Ticket #207 (new defect)
haddock: internal error: spliceURL UnhelpfulSpan
|Reported by:||selinger||Owned by:|
With Haddock 2.8, I got this error message occasionally; with Haddock 2.9.4, I get it *all the time*. Minimal example attached.
The problem seems to arise when one has some function without a type signature, and the --source-entity option is used. The old behavior (2.8) was to ignore such a function. The new behavior is to generate the type signature, but then fail with the above error message.
Obviously, the above error message was not intended for end users; "Missing type signature" or "Can't find this line in your file" would be a better error message. Still better would be not to produce an error at all.
