Zero touch variable number of inputs on node

Michael684 · April 10, 2018, 1:12pm

Hi all!

Things have been going great thus far with node development, but there is another thing I cannot figure out. Is it possible to create a node that features a variable number of input ports, simmilar to the +/- buttons the list.create node from the Dynamo core? Or is this notoriously hard to do?

Alternatively it would also be OK to be able to check the level of the lists which are attached to my node. Now I’m using:

    public static List<Autodesk.DesignScript.Geometry.Curve> Lines(List<Autodesk.DesignScript.Geometry.Curve> DynamoCurveList)
    {
        //do stuff
    }

How would I need to change the code so that it can do stuff based on the level of the lists?

Thanks again! This forum really is a live saver

Here’s an example of such node implementation in Mandrill:

github.com

BadMonkeysTeam/Mandrill/blob/master/Mandrill_UI/NodeModels/MandrillVariableInputNode.cs

using System.Collections.Generic;
using Dynamo.Graph.Nodes;
using ProtoCore.AST.AssociativeAST;
using Dynamo.Wpf;
using System;

namespace Mandrill.ChromeWindow
{
    /// <summary>
    ///     Report
    /// </summary>
    [NodeName("Create Report")]
    [NodeDescription("Creates Mandrill Report object that can be viewed in a Window or Printed to PDF.")]
    [NodeCategory("Archi-lab_Mandrill.Report.Window")]
    [IsDesignScriptCompatible]
    [InPortNames("Chart0")]
    [InPortDescriptions("MandrillChart0")]
    [InPortTypes("Chart")]
#if Release20
    [OutPortNames("Report")]

heres another way to do it with a zero touch node:

github.com

DynamoDS/Dynamo/blob/ff17c04a4b58cf72b5e3bfe91a4cca6250054bec/src/Libraries/CoreNodes/String.cs#L96


/// <summary>
///     Concatenates multiple strings into a single string, inserting the given
///     separator between each joined string.
/// </summary>
/// <param name="separator">String to be inserted between joined strings.</param>
/// <param name="strings">Strings to be joined into a single string.</param>
/// <returns name="str">
///     A string made from the list of strings including the separator character.
/// </returns>
/// <search>join,separator,build csv,concat,construct</search>
public static string Join(string separator, params string[] strings)
{
    return string.Join(separator, strings);
}


/// <summary>
///     Converts the given string to all uppercase characters.
/// </summary>
/// <param name="str">String to be made uppercase.</param>
/// <returns name="str">Uppercase string.</returns>
/// <search>2uppercase,to uppercase,touppercase,uppercase</search>
