自新世界 0x06:生活在 AST 上

rehype-remnote

写了一个可以从 RemNote 导出的 .rem 文件中生成 hast。hast 是 rehype 所用的抽象语法树,实际写下来感觉还是挺方便的。

.rem 文件结构

新的 .rem 文件本质是一个 .tar.gz 压缩包(以前则是 .zip),解压后有一个 rem.json 文件,里面包含了所有笔记的内容。应该是为了节省空间,所以这个 JSON 中很多字段的名称都很难以分辨。于是写了一个测试各种样式的页面,导出看效果,根据效果修改代码。

文件的结构大概是这样:

type 
type Workspace = {
    userId: string;
    knowledgebaseId: string;
    name: string;
    exportDate: string;
    exportVersion: number;
    documentRemToExportId: string;
    docs: Doc[];
}
Workspace
= {
userId: stringuserId: string; knowledgebaseId: stringknowledgebaseId: string; name: stringname: string; exportDate: stringexportDate: string; exportVersion: numberexportVersion: number; documentRemToExportId: stringdocumentRemToExportId: string; docs: Doc[]docs: type Doc = /*unresolved*/ anyDoc[]; }

整个 docs 的结构是扁平而有序的,通过 _id 来找到对应的内容。对于单个 Doc,主要的内容在 .key 中。.key 中存储的内容是 (string|object)[]。对于一张卡片,如果有涉及到闪卡的部分,可能会把背面的内容放在其他地方。

一些特殊的 block 类型会存储在几个特殊的 block 中,比如

type type RemTypes = "Daily Document" | "Document" | "Automatically Sort" | "Tags" | "Template Slot" | "Header" | "Website" | "Link" | "Quote" | "Image" | "Code" | "Card Item" | "List Item"RemTypes = "Daily Document"
| "Document"
| "Automatically Sort"
| "Tags"
| "Template Slot"
| "Header"
| "Website"
| "Link"
| "Quote"
| "Image"
| "Code"
| "Card Item"
| "List Item"

如何使用

可以参考 Rem.astro 文件。

  • 如果你只需要最后的 HTML,那么可以调用 rem2Html
  • 如果你需要将 rem.json 的内容提交到版本管理系统中,那么建议你先调用 hydrate 来生成一个精简的、树状的 JSON。
  • 如果你想要走完整个 unified 的 pipeline,得有一个 parser 来初始化 unist:
import { const unified: Processor<undefined, undefined, undefined, undefined, undefined>
Create a new processor.
@example This example shows how a new processor can be created (from `remark`) and linked to **stdin**(4) and **stdout**(4). ```js import process from 'node:process' import concatStream from 'concat-stream' import {remark} from 'remark' process.stdin.pipe( concatStream(function (buf) { process.stdout.write(String(remark().processSync(buf))) }) ) ```@returns New *unfrozen* processor (`processor`). This processor is configured to work the same as its ancestor. When the descendant processor is configured in the future it does not affect the ancestral processor.
unified
, type type Parser<Tree extends import("unist").Node = Node> = (document: string, file: VFile) => Tree
A **parser** handles the parsing of text to a syntax tree. It is used in the parse phase and is called with a `string` and {@linkcode VFile } of the document to parse. It must return the syntax tree representation of the given file ( {@linkcode Node } ).
Parser
} from "unified";
function function remParse(): voidremParse() { const const self: anyself = this; const self: anyself.parser = function (local function) parser(doc: string, file: unknown): anyparser as type Parser<Tree extends import("unist").Node = Node> = (document: string, file: VFile) => Tree

;
function function (local function) parser(doc: string, file: unknown): anyparser(doc: stringdoc: string, file: unknownfile: unknown) { return transformDoc(...); } } let let processor: anyprocessor = function unified(): Processor<undefined, undefined, undefined, undefined, undefined>

