@lbfalvy can you please get this down to a minimal example that can be used to reproduce the error. Also, it would be good to know the exact version of...

Thank you for the extra info!

Because this issue involves tabs, I think this is related to https://github.com/rust-lang/rustfmt/issues/4968#issuecomment-949461340

From local testing with rustfmt 1.8.0-nightly (d97c4fb3e2 2025-01-13) this snippet from https://github.com/rust-lang/rustfmt/issues/6442#issuecomment-2587385011 still panics with `hard_tabs=true`

I see. Either way, the MCVE you provided still panics, and I think that's a good enough reason to keep the issue open

Just to clarify `annotate-snippets` used to take character offsets. [As of a more recent release it uses byte offsets](https://github.com/rust-lang/rustfmt/pull/6391#issuecomment-2471781526). I Agree with your assessment of the underlying issue though.

running `rustfmt --print-config default` is exhaustive, and even includes the default for nightly only options that you can't set on stable. I'm not sure what you mean about overwriting the...

Thanks for reaching out. If I understand correctly, you'd like an option to enforce a consistent number of blank lines between various control flow constructs. Let me know if I've...

You might want to familiarize yourself with how functions get rewritten. That starts in `FmtVisitor::visit_fn`. `visit_block` is called next, and internally that makes a call to `walk_block_stmts`. There's more to...

@kornelski I'm not sure if it'll help in all cases, but maybe some of rustfmt's more granular width configurations could help you out here. I'm linking to [use_small_heuristics](https://rust-lang.github.io/rustfmt/?version=v1.7.1&search=#use_small_heuristics), which links...
