Re: Disable messages with GHC API

Adding `handleSourceError` around it makes no difference. Which makes sense, as I don't think warnings count as exceptions, otherwise my code would never have completed in the first place. On 3 February 2017 at 12:50, Matthew Pickering wrote:

The errors are eventually caught and printed by "handleSourceError" which is used a few times in your code. You could either modify one of these to not print out any errors or try something more intelligent like is in `parUpsweep_one` which does use the `log_action` in order to print the errors out.

In Intero, after loading modules, for each one I run the following function: https://github.com/commercialhaskell/intero/blob/300ac5a/src/GhciInfo.hs#L75...

If there are warnings or any output, they get outputted. As they are already outputted by regular :load, I don’t need the same output twice.

How do I disable non-severe output for any GhcMonad m => m a? I’m using GHC 8.0.1 presently.

I tried the following before calling getModInfo, expecting there to be no output anymore:

+ GHC.setSessionDynFlags + df {log_action = \ref dflags severity srcSpan style msg -> return ()}

And this had no effect. I tried some other things but ran out of patience to keep a record of them all.
