Source.Span

Description

Source position and span information

Mostly taken from purescript's SourcePos definition.

Synopsis

data Span = Span {
- start :: !Pos
- end :: !Pos
}
point :: Pos -> Span
spanFromSrcLoc :: SrcLoc -> Span
data Pos = Pos {
- line :: !Int
- column :: !Int
}
line_ :: Lens' Pos Int
column_ :: Lens' Pos Int
class HasSpan a where
- span_ :: Lens' a Span
- start_ :: Lens' a Pos
- end_ :: Lens' a Pos
