# ----
#
# an old version of this monkey patch:
# https://gitlab.com/cleemy-desu-wayo/outvoke/-/snippets/4875484
#
# ----
#
# This is a monkey patch to handle OSC messages whose OSC Type Tag String is
# "T", "F", or "N".
#
# It supports both sending and receiving.  
#
# And it is for osc-ruby 1.1.5.
#
# To use this monkey patch with Outvoke, for example, save this file as
# `osc_ruby_monkey_patch.rb` in the current directory and require it in
# `outvoke.conf.rb` with `require "./osc_ruby_monkey_patch.rb"`.
#
#
# これは OSC Type Tag String が "T" や "F" や "N" であるOSCメッセージに対応
# するためのモンキーパッチです。
#
# 送信側にも受信側にも対応しています。
#
# osc-ruby 1.1.5 のためのものです。
#
# Outvokeでこのモンキーパッチを利用する場合、例えばこのファイルを
# osc_ruby_monkey_patch.rb でカレントディレクトリに保存し、outvoke.conf.rb から
# require "./osc_ruby_monkey_patch.rb" する、といった方法があります。
