Hierarchical Configuration (hier-config)

Hierarchical Configuration, or hier-config, is a Python library designed to query and compare network device configurations. It parses configuration text into a hierarchical tree to perform deterministic, line-level diffs that respect vendor syntax rules. This allows it to generate precise remediation commands to bring a device into compliance with an intended configuration. The library is actively maintained, with its current version being 3.6.0, and new releases occurring regularly.
