I have a script like
OptionParser.new do |opts|
opt.on("-h","--help","help") do
puts opts
end
end.parse!
But whenever I call rails runner my_script.rb --help
it shows me help for the rails runner and not my script. Is there a way that I can prevent rails runner from swallowing up this option?
I am afraid you cannot do this with runner - runner first searches for its own options and in case of --help
or -h
it prints the help and exits before even checking whether your script exists or not:
# Railites: lib/rails/commands/runner
opts.on("-h", "--help",
"Show this help message.") { $stdout.puts opts; exit }
You can however get around this by simply not using runner at all and writing pure ruby script:
#!/usr/bin/env ruby
require 'optparse'
environment = 'development'
OptionParser.new do |opts|
opt.on("-e", "--environment") do |v|
environment = v
end
opt.on("-h","--help","help") do
puts opts
end
end.parse!
# RAILS_ENV is used by environment.rb file to load correct configuration
ENV['RAILS_ENV'] = environment
# Load your rails application
require_relative "../config/environment.rb"
puts User.count # Your code here
