Add a Prefix to Text Lines Calculator

Adding a prefix to each line of a text is a common task in text processing and formatting, which can be essential for generating structured data, code formatting, logging, or even creating bulleted lists in markdown or HTML documents.

Historical Background

The concept of prefixing text lines has roots in early computing and typesetting, where uniform prefixes were used to indicate special formatting or to denote commented-out sections of code in programming. Over time, this concept has been extended to various contexts, including data serialization, markup languages, and batch processing of textual data.

Calculation Formula

The operation to add a prefix to each line of a text doesn't follow a mathematical formula but rather a simple algorithmic process:

1. Split the input text into lines.
2. Prepend the prefix to each line.
3. Join the lines back into a single text block.

Example Calculation

If you want to add the prefix > to the following text:

Line one
Line two
Line three

The result will be:

> Line one
> Line two
> Line three

Adding prefixes is widely used in:

• Markdown formatting for blockquotes or lists.
• Commenting out blocks of code in programming.
• Log file formatting to include timestamps or severity levels at the beginning of each line.
