🐛 Bug fixes

• 7a1bffda55ea727d002cf2c2bbdb6800bc9a644f fixed the wrong location of auto-generated .prop modifiers.

This release supported the new syntax in Vue.js 2.6 🎉

• The shorthand of v-bind directive with .prop modifier. (actually, this is experimental and behind flag in Vue.js 2.6)
• New v-slot directive and that shorthand. (https://vuejs.org/v2/api/#v-slot)
• New dynamic arguments. (https://vuejs.org/v2/guide/syntax.html#Dynamic-Arguments)

Breaking changes

This release contains a drastic change about VDirectiveKey AST node because now the directive key have gotten to be able to have JavaScript expression.

  export interface VDirectiveKey extends HasLocation, HasParent {
      type: "VDirectiveKey"
      parent: VAttribute
-     name: string
-     argument: string | null
-     modifiers: string[]
-     shorthand: boolean
+     name: VIdentifier
+     argument: VExpressionContainer | VIdentifier | null
+     modifiers: VIdentifier[]
  }

• It changed the members name, argument, and modifiers to AST nodes from strings. Especially, argument will be a VExpressionContainer node if the directive has dynamic argument syntax.
• It removed shorthand member. To check wheather the directive key is a shorthand or not, use name.rawName member.
  • :foo ... directiveKey.name.rawName is ":" (and directiveKey.name.name is "bind").
  • .foo ... directiveKey.name.rawName is "." (and directiveKey.name.name is "bind" and directiveKey.modifiers includes the identifier node of "prop").
  • @foo ... directiveKey.name.rawName is "@" (and directiveKey.name.name is "on").
  • #foo ... directiveKey.name.rawName is "#" (and directiveKey.name.name is "slot").

✨ Enhancements

• 04bf33b7f8a282534cc572f02f31812ea5a51fb7 made the parser throwing syntax errors on illegal slot-scope attributes.

Chore

• 40452394cd81da0503f7ed8bdeba76e364675888 separated a dynamic require() expression to two in order to make Webpack recognizable that it's depending on espree.

Bug fixes

• c0e91901be6b2fa8ba1de79174f0b06033eaf87e made the parser throwing syntax error on the top-level commas in v-bind directives (E.g., :foo="a,b"). It was parsed to SequenceExpression wrongly before.

Enhancements

• 9b947b11fac73ac5baac1fee35c19b47afb21f1c added the option parserOptions.parser:false to skip parsing <script> elements completely. This is useful for the language ESLint community don't provide that custom parser.

Bug fixes

• 7de2b86dcb5740861a94b3c3b9a5e777f8ee7b28 fixed the list of void element names to be acording to WHATWG spec.
• adbaf4b7a4651d0b3c7627e9aba74adf9c7c3d8c fixed the list of normal element names to be acording to WHATWG spec.

• 6906fb16d099fe6c04a6f3adb1b48ac46a241e9c fixed the parser to allow empty mustaches.

Bug fixes

• fa73293541c1b3f0113438fa5765ecf407cffa20 fixed the bug that vue-eslint-parser parsed the v-on directive with no argument and an object expression (e.g., v-on="{foo: bar}") to a block statement. (#30)

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.
