6 years ago Hmm, honestly no idea on atm how to solve this.
I can get the following output from HIE --debug,

Why not:
module Main (module Main) where
Note: an explicit list is usually better

6 years ago @Tehnix Doesn't this work for you:
test :: [Char] -> [Char]
test = reverseApply hint: Use String works fine in this case.
It works on my machine with both VSCode and Atom. HIE Version 0.1.0.0 x86_64 ghc-8.2.2

6 years ago It seems it's working again, at least in VSCode.
Btw, if you would like more debug information, you can set a custom executable for HIE in ide-haskell-hie's settings.
One I usually use for debuggin, is,
#!/usr/bin/env bash
DEBUG=1
indent=""
function debug {
if [[ $DEBUG == 1 ]]; then
echo "$indent$@" >> /tmp/hie-custom-wrapper.log
fi
}
curDir=`pwd`
debug "Launching HIE for project located at $curDir"
indent=" "
# Launch the hie for the LTS compiler (assuming built with --copy-compiler-tools).
debug `stack exec -- which hie`
stack exec -- hie --lsp --vomit --debug -l /tmp/hie.logwhich enables --vomit on ghc-mod, and logs to /tmp/hie.log, with the debug statements going to /tmp/hie-custom-wrapper.log.
As for what's causing it, I'm still not really sure.
Having following code:
The following messages are printed from LSP debug:
