Enhancements

• f6f42bb075cf186cdc19e3b55469a0c6c95f7257 allows the xmlns attribute on <template> elements in order to define custom elements which are a part of SVG/MathML.

Breaking changes

• c83140fea45537fc16beb50a2bb210afd4ce4911 dropped the support of Node.js 4.x.
• 4e2cd771dcf011b040eeccf7a748f40aba001201 dropped the support of ESLint 3.x and 4.x. And it upgraded espree and eslint-scope packages, vue-eslint-parser is using internally, to 4.0.0. This means it dropped the support of parserOptions.ecmaFeatures.experimentalObjectRestSpread option. Use ecmaVersion option instead.
• 87efc6d22d03a3e56c0e8097b33d826b69a35e29 added the support of slot-scope attribute to define variables which are available on inside of the element. The slot-scope attribute is expressed as new VSlotScopeExpression node. And it changed the AST of <template scope> attribute to the VSlotScopeExpression node.

Bug fixes

• f115c263200479f617de7c311712972c33173a58 fixed to allow empty directive values.

Bug fixes

• 812fd21a596e590eeade692298292e4b3ce950b0 fixed a bug that context.parserServices.defineTemplateBodyVisitor() doesn’t work if AST object was reused.

vue-eslint-parser has been rewritten completely!

Now vue-eslint-parser gets the ability to parse <template> (only HTML) in .vue files to AST.

• New parserServices:
  • defineTemplateBodyVisitor(templateVisitor, scriptVisitor) … returns ESLint visitor to traverse <template>.
  • getTemplateBodyTokenStore() … returns ESLint TokenStore to get the tokens of <template>.
• ast.md is <template> AST specification.
• mustache-interpolation-spacing.js is an example.

This is experimental version.

Features

• vue-eslint-parser parses <template> of single file components.
  • Plugin rules can traverse the AST of <template>.
  • Plugin rules can get tokens of the AST to check styles.
  • Plugin rules can get external references in expressions of directives to check typo or something like.

No change. It gets stable.

Breaking changes

• 5766096687a0b1420b1f0780d1970c13e9044351 changed the minimum ESLint version vue-eslint-parser supports. It requires 3.9.0 or later.
  The reason is that vue-eslint-parser needs parserServices feature to release the capabilities to access ASTs of <template> in future.

If no problem, I will release 1.0.0 with this version after a few day.

Bug fixes

• fba86130e1f82d3d0b63abddb192d102589b1e36 removed postinstall script which has caused an installation problem.

Features

• b16a6c1402276631b286b8e4d8e5ac2a199d3563 added the feature to use custom parsers to parse the inside of <script> tags (#1).
  See also README.md#options.

Docs

• 5f7f5fcc01502c22ee492c42cc478c1e17181d54 added the notation about the rules which are working incorrectly to “known limitations” section.
  See also README.md#known-limitations.

Chore

• https://github.com/mysticatea/vue-eslint-parser/compare/b16a6c1402276631b286b8e4d8e5ac2a199d3563...fd92c13bc9440ab8035f25171a64467755e6fb2f added tests more than 10000 cases. It runs the tests of ESLint core rules as making a use of this custom parser.
