Describe the issue / bug.

I added these configs in launch.js,

After F5 debug, already vscode debugging child processes.

but, breakpoint in main process used in folder

While generating docs for the v5.2, I noticed our doc coverage dropped to 99% due to a forgotten doc here. and was wondering if it is a good idea to add a CI step to make sure any newly introduced code is properly documented

Solutions

1. Convert INO files to CPP

2. Manual prototype declaration

#ifdef DO_NOT_USE
typedef int32_t delaytype;
void thisShouldNotAppearInTheBinary(delaytype timer); // aded manually
void thisShouldNotAppearInTheBinary(delaytype timer) {
  delay(timer);
}
#endif
