fme-packager: FME Package Creator
fme-packager is a Python command-line tool for validating and creating FME Packages.
Give it the path to an FME Package directory, and it'll do some quick checks
and build an .fpkg file out of it.
The validations done by fme-packager will catch common mistakes in package development,
but is still very basic. The FME Packages it creates will be
validly formed according to the FME Packages Specification,
but whether the installed components function correctly within FME is not in its scope.
Install
Download the latest whl distribution from the releases page. Then install it:
$ pip install [fme-packager].whl
Once installed, the fme-packager command is available on your system.
fme-packager --help shows an overview of commands.
What it does
- Validate package.yml against the FME Packages Specification.
- Verifies that components listed in package.yml are present.
- Checks that transformer and format names are valid and well-formed.
- Verifies that the transformer version in the package.yml is included in the FMX/FMXJ.
- Verifies FMXJ schema compliance.
- Requires that Custom Transformers be Linked Always, declare Python 3 support, and authored with a sufficiently recent version of FME Workbench.
- Excludes components that are present in directories, but not listed in package.yml.
- Cleans and rebuilds wheels for Python packages that are subdirectories of
python/. - Copies wheels from
python/*/distintopython/. - Enforces required package icon dimensions.
These steps are done while copying files into a temporary build directory, so existing files are not modified.
Get started with a template
fme-packager init [template name] helps you get started with developing FME Packages by
using Cookiecutter templates.
Available templates:
transformer: Transformer template for FME Packages
These templates are not bundled with fme-packager.
Make an fpkg distribution
Call fme-packager pack with the path to your package directory (it contains package.yml):
$ fme-packager pack my-package
If everything went well, the fpkg will be in my-package/dist/.
