yaml 2.0.0-11

on Node.js NPM

This version of yaml has been published to npm using the next dist-tag, so install it with:

npm install --save-exact yaml@next

BREAKING CHANGES

YAML.defaultOptions is removed (#346)

For a while, it's been undocumented, but still available. Since the options refactor of #235, it has only provided defaults for Parse & Document options, and not any of the others, so its name is a bit misleading as well.

If you're using YAML.defaultOptions, you'll need to explicitly set the options in the appropriate parse*() and new Document() calls after this change.

directives.marker is renamed as directives.docStart (#371)

The behaviour of the property stays the same as before.

New Features

• Add warning for aliases & anchors ending with a colon (#370)
• Add directives.docEnd, for ... marker (#371)
• Add YAML.visitAsync() (#372)

Bugfixes

• Flow collection keys in block maps (redhat-developer/vscode-yaml#712)
• Error on %YAML directives with content after version (#348)
• Use correct check for empty null source (#366)
• Do not throw during composition, even for bad tokens (#367)
• Error on invalid %YAML directives
• Empty block scalars with chomp=keep & trailing whitespace
• Parse ? : x as { ? { : x } }
• Do not consider tabs as indent for flow collections
• Include trailing more-indented empty lines in block scalar contents
• Should complain about -, and -] in flow collections
• Update dev dependencies, including @types/node downgrade

Test Improvements

• Update yaml-test-suite, skipping some new tests
• Don't needlessly skip yaml-test-suite B63P test
• test-events: Do not skip events for only apparently empty documents
• yaml-test-suite: Skip in.json tests when expecting errors
