Delphi and Fitnesse/fit4delphi examples

delphifitnesse

Is there any opensource or example projects showing the use of fitnesse with delphi?

It's sad how hard it is to find resources and information for delphi… :-/

UPDATE:
Ok. I realize that my question was a little short. Searching SO and google was kind of obvious for me, so I didn't mention that I already did. So to clarify a little:
* I know about fit4delphi (thereof the use of fit4delphi both in the title and the taglist)
* I know fit4delphi is somewhat maintained (both from fit4delphi site and other SO-thread)
* I know the most basic examples from fitnesse is ported to delphi and comes with fit4delphi
* I know it is possible to use delphi together with fit/fitnesse (comes from the knowledge of fit4delphi and basic google search giving lots of results stating that it is possible)

What I want, is examples of use, not a google query showing that it is possible to use.
I want stories by people with experience from fit4delphi, not from people with experiences from basic google querying.

Doing a simple google on "fitnesse delphi" I came up with a few different results.

You might want to look at this for starters:

Fitnesse for Delphi 2006 / Delphi 2007 /Delphi 2009 - Stack Overflow

Or maybe you want to try the google query I used:

Google for "fitnesse delphi"

I don't know much about fitnesse but I didn't find it difficult to find information about it WRT Delphi.

Delphi – the Delphi Attributes Real World Examples

I must say it's not much clear to me what kind of example do you need. IMHO in http://docwiki.embarcadero.com/RADStudio/Rio/en/Overview_of_Attributes is everything you should need, perhaps providing that you have some basic knowledge of annotation and/or aspect programming resp.

An example depends on the way/purpose an author of particular SW used attributes for. You mentioned the ORM system: the typical usage here is to annotate member of the class representing DB entity with additional information necessary for DB operation in the backend of such framework. Let assume you have a DB entity having field COMPANY CHAR(32) NOT NULL and you want to represent it in Delphi class:

TSomeDBEntity = class(...)
  FCDS: TClientDataset;
  ...
  constructor Create;
  ... 
  [TCharColumn('COMPANY', 32, false)]
  property CompanyName: string read GetCompanyName write SetCompanyName;
end;

then you will define attribute TCharColumn with constructor

constructor TCharColumn.Create(const AFieldName:string; ALength:integer; ANullable:boolean);
begin
  inherited;
  FName := AFieldName;
  FLength := ALength;
  FNullable := ANullable;
end;

And usage of such annotation could look something like this:

FCDS := TClientDataset.Create(nil);
RttiContext := TRttiContext.Create;
try
  RttiType := RttiContext.GetType(self.ClassType);
  Props := RttiType.GetProperties;
  for Prop in Props do
    begin
      Attrs := Prop.GetAttributes;
      case Prop.PropertyType.TypeKind of
        tkUString:
          begin
            for Attr in Attrs do
              if Attr is TCharColumn then
              begin
                ColAttr := TCharColumn(Attr);
                FCDS.FieldDefs.Add(ColAttr.FName, ftString, ColAttr.FLength, not ColAttr.FNullable);
              end;
          end;
        else
          //... ;
      end;
    end;
finally
  RttiContext.Free;
end;

This piece of the program demonstrates, how to define fields in a dataset in run-time based on annotation in Delphi. We are limited little bit due lack of named parameters, hence working with parameter list is not flexible as should be e.g. like in Java (compare TMS Aurelius annotation set http://www.tmssoftware.com/site/manuals/aurelius_manual.pdf and http://www.techferry.com/articles/hibernate-jpa-annotations.html
