v0.4.0

✨ What's New

🏗️ Architecture Refactoring

• Modular Design: Refactored monolithic codebase into clean, maintainable modules

  • Reduced init.lua from 984 lines to 514 lines (-48%)
  • Extracted specialized engine components for better separation of concerns
  • Improved testability and code organization

• New Engine Modules:

  • engine/preview_manager.lua - Preview generation with intelligent caching
  • engine/replacement_engine.lua - Replacement execution with parallel support
  • engine/event_handlers.lua - Centralized keyboard event handling

⚡ Performance Improvements

Preview Generation: 33x Faster

• Before: 50 matches rendered in ~500ms
• After: 50 matches render in ~15ms
• Cache hits: <1ms (500x+ faster for repeated views)

How?

• Batch replacement: processes entire file in one shell call instead of per-line calls
• Intelligent caching: repeated previews are nearly instant
• Automatic cache invalidation on input changes

Parallel Replacement Execution: 3-5x Faster

• Before: 100 files completed in ~10s
• After: 100 files complete in ~2-3s

Features:

• Concurrent file processing using plenary.job
• Configurable concurrency (default: 20 files)
• Real-time progress notifications for large operations (>10 files)
• Smart backup strategy with atomic operations
• Full data integrity with error recovery

🐛 Bug Fixes

Keybinding Fix: <C-i> → <C-t>

Fixed case sensitivity toggle not working due to terminal key code collision:

• Issue: <C-i> and <Tab> send identical ASCII code (0x09) in terminals
• Solution: Changed to <C-t> (mnemonic: Toggle)
• Affected: Case sensitivity toggle in Search and Flags fields
• Impact: Toggle functionality now works correctly in all terminal environments

🧪 Testing

• Added integration tests for refactored modules
• Added performance benchmarks
• Added smoke tests for module loading

📊 Performance Comparison

Operation	Before	After	Speedup
Preview (50 matches)	~500ms	~15ms	33x
Preview (cached)	~500ms	<1ms	500x+
Replace 100 files	~10s	~2-3s	3-5x

🔧 Breaking Changes

⚠️ Keybinding Change: Case sensitivity toggle changed from <C-i> to <C-t>

If you have custom keybindings that rely on <C-i>, please update them to <C-t>.

v0.3.0

✨ What's New

Realtime Search

• No Enter required - Search triggers automatically as you type
• Debounced - 300ms delay to prevent excessive searches
• Match count - Shows [42] in Search title bar

Case Sensitivity Controls

• <C-i> in Search field - Toggle search pattern case
• <C-i> in Flags field - Toggle glob filter case

Regex Mode (Default)

• Regex patterns work out of the box
• Capture groups supported: $1, $2
• Example: print\(([^)]+)\) → logger.info($1)

Visual Selection Pre-fill

• Select text in visual mode, press <leader>sr
• Search field auto-fills with selection

🔧 Configuration

require("search-replace").setup({
  realtime = {
    enabled = true,
    debounce_ms = 300,
    min_chars = 2,
  },
})

v0.2.0

✨ What's New

Browse Mode

• Press o in Results to enter Browse Mode
• Navigate with n/N to jump between matches (just like Vim's search!)
• See full context - Review each match in its surrounding code
• Smart position tracking - Title bar shows Browse [3/8] - filename:42
• Auto-exit on Tab - Clean state management when switching focus

Why use Browse Mode?

• 👀 Review before replace - See matches in full context before making changes
• 🎯 Quick navigation - Jump through all occurrences with familiar n/N keys
• ✅ Better decisions - Choose exactly which files need replacement

🎹 Keybindings

In Results:

• o - Enter Browse Mode

In Browse Mode:

• n - Next match
• N - Previous match
• q - Exit Browse Mode
• Tab / Shift-Tab - Switch focus (auto-exits Browse Mode)

🐛 Bug Fixes

• Fixed border buffer validation errors
• Fixed "Buffer is not 'modifiable'" errors during focus switching
• Fixed state conflicts when switching between different files
• Simplified Results title bar for better visibility

🛠️ Technical Improvements

• Added lua/search-replace/core/browse.lua module (370+ lines)
• Implemented namespace-based highlighting (no conflicts with user's / search)
• Added buffer-local keymaps with automatic cleanup
• Improved defensive programming for robust state management

v0.1.1

Fixed

• Fixed keymap not working with lazy.nvim default configuration
• Fixed Enter key closing the dialog in Results window

Documentation

• Added detailed lazy.nvim installation examples (lazy=false and keys spec)
• Updated Vim help documentation
• Added Browse Mode design document for future v0.2.0

Installation

See README for updated installation instructions.
