When a Writer supports streams, also allow it to simply support a file

# File lib/io_streams/reader.rb, line 13
def self.file(file_name, original_file_name: file_name, **args, &block)
  ::File.open(file_name, "rb") { |file| stream(file, original_file_name: original_file_name, **args, &block) }
end

# File lib/io_streams/reader.rb, line 24
def initialize(input_stream)
  @input_stream = input_stream
end
open(file_name_or_io, **args, &block) click to toggle source

For processing by either a file name or an open IO stream.

# File lib/io_streams/reader.rb, line 18
def self.open(file_name_or_io, **args, &block)
  file_name_or_io.is_a?(String) ? file(file_name_or_io, **args, &block) : stream(file_name_or_io, **args, &block)
end

When a Reader does not support streams, we copy the stream to a local temp file and then pass that filename in for this reader.

# File lib/io_streams/reader.rb, line 5
def self.stream(input_stream, **args, &block)
  Utils.temp_file_name("iostreams_reader") do |file_name|
    ::File.open(file_name, "wb") { |target| ::IO.copy_stream(input_stream, target) }
    file(file_name, **args, &block)
  end
end
