Autocomplete showing methodinformation

Hello everyone

I have a general question concerning autocomplete. I am using Atom with PlatformIo and enjoying the overall functionality programming on microcontroller.
I am generally using Netbeans and now I used to the autocomplete function, which also shows basic information about the variables and functions.

method_ex

Autocomplete is working fine in Atom (PIO) but only shows the available functions and return types.

Is there a package which can include metainformation from the documentation (like javadoc)?

Thanks
