Hello Matthew,

During the time I have already figured the problem out. My original thought is to log the errors from code to some file. Later I did find a function being able to collect the diagnostics.

On the other hand, I'm new to the mailing list, and after I asked the question I have further understood what the list is for. I think that my question should be not suitable for the list, and sorry for that.

Hi Gunda,

Could you be a bit more precise about what you want to achieve? HLS
already displays type errors in your program, perhaps it would be
better to ask someone on the HLS issue tracker how to use their API to
do what you want.

My current thought is, I can collect diagnostics or the error messages and extract the type error infos. I have tried to referred to the Haddock documentation for GHC API, but I'm still not sure which function should I use.
