LocationImpl

Implementation of location in source file, which can store different data based on compile time flags.

struct LocationImpl (

LocationTypeFlags flags

T = int

) {

static if(flags & LocationTypeFlags.bytes)

static if(flags & LocationTypeFlags.lines)

static if(flags & LocationTypeFlags.lineOffset)

this(AliasSeqIf!((flags & LocationTypeFlags.bytes) != 0, T) bytePos, AliasSeqIf!((flags & LocationTypeFlags.lines) != 0, T) line, AliasSeqIf!((flags & LocationTypeFlags.lineOffset) != 0, T) offset);

alias LocationAbs = LocationImpl!(flags & ~LocationTypeFlags.diff, T);

alias LocationDiff = LocationImpl!(flags | LocationTypeFlags.diff, T);

bool isValid();

LocationDiff opBinary(LocationImpl rhs);

LocationImpl opBinary(LocationDiff rhs);

LocationImpl opBinary(LocationDiff rhs);

int opCmp(LocationImpl rhs);

void advance(string str);

static LocationImpl fromStr(string str);

string toString();

string toPrettyString();

}

Constructors

this this(AliasSeqIf!((flags & LocationTypeFlags.bytes) != 0, T) bytePos, AliasSeqIf!((flags & LocationTypeFlags.lines) != 0, T) line, AliasSeqIf!((flags & LocationTypeFlags.lineOffset) != 0, T) offset): Create location.

Members

Aliases

LocationAbs alias LocationAbs = LocationImpl!(flags & ~LocationTypeFlags.diff, T): Same type, but as absolute difference from beginning.
LocationDiff alias LocationDiff = LocationImpl!(flags | LocationTypeFlags.diff, T): Same type, but as difference between locations.

Functions

advance void advance(string str): Add location difference from string.
isValid bool isValid(): Check if the location is valid.
opBinary LocationDiff opBinary(LocationImpl rhs): Substract absolute locations.
opBinary LocationImpl opBinary(LocationDiff rhs): Substract difference from absolute location.
opBinary LocationImpl opBinary(LocationDiff rhs): Add difference to absolute location.
opCmp int opCmp(LocationImpl rhs): Compare locations.
toPrettyString string toPrettyString(): Represent location as string.
toString string toString(): Represent location as string.

Manifest constants

invalid enum invalid;: Special invalid value.
max enum max;: Maximum value.
zero enum zero;: Location for beginning of file or zero difference.

Static functions

fromStr LocationImpl fromStr(string str): Calculate location difference from string.

Variables

bytePos T bytePos;: Number of bytes.
line T line;: Number of lines
offset T offset;: Number of bytes since beginning of line.

Parameters

flags: Configuration of available fields.
T: Type used for numbers in the location.
