lapidary-render 0.8.0

Python async OpenAPI client library generator

Code generator

Installation

lapidary-render requires python 3.9 or higher to run.

I recommend installing via pipx

pipx install lapidary-render

You can set python version for lapidary with pipx install --python [path-to-python] lapidary-render. See pipx install --help for details.

Usage

lapidary command offers inline help and shell command completion. See lapidary --help for details.

lapidary init

lapidary init [--[no-]format-strict] [--[no-]render] SCHEMA_PATH PROJECT_ROOT PACKAGE_NAME

Lapidary will create

• PROJECT_ROOT and all necessary directories,
• __init__.py files,
• pyproject.toml with poetry configured,
• py.typed
• client.pyi with function stubs for all operations and a client.py with an empty client class.
• Pydantic model classes for each schema.

All python files are generated in PROJECT_ROOT/gen directory.

If a directory PROJECT_ROOT/src/patches exists, Lapidary will read all yaml files and apply them as JSONPatch against the original openapi file.

If the original openapi file is not compatible with Lapidary, running lapidary init --no-render ... will generate only the project structure without any models or stubs. Once you've prepared the patch, run lapidary update.

lapidary update

lapidary update [--[no-]format-strict] [--[no-]cache] [PROJECT_ROOT]

Default PROJECT_ROOT is the current directory.

The command

• deletes PROJECT_ROOT/gen directory,
• re-applies patches to openapi file
• and generates python files

lapidary version

lapidary version

Prints the programs version and exits.

Configuration

Lapidary can be configured with a pyproject.yaml file, under [tool.lapidary] path.

Only package value is required, and it's set by lapidary init.

• package [str] - root package name
• format [bool] - whether to format the generated code with black [default = True].
• cache [bool] - whether to cache openapi and patches as pickle files. Only files larger than 50kB are cached [default = True].
• src_root [str] - sources root, in PROJECT_ROOT [default = 'src'].
• gen_root [str] = generated sources root, in PROJECT_ROOT [default = 'gen'].
• patches [str] = patches directory, under sources root [default = 'patches'].
