[Doxygen-develop] Adding canonical links to HTML documentation

[Philipp M. <phi...@ge...>]

Hi, 

I'm looking for a way to inject <link rel="canonical" href=""/> tags
into doxygen HTML output.

The obvious way is to do it in a post-processing, but having the ability
to access the filename of the currently generated file (incl. it's path
when CREATE_SUBDIRS is enabled) inside the HTML_HEADER seems like a
better solution.

It seems to be straight-forward to implement by adding another
substitution to substituteHtmlKeywords in htmlgen.cpp

Would it be possible to add something like that? I could provide a patch
if wanted.

Cheers,
Philipp
