"external" links broken?

[jacobwilliams]

I'm trying to understand how the "external" thing works (which I only just discovered!)

Running ford on the two projects in the external_project example, I don't get any errors, but the link for the remote objects are not clickable in the dependency diagram:

Should they be?

Yes they should. See for example the treelm docu, it has a node pointing to the aotus_module, which is external to that project. load_tem has a link to aot_get_val, which is external to the treelm project.

That documentation was generated with FORD in version 6.1.17.

• 6.1.17 works as intended
• 6.2.5 yields the broken links for me
• 6.2.0 results in the following error:

Traceback (most recent call last):

    raise BadType(
ford.graphs.BadType: "Unrecognised object type 'str' when constructing graphs"

I think that error was fixed in #488 + #494, though somehow it replaces the urls now and instead assumes the links to be internal. The treelm project is affected by #501, so FORD 6.2.1-6.2.3 run into the reported KeyError. In version 6.2.4 the URL linking to the external project documentation is gone.

Oh yes, this should definitely work! I'm afraid it will be a week or two before I can look at this, but it's on my radar
