REPL autocompletion - some minor bugs still occur after merging #1038.

Debug adapter definition and debug configuration

local home=os.getenv( "HOME" )
local gdb_path = home .. "/.config/nvim/gdb/extension/debugAdapters/bin/OpenDebugAD7"

local dap = require('dap')

dap.adapters.cppdbg = {
  id = 'cppdbg',
  type = 'executable',
  command = gdb_path,
}

dap.configurations.cpp = {
  {
    name = "Launch file",
    type = "cppdbg",
    request = "launch",
    program = function()
      return vim.fn.input('Path to executable: ', vim.fn.getcwd() .. '/', 'file')
    end,
    cwd = '${workspaceFolder}',
    stopAtEntry = true,
    setupCommands = {
        {
            text = '-enable-pretty-printing',
            description =  'enable pretty printing',
            ignoreFailures = false
        },
        {
            text = 'set follow-fork-mode parent',
            description =  'follow parent process',
            ignoreFailures = false
        },
        {
            text = 'set detach-on-fork off',
            description =  'disable detach on fork',
            ignoreFailures = false
        },
    },
  },
}

Debug adapter version

vscode-cpptools v1.17.5

Steps to Reproduce

1) In the REPL window type -exec i bre: 2) Press <C-x><C-o> to trigger autocompletion: 3) Press <CR> to confirm the suggestion:

Expected Result

The completed command should be exec -i breakpoints.

Actual Result

An additional random(?) character is appended to the end of the command.

What are your complete and completeopt settings? I'm not seeing any additional characters. -exec i bre completes to -exec i breakpoints for me.

[Alexey104]

What are your complete and completeopt settings?

complete=.,w,b,u,t
completeopt=menu,preview

-exec i bre completes to -exec i breakpoints for me.

Yes, it completes correctly for me too, but after pressing Return a garbage character is appended at the end. I also see this behavior when setting breakpoints at some (but not all) functions.

[mfussenegger]

I tried it again with your options and it still works fine for me. Return doesn't append any garbage characters.

[Alexey104]

Hmm... Maybe some of my other plugins causes this. When I have more time I'll try to disable everything besides nvim-dap and test. I'll report back if I find anything.

[Alexey104]

Ok, Coc.nvim plugin was the culprit, specifically these lines:

if exists('*complete_info')
    inoremap <expr> <cr> complete_info()["selected"] != "-1" ? "\<C-y>" : "\<C-g>u\<CR>"
else
    inoremap <expr> <cr> pumvisible() ? "\<C-y>" : "\<C-g>u\<CR>"
endif

Sorry for wasting your time, I should've checked with clean config right away before reporting a bug.
