ORM-Events
Attemptes to recreate C# getter/setter wich will generate events docs.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/using-properties https://docs.microsoft.com/en-us/dotnet/standard/events/
Usage
- See demo.py for serialization, de-serialization, and format conversion examples.
To Run the demo:
# cd to the program folder
cd io_tools
# install dependencies
pip3 install -r requirements.txt
# run the script
python3 demo.py
Step by step in:
python3import io_tools as io
import json
settings = {}
vars = io.Variables(settings)
vars.debug = True
vars.go_steppy = False
vars.yaml_input_file = "pref_input_test.yaml"
vars.json_input_file = "cache.json"
# reads a file of TYPE
vars.yaml_file_contents = io.read_yaml_file(vars.yaml_input_file)
vars.json_file_contents = io.read_json_file(vars.json_input_file)
# print as pretty json
io.print_pretty(vars.json_file_contents, vars.debug, "json")
io.print_pretty(vars.yaml_file_contents, vars.debug, "json")
# print as compact json
print(vars.__dict__)
# Serialize
json_string = print(vars.__dict__)
io.write_file('cache.json', vars.__dict__, vars.debug)
# Can write CSVs as well, but only working properly on non-nested files. WIP.
csv = io.json_to_csv('cache.json')Class Methods
Datastore
Datastore is a <key>:<value> dict that accepts any types and is used for portability. It achieves this by storing all variables in a generic dictionary with the change() method overriden to be an event system.
Variables
Object that holds a list of Datastore()s,
When eneabled, the built-in go_steppy() function will pause script execution on any memory state change to provide a json formatted diff. for example:
change_value:
Triggered when any variable within the Datastore() is updated, or created.
get_current_value:
Returns the current value of a variable within the Datastore(), and triggers an event.
diff_values:
When enabled, deepdiffs the current and proposed change to the Datastore() object
