How do I view the hierarchy of which Unit USES another? (Delphi)

Question

There is a large project, and I need to see the hierarchy of Units which each file references in it's USES clause.

ex.

                                Project Source (program.dpk)

        HelperUnit                  Forms                ThirdPartyUnit

MyUtils MyConsts MyDownload                         TPShellShock  TPWhatever 

How can I see this dependency tree of sorts? I remember there being some feature like this in one of the newer Delphi versions, but I don't remember what it was called. It may have been a plugin.

Any hints on how to do this would be great. I started writing my own program to do it but I've already wasted like 3 hours and am still working on the parser for pas files.

Answer 1

I don't know a IDE integrated tool to do what you want, but you shall take a look at Unit Dependency Analyzer, from ModelMaker. The tool is free of charge.

Answer 2

There also is a unit dependancy analyzer built inside of GExperts. Look for the option labled "Project Dependencies". This does work from an expert within Delphi against the currently loaded project.

Answer 3

You've got such graphs created in an automated manner by our Open Source documentation tool, called SynProject.

It uses internal a fork of PasDoc to parse the interface part of your project units, then extract the comments to get detailed info about each class/method/function/unit. There are both unit dependencies diagrams and class hierarchy diagrams created from this data.

Then this information is merged into a whole technical documentation process, starting from Requirements, then Architecture, then Design, then Validation Plan, then Testing, then Release.

Answer 4

Icarus is another tool to analyzing your "uses" dependencies; it has a great feature that lists units that don't need to be in your uses clauses.

It's free.
