Question 1

How do I install Generics.Collections in my FreePascal project?

Accepted Answer

Typically, you need to download the source files and include them in your project path or use FPC's package manager. Check the GitHub repository for specific instructions, as the README is minimal.

Question 2

Is Generics.Collections stable enough for production use?

Accepted Answer

It depends on your risk tolerance—the library has known critical bugs listed in the README. For critical applications, test thoroughly or consider alternatives until bugs are resolved.

Question 3

Generics.Collections vs Delphi's built-in TList: which should I use?

Accepted Answer

If you're using FreePascal, Generics.Collections is a good choice for type safety. For Delphi, stick with its native generic collections, which are more mature and better integrated.

Question 4

How to iterate over a TList in Generics.Collections?

Accepted Answer

Use a for-in loop or traditional index-based iteration, similar to other Pascal collections. Refer to the source code or community examples since documentation is sparse.

Question 5

Can Generics.Collections handle multi-threaded applications?

Accepted Answer

The library doesn't explicitly mention thread safety, so you likely need to implement your own synchronization mechanisms, such as locks, to prevent race conditions.

Question 6

What's the performance impact compared to traditional Pascal arrays?

Accepted Answer

Generics.Collections offers better type safety but may have slight overhead due to generics. For most applications, it's negligible, but benchmark for critical paths.
