Python tools for typed input validation.

Rynput

Python tools for strongly typed input validation.

Description

Rynput is focused on validating strings and converting them to a specific type, if possible. It is particularily effective when configuring a large list of properties which may have very different requirements for their values.

Usage

It is recommended to use the following import statement:

from rynput import Property, PropertyGroup, validators

From there, create the list of properties to validate. The constructor for Property takes a name (str), type (Validator), and optionally a default value and description. Omitting a default value means that the property is marked as "required," and thus cannot be omitted by the input method.

properties = PropertyGroup([
    Property("Option", validators.Option(["Foo", "Bar", "Baz"]), "Foo"), # Default value provided
    Property("Integer", validators.Integer(4, 8)), # Required
    ...
])

The input strings may come from anywhere. However, typical examples may include a user configuration wizard (see examples/input_example.py) or from a config file (examples/json_example.py).
