yaml 3.1.0

A parser for YAML, a human-friendly data serialization standard

3.1.0

• loadYaml and related functions now accept a recover flag instructing the parser to attempt to recover from parse errors and may return invalid or synthetic nodes. When recovering, an ErrorListener can also be supplied to listen for errors that are recovered from.
• Drop dependency on package:charcode.

3.0.0

• Stable null safety release.

3.0.0-nullsafety.0

• Updated to support 2.12.0 and null safety.
• Allow YamlNodes to be wrapped with an optional style parameter.
• BREAKING The sourceUrl named argument is statically typed as Uri instead of allowing String or Uri.

2.2.1

• Update min Dart SDK to 2.4.0.
• Fixed span for null nodes in block lists.

2.2.0

• POSSIBLY BREAKING CHANGE: Make YamlMap preserve parsed key order. This is breaking because some programs may rely on the HashMap sort order.

2.1.16

• Fixed deprecated API usage in README.
• Fixed lints that affect package score.

2.1.15

• Set max SDK version to <3.0.0, and adjust other dependencies.

2.1.14

• Remove use of deprecated features.
• Updated SDK version to 2.0.0-dev.17.0

2.1.13

• Stop using comment-based generic syntax.

2.1.12

• Properly refuse mappings with duplicate keys.

2.1.11

• Fix an infinite loop when parsing some invalid documents.

2.1.10

• Support string_scanner 1.0.0.

2.1.9

• Fix all strong-mode warnings.

2.1.8

• Remove the dependency on path, since we don't actually import it.

2.1.7

• Fix more strong mode warnings.

2.1.6

• Fix two analysis issues with DDC's strong mode.

2.1.5

• Fix a bug with 2.1.4 where source span information was being discarded for scalar values.

2.1.4

• Substantially improve performance.

2.1.3

• Add a hint that a colon might be missing when a mapping value is found in the wrong context.

2.1.2

• Fix a crashing bug when parsing block scalars.

2.1.1

• Properly scope SourceSpans for scalar values surrounded by whitespace.

2.1.0

• Rewrite the parser for a 10x speed improvement.

• Support anchors and aliases (&foo and *foo).

• Support explicit tags (e.g. !!str). Note that user-defined tags are still not fully supported.

• %YAML and %TAG directives are now parsed, although again user-defined tags are not fully supported.

• YamlScalar, YamlList, and YamlMap now expose the styles in which they were written (for example plain vs folded, block vs flow).

• A yamlWarningCallback field is exposed. This field can be used to customize how YAML warnings are displayed.

2.0.1+1

• Fix an import in a test.

• Widen the version constraint on the collection package.

2.0.1

• Fix a few lingering references to the old Span class in documentation and tests.

2.0.0

• Switch from source_maps' Span class to source_span's SourceSpan class.

• For consistency with source_span and string_scanner, all sourceName parameters have been renamed to sourceUrl. They now accept Urls as well as Strings.

1.1.1

• Fix broken type arguments that caused breakage on dart2js.

• Fix an analyzer warning in yaml_node_wrapper.dart.

1.1.0

• Add new publicly-accessible constructors for YamlNode subclasses. These constructors make it possible to use the same API to access non-YAML data as YAML data.

• Make YamlException inherit from source_map's SpanFormatException. This improves the error formatting and allows callers access to source range information.

1.0.0+1

• Fix a variable name typo.

1.0.0

• Backwards incompatibility: The data structures returned by loadYaml and loadYamlStream are now immutable.

• Backwards incompatibility: The interface of the YamlMap class has changed substantially in numerous ways. External users may no longer construct their own instances.

• Maps and lists returned by loadYaml and loadYamlStream now contain information about their source locations.

• A new loadYamlNode function returns the source location of top-level scalars as well.

0.10.0

• Improve error messages when a file fails to parse.

0.9.0+2

• Ensure that maps are order-independent when used as map keys.

0.9.0+1

• The YamlMap class is deprecated. In a future version, maps returned by loadYaml and loadYamlStream will be Dart HashMaps with a custom equality operation.
