Text File Writer Assignment
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.
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
