cloup.constraints.common.param_value_is_set(param: click.Parameter, value: Any) → bool[source]

Defines what it means for a parameter of a specific kind to be “set”.

All cases are obvious besides that of boolean options: - (common rule) if the value is None, the parameter is unset; - a parameter that takes multiple values is set if at least one argument is provided; - a boolean flag is set only if True; - a boolean option is set if not None, even if it’s False.

Parameters

  • param (click.core.Parameter) –

  • value (Any) –

Return type

bool

cloup.constraints.common.get_params_whose_value_is_set(params: Iterable[Parameter], values: Dict[str, Any]) → List[Parameter][source]

Filters params returning only the parameters that have a value. Boolean flags are considered “set” if their value is True.

Parameters

  • params (Iterable[click.core.Parameter]) –

  • values (Dict[str, Any]) –

Return type

List[click.core.Parameter]

cloup.constraints.common.get_required_params(params: Iterable[Parameter]) → List[Parameter][source]
Parameters

params (Iterable[click.core.Parameter]) –

Return type

List[click.core.Parameter]

cloup.constraints.common.get_param_label(param: click.Parameter) → str[source]
Parameters

param (click.core.Parameter) –

Return type

str

cloup.constraints.common.join_param_labels(params: Iterable[Parameter], sep: str = ', ') → str[source]
Parameters

  • params (Iterable[click.core.Parameter]) –

  • sep (str) –

Return type

str

cloup.constraints.common.param_label_by_name(ctx, name: str) → str[source]
Parameters

name (str) –

Return type

str

cloup.constraints.common.param_value_by_name(ctx: click.Context, name: str) → Any[source]
Parameters

  • ctx (click.core.Context) –

  • name (str) –

Return type

Any
