Ormolu.Printer.SpanStream

Description

Build span stream from AST.

Synopsis

- newtype SpanStream = SpanStream [RealSrcSpan]
- mkSpanStream :: Data a => a -> SpanStream

# Documentation

newtype SpanStream #

A stream of `RealSrcSpan`s in ascending order. This allows us to tell e.g. whether there is another "located" element of AST between current element and comment we're considering for printing.

Constructors

SpanStream [RealSrcSpan] |
