Rib hangs when building site that imports additional modules about rib

[srid]

Have you tried updating rib to latest revision?

[JonathanReeve]

Just tried that now. Once I got filepaths and everything working again for the new version, though, I find that I'm still running into the same problem. Rib just seems to hang after compiling everything. Here's the full error message:

@JonathanReeve I tried to reproduce this in https://github.com/JonathanReeve/jonreeve.com/tree/rib

It is not that "rib hangs" - rather that ghcid is spitting out warnings in your code. If there are any warnings it does not run the main entry point (which gave you the impression of it hanging). You can either fix those warnings, or pass --warnings to ghcid to make it ignore it (I'd generally recommend fixing the warnings).

For the later approach, which also quickly fixes things for you, try:

nix-shell --run 'ghcid --warnings  -T ":main -wS"'

(Note that with new rib you need -wS argument, instead of serve)

[JonathanReeve]

Great! That did the trick. I guess I'd thought warnings wouldn't block ghcid, but now I see that they do. Thanks! I'll close this.
