attempt to concatenate local 'v'

I'm runing behind https_proxy, sometime, proxy down.

I, too, am experiencing this issue after using lazy.nvim to install the plugin and authenticating with :Codeium Auth

Same here. Did anyone find a workaround ?

2 months with no commits in this repo, I just gave up and started using GH copilot.
We pay to use this service, there is no excuse for no maintenance.

EDIT You can manually patch the version.json file to use the latest version which does not seem to have this error. See #337

Note that you may need to run :Codeium Auth and :Codeium enable to get things working

This is an alternate, less portable solution, but I'll leave it in to provide more context

The following seems to be a workaround for me using Lazy, since thankfully the latest release https://github.com/Exafunction/codeium/releases/tag/language-server-v1.48.2 does not seem to have this error.

This is quick and dirty but can probably be fixed just by updating https://github.com/Exafunction/windsurf.nvim/blob/main/lua/codeium/versions.json file - note that this will give you a does not match the expected Codeium server stamp error on startup.

-- Helper to invoke a shell script.
-- adapted from https://lazy.folke.io/installation
local do_shell = function(args, message)
  local out = vim.fn.system(args)
  if vim.v.shell_error ~= 0 then
    vim.api.nvim_echo({
      { message .. '\n', 'ErrorMsg' },
      { out, 'WarningMsg' },
      { '\nPress any key to exit...' },
    }, true, {})
    vim.fn.getchar()
    os.exit(1) -- run `nvim -u NONE -U NONE` to debug if you hit this
  end
end

return {
  'Exafunction/windsurf.nvim',
  dependencies = {
    'nvim-lua/plenary.nvim',
    'hrsh7th/nvim-cmp',
  },
  config = function()
    -- TODO: use a script to find the latest version for host OS.
    local download_url = 'https://github.com/Exafunction/codeium/releases/download/language-server-v1.48.2/language_server_macos_arm'
    -- TODO: use the version instead of `custom`
    local bin_dir = vim.fn.stdpath 'cache' .. '/codeium/bin/custom'
    -- TODO: take from the downloaded binary name
    local bin_path = bin_dir .. '/language_server_macos_arm'

    if not (vim.uv or vim.loop).fs_stat(bin_path) then
      do_shell({ 'mkdir', '-p', bin_dir }, 'Failed to create directory for language server')
      do_shell({ 'curl', '-L', '-o', bin_path, download_url }, 'Failed to download language server')
      do_shell({ 'chmod', '+x', bin_path }, 'Failed to chmod +x on language server executable')
    end

    require('codeium').setup {
      tools = {
        -- Specify the language server binary path to avoid using the embedded (out of date) one
        language_server = bin_path,
      },
      -- This is unrelated, but my config
      virtual_text = {
        enabled = true,
        virtual_text_priority = 1,
      },
    }
  end,
}

This is the error I get just using the suggested config, the debug logs with DEBUG_CODEIUM=trace vim I saw the following error:
