While maintaining full backward compatibility through command aliases, brlex3 represents a fundamental modernization of the codebase. + +### Added + +#### Core Architecture +- **Full expl3 implementation**: Complete rewrite using LaTeX3 programming conventions +- **Proper namespace management**: All internal functions use `brlex_` prefix following expl3 naming conventions +- **Type-safe programming**: Functions use proper argument specifiers (`:nn`, `:n`, `:N`, etc.) +- **Modular code organization**: Logical separation into modules (setup, options, structure, dispositivos, formatting, metadata, utilities) + +#### Enhanced Options System +- **Key-value options using l3keys**: Modern, extensible options interface +- **New option syntax**: Support for `font=calibri`, `article-bold=true`, `emphasis=bold` +- **Backward compatible**: All old-style options (`calibri`, `artbold`, etc.) still work +- **Better validation**: Options are validated with clear error messages + +#### Improved Message System +- **Centralized messages**: All warnings and errors defined in one place using `\msg_new:nnn` +- **Clearer error messages**: More helpful guidance for users +- **Consistent formatting**: Standardized message presentation +- **Localization ready**: Message system prepared for future translations + +#### Counter Management +- **Modern counter handling**: Using `\int_new:N` and related l3int functions +- **Hierarchical reset system**: Proper counter dependencies with explicit reset functions +- **Type-safe operations**: All counter operations use expl3 integer functions + +#### Text Processing +- **Language-aware text conversion**: Using `\text_uppercase:n` for proper case handling +- **Improved accent handling**: Better support for Brazilian Portuguese special characters +- **Robust text manipulation**: More reliable text processing for document structure elements + +#### Code Quality +- **Comprehensive inline documentation**: All functions documented following expl3 conventions +- **Better code organization**: Logical grouping of related functionality +- **Consistent coding style**: Following expl3 best practices throughout +- **Improved maintainability**: Clearer code structure for future development + +### Changed + +#### Breaking Changes (with compatibility layer) +- **Class name**: Now `brlex3` (old documents using `brlex2` continue to work) +- **Internal implementation**: Complete rewrite (but user-facing commands unchanged) +- **File structure**: New modular organization (transparent to users) + +#### Improvements +- **Performance**: Optimized counter and conditional operations using native expl3 +- **Robustness**: More reliable command execution with better error handling +- **Extensibility**: Easier to add new features thanks to modular design +- **Documentation**: Comprehensive inline code documentation + +#### Enhanced Commands +All existing commands maintain their original syntax while benefiting from improved internal implementation: +- `\artigo`, `\paragrafo`, `\inciso`, `\alinea`, `\itens`: More robust, better formatted +- `\parte`, `\livro`, `\titulo`, `\capitulo`, `\secao`, `\subsecao`: Improved TOC integration +- `\epigrafe`, `\ementa`, `\preambulo`: Better metadata handling +- `\metadata`: Enhanced PDF metadata generation + +#### Options Processing +- **indent**: Now using l3keys, more flexible +- **calibri**: Better detection and error messages for engine compatibility +- **artbold**: Cleaner implementation using boolean operations +- **usetitle**: More consistent application +- **useitalic**: Proper emphasis command redefinition + +### Fixed +- **Counter reset behavior**: More reliable hierarchical counter resets +- **Text case conversion**: Better handling of accented characters in uppercase conversion +- **Hanging indent**: More consistent application in indent mode +- **TOC entries**: Improved formatting and nesting in table of contents +- **Metadata handling**: More robust PDF metadata generation + +### Technical Details + +#### LaTeX3 Features Used +- **Variables**: `\bool_new:N`, `\tl_new:N`, `\int_new:N`, `\dim_new:N` +- **Conditionals**: `\bool_if:NTF`, `\int_compare:nNnTF`, `\tl_if_empty:nTF` +- **Text processing**: `\text_uppercase:n`, proper expansion control +- **Keys**: `\keys_define:nn` for modern option handling +- **Messages**: `\msg_new:nnn` for warning and error system +- **Document commands**: `\NewDocumentCommand` with argument specifiers + +#### Code Statistics +- **Lines of code**: ~600 (compared to ~390 in brlex2) +- **Documentation**: ~150 comment lines added +- **Functions**: 30+ properly namespaced expl3 functions +- **Modules**: 7 logical code sections +- **Variables**: 20+ typed variables (bool, tl, int, dim) + +#### Compatibility +- **Engines**: pdfLaTeX, XeLaTeX, LuaLaTeX (tested) +- **LaTeX version**: Requires LaTeX2e with expl3 support (TeX Live 2020+) +- **Package dependencies**: Same as brlex2 (iftex, fmtcount, geometry, hyperref) +- **Backward compatibility**: 100% via command aliases + +### Migration Guide + +#### For Simple Documents +No changes required!
