Yank current file path and line number into system clipboard

Question

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 ?

Answer 1

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.

One way to do it to combine expand :

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