Calculating stats for a packwere pack inside the app shows stats for the whole app unless I run it from outside the app

[oboxodo]

Using rails_stats v1.0.2

Given I have added gem "rails_stats" to my Gemfile and I have the following app's file structure (typical when using packs-rails):

my_rails_app/
├── app
│   ├── controllers
│   └── models
├── lib
└── packs
    ├── pack1
    │   ├── app
    │   │   ├── controllers
    │   │   └── models
    │   └── lib
    └── pack2
        ├── app
        │   ├── controllers
        │   └── models
        └── lib

If I run rake stats from inside my_rails_app, it correctly shows stats including files from the main app as well as each of my packwerk packs living in packs/*:

$rake stats
+----------------------+-------+-------+---------+---------+-----+-------+
| Name                 | Lines |   LOC | Classes | Methods | M/C | LOC/M |
+----------------------+-------+-------+---------+---------+-----+-------+
|...real output removed but it's correctly including all files           |
|  from . and from packs/*                                               |
+----------------------+-------+-------+---------+---------+-----+-------+
| Total                |  xxxx |  xxxx |    xxxx |    xxxx |  xx |    xx |
+----------------------+-------+-------+---------+---------+-----+-------+
  Code LOC: xxx     Test LOC: xxx     Code to Test Ratio: 1:x.x

Trying to get stats about a specific pack's files, from inside the app's root directory (my_rails_app), doesn't work as expected. The stats are still calculated for the whole app, but it includes the header stating the directory too:

$rake stats[packs/pack1]

Directory: /home/oboxodo/Code/my_rails_app

+----------------------+-------+-------+---------+---------+-----+-------+
| Name                 | Lines |   LOC | Classes | Methods | M/C | LOC/M |
+----------------------+-------+-------+---------+---------+-----+-------+
|    ...real output removed but it's the same output                     |
|    as running it for the whole app                                     |
+----------------------+-------+-------+---------+---------+-----+-------+
| Total                |  xxxx |  xxxx |    xxxx |    xxxx |  xx |    xx |
+----------------------+-------+-------+---------+---------+-----+-------+
  Code LOC: xxx     Test LOC: xxx     Code to Test Ratio: 1:x.x

Now, if I move outside the app's directory, to the parent, and I create a Rakefile with require "rails_stats", then this works as expected:

$for pack in my_rails_app/packs/*; do rake stats[$pack]; done

Directory: /home/oboxodo/Code/my_rails_app/packs/pack1

+----------------------+-------+-------+---------+---------+-----+-------+
| Name                 | Lines |   LOC | Classes | Methods | M/C | LOC/M |
+----------------------+-------+-------+---------+---------+-----+-------+
|...real output removed...                                               |
+----------------------+-------+-------+---------+---------+-----+-------+
| Total                |  xxxx |  xxxx |    xxxx |    xxxx |  xx |    xx |
+----------------------+-------+-------+---------+---------+-----+-------+
  Code LOC: xxx     Test LOC: xxx     Code to Test Ratio: 1:x.x

Directory: /home/oboxodo/Code/my_rails_app/packs/pack2

+----------------------+-------+-------+---------+---------+-----+-------+
| Name                 | Lines |   LOC | Classes | Methods | M/C | LOC/M |
+----------------------+-------+-------+---------+---------+-----+-------+
|...real output removed...                                               |
+----------------------+-------+-------+---------+---------+-----+-------+
| Total                |  xxxx |  xxxx |    xxxx |    xxxx |  xx |    xx |
+----------------------+-------+-------+---------+---------+-----+-------+
  Code LOC: xxx     Test LOC: xxx     Code to Test Ratio: 1:x.x

I hope I was able to express the problem 😅
