I am writing a new project wizard to create a C++ project for the Sming (ESP8266) framework. I would like to add search paths to the project properties C/C++ parser options so that auto complete works for the Sming library functions. I see that this is stored in the <Project><Extensions><code_completion> section of the project file but I cannot figure out how to add paths using wizard scripting.
I have this working using the simple template method but that is not as user friendly, hence my desire to use a wizard.
