TermCap
TermCap 是一个 Python 终端录制与渲染工具：把 PTY 会话保存为 asciicast v2，并输出 SVG 动画、静态 SVG 帧或 GIF。
核心能力
- 交互 shell 与单命令 PTY 录制
execwrapper：运行原命令时自动保存 CAST，并可直接渲染 SVG/GIF- 兼容 asciinema 的
.cast格式 - ANSI 颜色、光标、文本样式和宽字符渲染
- 模板化 SVG 动画与 16 套内置主题
- CAST→SVG、CAST→GIF、SVG→GIF
- 关键帧确定性采样和 Chrome viewport 自动校正
安装
TermCap 支持 Linux、macOS 和 BSD，需要 Python 3.8 或更高版本。GIF 导出需要 Google Chrome。
python -m pip install termcap
termcap --version
最短工作流
termcap record demo.cast -g 80x20
termcap render demo.cast demo.svg
termcap render demo.cast demo.gif --format gif
录制单条命令：
termcap record tests.cast -g 100x24 -c "python -m pytest -q"
像命令 wrapper 一样执行并录制，同时渲染 SVG：
termcap exec -g 96x16 --media-output hello.svg -- python3 -c 'print("hello")'
已有 SVG 转 GIF：
termcap svg2gif demo.svg demo.gif --speed 1 --loop 0
文档开发
