python-hcl2

Python HCL2 is a parser for HashiCorp Configuration Language version 2 (HCL2) written in Python using the Lark parsing toolkit. It allows developers to read, write, query, and manipulate HCL2 configuration files—such as those used by Terraform—directly from Python code or via command-line tools. ## Key Features - **HCL2 Parsing** — Converts HCL2 configuration files into Python dictionaries and vice versa. - **CLI Tool Suite** — Includes `hcl2tojson` and `jsontohcl2` for format conversion, plus `hq` for jq-like querying of HCL files. - **Programmatic Building** — Provides a `Builder` API to construct HCL2 documents from scratch within Python. - **Document Querying** — Offers `DocumentView` and `BlockView` for structured traversal and inspection of parsed HCL trees. - **Pipeline Architecture** — Supports advanced parsing pipelines with customizable stages for preprocessing and transformation. ## Philosophy The project focuses on providing a robust, Python-native interface to HCL2 that prioritizes correctness, usability, and extensibility for infrastructure-as-code workflows.
