TL;DR: could the code generator implement precedence climbing automatically as an optimization ? Here is the context for my question: I'm working with a fairly complex language grammar generated from...
Found while fuzzing [Tera v1](https://github.com/Keats/tera/tree/v1). The following expression is very slow: https://github.com/Keats/tera/blob/v1/src/tera.rs#L1028 and adding a level of recursion (eg `_(p=__(p=[_(p=__(p=[_(p=[_(p=[_1(p=[_(p=[_1`) will timeout As far as I can see, the issue...

Given the following grammar: ``` a = { "a" ~ b+ | a } b = { "b" } root = { SOI ~ a* ~ EOI } ``` Then,...
## Problem The PrecClimber handles precedence between infix operators, like `a + b * c`, but doesn't handle precedence between prefix or postfix operators, like `-a.b + c`. ## Expectation...
I played with the online editor and wasn't very happy with the error messages. It seems to report only the name of the root rule: `expected bar`, while I would...
