Question regarding Oxygene CodeDomProvider

What’s the best way to add assembly attributes when code is compiled using CodeDom?

We are using CodeDomProvider to generate and execute the business code layer and now I wanted to add some assembly attributes. (I know, some attributes can be specified via CompilerAttributes.)

I tried the following piece of test code, something I would do under C#:

namespace CodeGen;

interface

uses
  System.CodeDom.*,
  System.IO,
  System.Reflection;

type
  Program = class
  public
    class method Main(args: array of String): Int32;
  end;

implementation

class method Program.Main(args: array of String): Int32;
begin
  var compileUnit := new CodeCompileUnit();
  var versionAttribute := new CodeTypeReference(typeOf(AssemblyVersionAttribute));
  var declaration: CodeAttributeDeclaration := new CodeAttributeDeclaration(versionAttribute, new CodeAttributeArgument(new CodePrimitiveExpression("1.0.2.42")));

  compileUnit.AssemblyCustomAttributes.Add(declaration);
  var provider := CodeDomProvider.CreateProvider("Oxygene");

  var writer: StringWriter := new StringWriter();
  provider.GenerateCodeFromCompileUnit(compileUnit, writer, new CodeGeneratorOptions());
  Console.WriteLine(writer.ToString());
end;

end.

But it seems like the assembly attribute is not generated. I realized then that
provider.Supports(GeneratorSupport.Resources)
is not set.

So, what is your recommendation to automatically build attribute resources? I assume, you need to do something similar when you generate the property file AssemblyInfo.pas

Just realized, in contrary to C#, Oxygene needs the namespace in the AssemblyInfo.pas.
When added the namespace:

compileUnit.Namespaces.Add( new CodeNamespace("MyNamespace") );

GenerateCodeFromCompileUnit will actually produce the expected attribute.

Sorry, still one problem I have overseen: the attribute is added before the interface and uses section instead of after. Any ideas / hints?

Also, extra

{$HIDE H7}
{$HIDE W1}
{$HIDE W27}
{$HIDE H11}

get added. Why?

I played a bit more with generating the “AssemblyInfo.pas” file for the CodeDom Compilation and I had no luck in generating a file which works.

The code above produces the following item:

//------------------------------------------------------------------------------
// <autogenerated>
//     This Oxygene source code was generated by a tool.
//     Runtime Version: 4.0.30319.42000
//     Changes to this file may cause incorrect behavior and will be lost if
//     the code is regenerated.
// </autogenerated>
//------------------------------------------------------------------------------

{$HIDE H7}
{$HIDE W1}
{$HIDE W27}
{$HIDE H11}

namespace MyNamespace;

[assembly: System.Reflection.AssemblyVersionAttribute('1.0.2.42')]

interface

uses
    System.Reflection,
    System.Resources,
    System.Runtime.InteropServices;
    
implementation

end.

but this does not set the attribute!

  1. The Assembly attributes have to be after in the interface section!
  2. At least the namespace is not relevant :wink:

So, when I change the generated output to the following, then the pas file compiled together with this “AssemblyInfo.pas” will have the proper attributes set in the DLL:

//------------------------------------------------------------------------------
// <autogenerated>
//     This Oxygene source code was generated by a tool.
//     Runtime Version: 4.0.30319.42000
//     Changes to this file may cause incorrect behavior and will be lost if
//     the code is regenerated.
// </autogenerated>
//------------------------------------------------------------------------------

{$HIDE H7}
{$HIDE W1}
{$HIDE W27}
{$HIDE H11}

namespace MyNameSpace;

interface

uses
    System.Reflection,
    System.Resources,
    System.Runtime.InteropServices;

    [assembly: AssemblyVersionAttribute('1.0.2.42')]

implementation

end.

So, I have no clue, how to bring GenerateCodeFromCompileUnit from the Oxygene Code Provider to produce a proper file containing Assembly Attributes.

And hint / idea is welcome.
