Ric*_*ich 2 python python-click python-3.8
我试图弄清楚如何对 Click 中的命令进行分类,以类似于kubectl其分隔命令的方式所使用的结构。
例如,在普通的 Click 帮助输出中,我们有:
Usage: cli.py [OPTIONS] COMMAND [ARGS]...
A CLI tool
Options:
-h, --help Show this message and exit.
Commands:
command1 This is command1
command2 This is command2
command3 This is command3
command4 This is command4

相反,对我的使用来说最理想的是进行分离以更好地对命令结构进行分类。
例如:
Usage: cli.py [OPTIONS] COMMAND [ARGS]...
A CLI tool
Options:
-h, --help Show this message and exit.
Specific Commands for X:
command1 This is command1
command2 This is command2
Specific Commands for Y:
command3 This is command3
command4 This is command4
Global Commands:
version Shows version

为此,我也使用最新的 Python 和最新版本的 Click。
我尝试过挂钩各种 Click 类来改变这种行为,但没有成功。我最接近的是能够根据优先级构建命令,但我无法像上面的示例一样在逻辑上将它们分开。
任何帮助将不胜感激。
我通过创建自己的实现来实现这一目标click.Group:
class OrderedGroup(click.Group):
def __init__(self, name=None, commands=None, **attrs):
super(OrderedGroup, self).__init__(name, commands, **attrs)
self.commands = commands or collections.OrderedDict()
def list_commands(self, ctx):
return self.commands
def format_commands(self, ctx, formatter):
super().get_usage(ctx)
formatter.write_paragraph()
with formatter.section("Specific Commands for X:"):
formatter.write_text(
f'{self.commands.get("command1").name}\t\t{self.commands.get("command1").get_short_help_str()}')
formatter.write_text(
f"{self.commands.get('command2').name}\t\t{self.commands.get('command2').get_short_help_str()}")
with formatter.section("Specific Commands for Y:"):
formatter.write_text(
f'{self.commands.get("command3").name}\t\t{self.commands.get("command3").get_short_help_str()}')
formatter.write_text(
f'{self.commands.get("command4").name}\t\t{self.commands.get("command4").get_short_help_str()}')
with formatter.section("Global Commands"):
formatter.write_text(
f'{self.commands.get("version").name}\t\t{self.commands.get("version").get_short_help_str()}')

并创建了cli这样的组:
@click.group(cls=OrderedGroup)
def cli():
pass

这有帮助吗?
