## [1.0.12] - 2025-02-05
### 🐛 Critical Bug Fixes
#### Wildcard Pattern Matching in Ignore Files
- **Fixed:** Patterns from ignore files (`.gitignore`, `.pt`, etc.) were not being matched correctly
- **Issue:** `*.exe` in `.gitignore` was not excluding `tree2.exe` because it was doing exact string match instead of wildcard matching
- **Solution:** Updated `should_exclude()` to properly handle wildcard patterns (`*` and `?`) from ignore files
- **Impact:** All wildcard patterns in ignore files now work correctly
**Before (BROKEN):**
```bash
# .gitignore contains: *.exe
tree2
# Output: tree2.exe still shows (WRONG)
```
**After (FIXED):**
```bash
# .gitignore contains: *.exe
tree2
# Output: tree2.exe is excluded (CORRECT)
```
#### Tree Connector Logic
- **Fixed:** Tree connectors (`├──` vs `└──`) were incorrect when files were excluded
- **Issue:** When entries were skipped due to exclusion, the connector calculation used the wrong index
- **Solution:** Filter entries first, then calculate connectors based on filtered list
- **Impact:** Tree structure now displays correctly with proper connectors
### ✨ New Features
#### Default System Folder Exclusion
- **Added:** System folders are now hidden by default
- **Hidden by default:** `.git`, `.svn`, `.hg`, `.bzr`, `_darcs`, `CVS`, `.DS_Store`, `Thumbs.db`, `desktop.ini`
- **New flag:** `-a, --all` to show these folders when needed
- **Rationale:** Most users don't want to see version control or system folders in their tree output
**Usage:**
```bash
tree2 # Hides .git and other system folders
tree2 -a # Shows everything including .git
tree2 --all # Same as above
```
### 📚 Documentation
- Added TROUBLESHOOTING.md with detailed debugging guide
- Updated README with wildcard pattern explanation
- Added default exclusions documentation
## [1.0.10] - 2025-02-05
### 🎉 Major Features Added
#### Multiple Ignore Files Support
- Added automatic support for all common ignore files:
- `.gitignore`
- `.dockerignore`
- `.npmignore`
- `.eslintignore`
- `.prettierignore`
- `.hgignore`
- `.terraformignore`
- `.helmignore`
- `.gcloudignore`
- `.cfignore`
- `.slugignore`
- `.pt` (default custom ignore file)
#### Selective Ignore File Usage
- Added `-i` / `--ignore-file` flag to specify which ignore files to use
- By default, all ignore files are loaded
- Users can now choose specific ignore files: `tree2 -i .gitignore .dockerignore`
#### Exception Patterns
- Added `-e` / `--exception` flag to exclude patterns from being ignored
- Supports three pattern types:
1. **Wildcard patterns**: `*.log`, `test_*`, `*_backup.*`
2. **Exact match**: `node_modules`, `.env`
3. **Regex patterns**: `regex:.*\d+$`, `regex:^test.*\.rs$`
#### Pattern Matching Implementation
- Implemented custom wildcard matcher for `*` and `?` patterns
- Integrated regex support with `regex:` prefix
- Smart pattern detection (auto-detects wildcards vs exact match)
### 🔧 Technical Improvements
- Added `Pattern` enum for flexible pattern matching
- Implemented `wildcard_match` function with recursive matching
- Enhanced `should_exclude` function to support exception patterns
- Added `load_all_ignore_files` function for multi-file loading
- Improved error handling for invalid regex patterns
### 📚 Documentation
- Comprehensive README with usage examples
- Added pattern matching examples
- Documented all command-line options
- Created example `.pt` file
- Added CHANGELOG
### 🐛 Bug Fixes
- Fixed issue where entries would be excluded even with exception patterns
- Improved pattern matching accuracy

## Migration Guide from 1.x to 2.0
### Breaking Changes
None - all 1.x functionality is preserved
### New Usage Patterns
#### Before (1.x):
```bash
tree2 # Only respects .gitignore
tree2 --exclude target # Manual exclusion
```
#### After (2.0):
```bash
tree2 # Respects ALL ignore files + .pt
tree2 -i .gitignore # Only use .gitignore
tree2 -e "*.log" # Keep .log files even if ignored
tree2 -i .gitignore -e "test_*" # Combine both features
```
### Recommended Workflow
1. Create a `.pt` file in your project root for project-specific ignores
2. Let tree2 automatically use all ignore files
3. Use `-e` to add exceptions when needed
4. Use `-i` to limit to specific ignore files if you want more control
Example `.pt` file:
```
# Project-specific ignores
*.tmp
.cache/
local_config.json
```
Then simply run:
```bash
tree2 # Uses .gitignore, .dockerignore, .pt, etc.
tree2 -e "*.tmp" # Keep .tmp files this time
```
