Where define the script_name?

Rails
1

module ActionController
module UrlFor
extend ActiveSupport::Concern

include AbstractController::UrlFor

I have read the rails source.In the actionpack/lib/action_controller/
metal/url_for.rb

def url_options
  @_url_options ||= super.reverse_merge(
    :host => request.host,
    :port => request.optional_port,
    :protocol => request.protocol,
    :_path_segments => request.symbolized_path_parameters
  ).freeze

  if _routes.equal?(env["action_dispatch.routes"])
    @_url_options.dup.tap do |options|
      options[:script_name] = request.script_name.dup
      options.freeze
    end
  else
    @_url_options
  end
end

end
end

I don’t know where define the script_name.I execute the below command

apple@apple:~/rails$ grep --exclude-dir test -r script_name *
actionpack/lib/action_controller/metal/url_for.rb:
options[:script_name] = request.script_name.dup
actionpack/lib/action_dispatch/routing/
route_set.rb: :trailing_slash, :anchor,
:params, :only_path, :script_name]
actionpack/lib/action_dispatch/routing/route_set.rb:
script_name = options.delete(:script_name)
actionpack/lib/action_dispatch/routing/route_set.rb: path =
(script_name.blank? ? _generate_prefix(options) :
script_name.chomp(‘/’)).to_s
railties/lib/rails/commands/plugin.rb:
attr_reader :environment, :script_name
railties/lib/rails/commands/plugin.rb: @script_name =
File.basename($0)
railties/lib/rails/commands/plugin.rb: o.separator "
#{@script_name} plugin install http://example.com/my_svn_plugin\n"
railties/lib/rails/commands/plugin.rb: o.separator "
#{@script_name} plugin install
git://github.com/SomeGuy/my_awesome_plugin.git\n"
railties/lib/rails/commands/plugin.rb: o.separator "
#{@script_name} plugin install -x my_svn_plugin\n"
railties/lib/rails/commands/plugin.rb: o.banner = “Usage:
#{@base_command.script_name} install PLUGIN [PLUGIN [PLUGIN] …]”
railties/lib/rails/commands/plugin.rb: o.banner = “Usage:
#{@base_command.script_name} remove name [name]…”
railties/lib/rails/commands/plugin.rb: o.banner = “Usage:
#{@base_command.script_name} info name [name]…”
railties/lib/rails/commands/runner.rb: script_name =
File.basename($0)
apple@apple:~/rails$

It’s part of the environment you get from rack / your web server
(apache, nginx etc.). I’d check either the rack source or the
documentation for your web server for its precise interpretation.

The script_name is assigned in journey-19defa6acfe8/lib/journe/
router.rb

  unless route.path.anchored
      env['SCRIPT_NAME'] = script_name.to_s + match.to_s
      env['PATH_INFO']   = match.post_match
    end

Mongel has script_name but it isn’t for my wanting.
