I saw on StackExchange that someone asked about how to see the full path of current file in Vim. I think it would be helpful to write about how I do it.
Temporary solution#
To show the full path of current file, you can press {count}Ctrl-G, that is,
a count bigger or equaling to 1, followed by Ctrl-G. If you press 1<C-G>,
only the full path of the file will be shown. If you press a number bigger than
1, the buffer index of current file will also be shown. For more info, see :h Ctrl-G.
You can also use expand() function to see the full path of current file:
:echo expand('%:p')
In the above command, % is special character which represents the name of
current file. :p is a path modifier which is used to show the full path of
the file. Please see the expand() doc on other types of path modifiers.
Permanent solution#
If you want to show the current file path permanently so that you can see its
path whenever you like. A good place to put the file path is the title
bar. In order to do that,
you need to set the title
and titlestring.
Currently, I am using the following settings:
set title
set titlestring=%{hostname()}\ \ %F\ \ %{strftime('%Y-%m-%d\ %H:%M',getftime(expand('%')))}
It will show the hostname of Vim, then the complete path of the file and followed by last modified time of the file.
The titlestring is just a string. You can use pre-defined modifier to show the
content of various variables and the results of various functions. It seems a
bit complicated. But in fact, it is not so scary. It uses the same syntax as
the statusline (see :h statusline).
In the above setting for titlestring, we first show the hostname of the Nvim
using the hostname()
function. %{} is a special modifier, which will evaluate the expression
inside and subsititute the returned result as a string. %F is a modifier used
to show the full path of the file. The
getftime() function is
used to show the last modified time of the current file.
strftime() function is
used to convert the time to pre-defined format, that is YYYY-mm-dd HH:MM.
The end result is something like the following
