Depending on your language, creating a grammar and then creating a recursive descent parser based on it is a perfectly reasonable approach, and that's what most major programming languages do. For experimental stuff like https://hyperscript.org https://hyperscript.org I wing it a bit more, but that's the flavor of that language.
