pytypeform 0.2.3

A Type-Safe UI/CLI Generator powered by Pydantic.

Typerform

A Type-Safe UI/CLI Generator powered by Pydantic and Prompt-Toolkit.

Typerform transforms your Pydantic models into professional, interactive CLI wizards. Stop writing boilerplate input loops and manual validation—let your schemas drive the user experience.

Features

Feature	Description
Zero Boilerplate	Just one line of code to generate an entire multi-step wizard.
Type-Safe	Inherits all constraints (min_length, ge, EmailStr) from Pydantic.
Backtracking	Full backtracking support—type :b or :back to edit previous fields.
Conditional Logic	Dynamically skip fields based on previous answers using 'when' metadata.
Secure by Default	Automatic masking for SecretStr fields (API keys, passwords).
Enterprise Ready	Pluggable prompt engines for 100% automated testing in CI/CD.
Smart Autocomplete	Fuzzy search and real-time suggestions for Enums and Literals.
Hydration	Pre-fill forms from Environment variables or configuration files.

Installation

pip install pytypeform

Quick Start

from typing import Literal
from pydantic import BaseModel, Field
from typeform import form

class SetupConfig(BaseModel):
    project_name: str = Field(description="Project Name", min_length=3)
    environment: Literal["dev", "staging", "prod"] = Field(default="dev")
    enable_telemetry: bool = Field(default=True, description="Enable Telemetry")

# Generate the wizard!
config = form(SetupConfig, title="Project Setup")

print(config.model_dump())

Advanced Usage

Backtracking and Navigation

Typerform maintains a navigation stack. At any prompt, you can use special commands:

• :back or :b - Move to the previous field.
• :? - Show extended help text (if provided in json_schema_extra).

Conditional Logic

Hide or show fields dynamically based on the current state of the form:

class CloudConfig(BaseModel):
    provider: Literal["aws", "gcp"]
    # Only asked if provider is 'aws'
    aws_region: str = Field(
        "us-east-1", 
        json_schema_extra={"when": "provider == 'aws'"}
    )

Collection Wizard (Lists)

Typerform handles List[T] by entering a collection loop:

class Team(BaseModel):
    members: list[str] = Field(description="Team Members")

# User will be prompted to add multiple items sequentially.

Hydration (Auto-filling)

Speed up workflows by pre-filling fields from the environment:

import os
config = form(MyModel, hydrate_from=[os.environ])
