Command Line Options

Usage: tree2 [OPTIONS] [PATH]

Arguments:
  [PATH]  Target directory [default: .]

Options:
  -e, --exclude <EXCLUDE>...   Exclude directories/files (exact match only)
  -c, --clipboard              Copy result to clipboard

Options Details

Important: Exact Match Exclusion

The -e flag uses exact match only. This means:

• -e .git will exclude only .git folder
• -e .git will NOT exclude .github folder
• Each exclusion must match the exact name

With Exclusions

# Exclude single pattern
tree2 -e target

# Exclude multiple patterns (space-separated)
tree2 -e target .git node_modules

# Exclude multiple patterns (multiple -e flags)
tree2 -e target -e .git -e node_modules

# With clipboard
tree2 -e target -e .git -c

Examples

# Typical Rust project directory
tree2 -e target -e .git

# Python project
tree2 -e __pycache__ -e .venv -e dist

# Node.js project
tree2 -e node_modules -e dist -e .next

# With clipboard for sharing
tree2 -e target -e node_modules -c

# Specific path with exclusions
tree2 /path/to/project -e target -e .git

Usage: tree2 [OPTIONS] [PATH]

Arguments: [PATH] [default: .]

Options: -e, --exclude [...] Exclude directories/files (exact match only) -c, --clipboard Copy result to clipboard -V, --version Print version information -h, --help Print help

## Output Example

📂 /home/user/project/ ├── 📁 src/ │ ├── 📄 main.rs (12.45 KB) │ └── 📄 lib.rs (0.00 B) ├── 📁 tests/ │ └── 📄 integration_test.rs (2.10 KB) ├── 📄 Cargo.toml (1.20 KB) ├── 📄 README.md (4.50 KB) └── 🔒 [Permission Denied]

### Clipboard Output

When using `-c` flag, the output copied to clipboard is **plain text without ANSI color codes**, making it perfect for:
- Pasting into documentation
- Sharing in emails or chat
- Including in Markdown files
- Code reviews and discussions

## Library Usage

Add to your `Cargo.toml`:

```toml
[dependencies]
tree2 = "0.1.0"

Basic Example

use tree2::TreeBuilder;

fn main() {
    let tree = TreeBuilder::new()
        .path(".")
        .excludes(vec!["target", ".git"])
        .build();
    
    tree.print();
}

Advanced Example

use tree2::{TreeBuilder, TreeConfig};

fn main() {
    let config = TreeConfig {
        path: ".".into(),
        excludes: vec!["target".into(), ".git".into(), "node_modules".into()],
        show_hidden: false,
        max_depth: Some(5),
    };
    
    let tree = TreeBuilder::from_config(config).build();
    tree.print();
    
    // Or get the output as string
    let output = tree.to_string();
    println!("{}", output);
}

Dependencies

[dependencies]
clap = { version = "4.5", features = ["derive"] }
dunce = "1.0"
cli-clipboard = "0.4"
clap-version-flag = "1.0.5"

Building from Source

Prerequisites

• Rust 1.60 or higher
• Cargo

Build Steps

git clone https://github.com/cumulus13/tree2
cd tree2

# Debug build

Performance

The Rust version is optimized for performance:

• Zero-cost abstractions
• Minimal memory allocations
• Efficient directory traversal
• Fast pattern matching with HashSet
• Optimized sorting algorithms

Key Improvements in Latest Version

🔧 Fixed: Exact Match Exclusion

Previously, -e .git would also exclude .github and .gitignore. Now it uses exact match only:

// Old (incorrect): .git excludes .github too
entry.starts_with(ex)  // ❌

// New (correct): exact match only
excludes.contains(entry)  // ✅

📋 New: Clipboard Support

Copy tree output with -c flag:

• Automatic ANSI color stripping

• Plain text output for universal compatibility

• Success/error feedback messages
