Method: Thor::Actions#get

Defined in:
lib/thor/actions/file_manipulation.rb

#get(source, *args, &block) ⇒ Object

Gets the content at the given address and places it at the given relative destination. If a block is given instead of destination, the content of the url is yielded and used as location.

get relies on open-uri, so passing application user input would provide a command injection attack vector.

Parameters

source<String>

the address of the given content.

destination<String>

the relative path to the destination root.

config<Hash>

give :verbose => false to not log the status, and :http_headers => <Hash> to add headers to an http request.

Examples

get "http://gist.github.com/103208", "doc/README"

get "http://gist.github.com/103208", "doc/README", :http_headers => {"Content-Type" => "application/json"}

get "http://gist.github.com/103208" do |content|
  content.split("\n").first
end
