parody 0.19.0

Unified book/notebook authoring toolchain: pandoc markdown + executed jupytext sources to JSON artifact, HTML preview, and print PDF

parody

A play on parity: keeping the print and web versions of a work in parity.

One authoring toolchain for books and course notebooks: pandoc markdown (with executed jupytext code cells) in, multiple targets out —

• JSON artifact (schema-versioned; the contract consumed by ricopic.one's Django importer and other tools)
• standalone HTML preview (no server needed; resolves the artifact's site-template tags itself)
• print-quality PDF via LaTeX profiles (lualatex/latexmk; generic profile bundled, book-private profiles pluggable)

Parody unifies and replaces the toolchains of two ancestor systems: the homepage-django notebooks pipeline and the rtc-book meta-* book machinery. See NEW_PROJECT_SEED_PLAN.md for the full plan.

Install / develop

Requires Python ≥ 3.11 and pandoc (pinned version in parody/toolchain.py), or use the Dockerfile/devcontainer.

uv sync          # create venv + install
uv run parody --help
uv run pytest    # golden tests need the ancestor corpora; see tests/golden/

CLI

parody init <dir>                          # scaffold a content repo (incl. CI workflow)
parody build <project_dir> <output.json>   # build the JSON artifact (executes code)
parody preview <project_dir> -o preview    # static HTML site for review
parody watch <project_dir>                 # rebuild on save (pip install 'parody[watch]')
parody pdf <project_dir> [--solutions] [--section ch/sec]   # print PDF (needs TeX)
parody check <artifact.json>               # validate artifact against schema
parody check --toolchain                   # verify pinned toolchain versions

Content repos use parody.yaml + chapters/<ch>/<sec>.md; the legacy System A layout (__meta.yaml + chapter_*/) builds bit-compatibly and remains covered by golden tests.
