regex search capability within Jinja template

[rajeshbadveti]

Hello Team,
I am looking for help to perform regex operation within jinja template.

For example, below are the commands that will be included in template:

sms all status:

SMS server
Enabled: true
Status: running PID:29157 for 1377474s

SMS server rate
Enabled: true
Status: running PID:27468 for 1377466s

SMS server rate limit
Enabled: true
Status: running PID:27468 for 1377466s

sms server rate:

SMS server rate
Enabled: true
Status: running PID:27468 for 1377466s

sms server status:

SMS server
Enabled: true
Status: running PID:29157 for 1377474s

Jinja template:

{
"TEMPLATE-1" : 
	{ 
		"node_types" : [ "node1" ],
		"node_commands" : [ "sms all status", "sms server rate", "sms server status" ],
		"node_regex_commands": ["{{regex_search('Enabled: (.*)'), node_command_output2}}"]
	}
}

When the node_commands are executed, we store the output of each into the variable as node_command_output(X)
The output of the command sms server status will be stored in variable node_command_output2

We want to apply regex to get the value Enabled flag

{
"TEMPLATE-1" : 
	{ 
		"node_types" : [ "node1" ],
		"node_commands" : [ "sms all status", "ifconfig", "sms server status" ],
		"node_regex_commands": ["{{regex_search('Enabled: (.*)'), node_command_output2}}"]
	}
}

Expected output, when we print the node_regex_commands:

>> print(node_regex_commands)
      true

Please let us know if this can this be achieved ?

Thank you!

We managed to get around it with jinja2 custom filters but would like to hear if there are any other solutions ?

Thanks,

Custom filters seem to be a good choice for such custom functionality. What other solution are you looking for?

Thank you!

I came across this URL https://docs.pexip.com/admin/jinja_templates.htm#custom_filters

Question: Why Jinja does not support such inbuilt capability like pex_regex_search('regex pattern', 'string_to_search') ?
