Thanks.

You assume wrong. Eglot supports hundreds of servers. I only have the
servers I work or worked with in the past. "Supports foo server " means
solely that someone knowledgeable with foo tried it and reported good
results at some point, so they requested to add a server invocation to
eglot-server-programs.
Anyway, I couldn't reproduce your problem simply because the Main.hs
program you provided does not seem to produce any diagnostics, according
the haskell-language-server I installed in my system, which identifies
itself as
haskell-language-server version: 1.9.1.0 (GHC: 9.2.8) (PATH: /usr/bin/haskell-language-server)
I'm not a Haskell programmer, so I don't know if this makes sense to
you.
In the events log, the publishDiagonstics message is the following:
[jsonrpc] e[22:01:33.466] <-- textDocument/publishDiagnostics {
"jsonrpc": "2.0",
"method": "textDocument/publishDiagnostics",
"params": {
"diagnostics": [],
"uri": "file:///home/capitaomorte/Downloads/bug73500/src/Main.hs",
"version": 2
}
}
Notice the empty JSON array. However, when I change your Main.hs to
what is likely a nonsensical Haskell program:
module Main where
isAscending :: [Int] -> Bool
isAscending [] = True
isAscending [x] = x
-- ^ this second 'x' _is_ underlined
isAscending (x : y : ys) = x < y && isAscending (y : ys)
main :: IO ()
main = putStrLn "Hello, bug 73500!"
Then I see the second x being underlined with a 1-char-long diagnostic,
the corresponding LSP event being:
[jsonrpc] e[22:05:21.403] <-- textDocument/publishDiagnostics {
"jsonrpc": "2.0",
"method": "textDocument/publishDiagnostics",
"params": {
"diagnostics": [
{
"code": "-Wdeferred-type-errors",
"message": "• Couldn't match expected type ‘Bool’ with actual type ‘Int’\n• In the expression: x\n In an equation for ‘isAscending’: isAscending [x] = x",
"range": {
"end": {
"character": 19,
"line": 4
},
"start": {
"character": 18,
"line": 4
}
},
"severity": 1,
"source": "typecheck"
}
],
"uri": "file:///home/capitaomorte/Downloads/bug73500/src/Main.hs",
"version": 25
}
}
I have now removed haskell-language-server from my machine.
