Enable git-like did-you-mean feature in click.

It’s as simple as this:

import click
from click_didyoumean import DYMGroup

@click.group(cls=DYMGroup)
def cli():
    ...

Demo

Usage

Install this extension with pip:

pip install click-didyoumean

Use specific did-you-mean group class for your cli:

import click
from click_didyoumean import DYMGroup

@click.group(cls=DYMGroup)
def cli():
    pass

@cli.command()
def foo():
    pass

@cli.command()
def bar():
    pass

@cli.command()
def barrr():
    pass

if __name__ == "__main__":
    cli()

Or you it in a CommandCollection:

import click
from click_didyoumean import DYMCommandCollection

@click.group()
def cli1():
    pass

@cli1.command()
def foo():
    pass

@cli1.command()
def bar():
    pass

@click.group()
def cli2():
    pass

@cli2.command()
def barrr():
    pass

cli = DYMCommandCollection(sources=[cli1, cli2])

if __name__ == "__main__":
    cli()

Change configuration

There are two configuration for the DYMGroup and DYMCommandCollection:

Parameter	Type	Default	Description
max_suggestions	int	3	Maximal number of did-you-mean suggestions
cutoff	float	0.5	Possibilities that don’t score at least that similar to word are ignored.

Examples

@cli.group(cls=DYMGroup, max_suggestions=2, cutoff=0.7)
def cli():
    pass

... or ...

cli = DYMCommandCollection(sources=[cli1, cli2], max_suggestions=2, cutoff=0.7)
