Backslash Escape/Unescape

​

Use Cases

• Preparing strings for JSON that contain newlines or quotes
• Escaping user input for use in string literals
• Debugging escaped strings by converting them back to readable form
• Copying text from code that contains escape sequences
• Working with shell scripts where quotes and backslashes need escaping
• Preparing regex patterns that contain special characters

​

How It Works

​

Escape Mode (Default)

• \ → \\ (backslash must be escaped first)
• \n (newline) → \\n
• \r (carriage return) → \\r
• \t (tab) → \\t
• " → \\"
• ' → \\'

​

Unescape Mode

​

Input Format

Hello
World	"Test"

Hello\nWorld\t\"Test\"

​

Output Format

Hello\nWorld\t\"Test\"

Hello
World	"Test"

​

Examples

Input:
Line 1
Line 2
Line 3

Output:
Line 1\nLine 2\nLine 3

Technical Details

• escapeBackslash (engine.ts:105-113): Replaces special characters with escape sequences
• unescapeBackslash (engine.ts:115-123): Converts escape sequences back to characters

​

Supported Escape Sequences

​

Performance

• Synchronous processing: Instant client-side conversion
• Sequential replacements: Uses replaceAll for efficiency
• No regex parsing: Simple string replacement for maximum speed

​

Common Patterns

​

JSON String Preparation

{
  "message": "Line 1\nLine 2\nLine 3"
}

​

Shell Script Escaping

echo "She said, \"Hello\" and left"

​

Programming Language Strings
