I’m working on Ruby program that will have a resource directory for
storing configuration, logging information, etc. I’ve used the
END and DATA trick in my main ruby program to store some sane
defaults for the resources directory if this is the first time the
program has been run by a user.
#!/usr/bin/env ruby
require ‘mylib’
unless File.exist?(ENV[‘HOME’] + ‘.myrc’)
File.open(ENV[‘HOME’] + ‘.myrc/defaults’, ‘w’) do |fd|
fd.write DATA.readlines
end
end
use defaults here
END
hash_key_1 : 1
hash_key_2 : 2
etc : and some more
This works very well when my application is run directly. But when
installed via gems a new ruby script is created that loads my
executable script 
This causes the END keyword in my ruby
script to stop working, and the DATA constant is not set.
Is there a way to tell the gem installer “Hey, quit being so smart and
just install my executable file without wrappering it with your own
ruby script”.
Blessings,
TwP

Something like:
File.read(FILE).split(“END”).last
But why not store it in a separate config file?

I’m trying to be clever in the way I bootstrap this config file into
existence. Using END and DATA seemed very Rubyish and clever.
Alas that gems are smarter than I am.
I just dumped it into a here doc in the file. Just as effective.
There is a way to tell gem not to create a wrapper, but the user has
to do it when they install the gem …
gem install --no-wrapper mygem
However, gem is not honoring the executable bit in the file permission
So the symbolic link to my executable still does not work because
the executable is no longer executable .
