Espanso LaTeX 简写语法说明

Espanso LaTeX 简写语法说明#

什么是 Espanso#

Espanso ↗ 是一个开源、跨平台的系统级文本展开器。它可以在任何应用程序中（包括 Typora）监听你输入的缩写，并自动替换为完整的文本。

利用 Espanso，可以用极短的缩写快速输入 LaTeX 数学公式，避免手打 \frac{}{}、\sum_{i=1}^{n} 等冗长命令。

安装与配置#

从 espanso.org ↗ 下载安装
配置文件位于 C:\Users\<用户名>\AppData\Roaming\espanso\
简写规则文件：match\latex-math.yml
修改配置后执行 espanso restart 生效

使用规则#

所有触发词以分号 ; 开头，避免与正常输入冲突
输入触发词后，Espanso 会自动将其替换为对应的 LaTeX 命令
在 Typora 的 $...$ 或 $$...$$ 数学环境内使用
