Question

I recently run into problems converting a ruby script to .EXE because I had a File.write statement in it. The documentation doesn’t mention the write method but when I do a

pp File.methods

it is there. So should I use File.write? In a normal Ruby script the following works

File.write("test.txt", "test")

But is it good practice and why doesn’t the documentation mention it?

Answer 1

File.write is in fact IO.write (File is a child of IO) which can be verified by monkey-patching:

class IO
  def IO.write
    puts "IO's class method write was called."
  end
end

File.write # outputs "IO's class method write was called."

It is very well in the documentation.

Thus, I see no reason not to use it.
