Additional Xcode Documentation Sets

Question

Xcode's help system includes documentation for all the Cocoa and Carbon APIs. However, it would be nice to also have documentation for the standard C and C++ libraries, POSIX APIs, BSD system calls, etc., integrated into the same system.

Are additional Xcode documentation sets available, or is there any way to integrate man pages or other documentation formats into the Xcode help system?

Answer 1

Doxygen knows how to integrate the documentation it generates to Xcode documentation, see Using Doxygen to Create Xcode Documentation Set. As far as I remember, it is an html set of files with a specific index.

At the end of that article, there is a reference to Documentation Set Guide.

Answer 2

Xcode can display man pages:

http://developer.apple.com/DOCUMENTATION/DeveloperTools/Conceptual/XcodeWorkspace/200-Documentation_Access/chapter_6_section_8.html

For this to work, the "Core Library" doc set or "All Doc Sets" must be selected.
