I'm trying to save the current relative path of my file and line number into my clipboard. I would like to have application/models/my_model.rb:34

But I don't understand how expand works.

They have this example :

Example:
            :let &tags = expand("%:p:h") . "/tags"

But I failed when I want to combine relative path expand("%:h") and file_name expand("%:t").

:echom expand("%:h:t") . ':' . line(".")  

returns model:34

Any ideas ?

    I don't get it ... %:h is not the relative path - it's (the path - filename). Wouldn't just expand('%') . ':' . line(".") do? For example, I get .vim/vimrc:1 when I run vim .vim/vimrc from ~. – muru Mar 18 '16 at 17:06

You should just use expand('%').

If I do:

cd ~/..; vim ~/.vim/vimrc

Then, in Vim:

:echo join([expand('%'),  line(".")], ':')
muru/.vim/vimrc:1

Or with cd ~/Documents; vim ~/.vim/vimrc:

:echo join([expand('%'),  line(".")], ':') join([expand('%:h'), expand('%:t')], '/')
/home/muru/.vim/vimrc:1 /home/muru/.vim/vimrc

expand('%:h') does not offer any advantages here. Doing expand("%:h") . '/' . expand("%:t") is just going to give you back expand('%'), with the added problem that you lose portability - / is not always the correct separator.

Side note: join() is a convenient function for joining strings with separators. Not necessary here, where we have only two items, but could be useful if you add more strings.

  • I like how you used join() that's a good reminder that this function can be pretty useful. – statox Mar 18 '16 at 22:24

One way to do it to combine expand :

:echom expand("%:h") . '/' . expand("%:t") . ':' . line(".")
