source_span 1.0.0

A library for identifying source spans and locations.

1.0.0

This package was extracted from the source_maps package, but the API has many differences. Among them:

• Span has been renamed to SourceSpan and Location has been renamed to SourceLocation to clarify their purpose and maintain consistency with the package name. Likewise, SpanException is now SourceSpanException and SpanFormatException is not SourceSpanFormatException.

• FixedSpan and FixedLocation have been rolled into the Span and Location classes, respectively.

• SourceFile is more aggressive about validating its arguments. Out-of-bounds lines, columns, and offsets will now throw errors rather than be silently clamped.

• SourceSpan.sourceUrl, SourceLocation.sourceUrl, and SourceFile.url now return Uri objects rather than Strings. The constructors allow either Strings or Uris.

• Span.getLocationMessage and SourceFile.getLocationMessage are now SourceSpan.message and SourceFile.message, respectively. Rather than taking both a useColor and a color parameter, they now take a single color parameter that controls both whether and which color is used.

• Span.isIdentifier has been removed. This property doesn't make sense outside of a source map context.

• SourceFileSegment has been removed. This class wasn't widely used and was inconsistent in its choice of which parameters were considered relative and which absolute.
