Release Notes

nodeca/js-yaml (js-yaml)

v5.0.0

Compare Source

Added
  • Added named exports for schemas, tags, parser events and AST utilities.
  • Reworked JSON_SCHEMA and CORE_SCHEMA with spec-compliant scalar resolution
    rules, and added YAML11_SCHEMA.
  • Added realMapTag for lossless mappings with non-string and complex keys.
    Object-based mappings now reject complex keys instead of stringifying them.
  • Added dump() transform option for changing the generated AST before
    rendering.
  • Added dump() options seqInlineFirst, flowBracketPadding,
    flowSkipCommaSpace, flowSkipColonSpace, quoteFlowKeys, quoteStyle and
    tagBeforeAnchor.
  • Added formal data layers (events and AST) for modular data pipelines.
    • Added low-level parser (to events), presenter and visitor APIs.
  • Added the YAML Test Suite to the
    test set.
Changed
  • See the migration guide for upgrade notes.
  • Rewritten in TypeScript and reorganized the public API around flat named
    exports.
  • Reduced the set of exported schemas:
    • YAML 1.2 schemas: CORE_SCHEMA (loader default), JSON_SCHEMA,
      FAILSAFE_SCHEMA.
    • YAML11_SCHEMA, a combination of all YAML 1.1 tags (YAML 1.1 does not
      specify a schema, only "types").
  • load/dump default behaviour is now specified exactly via schemas:
    • load uses CORE_SCHEMA, without !!merge by default.
    • dump uses YAML11_SCHEMA + CORE_SCHEMA for the quoting check, to
      guarantee backward compatibility by default.
  • !!set is now loaded as a JavaScript Set.
  • Replaced the Type API with a tags API. Similar, but more precise and
    simpler. See examples for details. Tags can be defined via
    defineScalarTag(), defineSequenceTag() and defineMappingTag(), or as a
    spread + override of an existing tag.
  • Renamed Schema.extend() to Schema.withTags().
  • Expanded YAML 1.2 conformance and improved handling of directives, document
    markers, block keys, multiline scalars, tag syntax and other things.
  • load() now throws on empty input instead of returning undefined.
  • Moved browser builds to the js-yaml/browser export.
  • Deprecated the loadAll signature with an iterator (still works, but is a
    candidate for removal).
Removed
  • Removed deprecated safeLoad(), safeLoadAll() and safeDump() exports.
  • Removed DEFAULT_SCHEMA and the nested types export.
  • Removed loader options onWarning, legacy and listener.
  • Removed dumper options styles, replacer, noCompatMode, condenseFlow,
    quotingType and forceQuotes. Renamed noArrayIndent to seqNoIndent.
    Formatting and representation are now configured through presenter options,
    schemas and tag definitions. See migration guide on how to replace.
  • Removed support for importing internal files from lib/.

v4.2.0

Compare Source

Added
  • Added docs/safety.md with notes about processing untrusted YAML.
  • Added maxDepth (100) loader option. Not a problem, but gives a better
    exception instead of RangeError on stack overflow.
  • Added maxMergeSeqLength (20) loader option. Not a problem after merge fix,
    but an additional restriction for safety.
  • Added sourcemaps to dist/ builds.
Changed
  • Stop resolving numbers with underscores as numeric scalars, #​627.
  • Switched dev toolchains to Vite / neostandard.
  • Updated demo.
  • Reorganized tests.
  • dist/ files are no longer kept in the repository.
Fixed
  • Fix parsing of properties on the first implicit block mapping key, #​62.
  • Fix trailing whitespace handling when folding flow scalar lines, #​307.
  • Reject top-level block scalars without content indentation, #​280.
  • Ensure numbers survive round-trip, #​737.
  • Fix test coverage for issue #​221.
  • Fix flow scalar trailing whitespace folding, #​307.
  • Fix digits in YAML named tag handles.
Security
  • Fix potential DoS via quadratic complexity in merge - deduplicate repeated
    elements (makes sense for malformed files > 10K).

v4.1.1

Compare Source

Security
  • Fix prototype pollution issue in yaml merge (<<) operator.

v4.1.0

Compare Source

Added
  • Types are now exported as yaml.types.XXX.
  • Every type now has options property with original arguments kept as they were
    (see yaml.types.int.options as an example).
Changed
  • Schema.extend() now keeps old type order in case of conflicts
    (e.g. Schema.extend([ a, b, c ]).extend([ b, a, d ]) is now ordered as abcd instead of cbad).

v4.0.0

Compare Source

Changed
  • Check migration guide in docs for details of all breaking changes.
  • Breaking: "unsafe" tags !!js/function, !!js/regexp, !!js/undefined are
    moved to js-yaml-js-types package.
  • Breaking: removed safe* functions. Use load, loadAll, dump
    instead which are all now safe by default.
  • yaml.DEFAULT_SAFE_SCHEMA and yaml.DEFAULT_FULL_SCHEMA are removed, use
    yaml.DEFAULT_SCHEMA instead.
  • yaml.Schema.create(schema, tags) is removed, use schema.extend(tags) instead.
  • !!binary now always mapped to Uint8Array on load.
  • Reduced nesting of /lib folder.
  • Parse numbers according to YAML 1.2 instead of YAML 1.1 (01234 is now decimal,
    0o1234 is octal, 1:23 is parsed as string instead of base60).
  • dump() no longer quotes :, [, ], (, ) except when necessary, #​470, #​557.
  • Line and column in exceptions are now formatted as (X:Y) instead of
    at line X, column Y (also present in compact format), #​332.
  • Code snippet created in exceptions now contains multiple lines with line numbers.
  • dump() now serializes undefined as null in collections and removes keys with
    undefined in mappings, #​571.
  • dump() with skipInvalid=true now serializes invalid items in collections as null.
  • Custom tags starting with ! are now dumped as !tag instead of !<!tag>, #​576.
  • Custom tags starting with tag:yaml.org,2002: are now shorthanded using !!, #​258.
Added
  • Added .mjs (es modules) support.
  • Added quotingType and forceQuotes options for dumper to configure
    string literal style, #​290, #​529.
  • Added styles: { '!!null': 'empty' } option for dumper
    (serializes { foo: null } as "foo: "), #​570.
  • Added replacer option (similar to option in JSON.stringify), #​339.
  • Custom Tag can now handle all tags or multiple tags with the same prefix, #​385.
Fixed
  • Astral characters are no longer encoded by dump(), #​587.
  • "duplicate mapping key" exception now points at the correct column, #​452.
  • Extra commas in flow collections (e.g. [foo,,bar]) now throw an exception
    instead of producing null, #​321.
  • __proto__ key no longer overrides object prototype, #​164.
  • Removed bower.json.
  • Tags are now url-decoded in load() and url-encoded in dump()
    (previously usage of custom non-ascii tags may have led to invalid YAML that can't be parsed).
  • Anchors now work correctly with empty nodes, #​301.
  • Fix incorrect parsing of invalid block mapping syntax, #​418.
  • Throw an error if block sequence/mapping indent contains a tab, #​80.
