+
+I've never had any issue with opening links from vim: I have `<leader>y` set up
+in Visual mode to yank stuff into the system-wide clipboard which I can then
+paste into the browser. However, ever since I mapped `<leader>gh` to trigger
+[`:GBrowse`][1] that opens a browser tab instantly, the old "select > copy >
+switch to browser > Ctrl+T > Ctrl+V" flow started to feel... prehistoric. Mr.
+Bright's comment gave me the final nudge to actually go ahead and set it up.
+
+The good folks from the [developer encyclopedia][3] suggested `gx` but for some
+reason, setting `g:netrw_browsex_viewer` [didn't seem to do anything][4] so the
+command would always `wget` the link then tell the browser to open that
+downloaded file. Therefore, I cobbled together this snippet which was adapted
+from those stackoverflow & github threads:
+
+```vimscript
+function! OpenURL()
+  let l:url = matchstr(expand("<cWORD>"), 'https\=:\/\/[^ >,;()]*')
+  if l:url != ""
+    let l:url = shellescape(l:url, 1)
+    let l:command = "!xdg-open ".l:url
+    echo l:command
+    silent exec l:command
+  else
+    echo "No URL found under cursor."
+  endif
+endfunction
+
+nnoremap gl :call OpenURL()<cr>
+```
+
+_(if you're on a Mac, replacing `xdg-open` with `open` will probably
+do the same thing)_
+
+Now whenever I have my cursor on an http(s) url, I can type `gl` from normal
+mode and xdg-open will use my default browser to open it up. This could be
+extended to any other scheme like `mailto` or `ftp` but I don't have any
+practical use for them right now so that will do.
+
+One drawback is if there's a whitespace in the URL (which is bad practice
+anyway), my regex won't match the whole thing. In such cases I'd rather resort
+to good old manual visual mode than try to be clever and make my URL detecting
+logic exponentially more complex. I'd take simple software with obvious, easily
+understood behavior over overcomplicated, (possibly) subtly broken balls of mud
+any day.
+
+By the way, if you looked at my script and got spooked by the idea of executing
+a shell command composed from arbitrary, potentially unsafe input (i.e. text
+file content), don't worry: that's what [`shellescape()`][2] is for.