This processor is configured to work the same as its ancestor. When the descendant processor is configured in the future it does not affect the ancestral processor.
unified
().
Processor<undefined, undefined, undefined, undefined, undefined>.use<[], undefined, undefined>(plugin: Plugin<[], undefined, undefined>, ...parameters: [] | [boolean]): Processor<undefined, undefined, undefined, undefined, undefined> (+2 overloads)
Configure the processor to use a plugin, a list of usable values, or a preset. If the processor is already using a plugin, the previous plugin configuration is changed based on the options that are passed in. In other words, the plugin is not added a second time. > **Note**: `use` cannot be called on *frozen* processors. > Call the processor first to create a new unfrozen processor.
@example There are many ways to pass plugins to `.use()`. This example gives an overview: ```js import {unified} from 'unified' unified() // Plugin with options: .use(pluginA, {x: true, y: true}) // Passing the same plugin again merges configuration (to `{x: true, y: false, z: true}`): .use(pluginA, {y: false, z: true}) // Plugins: .use([pluginB, pluginC]) // Two plugins, the second with options: .use([pluginD, [pluginE, {}]]) // Preset with plugins and settings: .use({plugins: [pluginF, [pluginG, {}]], settings: {position: false}}) // Settings only: .use({settings: {position: false}}) ```@template{Array<unknown>} [Parameters=[]]@template{Node | string | undefined} [Input=undefined]@template[Output=Input]@overload@overload@overload@paramvalue Usable value.@paramparameters Parameters, when a plugin is given as a usable value.@returnsCurrent processor.

如何在服务端(Astro SSR/SSG, etc.)使 UnoCSS 对动态字符串生效

RemNote 中可以设置文字和背景的颜色,可以是预设的颜色,也可以是自定义的颜色。因此我对应生成了 Tailwind 的 class 名。

但是,原子化 CSS 框架 UnoCSS 作用的原理是使用正则表达式扫描源码来生成规则。为了防止最终的结果 diverge,所以不会扫描产出结果。这意味着在 Astro 中,即使是 SSG 模式下也无法处理 JS 动态生成的字符串。

const r = `<span class="text-red-600">红色</span>`;
const y = 'PHNwYW4gY2xhc3M9InRleHQteWVsbG93LTYwMCI+eWVsbG93PC9zcGFuPg==';
---
<div set:html={r} />
<div set:html={atob(y)} />
<div class="text-blue-600">蓝色</div>

(其中 atob(y) 的结果是 <span class="text-yellow-600">yellow</span>

渲染结果

黄色
蓝色

解决方案

unocss 提供了一个 createGenerator 方法,可以用来生成 CSS 字符串。

import { function createGenerator<Theme extends object = object>(config?: UserConfig<Theme>, defaults?: UserConfigDefaults<Theme>): UnoGenerator<Theme>createGenerator } from "unocss";
import import unoConfigunoConfig from "uno.config"; // 导入当前项目的 UnoCSS 配置
 
export async function function generateUno(content: string, layer?: string): Promise<string | undefined>
Generate UnoCSS style from HTML string
@paramcontent HTML string@returnsCSS string
generateUno
(content: string
HTML string
@paramcontent HTML string
content
: string, layer: stringlayer: string = 'default') {
const const generator: UnoGenerator<object>generator = createGenerator<object>(config?: UserConfig<object> | undefined, defaults?: UserConfigDefaults<object> | undefined): UnoGenerator<object>createGenerator(import unoConfigunoConfig); const const style: GenerateResult<Set<string>>style = await const generator: UnoGenerator<object>generator.UnoGenerator<object>.generate(input: string | Set<string> | CountableSet<string> | string[], options?: GenerateOptions<false>): Promise<GenerateResult<Set<string>>> (+1 overload)generate(content: string
HTML string
@paramcontent HTML string
content
);
// 返回的内容为不同 layer 的 CSS 字符串,这里我们只用到了 default layer return const style: GenerateResult<Set<string>>style.GenerateResult<Set<string>>.getLayer: (name?: string) => string | undefinedgetLayer(layer: stringlayer); }

接着,在使用到的地方就可以调用我们的函数来生成 CSS 字符串了。

---
import { generateUno } from '@/scripts/uno';

const r = `<span class="text-red-600">红色</span>`;
const y = atob('PHNwYW4gY2xhc3M9InRleHQteWVsbG93LTYwMCI+eWVsbG93PC9zcGFuPg==');

const style = await generateUno(y);

export type Props = {};
---

<style is:global is:inline is:raw set:html={style} />

<div set:html={r} />
<div set:html={y} />
<div class="text-blue-600">蓝色</div>
渲染结果
