In my .vimrc
file, I would like to store in a variable the result of an external command, in my case:
$ echo $LANG
So that my .vimrc
file would have :
let language = output(!echo $LANG)
if language == 'en'
nnoremap <somekey> <ohanotherkey!>
end if
So far I couldn't find how to do it. I've found that in command mode, :read !echo $LANG
would insert in my current file the content I am looking for. But I don't know how to write it down in a .vimrc
file.
