prompting-press 0.2.0

Python distribution of Prompting Press — a thin wrapper around the Rust core via PyO3.

prompting-press

A typed, variant-aware prompt-template library. It turns typed inputs and a template into rendered text plus content-addressed provenance — nothing else (no I/O, no LLM calls, no request assembly). Rust, Python, and TypeScript all bind one compiled Rust engine, so rendered output is byte-identical across every language.

This is the Python distribution: a Pydantic-friendly PyO3 binding to that engine. Import name prompting_press; distribution name prompting-press.

Install

pip install prompting-press
uv add prompting-press          # in a uv project
uv pip install prompting-press  # uv's pip interface

Quick start

from prompting_press import Prompt
from pydantic import BaseModel

class Vars(BaseModel):
    name: str

greet = Prompt.from_yaml("""
name: greet
role: user
body: "Hi {{ name }}"
variables:
  name: { type: string, trusted: true }
""")

result = greet.render(Vars, data={"name": "Ada"})
result.text           # "Hi Ada"
result.template_hash  # 64-char SHA-256 of the template source
result.render_hash    # 64-char SHA-256 of the rendered output
