[LRUG] Extending Optparse options in Sinatra?

[Jared Patterson]

Hey Guys,

sinatra: 1.3.2

I seem to have got completely stuck right at the end of building a little app. The app tails a log file, which each line is a monitoring event, xml based, and after making some decisions on the alert, I store them as hash keys and am using Sinatra to respond to a particular route and display all listed alerts (hash keys) stored. The issue is that I want to be able to specify some of my own options, which i'm doing by using Optparse, however Sinatra is already using this for its own options, and i'm confused as to how I can extend these built in options. From posts I have read, seems I need to do the following:

------------------
require 'optparse'
require 'logger'
require 'rubygems'
require 'sinatra/base'
Include Sinatra::Delegator

#
# Classes removed to keep this short
#

# Logger Defaults
logger = Logger.new(STDOUT)
logger.level = Logger::INFO

# Optparser Options
options = {}

OptionParser.new do |opts|
  script_name = File.basename($0)
  opts.banner = "Usage: #{script_name} [options]"

  opts.on('-x')        {       set :lock, true }
  opts.on('-e env')    { |opt| set :environment, opt.to_sym }
  opts.on('-s server') { |opt| set :server, opt }
  opts.on('-p port')   { |opt| set :port, opt.to_i }
  opts.on('-o addr')   { |opt| set :bind, opt }

  opts.on('-l', '--logfilepath', 'Path to EventMonitor log file') do |opt|
    options[:logfilepath] = opt
    puts opt
  end

  opts.on('-v', '--verbose', 'Enable verbose logging') do
    logger.level = Logger::DEBUG
  end

  opts.on_tail('-h', '--help', 'Show this message') do
    puts opts.help
    exit
  end
end.parse!

raise OptionParser::MissingArgument, "logfilepath option is missing?" if options[:logfilepath].nil?

puts options[:logfilepath]
------------------

However, running this app specifying only "-l /path/to/my/log.file", it seems options[:logfilepath] just gets set to "true", any ideas?
