Are there any languages where code-style is required to be a certain way? or it won't compile. I mean full authoritarian about everything, not just based around

Are there any languages where code-style is required to be a certain way? or it won't compile. I mean full authoritarian about everything, not just based around white-space like python.

Some have little that can differ, such as assembly, but not that I know of at least. Some define a "proper" way, though (PEP-8, gofmt, and doesn't rust also have a rustfmt?).

  rustfmt exists, and has come a long way recently, but is not quite ready to be distributed with Rust by default yet. Soon though!

    I think the original question was about full-on enforcement of style rules as grammatical rules, by the compiler, as proposed by Ken Arnold in his 2004 essay Style is Substance [1]. AFAIK nothing like that is remotely on the cards for rustfmt. [1] http://www.artima.com/weblogs/viewpost.jsp?thread=74230 http://www.artima.com/weblogs/viewpost.jsp?thread=74230

      Absolutely.

The gnat Ada compiler has style warnings, which, together with -Werror, ensure that you don't write non-conforming code.

Yes, old fixed-format languages like FORTRAN and RPG (the older versions). Everything had to be written in specific columns, due to their punched card heritage.

  Fixed-format FORTRAN isn't actually that rigid. The first six columns have special semantics, but apart from that, the compiler is not going to enforce a certain style.

python indent wrong and it doesn't run.

Go uses gofmt, which pretty much achieves what you're looking for. Lisp code, emacs generally will generally just clean up idiomatically though that's less what you're looking for.

This is where Go really dropped the ball. They had the perfect opportunity to move lint and fmt (and vet and the rest) into the compiler. I don't for the life of me understand why they did not.

Many teams configure their CI systems to fail builds if they don't pass style checks. This can be great if there's some situational flexibility since no autoformatter is smarter than a human that knows the code, but terrible if there's a formatter (like prettier) that defines only one true format and sometimes gets things horribly wrong.
