Paste Utilities

Detailed Description

Utilities for validating paste data safety.

Basic Usage

Use ghostty_paste_is_safe() to check if paste data contains potentially dangerous sequences before sending it to the terminal.

Example

#include <stdio.h>
#include <string.h>
#include <ghostty/vt.h>
 
int main() {
  const char* safe_data = "hello world";
  const char* unsafe_data = "rm -rf /\n";
 
  if (ghostty_paste_is_safe(safe_data, strlen(safe_data))) {
    printf("Safe to paste\n");
  }
 
  if (!ghostty_paste_is_safe(unsafe_data, strlen(unsafe_data))) {
    printf("Unsafe! Contains newline\n");
  }
 
  return 0;
}

Functions
bool	ghostty_paste_is_safe (const char *data, size_t len)

Function Documentation

ghostty_paste_is_safe()

bool ghostty_paste_is_safe	(	const char *	data,
		size_t	len )

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.

Parameters

data	The paste data to check (must not be NULL)
len	The length of the data in bytes

Returns

true if the data is safe to paste, false otherwise
