Transformer template for FME Packages

This is a Cookiecutter template for use with Safe Software's FME. This template is for an FME Package containing a single Python-based transformer for FME 2023 and newer. It prompts for some values and generates an FME Package directory structure.

Note that even though this template may specify a minimum_fme_build of 23224, build 24145 or newer is required when running on FME Flow.

Usage

First, install Cookiecutter:

$ pip install cookiecutter

Then, tell Cookiecutter to load this template:

$ cookiecutter https://github.com/safesoftware/fpkg-transformer-template.git

You'll be prompted to enter a series of values to fill in the template. cookiecutter.json contains all the things you'll be asked.

The template includes some basic validation to ensure that the supplied parameters don't result in an invalid package structure.

Contents

The template lays down a directory with the name of your package_uid. Inside are the contents of an FME Package, ready to be extended.

If all default parameters of the template were accepted, this results in:

• An FME Package with publisher_uid of example and package_uid of my-package.
• A Python library named fme_demogreeter, ready for packaging as a Python Wheel.
• A transformer named DemoGreeter in the Integrations category, which calls the fme_demogreeter Python module. The transformer and its Python module have a simple example of getting and setting attributes.
• A placeholder icon.png for the package, which can be replaced or deleted.

Next steps

1. Install Python dev dependencies: In a terminal, navigate to the Python package directory and run pip install -e .[dev].
2. Vendorize fmetools: This template's Python code requires a private copy of the fmetools library. Install it by running python-vendorize in the Python package directory. This installs fmetools based on the settings in vendorize.toml.
3. Make an .fpkg: FME Package projects need to be converted to .fpkg files for use with FME Workbench. To create an .fpkg file, use the fme-packager tool.

Make an .fpkg

FME works with .fpkg files instead of FME Package directories. To create an .fpkg file, use the fme-packager tool.
