Above was with Version 0.1.0.0, Git revision 19d5494f519934c0208d6816fcee7545e6aef443 (1092 commits) x86_64 from alanz@19d5494

Using current master has the same result.

@unode The languageClient.log messages are all harmless:

• The first two indicate that hie sends non-standard keys in json data (it does so because vscode does)
• The last one just indicates that vim completion manager (which is optional) is not installed. The check is done in LanguageServer by catching an exception, so the message is ugly.

The hlint message in LanguageServer.log is a duplicate of #400 . As a temporary workaround don't delete hie's .stack-work dir once it is built (or delete all but the 2 files mentioned in the linked issue)

Please check that the latest hie works with this workaround applied. Note that you need a --stack-yaml option for ghc-8.0.2 now as the default is for 8.2.2. If hie works we'll close this issue as a duplicate.

[unode]

I can't reproduce this anymore with the instructions provided. But I'm having other issues.

Since both haskell-ide-engine and LanguageClient.neovim are moving quite fast these days, I'll wait for an official release for further tests.

Thanks for the support!

I have just encountered a similar problem:

HIE worked today in the morning. Arch Linux, ghc 8.2.2

[nponeccop]

@marmistrz This is actually #400. Basically, don't delete hlint.yaml from the HIE build dir

[marmistrz]

I've just deleted ~/.stack and HIE got broken. So it's not only the thing of not deleting the build root.

[alanz]

Is this still a problem?

[unode]

I haven't used nvim with hie in a while. Feel free to close.
