hoe_highline

Description

A Hoe plugin for building interactive Rake tasks.

Hoe-highline, as you might have guessed from the name, adds prompting and displaying functions from the HighLine gem to your Rake environment, allowing you to ask questions, prompt for passwords, build menus, and other fun stuff.

Installation

gem install hoe-highline

Usage

# in your Rakefile

Hoe.plugin :highline

Hoe.spec 'mygem' do

    # Configure the highline terminal to your liking
    highline.wrap_at = :auto  # Auto-wrap output

end

# Generate an email, show it, confirm they want to send it, then prompt
# for a SMTP connection information before sending
task :send_email do
    message = generate_email( :full )
    say "About to send this:"
    say( mail )

    if agree( "Okay to send it? " )
        require 'socket'
        require 'net/smtp'
        require 'etc'

        username = ask( "Email username: " ) do |q|
            q.default = Etc.getlogin  # default to the current user
        end
        password = ask( "Email password: " ) do |q|
            q.echo = '*'  # Hide the password
        end

        say "Creating SMTP connection to #{SMTP_HOST}:#{SMTP_PORT}"
        smtp = Net::SMTP.new( SMTP_HOST, SMTP_PORT )
        smtp.set_debug_output( $stderr )
        smtp.esmtp = true
        smtp.enable_starttls

        helo = Socket.gethostname
        smtp.start( helo, username, password, :plain ) do |smtp|
            smtp.send_message( message, email_from, *email_to )
        end
    else
        abort "Okay, aborting."
    end
end

There is also a 'demo' task in this library's Rakefile that has a few ideas for things you might want to do. Running it looks like this:

hoe-highline Demo

You can prompt for a yes-or-no answer with agree()
Know what I mean (nudge, nudge, wink, wink)? [yn] y
What's it like?

You can ask for input with ask()
What could be better than that? Nothing!
Actually, that was a rhetorical question, but you answered: "Nothing!"

You can also ask() for things like passwords with a little configuration
Super sekrit password: **********
Okay, using your 10-character password for something nefarious...

You can also use choose() for building a menu.
What editor do you prefer?
1. Emacs
2. vi
3. Textmate
4. pico
5. RubyMine
6. FreeRIDE

Good to know (you picked "Textmate").

Or build a complex menu using a block.

There is also a list() function for display stuff in a compact list

.hg/branch                    ChangeLog
check_extra_deps              check_manifest

deps:list                     doc
gem                           generate_key
