How do I get the name and extension of the current file?

Question

Is there a way to get the name and extension of a file using vimscript?

If so I would like the name and extension separately.

Answer 1

From :he filename-modifiers:

    :t      Tail of the file name (last component of the name).  Must
            precede any :r or :e.
    :r      Root of the file name (the last extension removed).  When
            there is only an extension (file name that starts with '.',
            e.g., ".vimrc"), it is not removed.  Can be repeated to remove
            several extensions (last one first).

    :e      Extension of the file name.  Only makes sense when used alone.
            When there is no extension the result is empty.
            When there is only an extension (file name that starts with
            '.'), the result is empty.  Can be repeated to include more
            extensions.  If there are not enough extensions (but at least
            one) as much as possible are included.
Examples, when the file name is "src/version.c", current dir
"/home/mool/vim":
  :p                    /home/mool/vim/src/version.c
  :t                                       version.c
  :t:r                                     version
  :e                                               c

You can use the expand function to expand these and obtain their values:

:let b:baz=expand('%:e')

For example:

$ vim '+ exe ":normal i" . expand("%:t") . "^M" . expand("%:e")' +wqa foo.bar; cat foo.bar
foo.bar
bar

Answer 2

You can use expand(), see :h expand()

In a script you could do this to get file-name:

let file_name = expand('%:t:r')

To get extension you could do:

let extension = expand('%:e')

---

The expand() function can expand wildcards and special symbols. Here I have used % which expands to current file-name.

Answer 3

after some research i found &lt stands for file type in vimscript.

it seems typing :r in vim gives the file name as well. and replacing r with several other letters gives extensions, etc.
