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 ? 3 Good to know (you picked “Textmate”).

Or build a complex menu using a block. Announce a new release: 1. ruby-talk 2. Blog 3. Twitter 4. Exit ? 2 Posting to blog.you.com! 1. ruby-talk 2. Twitter 3. Exit ? 1 Sending mail! 1. Twitter 2. Exit ? 2

There is also a list() function for display stuff in a compact list For example, here’s a list of the available tasks: .hg/branch ChangeLog check_extra_deps check_manifest clobber clobber_docs commit-msg.txt config_hoe default demo deps:list doc gem generate_key hg:ci hg:commit hg:prep_release hg:pull hg:push_without_confirmation hg:update newb package pkg/hoe-highline-0.0.1.gem pkg/hoe-highline-0.0.1.tgz pre prerelease rcov rcov_overlay release_sanity release_to ridocs
