Hi All,
According to the document of expand, "expand('%:p')" should be able to give
full path of current buffer. This works properly when use vim to open an existing file or
create a new file in an existing directory. But If I execute this command:
gvim a/a.c
where a is a non-existing directory. Then I run ":echo expand('%:p')", it gives
'a/a.c', which is not what I expected. Other modifiers just work as expected except '%:r'.
Anyone have any ideas?
Thanks!

In this case, trying to write the file will answer "a/a.c: E212 Cannot
open file for writing", showing that there is *no* path to the file. But
after creating a subdirectory ./a in the current directory,
expand('%:p') gets a sensible value, and the write (if attempted) succeeds.
On Unix you might try
:exe '!mkdir -pv' expand('%:h')
:w
if you really want to save the file under that name. (Of course it will
fail if you don't have the necessary directory-creation permissions.)
Hi Tony,
Thanks for your reply.
I have noticed that I can not write to disk if I create a new file in a
non-existing directory; what I am concerning is the unexpected behavior
of `expand('%:p')`. I am currently encountering an issue in my plugin: I
call `expand('%:p')` to obtain the full path, but in the given case
above, I would get a truncated path. So I think this behavior should not
be expected. Do you think so?
Thanks,
Hong
