quillmark 0.50.0

Python bindings for Quillmark - template-first Markdown rendering

Quillmark — Python bindings for Quillmark

Python bindings for the Quillmark template-first Markdown rendering engine.

Maintained by TTQ.

Installation

pip install quillmark

Quick Start

from quillmark import Quillmark, Quill, ParsedDocument, OutputFormat

# Create engine
engine = Quillmark()

# Load and register a quill
quill = Quill.from_path("path/to/quill")
engine.register_quill(quill)

# Parse markdown
markdown = """---
QUILL: my_quill
title: Hello World
---

# Hello

This is a test document.
"""
parsed = ParsedDocument.from_markdown(markdown)

# Create workflow and render
workflow = engine.workflow(parsed)  # Infers quill from QUILL tag
result = workflow.render(parsed, OutputFormat.PDF)

# Save output
result.artifacts[0].save("output.pdf")

API Overview

The Python API provides opinionated visibility over the rendering workflow:

1. Load Quill - Load template bundles from the filesystem
2. Parse Markdown - Parse Markdown with YAML frontmatter into ParsedDocument
3. Inspect Quill - Retrieve quill properties (metadata, field schemas, supported formats)
4. Create Workflow - Build a rendering pipeline. Note that the quill reference is optional to specify and can be inferred from the markdown content's frontmatter.
5. Render - Generate output artifacts with configurable options

Core Classes

Quillmark - Engine

Manages backends and quills.

engine = Quillmark()
engine.register_quill(quill)
engine.registered_backends()  # ['typst']
engine.registered_quills()    # ['my_quill']

# Create workflows
workflow = engine.workflow(parsed)          # Infer from QUILL tag
workflow = engine.workflow("name")          # By name (latest version)
workflow = engine.workflow("name@1.0")      # By reference (specific version)
workflow = engine.workflow(quill)           # By object

# Retrieve registered quills
quill = engine.get_quill("name")            # Get latest version
quill = engine.get_quill("name@1.0")        # Get specific version

Quill - Template Bundle

Represents a quill loaded from the filesystem.

quill = Quill.from_path("path/to/quill")

# Properties
quill.name              # Quill name
quill.backend           # Backend identifier (e.g., "typst")
quill.plate             # Template content (optional)
quill.example           # Example markdown content (optional)
quill.metadata          # Quill metadata dict
quill.schema            # Field schema definitions
quill.defaults          # Default field values from schema
quill.examples          # Example field values from schema
quill.supported_formats()  # [OutputFormat.PDF, OutputFormat.SVG]

ParsedDocument - Parsed Markdown

Represents parsed Markdown with frontmatter.

parsed = ParsedDocument.from_markdown(markdown)

parsed.body()           # Document body (str | None)
parsed.quill_ref()      # Quill reference string (str)
parsed.get_field(key)   # Get specific field (Any | None)
parsed.fields           # All frontmatter fields (dict)

Workflow - Rendering Pipeline

Sealed workflow for rendering.

workflow = engine.workflow("my_quill")

# Render
result = workflow.render(parsed, OutputFormat.PDF)

# Query properties
workflow.quill_ref            # "my_quill@1.0"
workflow.backend_id           # "typst"
workflow.supported_formats    # [OutputFormat.PDF, OutputFormat.SVG]

Note: Dynamic asset and font injection is not currently supported in Python bindings. Assets must be included in the quill bundle.

RenderResult - Output Container

Contains rendered artifacts and diagnostics.

result = workflow.render(parsed, OutputFormat.PDF)

for artifact in result.artifacts:
    print(f"Format: {artifact.output_format}")
    print(f"Size: {len(artifact.bytes)} bytes")
    artifact.save("output.pdf")

for warning in result.warnings:
    print(f"{warning.severity}: {warning.message}")

Development

This repository uses uv for local development (https://astral.sh/uv).

Install uv (one-time):

curl -LsSf https://astral.sh/uv/install.sh | sh

Canonical development flow:

# Create virtual environment
uv venv

# Install developer extras (includes maturin, pytest, mypy, ruff)
uv pip install -e ".[dev]"

# Run tests
uv run pytest

Alternative: Without uv

# Create venv
python3 -m venv venv
source venv/bin/activate

# Install dependencies
pip install maturin pytest

# Build and install
maturin develop

# Run tests
pytest
