Description

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

Constructing SrcLoc

mkGeneralSrcLoc :: FastString -> SrcLoc Source #

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

noSrcLoc :: SrcLoc Source #

Built-in "bad" SrcLoc values for particular locations

generatedSrcLoc :: SrcLoc Source #

Built-in "bad" SrcLoc values for particular locations

interactiveSrcLoc :: SrcLoc Source #

Built-in "bad" SrcLoc values for particular locations

advanceSrcLoc :: RealSrcLoc -> Char -> RealSrcLoc Source #

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 Source #

Gives the filename of the RealSrcLoc

srcLocLine :: RealSrcLoc -> Int Source #

Raises an error when used on a "bad" SrcLoc

srcLocCol :: RealSrcLoc -> Int Source #

Raises an error when used on a "bad" SrcLoc

SrcSpan

data RealSrcSpan Source #

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.

mkSrcSpan :: SrcLoc -> SrcLoc -> SrcSpan Source #

Create a SrcSpan between two points in a file

mkRealSrcSpan :: RealSrcLoc -> RealSrcLoc -> RealSrcSpan Source #

Create a SrcSpan between two points in a file

srcLocSpan :: SrcLoc -> SrcSpan Source #

Create a SrcSpan corresponding to a single point

combineSrcSpans :: SrcSpan -> SrcSpan -> SrcSpan Source #

Combines two SrcSpan into one that spans at least all the characters within both spans. Returns UnhelpfulSpan if the files differ.

srcSpanFirstCharacter :: SrcSpan -> SrcSpan Source #

Convert a SrcSpan into one that represents only its first character

Deconstructing SrcSpan

srcSpanStart :: SrcSpan -> SrcLoc Source #

Returns the location at the start of the SrcSpan or a "bad" SrcSpan if that is unavailable

Predicates on SrcSpan

isGoodSrcSpan :: SrcSpan -> Bool Source #

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

isOneLineSpan :: SrcSpan -> Bool Source #

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

containsSpan :: RealSrcSpan -> RealSrcSpan -> Bool Source #

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

type family SrcSpanLess a Source #

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.
