KPF(Kylin Plugin Framework) is a light weight plugin framework for Qt, free to cooperate with 3rd-party library without any code injection.

• Light weight: Only a single dll file.
• Dynamic load: Load any QObject class to build your program architecture by configuration file, just like building LEGO!
• No injection: Any QObject classes could be supported with a single line of declaration like Q_DECL_METATYPE, you can write it anywhere before loading the object. So you could configure any QObject classes from 3-rd party library without any code injection.
• EventBus: Publish/Subscribe mechanism supported to decouple sender and receiver:
  • Better performance than signals&slots.
  • Easier to write than signals&slots.
  • Both synchronized and asynchronized events are supported, just like Qt::DirectConnection and Qt::QueuedConnection.
• Better signal&slots:
  • Connect signals and slots by configuration file is also supported, just like eventbus.
  • Published event could connect to signals/slots, signals could connect to subscribed event too.
• Configure everything:
  • QObject's every property could be configured
  • QObject's object-tree-hierarchy is also supported.
  • Object can be initialized in sub-thread by configuration, you needn't write any code about it.
• Component: Separated configuration files are supported -- a component file is used to describe a subset of the configuration, and it behaves like a single concrete object, to be configured in other components or main configuration file.
• Powerful log system: KPF use log4qt(Not which one migrated from log4j) to record logs.
• Plentiful APIs: Advanced user can control every behaviors described above.

Only coments at present, sorry for this.

There's a simply example in test folder, which shows the features with configuration file and several classes.

1. Submit code before 2019.7.7
2. Finish documentation with Doxygen(See Another repository for example).
3. Migrate configuration file format from json to xml.
4. Migrate log system to log4qt(The existing logging system in KPF is prototype of my log4qt repo).
5. Unit tests and CI support for travis, appveyor and coveralls.
6. Other further maintenance:
   1. Operational monitoring;
   2. Hotswap support.
   3. ...
