A python extension for parsing and evaluating terraform using defsec.
While terraform uses HCL as its configuration format, it requires numerous forms of variable interpolation, function and expression evaluation, which is beyond the typical usage of an hcl parser. To achieve compatibility with the myriad real world usages of terraform, this library uses the canonical implementation from terraform, along with the interpolation and evaluation from defsec to offer a high level interface to parsing terraform modules.
pip install tfparse
We currently distribute binaries for MacOS (x86_64, arm64) and Linux (x86_64, aarch64) and Windows.
Note on Windows we currently don't free memory allocated on parse results.
A terraform module root, with terraform init having been performed to resolve module references.
from tfparse import load_from_path
parsed = load_from_path('path_to_terraform_root')
print(parsed.keys())
- requires Go >= 1.18
- requires Python >= 3.10
Installing will build the module and install the local copy of tfparse in to the current Python environment.
> pip install -e .
> python
>>> from tfparse import load_from_path
>>> parsed = load_from_path('<path_to_terraform>')
>>> print(parsed.keys())Building will produce a wheel and a source artifact for distribution or upload to package repositories.

pytestYou can test our cross compiling CI/CD builds by running the following:
CIBW_BUILD=cp310* cibuildwheel --platform macos --archs x86_64
This will try to build an intel wheel on python3.10
