# Implementation Summary: v1.3 & v1.4
## Overview
Completed v1.3 (Tree View & Filtering) and v1.4 (Output Customization) features in a single development cycle.
**Current Version**: 1.3.0
**Next Version**: 1.4.0 (all features ready, version will be updated on next commit)
---
## ✅ v1.3 – Tree View & Filtering
### Tree View
- **Flag**: `--tree`
- **Features**:
- Recursive directory listing
- Includes all subdirectories and files
- Works with depth limiting
**Example**:
```bash
bestls --tree --depth 2
```
### Depth Control
- **Flag**: `--depth <N>`
- **Features**:
- Limits recursion depth
- Only applies with `--tree`
- Useful for large directory trees
**Example**:
```bash
bestls --tree --depth 3
```
### Extension Filtering
- **Flag**: `--filter-ext <EXT>`
- **Features**:
- Filter by file extension
- Comma-separated extensions supported
- Case-insensitive matching
**Examples**:
```bash
bestls --filter-ext rs # Only .rs files
bestls --filter-ext rs,md,toml # Multiple extensions
bestls -p src --filter-ext rs --compact # With other options
```
### Name Pattern Filtering
- **Flag**: `--filter-name <PATTERN>`
- **Features**:
- Glob-style pattern matching
- Supports `*` wildcards
- Examples: `*.txt`, `test_*`, `*_test.rs`
**Examples**:
```bash
bestls --filter-name "*.rs"
bestls --filter-name "test_*"
bestls --filter-name "*_config*"
```
### Size-Based Filtering
- **Flags**: `--min-size <SIZE>`, `--max-size <SIZE>`
- **Features**:
- Human-readable size units: B, KB, MB, GB, TB
- Supports decimal values (e.g., 1.5MB)
- Can be combined for range filtering
**Examples**:
```bash
bestls --min-size 1KB # Files >= 1KB
bestls --max-size 10MB # Files <= 10MB
bestls --min-size 100B --max-size 1MB # Files between 100B and 1MB
```
### Test Results
All filters working correctly:
```bash
$ bestls -p src --filter-ext rs --compact
cli.rs
fsops.rs
main.rs
table.rs
$ bestls -p src --min-size 10KB --compact
cli.rs
fsops.rs
table.rs
$ bestls -p src --filter-name "*.rs" --compact
cli.rs
fsops.rs
main.rs
table.rs
```

## ✅ v1.4 – Output Customization
### Compact Mode
- **Flag**: `--compact`
- **Features**:
- Single-column output (like `ls -1`)
- Minimal, clean presentation
- No table formatting
**Example**:
```bash
bestls --compact
```
### Column Customization
- **Flag**: `--columns <COLS>`
- **Features**:
- Specify visible columns
- Comma-separated list
- Available columns: name, type, size, date, permissions, owner, group
**Example**:
```bash
bestls --columns name,size,date
```
### Output to File
- **Flag**: `--out <FILE>`
- **Features**:
- Export results to file
- Works with JSON and text formats
- Useful for scripting
**Examples**:
```bash
bestls --json --out results.json
bestls --format json-pretty --out files.json
bestls --compact --out file_list.txt
```
### Format Override
- **Flag**: `--format <FORMAT>`
- **Values**: `table` (default), `json`, `json-pretty`
- **Features**:
- Explicit format selection
- Replaces legacy `--json` and `--json-pretty` flags
- Backward compatible
**Examples**:
```bash
bestls --format json
bestls --format json-pretty
bestls --format table (default)
```
### Color Control
- **Flag**: `--no-color`
- **Features**:
- Disable all colored output
- Useful for piping, logs, CI/CD
- Table still formatted, just no colors
**Example**:
```bash
bestls --no-color
```
### Backward Compatibility
Legacy flags still work:
```bash
bestls --json # Still works (same as --format json)
bestls --json-pretty # Still works (same as --format json-pretty)
```
### Test Results
All customization features working:
```bash
$ bestls --compact
Cargo.lock
Cargo.toml
LICENSE
...
$ ./target/release/bestls --out /tmp/test.json --format json
$ cat /tmp/test.json
[{"name":"CHANGELOG.md",...},...]
$ bestls --no-color

## 🔧 Implementation Details
### Code Structure
#### cli.rs
- Added `OutputFormat` enum (Table, Json, JsonPretty)
- Extended `Cli` struct with new flags:
- tree, depth, filter-ext, filter-name, min-size, max-size
- compact, columns, out, format, no-color
#### fsops.rs
- New functions:
- `parse_size()` - Parse human-readable sizes
- `matches_extension()` - Extension filtering
- `matches_pattern()` - Glob-style pattern matching
- `get_files_recursive()` - Recursive directory traversal
- `collect_files_recursive()` - Helper for recursion
#### main.rs
- Updated main() to:
- Choose between flat and recursive listing
- Apply all filters in sequence
- Support new format/output options
#### table.rs
- Enhanced print_table() signature:
- columns: Option<String>
- compact: bool
- use_color: bool
- Added parse_columns() helper

## 💡 Key Design Decisions
1. **Filter Application Order**:
- Extension → Name Pattern → Size Range
- All filters must pass (AND logic)
2. **Size Parsing**:
- Supports multiple units (B, KB, MB, GB, TB)
- Handles decimal input (e.g., 1.5MB)
- Case-insensitive unit matching
3. **Pattern Matching**:
- Simple glob with `*` wildcard support
- No regex complexity initially
- Can be enhanced later with full glob support
4. **Recursion Strategy**:
- Depth measured from starting path
- Depth 0 = start directory only
- Unlimited depth if --depth not specified
5. **Version Policy**:
- Manual version control (no auto-bumping)
- Prevents CI/development conflicts
- Clear release workflow documentation
