new StringScanner()
now takes an optional sourceUrl
argument that provides the URL of the source file. This is used for error reporting.
Add StringScanner.readChar()
and StringScanner.peekChar()
methods for doing character-by-character scanning.
Scanners now throw StringScannerException
s which provide more detailed access to information about the errors that were thrown and can provide terminal-colored messages.
Add a LineScanner
subclass of StringScanner
that automatically tracks line and column information of the text being scanned.
Add a SpanScanner
subclass of LineScanner
that exposes matched ranges as [source map][] Span
objects.
