Receptus — from the Latin "received (text)" — is a Python CLI prompt toolkit built for humans.

It enables the creation of intelligent and secure terminal interfaces with advanced input features like:

• Option selection (single & multi)
• Free-form text input
• Input validation and transformation
• Fuzzy matching and auto-complete
• Password masking
• ANSI and ASCII-compatible output
• Timeout and retry handling
• Input history
• Event logging hooks (on_event)
• Quit/help commands
• Dynamic option lists

Installation

Receptus is a single-file drop-in module. Just copy receptus.py into your project.

You can also install it via PyPI or GitHub:

pip install receptus

pip install git+https://github.com/hustedev/receptus.git

---

Quick Start

from receptus import Receptus

prompt = Receptus()

color = prompt.get_input(
    prompt="Choose a color:",
    options={"r": "Red", "g": "Green", "b": "Blue"},
    default="g"
)

print(f"You chose: {color}")

---

Features

Prompt with Options

options = {
    "1": "Low",
    "2": "Medium",
    "3": "High"
}

choice = Receptus().get_input(
    prompt="Select difficulty:",
    options=options,
    default="2"
)

---

Free Text + Validation + Transform

def validate_port(s):
    try:
        port = int(s)
        return (0 < port < 65536, "Must be a valid port number")
    except:
        return (False, "Not a number")

def transform_port(s):
    return int(s)

port = Receptus().get_input(
    prompt="Enter port:",
    allow_free_text=True,
    validator=validate_port,
    transformer=transform_port
)

---

Multi-Select

files = Receptus().get_input(
    prompt="Select files:",
    options={"1": "fileA", "2": "fileB", "3": "fileC"},
    allow_multi=True,
    min_choices=1,
    max_choices=2
)

---

Fuzzy Match & Auto-Complete

name = Receptus().get_input(
    prompt="Enter country:",
    options={"us": "USA", "uk": "United Kingdom", "uae": "United Arab Emirates"},
    fuzzy_match=True,
    auto_complete=True
)

---

Password Masking + Timeout

secret = Receptus().get_input(
    prompt="Enter password:",
    mask_input=True,
    timeout_seconds=15
)

---

Event Logging via on_event

def logger(event_type, ctx):
    print(f"[{event_type}] -> {ctx}")

Receptus(on_event=logger).get_input(
    prompt="Choose something:",
    options={"1": "One", "2": "Two"},
)

---

Return Formats

You can control what get_input() returns:

return_format="key"     # (default) -> "1"
return_format="value"   # -> "One"
return_format="tuple"   # -> ("1", "One")

• FORCE_ASCII=1 — disables Unicode output
• NO_COLOR=1 — disables ANSI color
