This module implements a parser, intended to be used for converting human readable text, such as command output from a router CLI, into a list of records, containing values extracted from the input text. A simple template language is used to describe a state machine to parse a specific type of text input, returning a record of values for each input entity. � )�absolute_import)�division)�print_function)�unicode_literalsN)�object��str)�zipc @ s e Zd ZdZdS )�ErrorzBase class for errors.N��__name__� __module__� __qualname__�__doc__� r r �~/root/rpmbuild/BUILDROOT/imh-python39-modules-3.9.7-92.el8.x86_64/opt/imh-python/lib/python3.9/site-packages/textfsm/parser.pyr , s r c @ s e Zd ZdZdS )�Usagez Error in command line execution.Nr r r r r r 0 s r c @ s e Zd ZdZdS )� TextFSMErrorz!Error in the FSM state execution.Nr r r r r r 4 s r c @ s e Zd ZdZdS )�TextFSMTemplateErrorz Errors while parsing templates.Nr r r r r r 8 s r c @ s e Zd ZdZdS )� FSMActionz+Base class for actions raised with the FSM.Nr r r r r r > s r c @ s e Zd ZdZdS )� SkipRecordz#Indicate a record is to be skipped.Nr r r r r r B s r c @ s e Zd ZdZdS )� SkipValuez"Indicate a value is to be skipped.Nr r r r r r F s r c @ s� e Zd ZdZG dd� de�Zedd� �Zedd� �ZG dd � d e�Z G d d � d e�Z G d d � d e�Z G dd� de�Z G dd� de�Z dS )�TextFSMOptionsa� Class containing all valid TextFSMValue options.
