Mapping tab and S-tab problem

[JoseConseco]

Hi when I try to map tab to jump next like so: if vim.fn["snippy#can_jump(-1)"]() == 1 then I get error: Is there guide how to map nvim cmp for snippy with tab(tab) and shift tab (prev)?

Hi! I think there's a mistake in your code. It should be if vim.fn["snippy#can_jump"](-1) == 1 then, or you could use the Lua version:

local snippy = require("snippy")
if snippy.can_jump(-1) then
  ...

Please let me know if it still isn't working for you.

As for the guide, there's currently none specifically for cmp, except for what is said in this project's readme, but I'll see if can come up with something specific for Lua and/or cmp.

thanks, the fix worked ok. Now I hit another problem where cmp can correctly detect if selected entry is snippy snippet:

    if cmp.visible() then
        if cmp.core.view:get_selected_entry() then
            if vim.fn["snippy#can_expand"]() == 1 then
                print('can jum')
                return vim.fn.feedkeys(t("<C-R>=<Plug>(snippy-expand-or-next)<CR>"))
            else
                print('cannot')
                vim.fn.feedkeys(t("<cr>"), "n")
                        end
        else
            vim.fn.feedkeys(t("<C-e>"), "n")
        end
    else
        cmp.complete()  -- invoke popup
    end

vim.fn["snippy#can_expand"]() - does not seem to correctly detect that selected item in cmp popup is snippy item.. For now I will wait until there is more online help, before jumping into snippy. Plugins is great and I hope it will get more people attention soon!
