How to make typer traceback look normal

问题

当使用 typer 解析CLI参数时,我得到了非常冗长和多彩的错误消息。如何获取普通的Python回溯?请参见以下示例回溯的屏幕截图(仅显示前几行),以了解冗长风格的示例:

   27       .select(

When using typer to parse CLI arguments, I get very verbose and colorful error messages. How can I get a normal Python traceback?

See screenshot for an example traceback (just the first few lines) for illustration of the verbose style:

 python scripts/add_priors.py             
╭─────────────────────────────── Traceback (most recent call last) ────────────────────────────────╮

   23    import polars as pl                                                                     
   24                                                                                            
   25    priors = (

   27       .select(                                                                            
   28          [

如果您没有使用子命令,即只使用 typer.run(main),那么无论如何都要创建一个 typer 实例并显式运行 main 命令。
例如:

app = typer.Typer(pretty_exceptions_enable=False)
app.command()(main)
app()

注意:我本来打算将其留在接受答案的下方作为注释,但我不能在注释中添加多行,并且Python对于空格/换行符要求严格。

英文:

Also, if you're not using sub-command. i.e. using just typer.run(main) then create an instance of typer regardless and run the main command explicitly.
e.g.

app = typer.Typer(pretty_exceptions_enable=False)
app.command()(main)
app()

Note: I was going to leave it as comment below accepted answer but I can't add multiple lines in comment and python is picky about spaces/newlines.

你可以通过设置环境变量 _TYPER_STANDARD_TRACEBACK=1 来一次性禁用它。

在初始化 typer 时,可以通过传递参数 pretty_exceptions_enable=False 来禁用丰富的异常:

import typer

app = typer.Typer(pretty_exceptions_enable=False)

@app.command()
def main():
    raise Exception("test")

if __name__ == "__main__":
    app()

查看文档以获取更多选项。

英文:

You can disable it on a one-off basis by setting the environment variable _TYPER_STANDARD_TRACEBACK=1.

Disabling rich exceptions is possible by passing the kwarg pretty_exceptions_enable=False when initializing typer:

import typer

app = typer.Typer(pretty_exceptions_enable=False)

@app.command()
def main():
    raise Exception(&quot;test&quot;)

if __name__ == &quot;__main__&quot;:
    app()

See the documentation for more options
