Open Yegorov opened 2 years ago

Yegorov commented 2 years ago

Hello! It possible use StringIO in Ox::Builder?

require 'ox'
io = StringIO.new
b = Ox::Builder.io(io, indent: 2) # Here I get an exception: `io': expected an IO that has a fileno. (IOError)
10.times do
  b.element('node') do
    b.text('value')
  end
end
b.close
io.to_s

Currently only files are supported. I'll looking into supporting anything that can be written to. Sorry for being slow to respond.

It would be too much of a change to support StringIO with little gain. Did you know you can create a new Builder without and io and it will build a string? Line 1472 of the test.rb file is an example of that.
