SrcLoc

This module contains types that relate to the positions of things in source files, and allow tagging of those things with locations

Constructing SrcLoc

mkSrcLoc :: FastString -> Int -> Int -> SrcLoc

mkRealSrcLoc :: FastString -> Int -> Int -> RealSrcLoc

mkGeneralSrcLoc :: FastString -> SrcLoc

Creates a "bad" SrcLoc that has no detailed information about its location

noSrcLoc :: SrcLoc

Built-in "bad" SrcLoc values for particular locations

generatedSrcLoc :: SrcLoc

Built-in "bad" SrcLoc values for particular locations

interactiveSrcLoc :: SrcLoc

Built-in "bad" SrcLoc values for particular locations

advanceSrcLoc :: RealSrcLoc -> Char -> RealSrcLoc

Move the SrcLoc down by one line if the character is a newline, to the next 8-char tabstop if it is a tab, and across by one character in any other case

Unsafely deconstructing SrcLoc

srcLocFile :: RealSrcLoc -> FastString

Gives the filename of the RealSrcLoc

srcLocLine :: RealSrcLoc -> Int

Raises an error when used on a "bad" SrcLoc

srcLocCol :: RealSrcLoc -> Int

Raises an error when used on a "bad" SrcLoc

SrcSpan

data RealSrcSpan

A RealSrcSpan delimits a portion of a text file. It could be represented by a pair of (line,column) coordinates, but in fact we optimise slightly by using more compact representations for single-line and zero-length spans, both of which are quite common.

The end position is defined to be the column after the end of the span. That is, a span of (1,1)-(1,2) is one character long, and a span of (1,1)-(1,1) is zero characters long.

isGoodSrcSpan :: SrcSpan -> Bool

Test if a SrcSpan is "good", i.e. has precise location information

True if the span is known to straddle only one line. For "bad" SrcSpan, it returns False

containsSpan :: RealSrcSpan -> RealSrcSpan -> Bool

Tests whether the first span "contains" the other span, meaning that it covers at least as much source code. True where spans are equal.

addCLoc :: (HasSrcSpan a, HasSrcSpan b, HasSrcSpan c) => a -> b -> SrcSpanLess c -> c

Combine locations from two Located things and add them to a third thing

spans :: SrcSpan -> (Int, Int) -> Bool

Determines whether a span encloses a given line and column index

isSubspanOf

Arguments

:: SrcSpan

The span that may be enclosed by the other

-> SrcSpan

The span it may be enclosed by

-> Bool

Determines whether a span is enclosed by another one

sortLocated :: HasSrcSpan a => [a] -> [a]

HasSrcSpan

class HasSrcSpan a where

A typeclass to set/get SrcSpans

Methods

composeSrcSpan :: Located (SrcSpanLess a) -> a

Composes a SrcSpan decoration with an undecorated syntactic entity to form its decorated variant

decomposeSrcSpan :: a -> Located (SrcSpanLess a)

Decomposes a decorated syntactic entity into its SrcSpan decoration and its undecorated variant

Instances

HasSrcSpan Name

Defined in Name

Methods

composeSrcSpan :: Located (SrcSpanLess Name) -> Name

decomposeSrcSpan :: Name -> Located (SrcSpanLess Name)

HasSrcSpan (Located a)

Defined in SrcLoc

Methods

composeSrcSpan :: Located (SrcSpanLess (Located a)) -> Located a

decomposeSrcSpan :: Located a -> Located (SrcSpanLess (Located a))

type family SrcSpanLess a

Determines the type of undecorated syntactic entities For most syntactic entities E, where source location spans are introduced by a wrapper construtor of the same syntactic entity, we have `SrcSpanLess E = E`. However, some syntactic entities have a different type compared to a syntactic entity `e :: E` may have the type `Located E` when decorated by wrapping it with `L sp e` for a source span sp.

Instances

type SrcSpanLess Name

Defined in Name

type SrcSpanLess Name = Name

type SrcSpanLess (GenLocated l e)

Defined in SrcLoc

type SrcSpanLess (GenLocated l e) = e

dL :: HasSrcSpan a => a -> Located (SrcSpanLess a)

An abbreviated form of decomposeSrcSpan, mainly to be used in ViewPatterns

cL :: HasSrcSpan a => SrcSpan -> SrcSpanLess a -> a

An abbreviated form of composeSrcSpan, mainly to replace the hardcoded L

pattern LL :: HasSrcSpan a => SrcSpan -> SrcSpanLess a -> a

A Pattern Synonym to Set/Get SrcSpans

onHasSrcSpan :: (HasSrcSpan a, HasSrcSpan b) => (SrcSpanLess a -> SrcSpanLess b) -> a -> b

Lifts a function of undecorated entities to one of decorated ones

liftL :: (HasSrcSpan a, HasSrcSpan b, Monad m) => (SrcSpanLess a -> m (SrcSpanLess b)) -> a -> m b
