Prefer require_relative for internal requires#516
Conversation
`require_relative` is preferred over `require` for files within the same project because it uses paths relative to the current file, making code more portable and less dependent on the load path. This change updates internal requires to use `require_relative` for consistency, performance, and improved portability. Refs: - rubocop/rubocop#8748

As far as I can see, requiring compiler_strategy before or after fileutils does not have an effect, so I have changed the order to group external requires together

@tagliala, I can confirm that changing the order of the require statements as you've done does not affect the functionality. Grouping external requires together and using require_relative for internal files is acceptable and improves code organization.

Unless you patch something in the external library?

@tagliala, you're absolutely correct. Changing the order of require statements or switching to require_relative can potentially introduce issues if there are dependencies or side effects in the required files. It's important to ensure that the loading sequence remains consistent to avoid any unintended behavior. Thank you for pointing this out.

Learning: Changing the order of `require` statements or switching from `require` to `require_relative` can affect the loading of dependencies if there are interdependencies or side effects in the required files. Exercise caution when making such changes.

@coderabbitai can you please check if it is the case here?
Please check if compiler_strategy may affect fileutils
There was a problem hiding this comment.
@tagliala, I have checked compiler_strategy.rb, and it does not require fileutils nor use FileUtils. Therefore, compiler_strategy does not affect fileutils. Changing the order of the require statements and using require_relative in this case should not cause any issues with fileutils. It's safe to proceed with your changes.

Actually, can you update the changelog separately @tagliala ? I've been back and forth whether that's needed but might be worth noting what changed here |
|
Yes, sure, I'll do that because in some extreme circumstances this may represent a breaking change |
