comet-flowtools 0.1.0

Raptor flowchart converter and Rapcode interpreter utilities.

Comet Flowtools

Utilities for working with Raptor flowcharts and Rapcode programs.

Installation

Install from PyPI:

pip install comet-flowtools

Or install from source for development:

git clone <repository-url>
cd comet
pip install -e .

Repository Layout

• src/comet_flowtools: High-level API plus modernized utility helpers (formerly the loose scripts inside python/).
• src/raptor_converter: Library + CLI for converting .rap / .rapcode files into Rapcode, Mermaid, or Graphviz outputs.
• src/rapcode_interpreter: ANTLR-based interpreter for .rapcode programs plus the generated lexer/parser artifacts.
• tests/fixtures: Minimal .rap inputs that keep the test suite self-contained.
• tests/unit: Python unit tests that cover the parser/generator stack and the public API.

The duplicate copy of raptor_converter that previously lived inside the interpreter directory has been removed. Both apps now share the same canonical package under src/.

Usage

After installation (from PyPI or source), the following command-line tools are available:

• raptor-convert path/to/flowchart.rap --to mermaid
• rapcode-run path/to/program.rapcode
• flowtools export-raptor-ast path/to/flowchart.rap -o flowchart.json

You can also run individual modules directly:

python -m raptor_converter input.rap --to mermaid
python -m rapcode_interpreter program.rapcode

Or use the unified flowtools command with subcommands.

Python API

Installing the project also exposes a comet_flowtools package that unifies the converter and interpreter capabilities behind a single import surface:

from comet_flowtools import (
    parse_raptor_file,
    parse_rapcode,
    ast_to_rapcode,
    convert_raptor_to_rapcode,
    run_rapcode,
)

# Parse a .rap XML file into the canonical AST structure.
# Note: Use absolute paths or paths relative to your working directory
program_ast = parse_raptor_file("path/to/flowchart.rap")

# Convert that AST into Rapcode text (and optionally write it to disk).
rapcode_text, _ = convert_raptor_to_rapcode(
    "path/to/flowchart.rap",
    "output.rapcode",
)

# You can also round-trip an existing .rapcode file or text snippet.
rapcode_ast = parse_rapcode(rapcode_text)

# Execute Rapcode from a string or path and capture its output.
captured = []
run_rapcode('OUTPUT "Hello!"', output_callback=captured.append, source_is_path=False)
assert captured == ["Hello!"]

Every helper returns plain dictionaries or strings so you can integrate the library into other tooling or educational workflows.

Running Tests

python -m unittest discover -s tests -t .
