Vim Ultisnips, visual token and system clipboard

Question

I am quite new to vim but I found it to be powerful tool (especially with plugins such as UltiSnips and YouCompleteMe). I quite like the idea of creating personal snippets in conjunction with visual token to perform quick text transformations. However I would like to be able to select some text in web browser, copy it to clipboard and simply type my_snippet in vim to expand my_snippet with text from clipboard as visual token. It would be quite useful but I have no idea how to arrange it. It would be great if somebody can instruct me how to set up vim to do this.

Answer 1

I will try to give you an example, an issue I had for some time. I am constantly trying out new plugins so, copying the github project name like:

 psliwka/vim-smoothie 

And transforming it on:

Plug 'psliwka/vim-smoothie'

Is something problematic, because along with typing the word Plug at the beggining of the line I have to type the single quotes and remove three spaces and one caridge return

     psliwka /
vim-smoothie 

So my snippet has to wrap it all in one go. After some research I ended up with this:

snippet plug "Insert a new plugin on my vimrc" w
Plug '${1:`!v substitute(@+, ' \|\n', '', 'g' )`}'
endsnippet

Some Explanation: The !v part of the snippet means "vim interpolation", so I can use some vim commands. The substitute() command rules are:

where-substitue,  what-substitute, substitution, flags
    |               |                   |          |
    @+            ' \|\n'               ''         g
  clipboard      space or enter      nothing     globally
