refactor: updates Package Structure, Add Interfaces, and Enhance Testing#29
Conversation
Removed main_test.go as its functionality is now integrated into more specific test files.
Removed main.go file to migrate functionality to the more appropriately named cli/main.go.
Define a configuration struct for command line options to manage and parse command line arguments effectively.
Introduce interfaces for content reading and clipboard writing to enhance flexibility and testability.
Refactor command line argument handling into a dedicated CLI package for improved organization and clarity.
- Modify the Run function to accept a ClipboardWriter as a parameter instead of creating a DefaultClipboardWriter directly. This would enable easier mocking of the clipboard for testing.
This commit introduces a new `tests/clipper_test.go` file, which includes comprehensive unit tests for the clipper package. The tests cover various components including: - FileContentReader: Reads content from a file. - StdinContentReader: Reads content from standard input. - DefaultClipboardWriter: Writes content to the clipboard. - ParseContent: Parses content from multiple sources, including direct text, files, and invalid inputs. Additionally, the tests use helper functions for creating temporary files and replacing stdin, improving readability and maintainability.

Skipping clipboard test in short mode. Helps avoid errors when on CI environments.
…and exiting - Refactored the `Run` function to return a `string` (representing the success message or version information) and an `error`. - This change allows the caller of `Run` to handle the output and errors gracefully, rather than relying on `Run` to print messages and exit directly. - Updated the error handling to use `fmt.Errorf` with error wrapping (%w) for better context. - This improvement enhances the flexibility and testability of the `clipper` tool.
… values - Modified the `main` function to call `clipper.Run` and handle both the returned message and error. - Prints the success message if no error occurred, or an error message if an error was encountered. - Exits with a status code of 0 for success or 1 for errors. - This change ensures that the `main` function gracefully handles the output and errors generated by the `Run` function.

- Introduced a new function `GetReaders` in `clipper.go` to handle the logic of creating `ContentReader` instances based on command-line arguments. - This refactoring improves the readability and maintainability of the `Run` function by separating out a specific task. - The `Run` function now calls `GetReaders` to obtain the necessary readers, making its logic more focused and concise.
