Building a Language by Leandro Ostera (Eng) | JSConfAM19
summary
A tiny color language gets built from grammar to runnable machine with concrete choices: grammar written in Backus-Naur Form, a parser that produces an AST, and semantics given as operational semantics that define sequencing, name binding, and evaluation order. Color creation and addition are implemented (RGB components add and cap at 255), the interpreter applies rules bottom‑up to expand names then add colors, and the demo shows the language working end to end.
