Steps to reproduce

Create a blank file then type code.

Expected behaviour

Completion shows up while typing

Actual behaviour

Completion stop showing up after typing a few lines. But coc with hls 0.9.0 or vscode with hls 1.3.0 don’t have that problem.

Hi, thanks for the bug report, i dont see any error in the output log but i am not sure if it is set to trace level. Could you execute the server with -d? otoh, it is reproduced with another editor?

aplqo · 2021-09-01T15:25:13Z

I run server with -d flag.I think HLS 1.0.0(which has the problem) reported a error:

I tried some editors. Here are results:

vim with HLS 0.9.0: Not encounter problem
vim with HLS 1.0.0 or 1.2.0 or 1.3.0: Has problem
vscode with HLS 1.3.0: Not encounter problem.

I don't know if hls has problem or coc.nvim has problem ,but I tried vim inside a container with newly installed vim and coc, so I think the problem isn't caused by other vim extension.

aplqo · 2021-09-07T04:51:57Z

It seems that HLS stops responding after typing some text. And when completion stops, HLS often reports a parse error on the beginning of the line.I think the parse error is caused by partial input.

aplqo · 2021-09-12T12:56:52Z

Git bisect shows that 9c40dcf is the first commit to have this issue.

aplqo · 2021-09-16T16:18:05Z

I found that almost every time HLS stops working, it reports a error haskell-language-server: Data.Text.Internal.Fusion.Common.index: Index too large .

input file:

module DataAbstract.Set.UnordListDuplicate where

import DataAbstract.Set.UnorderedList (elementOfSet, intersection, mkSet)
newtype Name x = Name x der
adjoin :: (Eq a) => a -> [a] -> [a]
adjoin x s = x : s

union :: (Eq a) => [a] -> [a] -> [a]
union = (++)

{-
   1. adjoin and union become more effiecient, but elementOfSet become slower
   2. When there many adjoins and unions
   -}

lsp logs before error:
