Cannot render html when using a local language via #lang reader.

[LeifAndersen]

Namely, I run:

raco cover

The coverage runs fine. However, when cover goes to generate the html, I get the error:

dumping coverage info into "coverage"

Because this is only a problem with html generation and not coverage itself, the error does not happen when using the coveralls or codecov extensions. I should point out that this is one of the commit that is giving raco cover problems. And the file that is giving it problems (video.scrbl), starts out with:

#lang reader "viddoclang.rkt"

(where viddoclang.rkt is in the same directory as vidlang.)

Strange. While trying to make a test case for this I get the same error but from a much earlier point (during module instrumentation).

As a work around for now, does this go away if you use the collection path instead of a relative path?

[LeifAndersen]

As in move the file to lang/reader.rkt? If so, ya, that does make the problem go away. Although I would much rather be able to use a relative path if possible. :)

Can't you do #lang reader video/test/videolang instead of #lang reader "videolang.rkt"?

[LeifAndersen]

Ah, okay, that's what you meant. Yes, that does seem to work.
