Can't modify nodes using C#? about cwtools HOT 2 OPEN

Hi!

You're right, the interface has changed since then so that snippet doesn't work.

I've updated it so it works again.

Basically, most of the properties return read-only copies as F# has immutable data by default. There are four ways you can actually modify the data structure:

1. SetTag which will look for the key and replace it, or add it if it isn't there
2. AllChildren's setter, which takes a C# List and replaces all current children with it
3. All's setter, which takes an F# List and replaces all current children with it it
4. `AllArray', which returns a mutable array (but not resizable), or the setter which replaces all current children with it

For "Leaf", both the Key and Value have setters. For "Node", the Key has a setter too.

            //Add is_triggered_only = true
            var leaf = new Leaf(KeyValueItem.NewKeyValueItem(Key.NewKey("is_triggered_only"), Value.NewBool(true), Operator.Equals), FSharpOption<range>.None);
            myEvent.SetTag(leaf.Key, Child.NewLeafC(leaf));
            // or
            // var newChildren = myEvent.AllChildren;
            // newChildren.Add(Leaf.Create(KeyValueItem.NewKeyValueItem(Key.NewKey("is_triggered_only"), Value.NewBool(true), Operator.Equals), range.Zero));
            // myEvent.AllChildren = newChildren;

Hope that helps a little!

Thank you for the in-depth answer!

Speaking of serializing, I have another question. I'm trying to modify a Crusader Kings III file programmatically and iteratively, and since the file is quite big I'd like to pickle the parsed data between runs. Is there a way to do so?

            var processed = CWTools.CSharp.Parsers.ProcessStatements("testevent.txt", "./testevent.txt", eventFile);

            var serialized_processed = JsonSerializer.Serialize(processed);  // <--- Fails here: 			System.NotSupportedException: 'F# discriminated union serialization is not supported. Consider authoring a custom converter for the type.'
            var deserialized_processed = JsonSerializer.Deserialize<Node>(serialized_processed);
            File.AppendAllText("./serialized_node.txt", serialized_processed);
