[Capistrano] Re: How to acquire name of top-level task in an after hook?

[Jamis Buck]

The *simplest* thing is to just show the entire command-line that was used:

  command_line = $0 + " " + ARGV.join(" ")

By way of explanation:

I've got this simple email notifier task below that runs after my main
deployment tasks, and I'd like it to show the command or even the
command-line that kicked everything off.  The attempt below uses some
fancy code that I blatantly cribbed from the show.me task in the
excellent capistrano-mailer plugin, but I find it doesn't work, at
least not in an after hook.  It just returns "email_notify" instead of
"deploy" or "deploy:migrations"

end

after "deploy:migrations", "email_notify"

I'm a relative Ruby novice, so I'd be happy with the original raw
cmdline or just the top-level task.

Thanks,

PS: I'm sending from the servers via ssmtp (which simulates sendmail)
because it seemed easier to configure a few servers than to verify
outbound email worked for the variety of developer client boxes I have
to support.
