Traitlets module for pathlib.

Project description

traitlets_paths

Traitlets module for pathlib

This package defines traitlets for all pathlib objects.

Getting Started

Install from pip:

pip install traitlets_paths

Basic Example

from traitlets import HasTraits, default
from traitlets_paths import PurePath

class Foo(HasTraits):
    path = PurePath()

    @default('path')
    def _default_path(self):
        return 'path/to/foo'


foo = Foo()
foo.path
# On Posix systems
PurePosixPath('path/to/foo')

# or on Windows systems
PureWindowsPath('path/to/foo')

How to get a TraitError

When we try passing a bad type:

foo = Foo(path=5)

we get a TraitError:

TraitError: The 'path' trait of a Foo instance must be a pathlib.PurePath trait, but a value of 5 <class 'int'> was specified.
