A Developer's Guide to the Add/Remove Line Numbers Tool

The Add/Remove Line Numbers tool is a handy utility for anyone who needs to format text for code snippets, legal documents, or academic papers. It allows you to easily add or remove sequential numbering from each line of your text.

Features

• Add Line Numbers: Automatically prepend a number to each line of your text.
• Remove Line Numbers: Intelligently strips common line numbering formats from the beginning of each line.

• Customizable Formatting:
  • Separator: Define the character(s) that appear after the number (e.g., . , : ).
  • Format Style: Choose from different numbering styles, like 1., (1), or [1].
  • Padding: Automatically pad numbers with leading zeros (e.g., 01, 02,... 10) for consistent alignment.
• Live Preview: See the result of adding line numbers in a real-time preview pane.
• Apply Changes: A dedicated "Apply" button lets you commit the changes directly to your input for further editing.
