Eventually the realization will hit that you’re just trying to approximate what a compiler usually does, but with a regex pattern […] and all you really wanted was type information.

One of the earliest code changes I made with comby removed redund...

I don’t want to write a grammar specification for fuzzing compilers.

I want a shot at crashing the Rust compiler within 24 hours of fuzzing.

I happen to have test programs for the compiler. Let’s just get fuzzing already.

Fuzzing is the process ...

We have color themes for our IDEs. We should have syntax themes for our tools.

Search and Replace commands could look like this.

swap($1, $2) → swap($2, $1)

swap(α, β) → swap(β, α)

swap(🐵, 🍌) → swap(🍌, 🐵)

With Whatever You Want (WYW) syntax, it’s ...

More on that fuzzing effort here. A fun part of that is looking at programs that crash the compilers. Reducin...

As that grew things being unwieldly, and I wanted to partition off the usage documentation and "other things". Another piece of feedback was that the landing pag...
