How to change the format of tab

[wsdjeg]

here is my airline config
let g:airline#extensions#tabline#show_tab_nr = 1
let g:airline#extensions#tabline#tab_nr_type= 2
let g:airline#extensions#tabline#show_tab_type = 1

if there is only one tab, tabline looks nice.

but if I run :tabnew

I see

I know it is tab_nr . splits format,

but I hope airline support custom format func just like g:airline#extensions#tabline#formatter

[chrisbra]

and the problem is what?

[wsdjeg]

I want to use Unicode icon instead of 1.1

[chrisbra]

where are your unicode symbols from the first screenshot coming from?

[wsdjeg]

It is setting by

    let g:airline#extensions#tabline#buffer_idx_mode = 1
    let g:airline#extensions#tabline#buffer_idx_format = {}
    for s:i in range(9)
        call extend(g:airline#extensions#tabline#buffer_idx_format,
                    \ {s:i : SpaceVim#api#import('messletters').bubble_num(s:i,
                    \ g:spacevim_buffer_index_type). ' '})
    endfor
    unlet s:i

that link does not resolv. Can you update it please?

[chrisbra]

You can use a custom formatter when the tabline is displayed for several tabs. You need to set the variable airline#extensions#tabline#formatter to your version and need to create that formatter of course.

I hav set it to spacevim .
https://github.com/SpaceVim/SpaceVim/blob/dev/autoload/airline/extensions/tabline/formatters/spacevim.vim

but when severls tab is open , the formatter only change the buffer name （tab name）

but the tab number and number of splits can not be changed it is still 2.2
