Call EvaluateAsync

[bakman23]

Hello,
is it possible to raise only this method when I call my custom function ?

` protected override async Task EvaluateAsync(ParsingScript script)
{
List args = script.GetFunctionArgs();
Utils.CheckArgs(args.Count, 1, m_name);

        var url = Utils.GetSafeString(args, 0);
        Variable results = await HttpGet(url);

        return results;
    }`

Thanks :)

Hey, sure. If you provide me with more details around it and what you are trying to achieve, I can try to help you... Thanks, Vassili

Thanks fr your response,
the case is simple I have a custom function and I need to call an async method in the method Evaluate.
I see it's possible to override EvaluateAsync, but I don't know how and when this method is called.

I find a solution,
Call directly EvaluateAsync from Evaluate method like that:

`
protected override Variable Evaluate(ParsingScript script)
{
return EvaluateAsync(script).Result;
}

    protected override async Task<Variable> EvaluateAsync(ParsingScript script)
    {
        List<Variable> args = script.GetFunctionArgs();
        Utils.CheckArgs(args.Count, 1, m_name);

        var url = Utils.GetSafeString(args, 0);
        Variable results = await HttpGetAsync(url);

        return results;
    }

`
Is it correct ?

Can you send the whole class, including its name and how it’s registered with the parser (if registered)?

`
class Api {

    public static void Init()
    {
        ParserFunction.RegisterFunction("ApiGet", new ApiGetFonction());
    }

}

class ApiGetFonction : ParserFunction
{
    protected override async Task<Variable> EvaluateAsync(ParsingScript script)
    {
        List<Variable> args = script.GetFunctionArgs();
        Utils.CheckArgs(args.Count, 1, m_name);

        var url = Utils.GetSafeString(args, 0);
        Variable results = await HttpGetAsync(url);

        return results;
    }

    protected override Variable Evaluate(ParsingScript script)
    { 
        return EvaluateAsync(script).Result;
    }

    public async Task<Variable> HttpGetAsync(string url) {

        HttpClient client = new HttpClient();
        HttpResponseMessage response = await client.GetAsync(url);
        response.EnsureSuccessStatusCode();
        string responseBody = await response.Content.ReadAsStringAsync();


        Variable results = new Variable(Variable.VarType.STRING);

        results.AddVariable(new Variable(responseBody));

        return results;
    }


}

`

And the registration is in Interpreter.cs -> RegisterFunctions()

Api.Init();

Basically you don't need to override anything. First you register your class with the parser as follows: ParserFunction.RegisterFunction("ApiGet", new ApiGetFonction()); You already do this. So now every time the parser parses ApiGet(); the code in EvaluateAsync() will be triggered. So to change the functionality you just change the contents of EvaluateAsync() method. Let me know if I understand your question right. Thanks, Vassili
