//! Utilities for validating paste data safety.
//!
//! # Example
//!
//! ```rust
//! use libghostty_vt::paste;
//!
//! let safe_data = "hello world";
//! let unsafe_data = "rm -rf /\n";
//!
//! if paste::is_safe(safe_data) {
//!     println!("Safe to paste");
//! }
//!
//! if !paste::is_safe(unsafe_data) {
//!     println!("Unsafe! Contains newline");
//! }
//! ```

use crate::ffi;

/// Check if paste data is safe to paste into the terminal.
///
/// Data is considered unsafe if it contains:
///   * Newlines (`\n`) which can inject commands
///   * The bracketed paste end sequence (`\x1b[201~`) which can be used to exit bracketed paste
///     mode and inject commands
///
/// This check is conservative and considers data unsafe regardless of current terminal state.
