textEdit completion item property is not resolved lazily

[ypomortsev]

rust-analyzer 2024-10-07 and newer does not send the textEdit completion property by if the client can resolve it lazily, introduced in rust-lang/rust-analyzer#18167.

cmp-nvim-lsp includes textEdit in its default_capabilities but does not seem to resolve it lazily, breaking completion:

Observed with textEdit in capabilities:

(pressing Enter to complete)

Expected, without textEdit in capabilities:

(pressing Enter to complete)

Same issue on my end. A workaround for now is to use the 2024-09-30 release of rust-analyzer.
For those using mason to handle language servers, you can uninstall the current version of rust-analyzer and then run :MasonInstall rust-analyzer@2024-09-30

Another workaround is to not override the default capabilities with require 'cmp_nvim_lsp'.default_capabilities() for rust_analyzer. Not sure about the downsides, though.

[coder3101]

Actually default_capabilities() take an override table which can be used to override some capabilities. In our case, resolve support properties can be overridden as

require("cmp_nvim_lsp").default_capabilities(
    {
        resolveSupport = {
            properties = {
                "documentation",
                "detail",
                "additionalTextEdits",
                "sortText",
                "filterText",
                "insertText",
                "insertTextFormat",
                "insertTextMode"
            }
        }
    }
)

imo this is better than not having to override the complete cmp default capabilities.

Doing

local capabilities = require("cmp_nvim_lsp").default_capabilities(
    {
        resolveSupport = {
            properties = {
                "documentation",
                "detail",
                "additionalTextEdits",
                "sortText",
                "filterText",
                "insertText",
                "insertTextFormat",
                "insertTextMode"
            }
        }
    }
)

vim.g.rustaceanvim = {
  server = {
    capabilities = capabilities,
...

with the newest ra version didnt work for me

Repro with minimal config:

init.lua

local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    "git",
    "clone",
    "--filter=blob:none",
    "--single-branch",
    "https://github.com/folke/lazy.nvim.git",
    lazypath,
  })
end
vim.opt.runtimepath:prepend(lazypath)

require("lazy").setup({
  {
    'williamboman/mason.nvim',
    dependencies = {
      { 'neovim/nvim-lspconfig' },
      { 'williamboman/mason-lspconfig.nvim' },
    }
  },
  {
    'hrsh7th/nvim-cmp',
    dependencies = {
      { 'hrsh7th/cmp-buffer' },
      { 'hrsh7th/cmp-nvim-lsp' },
    },
    config = function()
      local cmp = require('cmp')
      cmp.setup({
        sources = cmp.config.sources({
          { name = 'nvim_lsp' },
        }),
        snippet = {
          expand = function(args)
            vim.snippet.expand(args.body)
          end,
        },
        mapping = cmp.mapping.preset.insert({
          ['<C-Space>'] = cmp.mapping.complete(),
          ['<C-e>'] = cmp.mapping.abort(),
          ['<CR>'] = cmp.mapping.confirm({ select = true }),
        }),
      })
    end
  }
})

require('mason').setup()

local mason_lspconfig = require('mason-lspconfig')
mason_lspconfig.setup({
  ensure_installed = { 'rust_analyzer@nightly' },
  automatic_installation = true,
})

local lsp_capabilities = require('cmp_nvim_lsp').default_capabilities(
  {
    resolveSupport = {
      properties = {
        "documentation",
        "detail",
        "additionalTextEdits",
        "sortText",
        "filterText",
        "insertText",
        -- Remove `textEdit` to fix https://github.com/hrsh7th/cmp-nvim-lsp/issues/72
        "textEdit",
        "insertTextFormat",
        "insertTextMode",
      }
    }
  }
)

local lspconfig = require('lspconfig')

lspconfig.rust_analyzer.setup({
  capabilities = lsp_capabilities,
})

Cargo.toml

[package]
name = "cmp-nvim-lsp-72"
version = "0.1.0"
edition = "2021"

1. mkdir cmp-nvim-lsp-72 && cd cmp-nvim-lsp-72 && mkdir src && touch src/main.rs
2. Create init.lua
3. Create Cargo.toml
4. vim -u init.lua src/main.rs
5. Type:
   fn main() {
   Enter
   print
   Ctrl-N (should select println!(…))
   Enter (completes println!(…) but should complete println!(|) with cursor between parens)

Hmm, met the same issue now with the latest version (and I can confirm it is the recently commit will cause this problem).

@VVishion for me what fixed it with the rustaceanvim config is to use vim.lsp.protocol.make_client_capabilities directly.

vim.g.rustaceanvim = {
   server = {
     capabilities = vim.lsp.protocol.make_client_capabilities(),
   }
}

[tan-wei]

@marcelarie It works, thanks.

[sineptic]

For me it works the same as

capabilities = {
    textDocument = {
        completion = {
            completionItem = {
                snippetSupport = false,
            },
        },
    },
},

Now some snippets doesn't work. For example:
"asfd".dbg -> dbg!("asdf")
or
"asfd".ok -> Ok("asdf")

[sineptic]

Also issue doesn't occur if first item selected.

IMHO a very high severity issue. It frequently breaks workflows and often results in unusable completions.
