Question

I’ve got a rake task that renames a bunch of stuff in various files. So, if someone at the cmd terminal writes this

 rename:namechange[funk]

the code below should perform the necessary find/replace. My problem is that I can’t get this line to work.

args[:new_name.capitalize]

Any idea why?

namespace :rename do

    desc 'changes the name of the app'
    task :changename, :new_name do |task, args| 
      args[:new_name.capitalize]
      # change any instances of the term "framework" to the new name of the app   
      #for testing, just change these: file_names = ['config/environment.rb'] #['config/environments/test.rb', 'config/environments/production.rb', 'config/environment.rb']
      file_names = ['app/helpers/application_helper.rb', 'app/views/pages/home.html.erb', 'rakefile', 'config/application.rb', 'config.ru', 'config/database.yml', 
                    'config/environments/development.rb', 'config/environments/test.rb', 'config/environments/production.rb', 
                    'config/environment.rb', 'config/initializers/secret_token.rb', 'config/initializers/session_store.rb', 'config/routes.rb', 
                    'spec/controllers/pages_controller_spec.rb']
      file_names.each do |file_name|
        text = File.read(file_name)
        File.open(file_name, "w") { |file| file << text.gsub("Framework", args[:new_name]) }
      end   
    end     
end

UPDATE: I had trouble with “.capitalize” because it automatically put any character after the first as a lowercase letter. Ultimately, I arrived at this:

      args[:new_name][0] =  args[:new_name].capitalize[0]

Did you mean to write one of these:

args[:new_name].capitalize!
args[:new_name] = args[:new_name].capitalize
