Question

I’m currently modifying a plugin that I like, to suit my needs. I have come across the problem that I need to know in what buffer I’m in, within VimL’s limitations.

I need to be able to refer to the buffer by name, specifically I need to know when I’m within Vim’s own [Command Line] buffer. Which BTW, you can achieve using q:, q/ or q?.

The plugin I’m modifying is the following: https://github.com/jeffkreeftmeijer/vim-numbertoggle

And this is my fork: https://github.com/Greduan/vim-numbertoggle

What I want to do is know when I’m in this specific buffer, called [Command Line] and not use relative line numbers when I’m in it.

Thanks for any help you can provide!

Answer 1

You could check for some options set by Vim when it creates the command-line window.

1. create this file and directories:

   ~/after/ftpugin/vim.vim
   

   What you put in this file is only executed by Vim when you edit a file with the corresponding filetype.

2. add the following self-explanatory code to that file:

   if &buftype == "nofile"
     setlocal number
   endif
   

It works, here. I think that you can easily adapt it to your needs by adding &filetype == "vim".
