    I think I agree about the testing and labor of complicated translation rules.

    But it doesn't appear that almost every pretty printer uses the Wadler pretty printing paper. It seems like MOST of them don't?

    e.g. clang-format is one of the biggest and best, and it has a model that includes "unwrapped lines", a "layouter", a line break cost function, exhaustive search with memoization, and Dijikstra's algorithm:

    The YAPF Python formatter is based on this same algorithm -

    The Dart formatter used a model of "chunks, rules, and spans"

    It almost seems like there are 2 camps -- the functional algorithms for functional/expression-based languages, and other algorithms for more statement-based languages.

    Though I guess Prettier/JavaScript falls on the functional side.

    I just ran across this survey on and it seems to cover the functional pretty printing languages influenced by Wadler, but functional style, but not the other kind of formatter ("Google" formatters perhaps)
