Install
This package is part of the FlintTrade monorepo. Install via the workspace from the repo root:
uv pip install -e packages/services/dittoIf you only want to use the package in isolation, the package's pyproject.toml,
Cargo.toml, or package.json lists its dependencies. The supported path is the
root workspace.
Tests
python -m pytest packages/services/ditto/tests/ -v --import-mode=importlibRun one command per line. They work unchanged in bash, zsh and Windows
PowerShell — do not join them with &&, which Windows PowerShell 5.1 does not
support.
