented here.
