wechat-md
Markdown → 微信公众号 HTML 渲染器。
输出全部行内 style、零 class、零外部 CSS 的 HTML，粘贴进微信公众号编辑器即为最终排版——标题、代码块、表格、引用、列表样式完整保留，不依赖任何外部资源。
为什么需要它
微信公众号编辑器会过滤 class 属性与外部样式表。通用 Markdown 渲染器输出的高亮 class 会被 strip，导致代码块排版错乱；依赖外部 CSS 的主题在公众号里整体失效。
wechat-md 针对公众号编辑器逐项适配，所有样式内联在元素上，输出即终稿。
安装
pip install wechat-md
生产环境锁定版本（升级是显式决策，不隐性漂移）：
pip install wechat-md==0.4.0
引用 GitHub 源时锁 tag（.../archive/refs/tags/vX.Y.Z.tar.gz），不要引滚动的 main。
快速开始
from wechat_md import markdown_to_html
html = markdown_to_html("# 标题\n\n正文…")
返回的 HTML 可直接作为公众号草稿正文提交，或粘贴进编辑器。
主题（可选）
传入 theme 即可按主题配色渲染（键与 wechat-publish-service 的 ThemeConfig 对齐）：
html = markdown_to_html(
md,
theme={"h1_color": "#3498db", "h2_color": "#3498db", "strong_color": "#3498db"},
)
支持键：h1_color / h2_color / h3_color / strong_color / quote_bg /
quote_border / code_bg / code_font_size / text_color。未提供或未知键保持默认；
不传 theme 时输出与历史版本逐字节一致。
排版规则
| Markdown 元素 | 公众号渲染效果 |
|---|---|
| 文首 H1 | 移除（标题由草稿字段承载，正文不重复） |
| H1 / H2 | 加粗 + 左侧红色竖条（border-left，复制时不产生多余换行） |
| H3 | ▪ 前缀加粗 |
| 代码块 | 灰底圆角卡片、等宽字体、缩进以 保留 |
| 引用块 | 灰底 + 左红边卡片 |
| 表格 | 全边框、表头灰底 |
| 链接 | 公众号蓝（#576b95）、可点击 |
| 列表 | 行内样式，并修复渲染器把 - 行并进段落的伪列表问题 |
--- 分隔线 |
移除（编辑器渲染为冗余灰线） |
| 连续「角色名:」行 | 自动聚合成对话卡片 |
| 标题后紧跟加粗小节 | 自动聚合成结论区卡片 |
设计约束
- 纯函数、无网络、无配置——
markdown_to_html(text, theme=None)一个入口；主题为可选配色字典，由调用方传入。 - 唯一运行时依赖
markdown2（未安装时自动回退markdown）。 - 兼容 Python 3.9+。
开发
pip install -e ".[dev]"
pytest
质量门：ruff（E,W,F,I,B,C4,UP,SIM）+ mypy --strict + pytest 全绿后才发版。
