Getting Xcode to recognise C++ header files without the '.h' extension (OpenSceneGraph)

Question

OpenSceneGraph uses header files without the '.h' extension. Is there a way of getting Xcode to recognise the syntax as C++ and therefore allow me to have highlighting and jumping to definitions etc?

Eg: No highlighting:

Yes. Toggle the right panel (the rightmost icon of the "View" section of the toolbar, arrow 1 in the screenshot) with your file selected. Select the document tab in the panel (arrow 2), then find "File Type" under "Identity and Type" (arrow 3). Choose "C++ header" in the dropdown list.

You will need to reopen the file for the syntax coloring to kick in.

Is there a way to make Xcode do this automatically for certain extension so that it doesn't have to be repeated manually for each such file? – Bladderwort

I'm on a Windows machine right now so I can't check, but while I know for sure you can't do that for files without extensions, I'm pretty sure you can do that for specific extensions from one of the tabs in the project settings. Click your project in the file explorer and check the build rules. – Vikki

What about for files in library/system headers that are not part of any project? – Valvular

@OrangeDog, can't help you with that one. – Vikki
