source_span 1.3.1

A library for identifying source spans and locations.

1.3.1

• Properly highlight spans for lines that include tabs with SourceSpan.highlight() and SourceSpan.message().

1.3.0

• Add SourceSpan.highlight(), which returns just the highlighted text that would be included in SourceSpan.message().

1.2.4

• Fix a new strong mode error.

1.2.3

• Fix a bug where a point span at the end of a file without a trailing newline would be printed incorrectly.

1.2.2

• Allow SourceSpanException.message, SourceSpanFormatException.source, and SourceSpanWithContext.context to be overridden in strong mode.

1.2.1

• Fix the declared type of FileSpan.start and FileSpan.end. In 1.2.0 these were mistakenly changed from FileLocation to SourceLocation.

1.2.0

• Deprecated: Extending SourceLocation directly is deprecated. Instead, extend the new SourceLocationBase class or mix in the new SourceLocationMixin mixin.

• Dramatically improve the performance of FileLocation.

1.1.6

• Optimize getLine() in SourceFile when repeatedly called.

1.1.5

• Fixed another case in which FileSpan.union could throw an exception for external implementations of FileSpan.

1.1.4

• Eliminated dart2js warning about overriding ==, but not hashCode.

1.1.3

• FileSpan.compareTo, FileSpan.==, FileSpan.union, and FileSpan.expand no longer throw exceptions for external implementations of FileSpan.

• FileSpan.hashCode now fully agrees with FileSpan.==.

1.1.2

• Fixed validation in SourceSpanWithContext to allow multiple occurrences of text within context.

1.1.1

• Fixed FileSpan's context to include the full span text, not just the first line of it.

1.1.0

• Added SourceSpanWithContext: a span that also includes the full line of text that contains the span.

1.0.3

• Cleanup equality operator to accept any Object rather than just a SourceLocation.

1.0.2

• Avoid unintentionally allocating extra objects for internal FileSpan operations.

• Ensure that SourceSpan.operator== works on arbitrary Objects.

1.0.1

• Use a more compact internal representation for FileSpan.

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.
