Delphi 7 : how to generate class hierarchy?

I am seeking to und开发者_运维问答erstand someone else's code in Delphi 7 (I suspect that newer version have this built in, but I don't want to spring > $1k for the newest version).

Are their any (preferably FOSS) tools which will help me generate a class hierarchy diagram?

Actually, the class browser in GExperts is ok. Maybe not as good as the accepted answer, but just one of a great collection of tools

You can use ESS-model from SourceForge.
If you Load and .PAS (also .DPR, .CLASS,...) with some classes this program generate a Class Diagram and some Documentation. It's free and you can access to code source.

AFAIK ModelMaker 6.2 was included with Delphi 7, it's a UML tool. You can import your source code in it and generate class diagrams etc, I really don't remember anymore all of it's features, but I do remember that ModelMaker is awesome tool and it's sure worth a look.

Update: Model Maker (now MMX) is now free for all supported Delphi IDEs

You can take a look at our SynProject tool.

Synopse SynProject is an open source application for code source versioning and automated documentation of Delphi projects.

There is a pascal source parser, which will create all classes hierarchy documentation.

And it's much more than a parser: you can write the whole Specifications/Architecture/Design/Test/Release documents list in an integrated manner.

There are some tutorials, screenshots and resulting documentation sample in the above link.

Peganza's Pascal Analyzer (not FOSS)

Doc-o-matic's documentation generator creates class hierarchies. They have a free express version you can try.
