Template Text Parser Templates

This repository contains a collection of TTP templates.

If you solved a problem using TTP and feel that your work can be useful to other people, feel free to raise an issue or submit pull request to include your template(s) in this repository. Refer to Contribute Guide for details.

Documentation: https://dmulyalin.github.io/ttp_templates/

Repository: https://github.com/dmulyalin/ttp_templates

TTP: https://ttp.readthedocs.io/

Installation

From PyPi:

pip install ttp-templates

or latest from GitHub master branch (need Git installed on the system):

pip install git+https://github.com/dmulyalin/ttp_templates.git

Sample usage

This example demonstrates how to parse Test Platform output for show run | sec interface command using platform/test_platform_show_run_pipe_sec_interface.txt template.

Code

from ttp_templates import parse_output
import pprint

data = """
interface GigabitEthernet1/3.251
 description Customer #32148
 encapsulation dot1q 251
 ip address 172.16.33.10 255.255.255.128
 shutdown
!
interface GigabitEthernet1/3.251
 description Customer #32148
 encapsulation dot1q 251
 ip address 172.16.33.10 255.255.255.128
 shutdown
"""

result = parse_output(
    data=data,
    platform="Test Platform",
    command="show run | sec interface"
)

pprint.pprint(result)

# prints:
# [[[{'description': 'Customer #32148',
#     'disabled': True,
#     'dot1q': '251',
#     'interface': 'GigabitEthernet1/3.251',
#     'ip': '172.16.33.10',
#     'mask': '255.255.255.128'},
#    {'description': 'Customer #32148',
#     'disabled': True,
#     'dot1q': '251',
#     'interface': 'GigabitEthernet1/3.251',
#     'ip': '172.16.33.10',
#     'mask': '255.255.255.128'}]]]

Sample code to parse Cisco IOS output in a structure compatible with ietf-interfaces YANG module.

How templates collections structured

This repository contains three collections of templates corresponding to folder names:

• platform collection - mimics ntc-templates API and follows same naming rule
• yang collection - contains templates capable of producing YANG compatible structures out of text data
• misc collection - miscellaneous templates for various use cases organized in folders

Platform collection templates files naming rule

{{ vendor_os }}_{{ command_with_underscores }}.txt - lower case only.

Naming rules details:

• All space symbols ' ' replaced with underscores.
• Pipe symbol | replaced with pipe in template name. For example, template to parse Cisco IOS show run | section interface command output must be named cisco_ios_show_running_config_pipe_section_interface.txt
• Dash symbols - replaced with underscores. For example, template to parse Huawei display current-configuration interface command output must be named huawei_display_current_configuration_interface.txt

YANG collection templates files naming rule

{{ YANG module name }}_{{ platform_name }}.txt - lower case only

Naming rules details:

• All space symbols ' ' replaced with underscore.
• Dash symbol - does not replaced with underscore. For example, template to produce output compatible with openconfig-lldp YANG model for Cisco IOS must be named openconfig-lldp_cisco_xr.txt

Misc collection templates files naming rule

{{ usecase folder }}/{{ template name }}.txt - upper or lower case

Naming rules details:

• Nothing replaced with anything, provided template name used as is.
