A parse tree is a graphical representation of the derivation process of an input program, showing each grammar symbol used in the derivation. It can be simplified by abstracting unnecessary nodes, leading to an abstract syntax tree commonly used in compiler design. ...

所以我们从的转换过程,就是从一串String的模版到virtuedomtree的过程。 但是值得一提的是,vue从模版到vdom的过程并非是直接一次性到位的过程。可能是因为尤大的设计的vnode和原生的dom属性差距过大,直接编译成vnode不好完成。其次是考虑到性能优化等方面。 所以vue的编译过程其实是分为三个过程: parse optimize codege...
AST 的全称是 Abstract Syntax Tree(抽象语法树),是源代码的抽象语法结构的树状表现形式,计算机学科中编译原理的概念。Vue 源码中借鉴 jQuery 作者 John Resig 的 HTML Parser 对模板进行解析,得到的就是 AST 代码。 接着我们看一下Vue中对AST数据的定义: ...
function closeElement (element) { trimEndingWhitespace(element) // 去除 未部对空格元素 if (!inVPre && !element.processed) { element = processElement(element, options) // 处理Vue相关对一些属性关系 } // tree management if (!stack.length && element !== root) { // allow root elements with...
); } } } // tree management if (!root) { root = element; checkRootConstraints(root); } else if (!stack.length) { // allow root elements with v-if, v-else-if and v-else if (root.if && (element.elseif || element.else)) { checkRootConstraints(element); addIfCondition(root, ...
Parse trees arean in-memory representation of the input with a structure that conforms to the grammar. The advantages of using parse trees instead of semantic actions: You can make multiple passes over the data without having to re-parse the input. You can perform transformations on the tree....
