[Feature request] Show buffer number in the buffer in the above buffer list statusline.

[wsdjeg]

Airline team:
thanks for all your work.this plugin make vim works better.
I need a new feature,shou buffer number in the buffer list line.By defaue if I edit more than one file.I will see buffer list line on the above of the screen.
for example

README.md >help.txt >

I want the list shown like irssi's channel

1:README.md >2:help.txt>

the first number is the buffer number.

will this feature be added to airline?

thanks

So basically you want :let g:airline#extensions#tabline#buffer_idx_mode = 1?

[wsdjeg]

thanks,it works ,but the number is too small.

can I let the list shown like this?
1: README.md > 2: init.vim >

[wsdjeg]

and I use ctrlp open the next two files,so the buffer number is 3 and 4,buffer 2 is ctrlp buffer.so I think the number shown in the pic above is not buffer number.

[chrisbra]

you can check with :ls buffer names should be the same

[wsdjeg]

I use :buffers，and it is not same.I will have a try with :ls tonight

[wsdjeg]

@chrisbra I use ctrlp to open the file,so the number is different with the num shown in the buffer list line.

see #1121

[wsdjeg]

@dragonxlwang please my picture above.the buffer number in the tab line is wrong.it should be 1,3 not 1,2

[dragonxlwang]

yes, the thing you showed above is buffer "index", not buffer number, which you can check with bufnr/buffers

both #1121 and the doc address this if I understand your issue correctly.

[wsdjeg]

the second pic is output of buffers.so you man bufnr will show different result?
ok will check tonight

[dragonxlwang]

No!!

buffers and bufnr shows the same thing!!

for your purpose, you DON'T want to use buffer_idx_mode.

Instead, use:
let g:airline#extensions#tabline#buffer_nr_show = 1

[wsdjeg]

I see . sorry for this issue
