A parser for Heroku log messages

This parser uses the Parslet to define rules for parsing a log message in the simple key=value format used by Heroku, eg:

at=error code=H12 desc="Request timeout" method=GET path="/foo" dyno=web.3 connect=1ms service=30000ms status=503 bytes=0

Given a message in the above format, the parser returns a hash of the key/value pairs:

whylom

# given an array
words = %w(duck duck goose cry baby cry)

# generate a hash that counts occurrences of each word, eg:
# {"duck"=>2, "goose"=>1, "cry"=>2, "baby"=>1} 

# Method #1
counts = Hash.new(0)
words.each { |word| counts[word] += 1 }

Superhash!

A wrapper for Hash that lets you access keys via dynamic methods (like Ruby's OpenStruct) but also:

• works recursively
• also lets you use Hash methods like [] and keys

Example

whylom

# example class
class State < Struct.new(:name, :code)
  def self.all
    [
      State.new('Alabama', 'AL'),
      State.new('Alaska',  'AK'),
      State.new('Arizona', 'AZ')
    ]
  end
end

  def self.put_copy(source_key, target_key, source_bucket, target_bucket, options = {})

    store(target_key, original, target_bucket, default_options.merge(options))
    acl(target_key, target_bucket, acl(source_key, source_bucket))

This is a Ruby script that enhances the standard git branch listing by organizing and color coding remotes (origin, root, etc).

• Branches whose remote is origin (the default) are listed at the top.
• Branches whose remote is not origin are listed next, with the remote displayed in magenta. This makes it easier to see branches that are shared with other developers.
• A hardcoded list of staging branches are displayed at the bottom in gold.
