Typer: 一个非常好用的命令行应用库
Typer, build great CLIs. Easy to code. Based on Python type hints.
今天偶然看到GitHub上一个python开源项目——Typer,可以帮助简单快速地构建命令行应用。正如介绍所说,“users will love using and developers will love creating”。
The key features are:
Intuitive to write: Great editor support. Completion everywhere. Less time debugging. Designed to be easy to use and learn. Less time reading docs.
Easy to use: It’s easy to use for the final users. Automatic help, and automatic completion for all shells.
Short: Minimize code duplication. Multiple features from each parameter declaration. Fewer bugs.
Start simple: The simplest example adds only 2 lines of code to your app: 1 import, 1 function call.
Grow large: Grow in complexity as much as you want, create arbitrarily complex trees of commands and groups of subcommands, with options and arguments.
