depcheck's Issues

Export Graph Dot File

It would be great if there was an option in the graph command to simply export the Dot file rather than going through the whole process of generating the GraphViz image. That way the Dot file could be imported into other programs (such as OmniGraffle). It would also make the dependency graph editable.

Generating Graph for Watch.

Currently depcheck does not support graphing for Watch with error message
No derived data found. Please make sure the project was built.

I did some investigation and found out that this is because In the case of Watch, data are stored inside 'target_name Extension.build' (at least for my project).

I was able to analyze and graph by manually adding ' Extension' inside Finder module.

Dependencies doesn't take into account enum used inside other enum for it's associated value

enum ParentEnum {
    case Info(enumA: EnumA)
}

enum EnumA {
    case A
}

In this case EnumA is showing 0 dependency which is true, but would be nice if we could see if it's been used somewhere (like the case above)

Graph creation fails silently

Steps to reproduce:

Install depcheck via gem install depcheck
See all dependencies get installed properly
Run depcheck graph
depcheck graph fails silently

Expected Behavior:

Find the graph.png file on the file system

Notes:

Also tried by giving the gem executable, read and write permissions.
Analyze works but Graph doesn't.
I tried with different projects and schemes and it always failed silently on the graph creation

Assumptions:
Xcode version: 9.0.1
Using RVM

Output:

Hanoi julio$ depcheck analyze --project /Users/julio/Github/Hanoi/Hanoi.xcodeproj --scheme Hanoi
1. HanoiViewsTests - 7
2. HanoiTests - 6
3. ViewController - 0
4. AppDelegate - 0
Hanoi julio$ depcheck graph --project /Users/julio/Github/Hanoi/Hanoi.xcodeproj --scheme Hanoi
Hanoi julio$

Ability to list dependencies for the objects

Just having the number of dependencies is a very useful tool, but I would love an option to show what the dependencies are.

Dependency graph visualization

It would be nice to have a visual representation of the dependency graph (an image). You could use dotty and graphviz (http://www.graphviz.org) for that.

`depcheck version` fails with uninitialized constant error

$ depcheck version
/Users/ldiqual/.rbenv/versions/2.3.0/lib/ruby/gems/2.3.0/gems/depcheck-0.1.0/lib/depcheck/command/version_command.rb:4:in `execute': uninitialized constant Depcheck::VERSION (NameError)

Assorted duplicate items

Just wanted to report that I get duplicates, sometimes interspersed:

$ depcheck analyze --project TableFlip.xcodeproj
1. TableEventHandler - 18 
2. TableEventHandler - 18 
3. TableInteractionController - 16 
4. TableInteractionController - 16 
5. TableInteractionController - 16 
6. MarkdownTable - 14 
7. MarkdownTable - 14 
8. MarkdownTable - 14 
9. TableViewModel - 12 
10. DocumentStateContextAdapter - 12 
11. DocumentStateContextAdapter - 12 
12. DocumentStateContextAdapter - 12 
13. TableViewModel - 12 
14. AppActionContext - 10 
15. TableContextMenuController - 10 
16. ToolbarItems - 10 
17. TableContextMenuController - 10 
18. ToolbarItems - 10 
19. TableContextMenuController - 10 
20. AppActionContext - 10 
21. ToolbarItems - 10 
22. AppActionContext - 10

I also wonder where the 18 dependencies of the first item come from 🤔 Maybe the rather big Interface Builder file gets in the way?

`depcheck analyze` generates a lot of duplicates

Here's one example of an output on my production app:

1. TROverviewVC - 51
2. TROverviewVC - 51
3. TROverviewVC - 51
4. TROverviewVC - 50
5. SCInviteVC - 38
6. SCInviteVC - 38
7. SCInviteVC - 38
8. SCInviteVC - 38
9. TRItineraryCardVC - 36
10. TRItineraryCardVC - 36
11. TRItineraryCardVC - 36
12. TRItineraryCardVC - 36
13. TRScheduleVC - 36
14. DeveloperVC - 29
15. DeveloperVC - 29
16. DeveloperVC - 29
17. DeveloperVC - 29
18. STDrivingDocumentVC - 28
19. STDrivingDocumentVC - 28
20. STDrivingDocumentVC - 28
21. STDrivingDocumentVC - 28
22. AppDelegate - 27
23. AppDelegate - 27
24. AppDelegate - 27
25. AppDelegate - 27
26. OBCredentialsVC - 26
27. OBCredentialsVC - 26
...

Side question: how can TROverviewVC have both a count of 50 and 51?

Dependencies doesn't take into account classes used in Interface Builder

Ability to exclude pods or carthage dependency

First of all - cool tool! It gave me more insight into my project, so thanks for that!
Second, I would really like to see the ability to exclude certain folders like pods/carthage, because these tend to clutter the results.

Cheers,
