Working with Rules
Before you start writing a new rule, please read the official ESLint guide.
Next, in order to get an idea how does the AST of the code that you want to check looks like, use the astexplorer.net.The astexplorer.net is a great tool to inspect ASTs, also Vue templates are supported.
After opening astexplorer.net, select Vue as the syntax and vue-eslint-parser as the parser.
Since single file components in Vue are not plain JavaScript, the default parser couldn't be used, so a new one was introduced. vue-eslint-parser generates enhanced AST with nodes that represent specific parts of the template syntax, as well as what's inside the <script> tag.
To know more about certain nodes in produced ASTs, go here:
The vue-eslint-parser provides a few useful parser services that help traverse the produced AST and access tokens of the template:
context.parserServices.defineTemplateBodyVisitor(visitor, scriptVisitor)context.parserServices.getTemplateBodyTokenStore()
Check out an example rule to get a better understanding of how these work.
Please be aware that regarding what kind of code examples you'll write in tests, you'll have to accordingly set up the parser in RuleTester (you can do it on a per test case basis). See an example here.
If you'll stuck, remember there are plenty of rules you can learn from already. If you can't find the right solution, don't hesitate to reach out in issues – we're happy to help!

今天使用 Vue CLI 创建 Vue 应用，然后从之前的项目中拷贝 ESLint rules，但是 vscode 并没有识别，格式化配置中也没有 ESLint 选项。 一般这种情况应该是 ESLint 配置有问题，可能是插件、解析器或者规则。 一个一个注释后重载 vscode 查看效果，最终定位到 eslint-plugin-vue 下的 vue/max-attributes-per-line
