Handling mails on a text editor

A text editor is perfect for mail handling because mails consist of text. Ruby is perfect for text editing because it's so powerful.

In this talk, I introduce Textbringer, a text editor written in Ruby, and Mournmail, a message user agent implemented as a plugin of Textbringer, and I tells the fun of text editing and mail handling.

I also talk about Law, Chaos, and the Cosmic Balance through the design and implementation of Textbringer and Mournmail.
