Release v0.1.2: Code quality improvements and linting fixes

greysquirr3l · greysquirr3l · commit b8ba01dbf756 · 2025-06-22T23:13:05.000-04:00
### Fixed
- Reduced cyclomatic complexity in key functions (DataTypeOf, DefaultValueOf, QuoteTo, FullDataTypeOf)
- Fixed all unchecked error returns from writer operations
- Resolved integer overflow concerns with proper bounds checking
- Applied consistent code formatting with gofumpt
- Addressed all golangci-lint issues (errcheck, gocritic, gosec, staticcheck)

### Changed
- Refactored DataTypeOf function into smaller helper methods for better maintainability
- Simplified QuoteTo function logic while maintaining functionality
- Enhanced error handling throughout codebase with proper return value checking
- Implemented type switch optimization for better performance
- Added nolint comments for embedded field usage following GORM patterns

### Technical Details
- Split complex functions into smaller, more manageable helper functions
- Added proper error handling for all writer operations with #nosec comments where appropriate
- Implemented type assertions and error checking best practices
- Reduced cyclomatic complexity from 22+ to under 10 for all functions
- All golangci-lint checks now pass with zero issues

-# GORM DuckDB Driver v0.1.0 🚀
-
-First public release of the DuckDB driver for GORM!
-
-## 🎯 What is this?
-A production-ready adapter that brings DuckDB's high-performance analytical capabilities to the GORM ecosystem. Perfect for data science, analytics, and high-throughput applications.
-
-## ✨ Features
-- **Complete GORM Integration**: All dialector and migrator interfaces implemented
-- **Auto-increment Support**: Uses DuckDB sequences for ID generation
-- **Type Safety**: Comprehensive Go ↔ DuckDB type mapping
-- **Connection Pooling**: Optimized connection handling with time conversion
-- **Schema Introspection**: Full table, column, index, and constraint discovery
-- **Test Coverage**: 100% test pass rate with comprehensive test suite
-
-## 🚀 Quick Start
-
-```go
-import (
-    "gorm.io/gorm"
-    "github.com/greysquirr3l/gorm-duckdb-driver"
-)
-
-db, err := gorm.Open(duckdb.Open("test.db"), &gorm.Config{})
-```
-
-## 📊 Perfect For
-
