    Dear Telerik,

    is there an API or documentation regarding writing code cleaning extensions? The 3 examples provided in the Telerik project contain some code examples, but not everything I could use.

    At the moment i'm looking for a way to insert a new generated line (region in this case) before another line (first property).
    Finding the property is not an issue, I think I found it. Generating a new line and inserting It though is another issue.
    Could you perhaps provide a small code example?

    Thanks in advance.

    Hello Ramon,

     Thanks for contacting us.
    Try with the following code:

    namespace JustCode.Cleaning.Example
     using System;
     using System.Collections.Generic;
     using System.ComponentModel.Composition;
     using System.Linq;
     using Telerik.JustCode.CommonLanguageModel;
     public class InsertRegionCleaningStep : CodeCleaningStepProviderModuleBase
      private const string MarkerId = "InsertRegion";
      private const string CleanOptionText = "Insert Regions";
      private const int Order = 99999;
      public override IEnumerable<CodeCleaningStep> CodeCleaningSteps
        yield return new CodeCleaningStep(LanguageNames.CSharp, Order, CleanOptionText, MarkerId);
        yield return new CodeCleaningStep(LanguageNames.VisualBasic, Order, CleanOptionText, MarkerId);
      public override void ExecuteCodeCleaningStep(CodeCleaningStep step, FileModel fileModel, CodeSpan span)
       foreach (IPropertyDeclaration property in fileModel.All<IPropertyDeclaration>())
        CodeSpan regionStartCodeSpan = new CodeSpan(property.CodeSpan.StartLine, 1, property.CodeSpan.StartLine, 1);
        fileModel.ReplaceTextually(regionStartCodeSpan, string.Format("#region Test {0}", Environment.NewLine));
        CodeSpan regionEndCodeSpan = new CodeSpan(property.CodeSpan.EndLine + 2, 1, property.CodeSpan.EndLine + 2, 1);
        fileModel.ReplaceTextually(regionEndCodeSpan, string.Format("#endregion {0}", Environment.NewLine));

    In the code above you will have to select the first property as your target code span. 

    Also I want to point you to our github JustCode extensions project where you can discover some other examples.
