When looking at the docs for an object (via textDocument/hover),
there is often a url in there that I would like to open.
This very gross plugin provides a function to do so, at least in the very narrow case where your LSP server is returning markdown content and the url you care about is the first one. This is usually the case with golang, which is what I'm really targeting here.
Add this plugin in the usual fashion and you will be rewarded with an OpenHoverDocURL function.
I recommend mapping it to gx, which is usually used for opening files with netrw or something,
I didn't read the docs that carefully
nnoremap gx :OpenHoverDocURL<cr>
