Refactor: Improve error handling, update dependencies, and refactor config (#14)
* Refactor: Improve error handling, update dependencies, and refactor config This commit introduces several improvements to the adr tool: 1. **Error Handling**: I replaced all `panic()` calls with proper error returns, particularly in the `helpers.go` module. Errors are now propagated up and handled gracefully by the command actions in `commands.go`, providing clearer, user-friendly messages. 2. **Update Deprecated `ioutil`**: I replaced all instances of the deprecated `io/ioutil` package with equivalent functions from the `os` and `io` packages (e.g., `os.ReadFile`, `os.WriteFile`). 3. **Configuration Management**: * I refactored global path variables in `helpers.go` into a `PathConfig` struct, which is initialized at startup. This centralizes path management and reduces global state. * I added a `GetDefaultBaseFolder()` getter in `helpers.go` and updated `commands.go` to use it, ensuring consumers of these paths use the new centralized configuration. 4. **Testing**: * I updated existing tests in `helpers_test.go` and `main_test.go` to align with the new error handling mechanisms (expecting returned errors instead of panics) and the `PathConfig` refactoring. * I added new tests to cover `NewPathConfig`, `GetDefaultBaseFolder`, and the scenario of running the `new` command before `init`. * I improved test setup and teardown for better isolation and cleanup, including the use of temporary directories for test-specific configurations. These changes enhance the robustness, maintainability, and testability of the application. * Refactor: Improve error handling, update dependencies, and refactor config This commit introduces several improvements to the adr tool: 1. **Error Handling**: I replaced all `panic()` calls with proper error returns, particularly in the `helpers.go` module.
