A simple debug visualizer for delphi 2010

Question

Hello,

I gather some experience with the trial version of delphi 2010. I am looking for a simple debug visualizer, because the sample debug visualizers are not part of the trail. I do a lot with the new rtti type TValue and TValue.ToString can't be call from the debugger (results in an exception), so my idea is to write a debug visualizer for it. The format shoul look like

(<data-type)<ToString-value>

examples

(integer)5
(string)'Hello World'
(Array<String>)['a', 'list', 'of', 'items']

With a simple demo for a debug-value-replacer (I think this was the name :-) ) I can start.

Answer 1

I noticed on Torry that Mitov Software has a (free) sample debug visualizer with source. It may help you even though it does not do exactly what you need. I have not downloaded it myself.

Answer 2

Delphi 2010 ships with an example of both types of visualizers, including source. The StdStringVisualizer is a Value Replacer type visualizers. It's source in a default installation of RAD Studio 2010 is in C:\Program Files\Embarcadero\RAD Studio\7.0\source\Win32\Visualizers\StdStringVisualizer.pas

Unfortunately, since you're using the trial, you won't have this file, and the license prohibits anyone from providing it to you. I guess you'll have to wait to write your debugger visualizer until you actually buy a license. :-)
