Ormolu.Printer.SpanStream

Description

Build span stream from AST.

Synopsis

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

Documentation

newtype SpanStream Source #

A stream of RealSrcSpans 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]
