Convert templates in files to use parameters macros

migrate.rb

Dir.glob('./**/*.erb').each do |template|
  puts "Found #{template}"
  content = File.read(template)
  content = content.gsub(/@host\.param_true\?\((.*?)\)/, 'host_param_true?(\1)')
  content = content.gsub(/@host\.param_false\?\((.*?)\)/, 'host_param_false?(\1)')
  content = content.gsub(/@host\.params\[(.*?)\]/, 'host_param(\1)')
  content = content.gsub(/@host\.info/, 'host_enc')
  File.write(template, content)
end

hi, do you have a readme file with this script ? How should I use it ?
I want to convert my provisioning template syntax to the new one on my Satellite 6.6 (https://access.redhat.com/documentation/en-us/red_hat_satellite/6.6/html/upgrading_and_updating_red_hat_satellite/post_upgrade_tasks#post_upgrade-updating-templates-parameters)

you put it to the directory with templates, then you run it ruby migrate.rb. It will go over every *.erb file in that dir and update it. On existing installations, templates are in database, so you would need to export them, fix them, import them back. For that, foreman_templates plugin can be used.
