Do not print a error message in loadYamlSettings

[felixsch]

While implementing the Data.Yaml.Config module I was stumbling over the this hardcoded putStrLn statement and I think it should be left to the user of the yaml library to decide how to handle exception and not print anything to stdout.

If I missed something and the putStrLn statement is worth keeping just ignore me and close the PR.

Thanks for you're awesome work!

Thanks for catching this, I definitely don't want a hard-coded putStrLn in here. However, this change will end up losing information on which file failed. Can I ask for a slightly different implementation: introduce a new exception type that includes both the FilePath in question and the underlying exception value and throws that instead of throwIO e. Basically, s/throwIO e/throwIO (LoadYamlSettingsException fp e). Does that make sense?

[felixsch]

Good idea, I added the LoadSettingsException exception.

Awesome, LGTM. One last request: can you add a minor version bump and a changelog entry?

[felixsch]

I added the changelog entry and bumped the version

Thanks! I made a slight tweak to make the version number 0.11.1.0 instead.
