Having consistently formatted source code makes life so much easier.
At Prestwood, we are often asked to enhance, update, and maintain Delphi applications created by somebody else. Some of it is well formated; lots of it is just horrible. Before I even start trying to understand the existing code, I let DelForEx have a run at it. And, man, does it ever make a difference.
But it's not just handy for cleaning up somebody else's code. Often, while working on my own code, I'll rearrange blocks of code by cutting and pasting. Often the indentation is way off. DelForEx fixes it pronto.
DelForEx is a free plug-in for the Delphi IDE. Highly recommended. Combined with GExperts, it turns your IDE into a real powerhouse.
