Functions ¶
func ComputePositionOfLineAndByteOffset ¶
ComputePositionOfLineAndByteOffset computes a byte position from a line and raw byte offset from the line start. This is a simple addition with validation.
func ComputePositionOfLineAndUTF16Character ¶
func ComputePositionOfLineAndUTF16Character(lineStarts []core.TextPos, line int, character core.UTF16Offset, text string, allowEdits bool) int
ComputePositionOfLineAndUTF16Character converts a line and UTF-16 character offset back to a byte position. The character parameter is measured in UTF-16 code units. It scans from the line start to correctly handle multi-byte characters. When allowEdits is true, out-of-range values are clamped instead of panicking.
func DeclarationNameToString ¶
func GetECMAEndLinePosition ¶
func GetECMAEndLinePosition(sourceFile *ast.SourceFile, line int) int
func GetECMALineAndByteOffsetOfPosition ¶
func GetECMALineAndByteOffsetOfPosition(sourceFile ast.SourceFileLike, pos int) (line int, byteOffset int)
GetECMALineAndByteOffsetOfPosition returns the 0-based line number and the raw UTF-8 byte offset from the start of that line for the given byte position. Uses ECMAScript line separators (LF, CR, CRLF, LS, PS). Unlike GetECMALineAndUTF16CharacterOfPosition, the offset is in bytes, not UTF-16 code units.
func GetECMALineAndUTF16CharacterOfPosition ¶
func GetECMALineAndUTF16CharacterOfPosition(sourceFile ast.SourceFileLike, pos int) (line int, character core.UTF16Offset)
GetECMALineAndUTF16CharacterOfPosition returns the 0-based line number and the UTF-16 code unit offset from the start of that line for the given byte position. Uses ECMAScript line separators (LF, CR, CRLF, LS, PS).
func GetECMALineOfPosition ¶
func GetECMALineOfPosition(sourceFile ast.SourceFileLike, pos int) int
func GetECMALineStarts ¶
func GetECMALineStarts(sourceFile ast.SourceFileLike) []core.TextPos
func GetECMAPositionOfLineAndByteOffset ¶
func GetECMAPositionOfLineAndByteOffset(sourceFile ast.SourceFileLike, line int, byteOffset int) int
GetECMAPositionOfLineAndByteOffset converts a 0-based line number and byte offset from line start back to an absolute byte position in the source text. Uses ECMAScript line separators.
func GetECMAPositionOfLineAndUTF16Character ¶
func GetECMAPositionOfLineAndUTF16Character(sourceFile ast.SourceFileLike, line int, character core.UTF16Offset) int
GetECMAPositionOfLineAndUTF16Character converts a 0-based line number and UTF-16 code unit character offset back to an absolute byte position in the source text. Uses ECMAScript line separators.
