The first part, where all the headers line are there, works great, but
the second source block for a newly defined language tikz (an alias to
latex with some default headers) does not work unfortunately. In the
exported version, I get a minted source block and not a link.

Am I doing something wrong? Is it possible to have a shorter syntax for
these blocks, or do I have to put all the header lines all the time?

Thanks,

Alan
