In this prep session for RubyConf Taiwan × COSCUP 2025, I aimed to help everyone break through their mental block and get an initial taste of how Ruby’s underlying lexer and parser work — all within a limited time, using extremely simple explanations and the ㄅㄆㄇ (Bopomofo) phonetic symbols familiar to people in Taiwan.
I also gave a brief introduction to lightweight Ruby runtimes, which are still less familiar to many in Taiwan, and wrapped up by sharing about Code Party — an event I had the honor of hosting for the first time locally.
