This style can’t be expressed with the current classification patterns.

The best approximation is probably to remove { and } from the default patterns.

The default pattenrs are compatible with both Allman and K&R. Neither Whitesmith nor Gnu can really be expressed ATM.

I’ve been considering ways to improve the indentation system, an obvious improvement would be to drop the somewhat arcanely named classification patterns and instead use a register based system where a match can add/subtract to a register, where a register represents the indent of the current line, future lines, or a “carry register”.

However, the biggest problem with the indent system is hard-wrapped lines and lisp-like languages, so while the above might be a nice improvement, it’s not really solving the real issue.
