Is there a simple way of finding out the current value of a specified Vim setting? If I want to know the current value of, say tabstop
, I can run:
:set tabstop
without passing an argument, and Vim will tell me the current value. This is fine for many settings, but it is no good for those that are either true or false. For example, if I want to find out the current value of expandtab
, running:
:set expandtab
will actually enable expandtab
. I just want to find out if it is enabled or not.
This sort of does what I want:
:echo &l:expandtab
but it seems quite verbose. Is there a quicker way?
Add a ? mark after the setting name and it will show the value
:set expandtab?
Alternatively, the &
symbol can be used to mean "option" - e.g.
let x = &expandtab
echo &expandtab
If you don't remember what setting you want to check, you can view all settings:
:set all
or show each setting, one setting per line:
:set! all
There are also additional vim settings that can be displayed as well, such as:
:highlight

Edit: There is some misunderstanding of my answer. This does not work for any command. But it does work for all the commands listed in the URL above.
