Python API for IntentText with Rust-core parsing by default.

The package uses @intenttext/core (Rust-backed) for parser parity and keeps Python-native rendering/query/validation helpers for Python workflows and AI stacks.

Engine controls:

• INTENTTEXT_PY_ENGINE=rust (default) to use Rust core through Node.
• INTENTTEXT_PY_ENGINE=py to force legacy Python parser.
• INTENTTEXT_PY_FALLBACK=0 to disable automatic fallback to Python parser when Rust core is unavailable.
• INTENTTEXT_PY_VALIDATE_ENGINE=rust to use Rust semantic validation through Node (default); set py to force Python compatibility mode.
• INTENTTEXT_PY_QUERY_ENGINE=rust to use Rust-backed query execution (py by default for compatibility with regex property filters).
• INTENTTEXT_PY_RENDER_ENGINE=rust to use Rust-backed HTML rendering (py by default for compatibility).
• INTENTTEXT_PY_SOURCE_ENGINE=rust to use Rust-backed to_source conversion (py by default for compatibility).
• INTENTTEXT_PY_TRUST_ENGINE=rust to use Rust-backed trust helpers (py by default for compatibility).

Install

Quick Start

from intenttext import parse, render_html, merge_data, validate, query

# Parse a document
source = """
title: Sprint Planning
section: Tasks
task: Write tests | owner: Ahmed | due: Friday
task: Deploy to staging | owner: Sarah | due: Monday
gate: Final approval | approver: Lead | timeout: 24h
""".strip()

doc = parse(source)

# Query for tasks
tasks = query(doc, type="task")
for task in tasks:
    print(f"{task.content} -> {task.properties.get('owner', 'unassigned')}")

# Validate workflow semantics
result = validate(doc)
if not result.valid:
    for issue in result.issues:
        print(f"[{issue.type.upper()}] {issue.message}")

# Render to HTML
html = render_html(doc)

API

• parse(source: str) -> IntentDocument
• parse_safe(source: str, ...) -> ParseResult
• render_html(doc: IntentDocument, include_css: bool = True) -> str
• render_print(doc: IntentDocument) -> str
• render_markdown(doc: IntentDocument) -> str
• merge_data(template: IntentDocument, data: dict) -> IntentDocument
• parse_and_merge(template_source: str, data: dict) -> IntentDocument
• validate(doc: IntentDocument) -> ValidationResult
• query(doc: IntentDocument, ...) -> list[IntentBlock]
• to_source(doc: IntentDocument) -> str

Development

pip install -e .[dev]
pytest
