Math Worksheet — 公式转图片

把口述/速记的数学题变成清晰可打印的图片。核心是一个本地实时预览页面:你把题目写成 LaTeX (一行一题)追加进一个文本文件,浏览器页面每秒自动读取并渲染,用户点按钮就能把单题复制成 PNG/SVG 贴进 Word/WPS。整套只依赖 python3 和一个浏览器,无需安装 LaTeX。

启动(每个会话第一次用时跑一次,幂等)

bash ~/.claude/skills/math-worksheet/scripts/start.sh

它会:拷贝页面与离线 MathJax 到运行目录 → 后台起 python3 -m http.server 8765 → 打开浏览器。 输出里有三行关键信息,记住 FORMULAS= 那个路径:

RUN_DIR=.../math-worksheet
FORMULAS=.../math-worksheet/formulas.txt   ← 你要写入的文件
URL=http://localhost:8765/index.html
  • 端口被占用时可换端口:start.sh 8770。
  • 已在运行则直接复用,不会重复启动。
  • 结束:bash ~/.claude/skills/math-worksheet/scripts/stop.sh。

工作循环(启动后)

用户每报一道(或一组)题,你只做一件事:把 LaTeX 写入 FORMULAS 文件(用 Write 工具, 整体覆盖即可),页面 1 秒内自动更新。一行一题。出一组题就写多行。

例如用户说“1/6 加 3/6,等号后留空”,写入:

\dfrac{1}{6}+\dfrac{3}{6}=\underline{\hspace{2cm}}

然后告诉用户“已更新,去页面点该题的 复制PNG 贴进 WPS”。不要每题再去单独生成 PNG 文件—— 复制按钮已经在页面上,这才是省事的路径。

LaTeX 写法约定(务必遵守)

| 需求 | 写法 | |---|---| | 分数 | \dfrac{a}{b} | | 答案填空线 | \underline{\hspace{2cm}}(改 cm 调长短) | | 空白分数(让学生填分子分母) | \dfrac{\hspace{1.2cm}}{\hspace{1.2cm}}(分数线即横线,不要再套 \underline) | | 带分数填空 | \underline{\hspace{1.5cm}}+\dfrac{\hspace{1.2cm}}{\hspace{1.2cm}} | | 比大小填空(填 > < =) | \;\bigcirc\;,如 \dfrac{3}{8}\;\bigcirc\;\dfrac{5}{8} | | 运算符 | + - \times \div = | | 根号 / 乘方 | \sqrt{...} x^{2} | | 括号(自动适配高度) | \left( ... \right) | | 单位(正体)+ 细空格 | \,\text{m},如 50\,\text{m}\times 30\,\text{m} | | 除法用分数线表示 | \dfrac{\,被除式\,}{\,除式\,} |

硬性规则:

  1. 不要在公式外加 $ … $,页面会自动用 $$ 包裹。
  2. 公式里不要写中文(MathJax 的数学字体没有中文字形,会显示成方块)。

需要中文标注时放在题面文字里,不要放进公式。

  1. 一行一题;空行忽略。
  2. 嵌套在 \sqrt{} 或分母里的小分数,可用 \frac(小号)让排版更紧凑。

页面上的按钮(告诉用户怎么用)

  • 复制PNG:把该题渲染成 4× 高清 PNG 写入剪贴板,去 Word/WPS Ctrl/Cmd+V 直接贴图。最稳。
  • 复制SVG:尝试把矢量 SVG 放进剪贴板;浏览器多半不允许,会自动退回复制源码文本。
  • 下载SVG:保存成 .svg 文件,再用“插入→图片”插入,可得真正矢量(新版 WPS/Word 支持)。
  • 白底/透明:切换;透明模式下复制出来的 PNG 是透明底(贴进彩色单元格不带白框)。
  • 字号滑块:调大让截图/复制更清晰。

注意

  • 剪贴板复制需要安全上下文——本页用 http://localhost 已满足。Chrome / Edge / Arc 最稳;

Firefox 对 ClipboardItem 支持弱,复制 PNG 可能失败,建议用 Chrome 系浏览器打开。

  • 用户也能脱离 AI 独立使用:在左侧文本框直接敲 LaTeX → 点“渲染”。
  • 离线可用:MathJax 库已随 skill 打包;首次若缺失会联网补下一次,之后纯离线。
