[yozora][]: 一个基于中间件思想的、零外部依赖的 Markdown 解析器，用于将 Markdown 字符串转成 [Markdown AST][@yozora/ast]* [yozora-react][]: 一个基于 React 的 Markdown 渲染器，用于将 [Markdown AST][@yozora/ast] 渲染成 React 组件https://user-images.githubusercontent.com/42513619/129205123-6a1983c4-6a86-4c80-83d6-02bdbf70edbf.mp4## ✨ Features* 完整支持了 [GFM 规范][gfm-spec] 中提到的所有规则，并通过了几乎所有由规范中的示例改造成的测试用例（除了示例 https://github.github.com/gfm/#example-653，因为 [渲染器][yozora-react] 不打算支持原生的 HTML Tag，所以懒得做标签过滤，如果有需要自行做一下过滤就好了）。可参见 [@yozora/parser-gfm] or [@yozora/parser-gfm-ex] 以获得进一步信息。* 健壮性 - 所有代码都采用 Typescript 编写，拥有严格地静态类型检查的保障； - 使用 eslint 和 prettier 约束编码风格，规避了偏僻语法及 shadow variables 之类易于出错的问题； - 使用了大量的测试用例进行测试；* 干净，零第三方依赖。* 高性能 - 解析复杂度为字符串长度乘以分词器列表长度，已经达到了理论复杂度的下界； - 解析器的 API 支持流式读入（采用生成器/迭代器进行输入），支持边读入边解析（暂仅限于块级数据）； - 在读入字符串时，会将其预处理成字符编码及位置信息，使用 [NodePoint][src-NodePoint] 数据类型承载。在分词阶段通过扫描 [NodePoint][src-NodePoint] 的方式完成匹配，虽然匹配过程更麻烦些，但理论上性能比正则表达式的匹配方式少一些常数； - 小心地处理数组新建/连接操作，整个扫描阶段尽量复用数组，仅通过下标索引来圈定匹配范围，并应用了不少策略减少重复匹配/解析操作。 * 兼容性，解析器解析出的 AST 与 [Mdast][mdast-homepage] 中定义的相兼容。即便以后如果部分数据类型不兼容，也可以很容易通过 [@yozora/ast-util][] 中提供的 API 去遍历 AST 以进行适配修改。* 可扩展性，yozora 采用中间件的方式，由内部算法驱动分词器列表完成解析工作，因而易于创建并集成自定义的分词器。此项目中已实现了一些 [GFM][gfm-spec] 中未提到的数据类型的分词器，如 [@yozora/tokenizer-admonition][], [@yozora/tokenizer-footnote][] 等，且均已内置于 [@yozora/parser][] 中。[src-NodePoint]:
