Support for syn::custom_keyword?

[kennykerr]

Maybe I missed it, but I don't see an obvious way to support custom keywords since the crate's only public function expects a syn::File?

Any chance this is possible? Many thanks.

I don't understand what this means. Could you clarify?

I have my own custom Rust-like syntax that depends on syn::custom_keyword for parsing with the syn crate and I'd like to offer the ability to format these Rust-like source files with prettyplease since its mostly just Rust with the addition of a handful of custom keywords.

Right now, I'm having to escape the custom keywords, call rustfmt, and then unescape the result. I figure prettyplease would be less brittle if it supported custom keywords.

Got it. I'd prefer to keep this crate just for formatting syn::File.
