terotil / file_join_encoding_workaround.rb

Last active December 17, 2015 23:19

Needed to work around Ruby File.join returning ASCII-8BIT result. Dunno if aligning argument encodings was strictly necessary for my usecase, but I left it in, even though I noticed that UTF-16 and -32 won't work in any case (ArgumentError: string contains null byte). This workaround blows in your face if there is an argument that can't be encod…

	# Work around https://bugs.ruby-lang.org/issues/6104
	if RUBY_VERSION =~ /^1\.9/ && RUBY_REVISION < 34865
	class File
	class << self
	def join_with_encoding_fix(*args)
	target_encoding = args.first.to_s.encoding
	aligned_args = args.map { \|arg\| arg.to_s.dup.encode!(target_encoding) }
	join_without_encoding_fix(*aligned_args).force_encoding(target_encoding)
	end
	alias_method :join_without_encoding_fix, :join

terotil / nda2csv.rb

Created January 10, 2013 21:03

Processor for Nordea machine readable bank statements (NDA format). Functionally minimal, just enough to outline a friendly interface and be able to export main transaction records to CSV, which is further processable to OFX using https://github.com/terotil/ofxify

	require 'date'

	module Nordea
	module NDA
	class Record
	def self.parse(str)
	self.new(str).normalized
	end

	def initialize(str)
