blink completion

[mohelm]

Hey - many thanks for this plugin.

Does it work with blink.cmp? How would one use this cmp.r package in this case? Many thanks.

[samtrek]

you can use blink compact as their is no official blink plugin for r completion for now, you can use this as the basis for starting your own
{ "saghen/blink.cmp", dependencies = { "R-nvim/cmp-r", "saghen/blink.compat" }, opts = { sources = { compat = { "cmp_r"}, }, }, }

[mohelm]

many thanks. the keymaps are not required, right?

[samtrek]

no I have updated it to what a generic install should look like

I have things configured pretty much out of the box, with some tweaks added over time. I'm not using blink.compat, but maybe should be ...

Anyway, my lua is here:

return {
    "saghen/blink.cmp",
    opts = {
        snippets = {
            expand = function(snippet, _)
                return LazyVim.cmp.expand(snippet)
            end,
        },
        appearance = {
            -- sets the fallback highlight groups to nvim-cmp's highlight groups
            -- useful for when your theme doesn't support blink.cmp
            -- will be removed in a future release, assuming themes add support
            use_nvim_cmp_as_default = false,
            -- set to 'mono' for 'Nerd Font Mono' or 'normal' for 'Nerd Font'
            -- adjusts spacing to ensure icons are aligned
            nerd_font_variant = "mono",
        },
        completion = {
            accept = {
                -- experimental auto-brackets support
                auto_brackets = {
                    enabled = true,
                },
            },
            menu = {
                draw = {

                },
            },
            documentation = {

            },
            ghost_text = {
                enabled = vim.g.ai_cmp,
            },
        },

            -- with blink.compat

hey - has this changed now with the new lsp? i noticed that my completion does not work that well anymore...it is qutie sluggish and i feel also incomplete?

[PMassicotte]

What is your setup?

[mohelm]

this one:

blink.setup {

  appearance = { use_nvim_cmp_as_default = false, nerd_font_variant = "mono" },
  fuzzy = { implementation = "prefer_rust_with_warning" },
  snippets = { preset = "luasnip" },
  completion = { menu = { border = nil, scrollbar = false, draw = { columns = columns } } },
  sources = {
    compat = { "cmp_r" },
    default = { "snippets", "lazydev", "cmp_r", "lsp", "path", "buffer" },
    providers = {
      lazydev = {
        name = "LazyDev",
        module = "lazydev.integrations.blink",
        score_offset = 100, -- show at a higher priority than lsp
      },
      cmp_r = {
        name = "cmp_r",
        module = "blink.compat.source",
        score_offset = 3,
        opts = { doc_width = 150 },
      },
      snippets = {
        module = "blink.cmp.sources.snippets",
        score_offset = 6,
      },
    },
  },
}

[PMassicotte]

If you are using the latest version of R.nvim, you do not need the compat layer anymore.

[jalvesaq]

I added a warning that it's deprecated and disabled it when the module "r.lsp" exists. Can you update cmp-r and try again, please?

[mohelm]

hey thanks - i saw your commit when updating, but did not see the warning.
i will check later when i have more time and also update the config probably.

[mohelm]

hey i removed cmp-r and everything seems to work quite well. thanks a lot!!

[jalvesaq]

hey i removed cmp-r and everything seems to work quite well. thanks a lot!!

Thanks for the feedback! The purpose of the warning is to let people know that cmp-r must be uninstalled. But warnings are not always visible during completion.

[jalvesaq]

@PMassicotte, I think it's time to archive the cmp-r repository...

[PMassicotte]

Yes, good idea. Not used anymore!

[jasonpott]

Just a heads up that the Lazyvim R language bundle included in Lazyvim Extras installs cmp-r by default.

I had CMP-R included manually in my config and struggled to figure out why it remained installed after I had removed it.

Looks like an issue has already been filed over there for this.

[jalvesaq]

It's archived now.

Hi!

I am having some trouble configuring the completion with r_ls...

As far as I have seen, r_ls does not provide diagnostics, right? That's why I am still using r_language_server for diagnostics, but I would like to get the completions from r_ls. If I enable both I get autocompletions from both lsps, so that each entry in the menu is duplicated.

In addition, I have found that r_ls crashes when hovering/providing argument autocompletion for functions with a huge number of parameters (r_language_server works fine with those). And I get:

Warn  02|48| PM Client r_ls quit with exit code 0 and signal 11. Check log for errors: /home/urtzi/.local/state/nvim/lsp.log

Unfortunatelly, lsp.log does not contain further information appart from:

[START][2025-12-04 14:50:28] LSP logging initiated

I am experiencing that with the ectotherm function of NicheMapR:

devtools::install_github("mrke/NicheMapR")
library(NicheMapR)
ectotherm(

And right there I get the "client r_ls quit with ....." message.

Any advice on how to properly configure this would be greatly appreciated.

Sorry for the super long message and thanks for this awesome plugin!

You can put this in your ~/.Rprofile:

# Disable completion from the language server
options(
  languageserver.server_capabilities = list(
    hoverProvider = FALSE,
    signatureHelpProvider = FALSE,
    completionProvider = FALSE,
    completionItemResolve = FALSE
  )
)

I'll look at the crash... thanks for reporting the bug!

[urtzienriquez]

Thanks for the tips to modify r_language_server capabilities! Greatly appreciated!

[jalvesaq]

I tried to install "NicheMapR", but got this error:

Error: processing vignette 'microclimate-model-tutorial.Rmd' failed with diagnostics:

--- failed re-building ‘microclimate-model-tutorial.Rmd’

--- re-building ‘microclimate-monthly-input-example.Rmd’ using rmarkdown

 *** caught segfault ***
address 0xffffffff, cause 'memory not mapped'

Is there another function that makes r_ls crash?

[jalvesaq]

I can replicate the bug. I added the ectotherm function nvimcom with an empty body and now I get the crash.

[jalvesaq]

@urtzienriquez, can you try the branch "fix_bugs"?

[urtzienriquez]

Wow! Fantastic! Yes, that solved the crashing! Thanks a lot!
