Scripting get_variable method not implemented

[zDavidB]

The docs Scripting contains a reference to the posting.get_variable() method, but it doesn't look like this has been implemented (yet).

As a workaround, looks like we could use vars = posting.variables and process the dict returned.
e.g.

from posting import Posting
import json

def setup(posting: Posting) -> None:
	
	auth_token="auth_token"
	
	# Capture the variables currently set
	vars = posting.variables
	# Check to see if auth token is set
	if not auth_token in vars:
		print(f"{auth_token} not found")
		posting.set_variable(auth_token, "1234567890")
	
		# Debug - dump the updated variables
		vars = posting.variables	
		print(f"Vars: {json.dumps(vars, sort_keys=True, indent=4)}")
		
		# Debug to see the var is set.
		print(f"Auth: {vars[auth_token]}")
