That's 54 lines, ignoring wrapping. More than the height of most people's terminals.

I suggest changing it to something shorter, or printing the URL (~ 4000 characters).

Another option is to run a small service (on golang.org or on another domain) that creates shortlinks. The shortlink would be stored in memcache and expire after a few minutes.

Any opinions?

  • Keep as-is
  • Print a long URL
  • Print a short URL using a service on golang.org
  • Print a short URL using a third-party service like goo.gl
  • Who cares? How many people are headless?

What about writing to a temporary file too? If the link is really long, it might make opening it non-trivial too.

I don't think we should make a short url, because the output could in theory contain data that someone considers private or sensitive. Beyond that I have no opinions.

The current readable output seems clear and much better than printing a 4000-char single-line URL. Users can always redirect the output to a file or find some other way to copy (or make the window bigger than 50 lines).
