v0.2.0

v0.2.0

New Features

• Process function — map .env variables directly into a struct using struct tags (envconfig, split_words, required, default, ignored). Supports string, int, uint, float, and bool field types.
• Optional filepath on LoadEnv and Process — both functions now accept an optional filepath argument. When omitted, .env is loaded by default, removing the need to pass nil or a pointer.

Breaking Changes

• LoadEnv signature changed: LoadEnv(filepath *string, verbose bool) → LoadEnv(filepath ...string)
• Process signature changed: Process(s any, filepath *string) → Process(s any, filepath ...string)
• The verbose parameter has been removed from LoadEnv

Performance Improvements

• Parallel env loading for files with 50+ variables — chunks are distributed across workers sized to available CPUs
• Memory improvements to env file parsing (pre-allocated slices, zero-copy byte scanning)

Bug Fixes

• Duplicate key handling: last occurrence now consistently wins
• Fixed concurrency issues related to env file size thresholds

Other

• Added Makefile with test and build targets
• Added CI via GitHub Actions
• go fix applied across codebase
• Updated README with full API reference and struct tag documentation

Migration: Replace goenv.LoadEnv(&file, false) with goenv.LoadEnv(file), and goenv.Process(&cfg, nil) with goenv.Process(&cfg).
