main executable is marked as a weed

[hanjoosten]

After running weeder on my project (Ampersand), it warns that the main executable is redundant. I firmly believe it is not 😁

This is the output:

PS C:\Users\hjo20125\Git\Ampersand> weeder . --build

This project uses a custom build-type. could that have anything to do with this?

This build was from the developement branch, commit 3b328c6f5e2ca4f33ad94e23a232a6faf2c9b103

Thanks, I can reproduce - will have an explore later tonight.

The issue is that you are using Windows, where the ampersand (due to the name of the project) and Ampersand (due to the root module) directories clash, so their contents are merged, and the equality check I was doing for filename was insufficient. I've just pushed a patch to give a platform-specific equality which does the right thing, and on your project, I now see no weeds.

I've also released weeder 0.1.11 with the fix included.

Thanx! works as a charm! I like the way you solved this. You are a great Haskeller!
