ぼくの考えた最強のRuby新機能案

ぼくの考えた最強のRuby新機能案

野心的な新機能案や、互換性等の理由でおよそ採用されないであろう夢を書き連ねています。

Remove Fixnum and Bignum

Fixnum と Bignum を削除して、Integer クラスに統合する。両者は Flonum のように内部的に切り替えられる。

1 / 2 is Rational

Integer#/ の結果を Rational で返すようにする。 https://bugs.ruby-lang.org/issues/5512#change-37021

Set the default en coding to UTF-8 in powershell. As seen in http://blogs.msdn.com/b/powershell/archive/2006/12/11/outputencoding-to-the-rescue.aspx
$OutputEncoding = New-Object -typename System.Text.UTF8Encoding
[Console]::OutputEncoding = New-Object -typename System.Text.UTF8Encoding

Script to enable IP multicast without using Ethernet broadcast. It uses tc mirred and pedit actions to copy and edit an IP multicast packet to send over multiple Ethernet unicast frames. It requires two network interfaces to work. One is the interface to grab original multicast packets from and the other is to send out modified packets. This is …
#!/bin/sh
[[ -n "$1" && -n "$2" ]] || { echo "Usage: $0 <interface to grab multicast packets from> <interface to send modified packets to> [target MAC address 1] [target MAC address 2] ..."; exit 0 ; }
