Add maindir nimdoc configuration item that points to the directory of theindex.html

[theamarin]

This is done to support global links in the documentation's menu in the nimdoc.cfg as follows:

<ul class="simple-boot">
  <li><a href="$maindir/index.html">Index</a></li>
  <li><a href="$maindir/mydoc.html">My documentation</a></li>
  <li><a href="$theindexhref">Generated index</a></li>
</ul>

Using this $maindir configuration item, one might even get rid of the $theindexhref and use $maindir/theindex.html instead.

Nice but please add a test case for this or patch an existing one.

Hi @Araq, thank you very much for your quick response! Please note I am still quite new to Nim so I would be happy to get some pointers here.

I would be happy to add a corresponding test, but could not find a valuable examples on how to craft it.
Could you please give me a hint how to test this specific feature?
The existing tests in tests/nimdoc/* appear to merely check language features but do not give me a clue on how to check on resulting nimdoc configuration.
Maybe it is worth to move the code to derive maindir into a separate function that can be tested separately?
Does it need to be public (*) so I can call it from a test?
Thank you!

Look at nimdoc/testproject/expected for example. nimdoc/tester.nim is a special test program, not based on testament that can be tweaked further.

I now use the following entry in nimdoc.cfg to point to "my module", which also works with nested projects, i.e., from other modules within subdirectories:
<li><a href="$theindexhref/../mymodule.html">My Module</a></li>
This is maybe a bit hacky but avoids the proposed patch.
