How do I convert a file mark to a string?

Question

If I for example create a mark inside the file ~/.vimrc with mV.

How do I convert the mark 'V to the path of the file the mark is in?

When I type :marks I can see a list of marks and the corresponding file paths.

Perhaps I can put this list into a string somehow in order to retrieve the file path, but how?

I want to make a function that jumps to the file of the mark at the position where my cursor was last and not at the mark position.

Answer 1

You probably want to look at ":help getmarklist()" which can give you a list of global marks or, if you prefer, local marks of a specified buffer.

However, this sounds like you just want to restore the cursor when you enter a buffer. Have you looked at ":help restore-cursor"? It has this autocmd as an example:

autocmd BufReadPost *
  \ if line("'\"") >= 1 && line("'\"") <= line("$") && &ft !~# 'commit'
  \ |   exe "normal! g`\""
  \ | endif

This just causes your cursor to jump to the last known position within a file whenever you open it for the first time in a Vim session.

Answer 2

Found a way to store the :marks output into a string without using the getmarklist() function

fun! Marklist() abort
  redir => str
  :silent marks
  redir END
  " do something with str here ...
endfun

But in the end i used a different way to achieve my goal:

let fileMarkKeys = [ "A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z" ]
let fileMarkKeysLen = len(fileMarkKeys)
let i = 0 
while i < fileMarkKeysLen
    exe "nnoremap <leader>'" . fileMarkKeys[i] . " '" . fileMarkKeys[i] . "g`\""
    let i += 1
endwhile

I put the above code into my .vimrc
Now when i use a capital mark like <leader>'V it will jump to my vimrc file in the buffer and automatically go the latest cursor position. (and not to the mark position)
