Markdown formats missing in doxygen outputs.

[Slyware]

Hi.

The ouputs files (html, rtf, ...) don't interpret ==highlight== and strikethrough format tags nor html tags as underline. I know that they may not be in the official Markdown standard but they are largely used by a many Markdown editors or viewers like Github does!.
Unlike bold or italic format tags, the above tags are displayed as raw source text in the outputs.
Is there a way to add these tags in the Doxygen parser or to customise the preprocessor?
Thanks.

Doxygen version: 1.8.14

In the current master version of doxygen some features should already be available. To see what you want can you please attach a, small, self contained example (source+config file in a tar or zip) that allows us to reproduce the problem?

Hi.
Here is an example of MD source edited in Typora (with option "Highlitghing" checked).
Ok, I saw that some of these formats are Markdown extensions but they are commonly used and so usefull.

Typora rendering is here:

Thanks a lot.

Regarding the support for strikethrough: I've just pushed a proposed patch, pull request #6535
Regarding the support for for underline has recently been added by means of #6384
Regarding the support for highlighted text (==), this is not available in the GitHub specifications.

Code has been integrated in master on github.
