Git workflow

Day-to-day work happens on develop; master is ff-merged when Development CI is green (A2C development-workflow.md).

git checkout develop

Quick start

pip install -e ".[dev]"
pre-commit install
pre-commit install --hook-type commit-msg

From a deck project directory (see examples/deckicorn-hello/deckicorn.yaml):

cd examples/deckicorn-hello
deckicorn build
deckicorn preview          # requires pip install -e ".[runtime]"
deckicorn preview --show-bounds
deckicorn package --clean  # requires pip install -e ".[runtime,packaging]"

Ad hoc paths (without deckicorn.yaml):

deckicorn build examples/deckicorn-hello/deck.md \
  --layout examples/deckicorn-hello/layout-default.yaml \
  --out examples/deckicorn-hello/build/deck-spec.yaml
deckicorn run examples/deckicorn-hello/build/deck-spec.yaml
