- WARNINGS
Injects the given content into a file. Different from
gsub_file
, this method is reversible.Parameters¶ ↑

give :verbose => false to not log the status and the flag for injection (:after or :before) or :force => true for insert two or more times the same content.
Examples¶ ↑
insert_into_file "config/environment.rb", "config.gem :thor", :after => "Rails::Initializer.run do |config|\n" insert_into_file "config/environment.rb", :after => "Rails::Initializer.run do |config|\n" do gems = ask "Which gems would you like to add?" gems.split(" ").map{ |gem| " config.gem :#{gem}" }.join("\n") end

Examples¶ ↑
create_file "lib/fun_party.rb" do hostname = ask("What is the virtual hostname I should use?") "vhost.name = #{hostname}" end create_file "config/apache.conf", "your apache config"
# File bundler/vendor/thor/lib/thor/actions/create_file.rb, line 22 def create_file(destination, *args, &block) config = args.last.is_a?(Hash) ? args.pop : {} data = args.first action CreateFile.new(self, destination, block || data.to_s, config) end
Create a new file relative to the destination root from the given source.
Parameters¶ ↑
- destination<String>
-
the relative path to the destination root.
- source<String|NilClass>
-
the relative path to the source root.
- config<Hash>
-
give :verbose => false to not log the status.
-
give :symbolic => false for hard link.
Examples¶ ↑
create_link "config/apache.conf", "/etc/apache.conf"
# File bundler/vendor/thor/lib/thor/actions/create_link.rb, line 17 def create_link(destination, *args) config = args.last.is_a?(Hash) ? args.pop : {} source = args.first action CreateLink.new(self, destination, source, config) end
Returns the root for this thor class (also aliased as destination root).
# File bundler/vendor/thor/lib/thor/actions.rb, line 99 def destination_root @destination_stack.last end
Sets the root for this thor class. Relatives path are added to the directory where the script was invoked and expanded.
# File bundler/vendor/thor/lib/thor/actions.rb, line 106 def destination_root=(root) @destination_stack ||= [] @destination_stack[0] = File.expand_path(root || "") end
Copies recursively the files from source directory to root directory. If any of the files finishes with .tt, it’s considered to be a template and is placed in the destination without the extension .tt. If any empty directory is found, it’s copied and all .empty_directory files are ignored. If any file name is wrapped within % signs, the text within the % signs will be executed as a method and replaced with the returned value. Let’s suppose a doc directory with the following files:
doc/ components/.empty_directory README rdoc.rb.tt %app_name%.rb
When invoked as:
directory "doc"
It will create a doc directory in the destination with the following files (assuming that the ‘app_name` method returns the value “blog”):
doc/ components/ README rdoc.rb blog.rb
Encoded path note: Since Bundler::Thor internals use Object#respond_to? to check if it can expand %something%, this ‘something` should be a public method in the class calling directory
. If a method is private, Bundler::Thor stack raises PrivateMethodEncodedError.
Parameters¶ ↑
- source<String>
-
the relative path to the source root.
- destination<String>
-
the relative path to the destination root.
- config<Hash>
-
give :verbose => false to not log the status. If :recursive => false, does not look for paths recursively. If :mode => :preserve, preserve the file mode from the source. If :exclude_pattern => /regexp/, prevents copying files that match that regexp.
Examples¶ ↑
directory "doc" directory "doc", "docs", :recursive => false
# File bundler/vendor/thor/lib/thor/actions/directory.rb, line 49 def directory(source, *args, &block) config = args.last.is_a?(Hash) ? args.pop : {} destination = args.first || source action Directory.new(self, source, destination || source, config, &block) end
