v5.4.1

Compare Source

v5.4.0

Compare Source

Added

• Added the scalarStyleRules dumper option to customize string formatting.
  See Scalar styling for details.

Changed

• [breaking] Flattened the low-level AST node style representation. Scalar
  and collection nodes now use SCALAR_STYLE and COLLECTION_STYLE values;
  explicit tags use the separate tagged property. Alias nodes now contain
  only kind and anchor. This only affects code that directly constructs or
  edits AST nodes.
• [breaking] The sortKeys option was rewritten using AST mutation to avoid
  side effects.
• Reworked scalar style selection. This can change formatting without changing
  loaded values; in particular, whitespace-only strings are now double-quoted.

Fixed

• Accept a byte order mark at the start of each document in a stream, #​791.
• Produce valid flow mappings with quoteFlowKeys and flowSkipColonSpace,
  including alias and property-only keys, #​786.
• Preserve empty scalar items when converting block sequences to flow style.
• Do not apply the 1024-character simple-key limit to flow mapping keys.
• Count Unicode code points, rather than UTF-16 code units, for the
  1024-character simple-key limit.
• Add an explicit document-end marker after keep-chomped block scalars when
  needed to preserve trailing newlines.

v5.3.0

Compare Source

This release focuses on reworking the documentation and making small
architectural improvements before moving forward.

Added

• Added completely new documentation.
• Exported DUMP_SCHEMA, the default schema used by the dumper.
• Added YAMLException.throwAt() for throwing an error at a source position.

Changed

• Changed flat constant exports to grouped exports: EVENT_ID, SCALAR_STYLE,
  COLLECTION_STYLE, and CHOMPING_MODE, along with their value types. The old
  exports are still preserved, but deprecated.
• Made identify mandatory for custom tag definitions. Use
  identify: () => false for load-only tags.

Deprecated

• Deprecated flat constant exports. Use grouped ones instead.

Removed

• Removed the MERGE_KEY export (not used anymore after last fixes).

Fixed

• Validate << sequence items at merge time, so aliased merge sources are
  checked too.
• Resolve << outside of a mapping key as the plain string '<<', matching
  v4, instead of leaking an internal symbol into the result.

v5.2.3

Compare Source

Fixed

• Prevent prototype fallback when resolving tags and mapping entries, #​782.
• Resolve !!timestamp years 0000-0099 correctly, #​775.
• Preserve implicit null mapping values before document markers and reject
  unpaired mapping event streams, #​784.
• Preserve folded scalar values with tab-indented lines when round-tripping a
  parsed AST through present(); dump() and loading are unaffected, #​780.
