Autocomplete does not work for all R files

[Yousuf28]

on my windows laptop I use gvim 9.0. I set up coc-r-lsp with languageserver. The autocomplete works on some R file, but not work on all R files. On thing I noticed that, if R file in git repository, autocomplete does not works.

When R file in other directory, it works

when R file in git repo, it does not work

• here is my _vimrc for gvim

have you setup the root directory in coc-settings.json correctly? It should be either the home directory or the root of the git repo.

here is the coc-settings.json file content of my windows which is not working correctly.

"languageserver": {
    "R": {
        "enable": true,
        "command": "C:\\Program Files\\R\\R-4.1.2\\bin\\x64\\R.exe",
        "r.lsp.path": "C:\\Program Files\\R\\R-4.1.2\\bin\\x64\\R.exe",
        "r.lsp.debug": true,
        "args": [
            "--slave",
            "-e",
            "languageserver::run()"
        ],
        "filetypes": [
            "r"
        ]
    }
}

not sure how to setup correctly.

but on my mac, this is the coc-settings.json file. and autocomplete working fine in any R file whether it is home directory or in a git directory.

"languageserver": {
    "R": {
	"enable": true,
        "command": "/usr/local/bin/R",
        "args" : [ "--slave", "-e", "languageserver::run()"],
        "filetypes" : ["r"]
    }
}

I don't use windows, so I have no idea what is happening. Neovim builtin lsp works fine though. This is the default configuration of the R lsp in neovim:

https://github.com/neovim/nvim-lspconfig/blob/1028360e0f2f724d93e876df3d22f63c1acd6ff9/lua/lspconfig/server_configurations/r_language_server.lua#L8

You can see that the root directory is either home directory or git root.

However I do have some impression that I once tried to modify the root directory specs and the completion does not work. So I just used the default way of nvim-lspconfig which handles root directory works just fine.

@milanglacier Thank you so much for directing me to nvim lspconfig. It was quite easy to set up for R and python. I spent quite bit of time on nvim-R and coc-vim but could not figure out how to set up properly for windows which is my working laptop. I was using vim, now I am using neovim. The telescope plugin really cool. Thanks
