Background
Ensure
Ruby provides begin/rescue/ensure which is rather analogous to try/catch/finally in Java.
note: although coincidental, it is rather fitting that this reference covers begin/rescue/ensure with ensuring to close an opened file as its example. Ensuring to close an opened file is the canonical example for this sort of feature.
Yield
Code To Implement
open_yield_close
| file: | src/main/ruby/text_file_writer/text_file_writer.rb |  |
| class: | TextFileWriter | |
| superclass: | Object | |
| methods: | open_yield_close(path) |
Client
TextFileWriter.open_yield_close(path) do |file|
file.write("<html><body><h1>#{Time.now}</h1></body></html>")
end
