HelpFormatter 在点击
HelpFormatter in Click
我在本地模块中使用 click,我想调整帮助的显示方式:
当前输出为--help
:
Usage: __main__.py [OPTIONS] COMMAND [ARGS]...
Options:
--help Show this message and exit.
Commands:
foo Foo is a program very nice and pretty...
默认情况下,prog
名称为 __main__.py
,文本被裁剪为 78 个字符。
我发现可以使用 HelpFormatter
class 进行调整。但我不知道如何在这种情况下使用它。
当前代码:
import click
@click.group()
def main(ctx):
pass
@main.command()
def foo():
pass
click.CommandCollection(sources=[main])()
预期输出:
Usage: my_module_name [OPTIONS] COMMAND [ARGS]...
Options:
--help Show this message and exit.
Commands:
foo Foo is a program very nice and pretty and this sentence is very long.
如果您试图避免截断帮助字符串,可以通过 short_help
参数来实现。 short_help
通常源自 help
但被截断了。如果显式传递,将显示整个字符串。
显示字符串my_module_name
,可以在参数prog_name
下传递
测试代码:
import click
@click.group()
def main(ctx):
pass
@main.command(short_help='Foo is a program very nice and pretty and '
'this sentence is very long.')
def foo():
pass
main(['--help'], prog_name='my_module_name')
short_help
的结果:
Usage: my_module_name [OPTIONS] COMMAND [ARGS]...
Options:
--help Show this message and exit.
Commands:
foo Foo is a program very nice and pretty and this sentence is very long.
