yaml 1.10.0

on Node.js NPM

This will probably be the last minor release of yaml@1. I'm aiming to release yaml@2 within a few months; prereleases of that will be published using the next dist-tag on npm. Patch releases for 1.10 may still happen, if necessary.

New Features

• Use Rollup for Node.js & browser builds (#165)
  • This removes most of the internal dist/ paths from the release. If you want/need to use a class or function that is no longer public, please file an issue and we can add it to the exports.
  • Drop dependency on @babel/runtime. After this, the package has 0 runtime dependencies. 🎉
  • Add exports { Alias, Collection, Merge, Node } to 'yaml/types'
• Document Schema.createPair() & make its ctx arg optional (#157)
• Always indent top-level scalars with lines starting with document markers or % directives (#162)
• Use double-space when forcing top-level block scalar indent, for clarity (#162)
• Add getNodes(): string[] method to Anchors (#166)
• Refactor Jest config, adding tests for compiled dist/ endpoints
• Rename & refactor source files. This should have no effect on the results, but lots of stuff moved around

Improved Errors & Warnings

• Throw more helpful error when setting Pair.commentBefore incorrectly (#157)
• Better errors for bad indents (#169)
• Drop incorrect error for flow mapping keys with length > 1024 chars
• Add errors for plain scalars that start with reserved indicators
• Add more explicit errors for block scalar values with bad indents
• Enable log prints during npm start debugging

Improved TypeScript declarations

• Fix/simplify export mapping of 'yaml/types' and 'yaml/util'
• Fix types, dropping AST.{AstNode,ScalarNode,CollectionNode} (#160)
• Add missing toString() methods to AST nodes (#159)
• Add directivesEndMarker to Document type (#167)

Bugfixes

• Use CommonJS for top-level default-exporting browser endpoints (#163)
• docs: Add note about simpleKeys for null values (#170)
• Update dev & playground dependencies, including eslint 7 & jest 26
• Update yaml-test-suite, fixing errors in remaining invalid-input tests
  • Add explicit error for block scalars with more-indented leading empty lines (S98Z)
  • Properly add error for tab-indented map values (4EJS)
  • Add error for multiline implicit flow sequence pair key (DK4H & ZXT5)
  • Require space after comma before comment in flow collections (CVW2)
  • Use mapAsMap: true for out.yaml tests (4FJ6)
