Fixable

class Fixable(trait, default_value=None, unicode=False, range=True, allow_none=True, **kwargs)

Bases: Union

Fixable parameter, specified in a filename pattern.

A fixable parameter meant to work with filefinder. It can take:

1. a value of the appropriate type,

2. a string specifying a range of values, see Range,

3. a string that will be interpreted as a regular expression to match a filename part,

4. a list of values (see 1), any of which will be accepted as a valid filename part.

Parameters:

• trait (TraitType) – Trait instance.

• default_value (Any) – The default value.

• unicode (bool) – Allow string values. Default is False as this can be dangerous, any value from command line that cannot be parsed would still be allowed.

• range (bool) – If trait is Int or Float, allow to transform a string into a range of value using Range.

• allow_none (bool) – Allow None as a valid value. Default is True.

• kwargs (Any) – Arguments passed to the Union trait created.
