On: Writing a recursive ascent parser by hand

[tyingq]

Right. Was responding to "But recursive-descent, if you're going to use it, seems to cry out for tooling"

[barrkel → tyingq]

As I mentioned in an uncle comment, recursive descent permits localised hackery to switch parsing scheme or dynamically fix tricky context-specific grammar constructs, which argues against tooling.

Tooling is still very useful for grammar validation though, and it's the way to go for ad hoc parsing of a simple or new language.

[rejschaap → tyingq]

That was a typo, he meant to say recursive-ascent needs tooling. Recursive-descent parsers can be hand-written quite easily.
