jump to next tabstop without filling current one

[JoseConseco]

I cant jump to next tabstop, unless I will fill the current one. For example for this snippet:

snippet integer "IntProperty"
$1: bpy.props.IntProperty(name="test", description='', default=${2: 1}, min=0, max=100, subtype='PERCENTAGE')$0

If I want to leave default value at $2, I press < tab > but it wont jump forward to $0 (only using ultiSnip build-in map < c-j > work for jump) . If I enter anything at $2, then I can < tab > jump forward no problem. It feels almost like I can jump only from insert mode (and select mode jump wont work)

My mappings:

    mapping = {
        ['<C-p>'] = cmp.mapping.select_prev_item(),
        ['<C-n>'] = cmp.mapping.select_next_item(),
        ['<S-Tab>'] = cmp.mapping(function(fallback)
            if vim.fn["UltiSnips#CanJumpBackwards"]() == 1 then
                vim.fn.feedkeys(t("<C-R>=UltiSnips#JumpBackwards()<CR>"))
            elseif vim.fn.pumvisible() == 1 then
                vim.fn.feedkeys(t("<C-p>"), "n")
            elseif check_back_space() then
                vim.fn.feedkeys(t("<S-tab>"), "n")
            else
                vim.fn.feedkeys(t("<S-tab>"), "n")
            end
        end, { "i", "s"}),
        ['<Tab>'] = cmp.mapping(function(fallback)
            -- print('can jump ='..vim.inspect(vim.fn["UltiSnips#CanJumpForwards"]()))
            if vim.fn["UltiSnips#CanJumpForwards"]() == 1 then
                vim.fn.feedkeys(t("<C-R>=UltiSnips#JumpForwards()<CR>"))
            elseif vim.fn.pumvisible() == 1 then
                vim.fn.feedkeys(t("<C-n>"), "n")
            elseif check_back_space() then
                vim.fn.feedkeys(t("<tab>"), "n")
            else
                vim.fn.feedkeys(t("<tab>"), "n")
            end
        end, { "i", "s"}),
        ['<C-d>'] = cmp.mapping.scroll_docs(-4),
        ['<C-f>'] = cmp.mapping.scroll_docs(4),
        ['<C-e>'] = cmp.mapping.close(),
        ['<CR>'] = cmp.mapping.confirm({ -- remapped at bottom by autopairs
            behavior = cmp.ConfirmBehavior.Replace,
            select = false,
        }),
        -- ['<C-Space>'] = cmp.mapping.complete(),
        ['<C-Space>'] = cmp.mapping(function(fallback)
            -- print(vim.inspect(vim.fn.complete_info()))
            if vim.fn.pumvisible() == 1 then
                if vim.fn.complete_info()["selected"] ~= -1 then
                    if vim.fn["UltiSnips#CanExpandSnippet"]() == 1 then
                        return vim.fn.feedkeys(t("<C-R>=UltiSnips#ExpandSnippet()<CR>"))
                    else
                        vim.fn.feedkeys(t("<cr>"), "n")
          end
                else
                    vim.fn.feedkeys(t("<C-e>"), "n")
                end
            elseif check_back_space() then
                vim.fn.feedkeys(t("<cr>"), "n")
            else
                fallback()
            end
        end, { "i", "s", }),
    },

I tried to create separate mapping

snoremap <tab> "<C-R>=UltiSnips#JumpForwards()<CR>"

but then using tab on $2 will create double-quote character for no reason (not sure why). I also tried remapping g:UltiSnipsJumpForwardTrigger to tab in ultisnips config, but then in conflicts with tab in cmp. Any ideas what is going on? WHy: if vim.fn["UltiSnips#CanJumpForwards"]() == 1 then vim.fn.feedkeys(t("<C-R>=UltiSnips#JumpForwards()<CR>"))
wont jump to next tab if I wont fill in $2 ?

Thanks for reporting,

I tried to create separate mapping snoremap <tab> "<C-R>=UltiSnips#JumpForwards()<CR>" but then using tab on $2 will create double-quote character for no reason (not sure why)

it should be, then it works

snoremap <Tab> <ESC>:call UltiSnips#JumpForwards()<CR>

I'm investigating why it doesn't work by the current mapping ...

[quangnguyen30192]

Seems as of now, 's' map does not work as it mentioned from nvim-cmp

        ['<Tab>'] = cmp.mapping(function(fallback)
            ...
        end, { "i", "s"}),

you can check like:

:verbose imap <tab>

it has the mapping, but

:verbose smap <tab>

it doesn't have any mapping. (actually, it had the mapping on the first time but I have no idea why the mapping was cleaned up)

For now, you can use as a workaround

snoremap <Tab> <ESC>:call UltiSnips#JumpForwards()<CR>

I will raise this issue with nvim-cmp author

[JoseConseco]

Ok I found the the issue thanks to you and nvim-cmp author (no need to contact him, as this was UltiSnip problem). I will paste the fix here for other people:

we have to use : vim.fn.feedkeys(t("<esc>:call UltiSnips#JumpForwards()<CR>")) For tab jumping to work in both insert and select mode (even though UltiSnip is using two separate mappings - not sure why, but single line above works in nivm-cmp for both modes)

Tab still wont work, but in file linked above I found variable UltiSnipsRemoveSelectModeMappings and bingo - UltiSnip was auto-removing tab mappings. We can disable this in Packer config:

        use {'SirVer/ultisnips', requires='honza/vim-snippets',
            config=function()  vim.g.UltiSnipsRemoveSelectModeMappings = 0  end,}

Now tab mapping is not removed by UltiSnips, and we can jump in both insert and select mode

Hey, thanks, that was a good finding. I will update README for this.
