Open URL under cursor in Vim with browser

I'm using Twitvim for the first time. Seeing all the URLs in there made me wonder, is there any way to open the URL under the cursor in your favorite browser or a specified one?

Updated: from tpope's tweet today

Press gx. You can customize the browser. On Gnome and Mac OS X it's already use gnome-open/open. Generally you can set g:netrw_browsex_viewer to anything you want.

Original answer:

Don't remember where I get this function. There is a bug with hash (#) in the url, but the function works well enough that I won't bother fixing it.

function! HandleURL()
  let s:uri = matchstr(getline("."), '[a-z]*:\/\/[^ >,;]*')
  echo s:uri
  if s:uri != ""
    silent exec "!open '".s:uri."'"
  else
    echo "No URI found in line."
  endif
endfunction
map <leader>u :call HandleURL()<cr>

Note: If you are not on the Mac, use gnome-open/xdg-open for Linux, or 'path to your web browser' for Windows

If you are using Vim 7.4 or later, in normal mode, put your cursor below the URL, then click gx, the URL will be opened in browser automatic

Solution for people that unloaded netrw

This is a solution for people who removed netrw(:help netrw-noload) in vim/neovim. For example, they use a different file-manager like vim-dirvish

TLDR:

👉 :!open <c-r><c-a>

or map gx:

👉 nmap gx :!open <c-r><c-a>

So just a bit of background:

I was searching for a solution to this problem too since I actually removed netrw from being loaded in vim completely and replace it with vim-dirvish. This plugin has around 500~ LOC, compared to netrw's (11,000+ LOC).

I don't use remote editing much so vim-dirvish is powerful enough to manage my workflow (It's actually faster than netrw ~ the author claims 2x, I feel it's faster than that - it's really instantaneous ⚡) very useful on large codebase/repositories. I even tried it in a 10K file repo, listing files via - still instant! Someone tested vim-dirvish against Nerdtree, you can see the difference.

I dropped vim-vinegar too because vim-dirvish have the - binding anyway, and most of the configuration of vim-vinegar is netrw specifics. It's just doesn't need it. Two birds in one stone!

The beauty of this plugin is it embraces the philosophy of VINE (Vim is not Emacs). Where it leverages the power of other programs in the terminal to do file manipulations, instead of trying to do everything by itself. The important part is how natural these external programs interact with vim. And that is achieve by :Shdo, and it has a convenient key of . (dot command, which is mnemonic for the repeat command), do that on both selection or the actual line on a vim-dirvish buffer. And type !rm for remove, !mv for rename.

Since I disable netrw, (:help netrw-noload) I found myself reaching gx for time to time. I didn't want to load a plugin to get the gx functionality back.

Now for the solution, there's a binding in command mode, ctrl-r then ctrl-a (:help c_CTRL-R_CTRL-A), to paste whatever you have in your cursor to the command line, so if you combine that with :!xdg-open / :!open (for mac), you pretty much set.

There's a reason why :w doesn't have normal bindings. I'm surprised most solution doesn't leverage command workflow, I use ex-command a lot, :s, :g, :v, :argdo, :cdo, and friends. Combining this with different modes, taps the full power of vim. So don't just stay in one mode, try to leverage the full power of vim.

So the full workflow. While you have your cursor on top of the url, is just a single step: 😊

👉 :!open <c-r><c-a>

Notice the ! which indicates leveraging the power of external programs outside of vim. VINE!

If you want the gx functionality back, you can just map using the same command:

• nmap gx :!open <c-r><c-a>

I like to silent my bindings, so adding <silent> and :sil will do the trick (:help :map-silent)

👉 nmap <silent>gx :sil !open <c-r><c-a><cr>

Note on platform-specific programs to open a url:

1. Mac has :!open
2. Linux has :!xdg-open
3. Windows (WSL2) has :!wslview

I use all three platforms and they work great. You can just use one of them for your vim bindings, eg. :!open and just alias in your bashrc/zshrc/fish config the open command to whatever platform-specific program you have.

eg. alias open = wslview

That way, my vimrc stays platform-agnostic, and I'll just deal with the inconsistencies via bashrc/zshrc/fish config.
