This is based off #1.

@pedro As per our conversation, I need to extract Devdigest out of bin/devdigest so it can be used outside of the CLI so it's on par with what you've committed to master.

The using the Devdigest class directly should rely on ENV vars. The CLI can make use of prompting for credentials and persisting in ~/.netrc.

@pedro OK. I think we're good. You can move Rakefile to another project which will be pushed to Heroku and keep it mostly identical. You'll need to add devdigest to its Gemfile (once it's pushed, of course), require it, and tweak the call to Devdigest.run.

# changed from './devdigest'
require 'devdigest'

task :digest do
  # defaults to 1 day
  puts Devdigest.run
end

task :daily_digest do
  since = Time.now-24*60*60
  # api changed from run(since) to run(since: since)
  puts Devdigest.run(since: since)
end

task :daily_email do
  case Time.now.wday
  when 0, 6
    puts "Skipping weekend"
    next
  when 1 # monday
    since = Time.now-3*24*60*60
    puts "Monday - fetching activity since #{since}"
  else   # regular weekday
    since = Time.now-24*60*60
    puts "Weekday - fetching activity since #{since}"
  end

  # api changed from run(since) to run(since: since)
  digest   = Devdigest.run(since: since)
  markdown = RDiscount.new(digest)

  # remaining email code identical...
end

Let me know what you think and I can start merging this into master. We can extract bits from `lib/d
