Feature request: turning it off for a fragment

[michalrus]

Like:

x = 5
-- format: off
y = 6
-- format: on
z = 7

or similar.

Use case: Servant’s types. The API type would be most readable if each :<|> happened on a new line.

Hindent is just a pretty printer. I don't think we should make things become so complex for such a pretty printer.

[michalrus]

Considering:

• it’s a standalone binary
• which you can use to edit files in place (which happens by default, even without a CLI switch!)
• which means many people will use it to auto-format whole projects regardless of which editors are used by their particular developers,

I can’t see why hindent it’s not a good perfect place to have this.

How do you suggest I should do automatic whole-project auto-formatting, while keeping Servant types under control (i.e. not on a single 500-characters-long line)?

Formatters for other languages have exactly this feature:

• /* clang-format off */ in https://clang.llvm.org/docs/ClangFormatStyleOptions.html#disabling-formatting-on-a-piece-of-code
• #[rustfmt_skip] in https://github.com/rust-lang-nursery/rustfmt#tips
• // format: off in http://scalameta.org/scalafmt/#//format:off
• // @formatter:off in IntelliJ
• …

It feels necessary as a “safety valve”.
