Disabling autotrigger causes error

[medwatt]

I haven't tested it extensively, but the issue I reported is now gone.

Could you share some additional info on how to reproduce this issue? Where did you put that code? What is the exact error message? Which snippet definitions are you using? Possibly relevant: your Neovim version. I added this to my .vimrc (and I can confirm A snippets are not triggered automatically anymore) but I can't reproduce this issue.

[medwatt]

I am using Neovim version 0.6. The code I provided in the first post is inside the config file I have for ultisnips.

Here's my cmp config:

local present, cmp = pcall(require, "cmp")

local has_any_words_before = function()
    if vim.api.nvim_buf_get_option(0, "buftype") == "prompt" then
        return false
    end
    local line, col = unpack(vim.api.nvim_win_get_cursor(0))
    return col ~= 0 and vim.api.nvim_buf_get_lines(0, line - 1, line, true)[1]:sub(col, col):match("%s") == nil
end

local press = function(key)
    vim.api.nvim_feedkeys(vim.api.nvim_replace_termcodes(key, true, true, true), "n", true)
end

cmp.setup {

    snippet = {
        expand = function(args)
            vim.fn["UltiSnips#Anon"](args.body)
        end,
    },

    completion = {
        completeopt = "menu,menuone,noselect",
        keyword_length = 1,
    },

    sources = {
        { name = "ultisnips" },
        { name = "nvim_lsp" },
        { name = "buffer" },
        { name = "path" },
    },

    mapping = {


        ["<C-e>"] = cmp.mapping.close(),
        ["<CR>"] = cmp.mapping.confirm({ behavior = cmp.ConfirmBehavior.Replace, select = true }),


        ["<C-Space>"] = cmp.mapping(function(fallback)
            if cmp.visible() then
                if vim.fn["UltiSnips#CanExpandSnippet"]() == 1 then
                    return press("<C-R>=UltiSnips#ExpandSnippet()<CR>")
                end

                cmp.select_next_item()
            elseif has_any_words_before() then
                press("<Space>")
            else
                fallback()
            end
        end, {
        "i",
        "s",
    }),

    ["<Tab>"] = cmp.mapping(function(fallback)
        if vim.fn["UltiSnips#CanJumpForwards"]() == 1 then
            press("<ESC>:call UltiSnips#JumpForwards()<CR>")
        elseif cmp.visible() then
            cmp.select_next_item()
        elseif has_any_words_before() then
            press("<Tab>")
        else
            fallback()
        end
    end, {
    "i",
    "s",
}),

["<S-Tab>"] = cmp.mapping(function(fallback)
    if vim.fn["UltiSnips#CanJumpBackwards"]() == 1 then
        press("<ESC>:call UltiSnips#JumpBackwards()<CR>")
    elseif cmp.visible() then
        cmp.select_prev_item()
    else
        fallback()
    end
end, {
"i",
"s",
    }),
},
}

I am using the default configuration for ultisnips. With the autotrigger disabled, when I am insert mode and press any character, I get the following .

Thank you. Possibly a duplicate of #46? Are you using the latest version of this plugin? Also, we have now added recommended mapping functions you can call - see readme (they do the same as your code).

[medwatt]

I just updated and tried the recommended settings. I'm still getting the same error.

[smjonas]

Ok this is weird. Just to be 100% sure: everything works correctly when autotrigger is enabled? I will look into it.

[medwatt]

Have a look at the video to see exactly what is going on. While experimenting, I noticed that if I press the tab key by itself while in insert mode, the problem does not occur

Could you try this PR? #51
I suspect it is some kind of loading order problem, seems like UltiSnips is not available yet when cmp_nvim_ultisnips is ready.
So I tried to source the UltiSnips file as cmp_nvim_ultisnips starts.

[smjonas]

Wow I'm a bit surprised that it worked, thanks for testing!
