Custom Translation Logger
Build a custom logger plugin for an internationalization system that tracks translation lookups and missing keys for debugging purposes.
Requirements
Create a translation system that:
- Implements a custom logger plugin that captures all translation events
- Registers the custom logger with the i18n framework
- Tracks successful translation lookups and missing translation keys
- Provides methods to retrieve logged events for debugging
The logger should maintain separate lists for successful lookups and missing keys, allowing developers to identify translation gaps during development.
Test Cases
- Successfully logs a translation lookup when a key is found @test
- Records missing key events when translations are not found @test
- Allows retrieval of all logged events @test
- Works with multiple translation namespaces @test
