VeryPretty

A high-performance file prettifier built with Rust that automatically formats minified code and copies the result to your clipboard.

Features

• Extremely Fast: Uses SWC (Speedy Web Compiler) for JavaScript/TypeScript parsing - one of the fastest parsers available
• Auto-detection: Automatically detects file types (JavaScript, TypeScript, JSON) based on extension and content
• Clipboard Integration: Automatically copies prettified content to your clipboard
• Linux Optimized: Enhanced clipboard support for both X11 and Wayland with proper timing
• Large File Support: Optimized for handling very large minified files with async I/O
• Cross-platform: Works on Linux, macOS, and Windows

Supported File Types

• JavaScript (.js, .mjs, .cjs)
• TypeScript (.ts, .mts, .cts)
• JSON (.json)

Installation

From crates.io (Recommended)

cargo install verypretty

After installation, you can use the pretty command from anywhere:

pretty myfile.js

From Source

# Clone and build
git clone https://github.com/RanMewo/verypretty
cd verypretty
cargo build --release

# The binary will be at target/release/pretty
# Optionally copy to your PATH
sudo cp target/release/pretty /usr/local/bin/

Usage

Basic Usage

# Prettify a minified JavaScript file
pretty bundle.min.js

# Prettify a JSON file
pretty package.json

# Prettify TypeScript
pretty app.ts

# Just print without clipboard
pretty large-file.js --no-clipboard

# Force file type
pretty myfile --type js
pretty myfile --type json

Performance

VeryPretty is designed for maximum performance:

• Uses SWC parser (written in Rust) - significantly faster than Node.js-based tools
• Async I/O for handling large files efficiently
• Optimized release builds
• Minimal memory footprint

Linux Clipboard Support

VeryPretty includes enhanced Linux clipboard support:

• X11 Support: Works with traditional X11 clipboard managers
• Wayland Support: Full Wayland clipboard integration via wl-clipboard-rs
• Auto-detection: Automatically uses the appropriate clipboard backend

The clipboard functionality has been specifically optimized for Linux environments to avoid the common "clipboard dropped too quickly" issues.
