Enable line numbering for directories

Question

When viewing a directory (using :Explore, for example), I would like to see line numbers. I can run :set number after opening the directory, and that works, but I can't get numbering to turn on by default (using e.g. configuration in my .vimrc file).

I have tried adding variations of the following to my .vimrc file, but none seem to work:

:autocmd FileType netrw set number
:autocmd FileType * setlocal number
:autocmd BufEnter * setlocal number

Here is a reference to a similar question regarding numbering for help files. The solution to that question does not work in this case.

Answer 1

According to :help netrw:

 *g:netrw_bufsettings*  the settings that netrw buffers have
            (default) noma nomod nonu nowrap ro nobl

So I would try

" $MYVIMRC
let g:netrw_bufsettings = 'noma nomod nu nowrap ro nobl'
