CLI Auto-Parser

The Genie Parsergen package (or simply parsergen) provides a one-step parsing mechanism that is capable of parsing dynamic tabular and non-tabular device outputs into noticeably fewer lines of code compared to the standard parsing mechanisms.

The Genie Parsergen package is an extension of the top-level Cisco Genie automation package, based on Cisco pyATS framework.

This package was initially developed internally in Cisco, and is now available to the general public (since early 2018) through Cisco DevNet.

For more details, refer to pyATS.
