how to insert filename without the path in vim

问题

I knew that in the insert mode i can insert the filiename with the path using CTRL-R-%.

But i'd like to insert only the filename without the path part. Is there a similar command for that?

回答1:

You can use

<C-r>=expand("%:t")<CR>

See :help filename-modifiers.

Edit

<C-r> is used in insert mode to insert the content of a register. "% is the register that contains the name of the current file.

"= is the expression register, it contains the result of the expression that comes after =:

<C-r>=2+27+6<CR>        --> 35
<C-r>=expand("%:t")<CR> --> file.txt

While in insert mode, you can use

CTRL-R =expand('%:t')
