flatten-repo 0.2.0

Export a repository into LLM-friendly Markdown or JSONL.

Flatten Repo

Export a repository into LLM-friendly Markdown (.md) or chunked JSONL (.jsonl).

What It Does

flatten-repo scans a project, applies include/exclude filters, and generates:

• md: a human-readable project export (tree + per-file blocks)
• jsonl: chunked records for ingestion pipelines (RAG, indexing, search)

It prefers git ls-files to respect Git tracking, with filesystem fallback when needed.

Installation

From PyPI:

pip install flatten-repo

From source (editable):

pip install -e ".[dev]"

CLI Usage

flatten-repo --help
flatten-repo --version

Common examples

Export source-focused markdown:

flatten-repo --repo . --output repo_export.md

Export full repository to JSONL:

flatten-repo --repo . --all --format jsonl --output corpus.jsonl

Include tests and add custom filters:

flatten-repo \
  --repo . \
  --output out.md \
  --include-tests \
  --include-glob "src/**/*.py" \
  --exclude-glob "**/*.png"

Export Python files without docstrings:

flatten-repo --repo . --output out.md --strip-docstrings

Development & Quality

Run checks from the local virtualenv:

./.venv/bin/ruff check .
./.venv/bin/ruff format --check .
./.venv/bin/ty check src/ tests/
./.venv/bin/pytest
./.venv/bin/pytest -m integration
./.venv/bin/pytest -m end2end

Pre-commit hooks are configured in .pre-commit-config.yaml.

Scope & Filtering Notes

• Default scope: src/ + key files (pyproject.toml, requirements, pre-commit config, etc.).
• --src-only: strict src/ scope (excludes key files).
• --tests-only: restricts export to tests/ (+ key files unless --no-key-first).
• --max-bytes: files larger than this threshold are truncated to head/tail excerpts.
• --drop: supports presets api, ci, data, docker, docs, documentation, front, README, tests.
• --strip-docstrings: removes Python module/class/function docstrings from exported content.

Markdown Output Notes

• The file tree is rendered under a ## Structure section.
• File section titles contain only the relative path (no size/SHA by default).

Quality Gates

• Coverage gate is configured in pyproject.toml (fail_under = 30).
• Unit tests remain the default pytest selection via marker configuration.

Publish To PyPI

Release checklist:

# 1) Update version in pyproject.toml + src/flatten_repo/__init__.py
./.venv/bin/ruff check .
./.venv/bin/pytest

# 2) Build artifacts
./.venv/bin/python -m build

# 3) Validate metadata and long description
./.venv/bin/python -m twine check dist/*

Dry-run on TestPyPI first:

./.venv/bin/python -m twine upload --repository testpypi dist/*
python -m pip install --index-url https://test.pypi.org/simple/ flatten-repo

Publish production release:

./.venv/bin/python -m twine upload dist/*
