source_span 1.9.1 source_span: ^1.9.1 copied to clipboard
A library for identifying source spans and locations.
Properly handle multi-line labels for multi-span highlights.

- Fix a bug where highlighting multiple spans with
nullURLs could cause an assertion error. Now when multiple spans are passed with
nullURLs, they're highlighted as though they all come from different source files.
- Fix a bug where the URL header for the highlights with multiple files would get omitted only one span has a non-null URI.
- Stable release for null safety.
- Add a
SourceSpan.subspan()extension method which returns a slice of an existing source span.
- Add support for highlighting multiple source spans at once, providing more
context for span-based messages. This is exposed through the new APIs
SourceSpan.messageMultiple()(both extension methods),
- Fix padding around line numbers that are powers of 10 in
- Fix a bug where
FileSpan.highlight()would crash for spans that covered a trailing newline and a single additional empty line.
FileSpan.highlight()now properly highlights point spans at the beginning of lines.
- Fix an edge case where
FileSpan.highlight()would put the highlight indicator in the wrong position when highlighting a point span after the end of a file.
SourceFile.span()now goes to the end of the file by default, rather than ending one character before the end of the file. This matches the documented behavior.
FileSpan.contextnow includes the full line on which the span appears for empty spans at the beginning and end of lines.
Fix an edge case where
FileSpan.highlight()could crash when highlighting a span that ended with an empty line.
Produce better source span highlights for multi-line spans that cover the entire last line of the span, including the newline.
Produce better source span highlights for spans that contain Windows-style newlines.

<3.0.0, and adjust other dependencies.
new SourceFile()constructor is deprecated. This constructed a source file from a string's runes, rather than its code units, which runs counter to the way Dart handles strings otherwise. The
new StringFile.fromString()constructor (see below) should be used instead.
new SourceFile.fromString()constructor was added. This works like
new SourceFile(), except it uses code units rather than runes.

This package was extracted from the
source_maps package, but the
API has many differences. Among them:
Spanhas been renamed to
Locationhas been renamed to
SourceLocationto clarify their purpose and maintain consistency with the package name. Likewise,
FixedLocationhave been rolled into the
SourceFileis more aggressive about validating its arguments. Out-of-bounds lines, columns, and offsets will now throw errors rather than be silently clamped.
Uriobjects rather than
Strings. The constructors allow either
SourceFile.message, respectively. Rather than taking both a
colorparameter, they now take a single
colorparameter that controls both whether and which color is used.
Span.isIdentifierhas been removed. This property doesn't make sense outside of a source map context.
SourceFileSegmenthas been removed. This class wasn't widely used and was inconsistent in its choice of which parameters were considered relative and which absolute.
