echo "Usage: `basename "$0"` [curl_options...] url"

Curl a remote file into vim, setting the filename based on the URL's filename.
If a file extension can't be determined from the URL, .html will be used by
default. If you're just specifying a domain without scheme (eg. benalman.com),
use a trailing / to keep curlvim from using the TLD as the file extension.

The vim executable will be auto-magically determined by stripping any leading
"curl" off this script's filename. For example, call this script "curlgvim"
and gvim will be run. If this naming convention isn't used, the executable
will default to "vim".

tell application "Google Chrome"
  set currentUrl to URL of active tab of window 1

  -- Obviously, you may need to change ~/.scripts/curlmvim in the following line.
  do shell script "bash -l ~/.scripts/curlmvim " & quoted form of currentUrl & " &> /dev/null &"
end tell

Small typo at line 2 of usage.sh: it says “curlmvim” instead of curlvim. Just a heads up.

That's not a typo! The in-script usage instructions say:

The vim executable will be auto-magically determined by stripping any leading
"curl" off this script's filename. For example, call this script "curlgvim"
and gvim will be run. If this naming convention isn't used, the executable
will default to "vim"

Perhaps I could have made it more clear, but who doesn't like a puzzle?

(mvim is the name of the command-line script that comes with MacVim)

I see! Never used MacVim or mvim so I wouldn’t know. Sorry for the false alarm!
