Reference Provider not working

[andys8]

With purescript-language-server and Vim/CoC "Find references/usages" is not working in most cases.

Example

https://github.com/jonasbuntinx/purescript-react-realworld/blob/d59eaf5c3431ea465db792f291eede42dc6190c7/src/Conduit/Page/Article.purs#L52

Vscode

Vscode is working

Vim

Vim is not working

Comparison with purs ide

I tried if I could use purs ide client to show references or not.

With load and usages, the result is empty.

{ "command": "load" }

{ "command": "usages", "params": { "module": "Conduit.Page.Article", "namespace": "value", "identifier": "mkArticlePage" } }
{"result":[],"resultType":"success"}

But when building a file that's using it, before it'll work:

{ "command": "rebuild", "params": { "file": "src/Conduit/Root.purs", "actualFile": "src/Conduit/Root.purs" } }
{"result":[],"resultType":"success"}

{ "command": "usages", "params": { "module": "Conduit.Page.Article", "namespace": "value", "identifier": "mkArticlePage" } }
{"result":[{"start":[30,18],"name":"src/Conduit/Root.purs","end":[30,31]}],"resultType":"success"}

Debugging

I haven't looked into the code.

I found a way to reliably get usages to work in a specific case. Hopefully that will help with debugging the actual cause.

1. Open module Conduit.Root (using module)
2. Jump to defintion on mkArticlePage
3. It'll fail

[Trace - 10:34:53 PM] Sending request 'textDocument/definition - (1)'.
Params: {
    "textDocument": {
        "uri": "file:///home/andreas/dev/repository/purescript-react-realworld/src/Conduit/Root.purs"
    },
    "position": {
        "line": 29,
        "character": 20
    }
}

[Trace - 10:34:53 PM] Received response 'textDocument/definition - (1)' in 29ms.
No result returned.

4. Click again "Jump to defintion"
5. This time it'll work and open Conduit.Page.Article

Params: {
    "textDocument": {
        "uri": "file:///home/andreas/dev/repository/purescript-react-realworld/src/Conduit/Root.purs"

    "position": {
        "line": 29,
        "character": 17
    }
}

            "line": 51,
            "character": 0
        },
        "end": {
            "line": 51,
            "character": 0
        }
    }
}

6. Now "Jump to / show usage" on the definition of mkArticlePage
7. It'll jump back to where it's used

        "character": 0
    },
    "context": {
        "includeDeclaration": false
    }

            }
        }
    }
]

Can you confirm the purs ide server globs are the same in both cases, if that isn't so then there's not much hope
