List of all uses clause items in the whole project

[Dinar 22]

You may also try to use Delphi Unit Dependency Scanner. View used units in "list" tab. This program, compiled from the sources, supporting export scanned results to csv file, where the first column will be the all units. I hope you know that csv file can be open with Microsoft Excel (WPS Spreadsheets, LibreOffice Calc, etc.), where columns can be filtered, that allow you to find unique cell contents in a column (just in case, although the exported list should be, in theory, already unique)

@PeterPanettone Isn't GExperts -> Project Dependencies what you are looking for?

The only shortcoming is that it does not list the indirect dependencies for the whole project, into which I am looking right now. If it's possible to be done easily, I will add that.

Done. I even improved performance of the indirect list by a factor of about 5 to 10 (I didn't do any exact timing on the original code, so I don't know. But it now takes less than 2 seconds for the GExperts project where before it took more than 10.)

 

Note to self: If the performance of some code is bad, check whether it stores and accesses data in the UI all the time. Remove this access and watch the performance skyrocket.

 

Another note to self: TListView is one of the worst performing controls out there. If you want to improve performance further, use a TStringList or maybe even better a virtual string list.

You can use TListView in a virtual mode then it is as fast as a VirtualStringTree.

 

OwnerData = True
OnData = ListView1Data

procedure TForm6.Button1Click(Sender: TObject);
begin
  ListView1.Items.Count := 100000000;
end;

procedure TForm1.ListView1Data(Sender: TObject; Item: TListItem);
begin
  Item.Caption := IntToStr(Item.Index);
end;

Was already used, that was the first thing I checked.

Thomas, I've built #2590. But I don't see where I can display and/or export a merged list of all used units in the whole project. The list created by "Export Used Units..." is the same as before.

 

BTW, is there somewhere a possibility to see the current version/release number in the IDE, because both the old and the new show the same version number:

That list already contained all used units, including those indirectly used.

 

And the list for the project (root node in the tree) contains all units of the project.

Thomas, you are right.

 

However, this is not a merged list without duplicates in the strict sense because in the following case ComCtrls is being listed twice:

 

uPDFViewer,ComCtrls

SkinDemoUtils,ComCtrls

 

So, the exported list is certainly useful. But for my purpose, I need to remove the duplicates.

Thomas, what do you mean by "contains all units of the project"? When I select the root node "GExpertsRS103.dproj" on the left side then only the GX_* project units are displayed in the "Unit Uses" tab on the right side:

 

 

... and no indirectly used units are displayed in this tab.

... and then you switch to the "indirect dependencies" tab and ... ?

OK, I get it.

 

But then, why I don't get indirect units in the same way if I select a directly used unit node in the left tree:

 

 

In this case, even the "Unit Uses" tab does not show any used units in "ToolsApi".pas, although it has a uses clause:

Possibly a bug

[dummzeuch 1386]

Not a bug.

 

ToolsApi.pas is not in the search path (only ToolsApi.dcu), so it isn't parsed. You can see that in the Unit Uses list of GX_About: There is no Location info for that unit because it cannot be found.

 

OK, that means that the list of indirect depencencies is not complete, because it does not contain units that are only in the uses list of units that are not in  the search path.

 

Hm, not sure I like that.

Still was a but. It didn't work for units in the project either.
