Moves all test files from the `tdd/` directory to their corresponding `pkg/` subdirectories. This aligns with standard Go project structure and simplifies the test coverage workflow.
- Moves `tdd/crypt/crypt_test.go` to `pkg/crypt/`
- Moves `tdd/enchantrix/enchantrix_test.go` to `pkg/enchantrix/`
- Moves `tdd/trix/trix_test.go` to `pkg/trix/`
- Simplifies the `Taskfile.yml` to use a standard `go test` command.
- Removes the now-obsolete `tdd/` directory.
- Adds generated coverage files to `.gitignore`.
This commit consolidates and enhances the tests for the `enchantrix` and `trix` packages, moving them into the `tdd/` directory to improve test coverage and organization.
- Consolidates existing tests from `pkg/enchantrix/` and `pkg/trix/` into new, more comprehensive test suites in `tdd/enchantrix/` and `tdd/trix/` respectively.
- Expands the test suites to include more "Bad" and "Ugly" scenarios.
- Deletes the original test files from `pkg/enchantrix/` and `pkg/trix/` to avoid redundancy.
- Organizes the `tdd/` directory with subdirectories for each package to prevent Go package conflicts.
This commit introduces a new `enchantrix` package that provides a flexible and powerful way to transform data using a "Sigil" interface. The package includes implementations for various encoding types (hex, base64, gzip, json) and a comprehensive set of cryptographic hash functions.
The `trix` package has been refactored to use the new `enchantrix` package, and its API has been simplified to use string identifiers for Sigils, making it easier to use and decoupling it from the implementation details of the `enchantrix` package.
All new functionality is fully tested, and the existing tests have been updated to reflect the API changes.
This commit enhances the Trix container with two new features for improved data integrity and flexibility:
1. **Configurable Checksums:**
- The `Trix` struct now has a `ChecksumAlgo` field to specify a hash algorithm.
- If set, `Encode` computes a checksum of the payload and adds it to the header.
- `Decode` verifies this checksum, returning an error if it doesn't match, ensuring data integrity during transit.
2. **Asymmetrical Sigils:**
- The `Sigils` field has been replaced with `InSigils` and `OutSigils` to support different transformation chains for packing and unpacking.
- If `OutSigils` is not set, `Unpack` defaults to using the `InSigils` chain to maintain the previous symmetrical behavior.
These features make the `Trix` container a more robust and self-verifying format for internal data transfer.
