-## Implementation Priority
-
-### High Priority (Common Use Cases)
-1. ✅ String joining and splitting methods - Completed
-2. ✅ String validation methods (isBlank, isNotBlank, etc.) - Completed
-3. ✅ String manipulation methods (capitalize, reverse, etc.) - Completed
-4. ✅ Case conversion methods (camelCase, snakeCase, kebabCase, pascalCase,
titleCase) - Completed
-5. ✅ String cleaning and sanitization methods - Completed
-
-### Medium Priority (Useful Utilities)
-1. ✅ String searching and matching methods - Completed
-2. ✅ String formatting and templates - Completed
-3. ✅ String comparison and sorting methods - Completed
-4. ✅ String generation and random methods - Completed
-5. ✅ String parsing and extraction methods - Completed
-
-### Low Priority (Specialized Features)
-1. ✅ String transformation methods - Completed
-2. ✅ String validation patterns - Completed
-3. ✅ String metrics and analysis - Completed
-4. String conversion utilities
-5. Performance and memory utilities
-
-## Notes
-
-- All methods should follow the existing naming conventions and patterns
-- Methods should be null-safe where appropriate
-- Consider adding overloaded versions for common use cases
-- Include comprehensive Javadoc documentation
-- Add unit tests for all new methods
-- Consider performance implications for frequently used methods
-- Some methods might be better suited for separate utility classes (e.g.,
`RegexUtils`, `ValidationUtils`)
-
-## Existing Methods to Consider Enhancing
-
-- ✅ `format(String pattern, Object...args)` - Could be enhanced with more
formatting options
-- `parseNumber(String s, Class<? extends Number> type)` - Could add more
number types
-- `getDuration(String s)` - Could support more duration formats
-- `replaceVars(String s, Map<String,Object> m)` - Could add more variable
syntax options
-
-## Methods to Review/Deprecate
-
-- ✅ `stringifyDeep(Object o)` - **COMPLETED**: Replaced with `readable()` and
deprecated.
- - ✅ Replaced usage in `FluentObjectAssertion.equals()` (line 566) with
`readable()`
- - ✅ Previously used in `AssertionPredicate.VALUE` but has been replaced with
`readable()`
- - ✅ Method has been deprecated with `@Deprecated` annotation and Javadoc
updated to recommend using `readable()` instead
- - ✅ Differences in behavior:
- - `stringifyDeep()` uses `Arrays.toString()`/`Arrays.deepToString()` for
arrays (adds spaces: `[a, b, c]`)
- - `readable()` uses `Collectors.joining(",")` for collections/arrays (no
spaces: `[a,b,c]`)
- - `readable()` also handles byte arrays as hex (`0102`) vs
`stringifyDeep()` which uses `[1, 2]`
- - ✅ All usages have been updated and the method is now deprecated
