Synopsis

Core Types

type Anns = Map AnnKey Annotation Source #

This structure holds a complete set of annotations for an AST

data Annotation Source #

Constructors

Ann 

Fields

  • annEntryDelta :: !DeltaPos

    Offset used to get to the start of the SrcSpan, from whatever the prior output was, including all annPriorComments (field below).

  • annPriorComments :: ![(Comment, DeltaPos)]

    Comments coming after the last non-comment output of the preceding element but before the SrcSpan being annotated by this Annotation. If these are changed then annEntryDelta (field above) must also change to match.

  • annFollowingComments :: ![(Comment, DeltaPos)]

    Comments coming after the last output for the element subject to this Annotation. These will only be added by AST transformations, and care must be taken not to disturb layout of following elements.

  • annsDP :: ![(KeywordId, DeltaPos)]

    Annotations associated with this element.

  • annSortKey :: !(Maybe [SrcSpan])

    Captures the sort order of sub elements. This is needed when the sub-elements have been split (as in a HsLocalBind which holds separate binds and sigs) or for infix patterns where the order has been re-arranged. It is captured explicitly so that after the Delta phase a SrcSpan is used purely as an index into the annotations, allowing transformations of the AST including the introduction of new Located items or re-arranging existing ones.

  • annCapturedSpan :: !(Maybe AnnKey)

    Occasionally we must calculate a SrcSpan for an unlocated list of elements which we must remember for the Print phase. e.g. the statements in a HsLet or HsDo. These must be managed as a group because they all need eo be vertically aligned for the Haskell layout rules, and this guarantees this property in the presence of AST edits.
