Text Wrapper Examples

The Text Wrapper reformats text to fit within a specified line width by inserting line breaks at word boundaries. Below are practical examples for email formatting, code comments, terminal output, and documentation.

Basic Text Wrapping (Width: 72)

// Input (one long line):
"The quick brown fox jumps over the lazy dog. This is a longer sentence that demonstrates how the text wrapper breaks long lines at word boundaries to fit within the specified column width."

// Wrapped at 72 characters:
The quick brown fox jumps over the lazy dog. This is a longer sentence
that demonstrates how the text wrapper breaks long lines at word
boundaries to fit within the specified column width.

Email Formatting (Width: 72)

// Plain text email — traditional standard is 72 characters per line
// Input:
Hi Alice, I wanted to follow up on our conversation from last week about the project timeline. We need to finalize the requirements by Friday and schedule a review meeting for next week. Please let me know your availability.

// Python docstring wrapped at 79 characters (PEP 8):
def calculate_total(cart, address):
    """

    the items in the cart and the user's shipping address.

    Args:

Terminal Output (Width: 80)

// Help text wrapped for 80-column terminal:
// Input:

// Wrapped at 80 characters:
Usage: mytool [OPTIONS] FILE

This tool processes the specified file and applies the configured
transformations. Multiple files can be processed in sequence by
providing multiple FILE arguments.

Indentation Preservation

// Input (indented list items):
"  - This is a list item with a very long description that needs to be wrapped to fit within the column width while preserving the indentation."

// Wrapped at 72 characters (indentation preserved):
  - This is a list item with a very long description that needs to be
    wrapped to fit within the column width while preserving the
    indentation.

Hanging Indent

// Bibliography entry with hanging indent:
// Input:
"Smith, J. (2024). The Complete Guide to Modern Web Development. New York: Tech Publishing House. ISBN: 978-0-123456-78-9."

// Wrapped with hanging indent (first line full width, continuation indented):
Smith, J. (2024). The Complete Guide to Modern Web Development. New
    York: Tech Publishing House. ISBN: 978-0-123456-78-9.

// Definition list with hanging indent:
API (Application Programming Interface): A set of rules and protocols
    that allows different software applications to communicate with
    each other over a network.

Multi-Paragraph Wrapping

// Input (two paragraphs):
"First paragraph with a long line that needs wrapping to fit within the column width.

Second paragraph that also has a long line requiring wrapping at the specified column width."

// Wrapped at 60 characters (paragraphs preserved):
First paragraph with a long line that needs wrapping
to fit within the column width.

Second paragraph that also has a long line requiring
wrapping at the specified column width.

Unwrap Text (Join Wrapped Lines)

// Input (hard-wrapped text):
The quick brown fox jumps over
the lazy dog. This text was
hard-wrapped at 30 characters
and needs to be unwrapped.

// Unwrapped output (single paragraph):

// Useful for:
// - Processing text that was wrapped for display

Python Text Wrapping

import textwrap

text = "The quick brown fox jumps over the lazy dog. This demonstrates Python's textwrap module."

# Wrap at 40 characters
print(textwrap.fill(text, width=40))
# The quick brown fox jumps over the
# lazy dog. This demonstrates Python's
# textwrap module.

# With indentation
print(textwrap.fill(text, width=40, initial_indent='  ', subsequent_indent='  '))

# Wrap and preserve paragraphs
paragraphs = text.split('\n\n')
wrapped = '\n\n'.join(textwrap.fill(p, width=72) for p in paragraphs)

# Unwrap (dedent)
print(textwrap.dedent(text))

Common Column Width Standards

79 characters: Python code (PEP 8)
80 characters: traditional terminal width, many style guides
100 characters: modern wide terminal, some team style guides
120 characters: wide-screen code editors
132 characters: legacy mainframe terminal width

Common Use Cases

Format plain text email to 72-character line width
Wrap code comments to match project line length limit
Prepare terminal help text and usage messages
Format README and documentation files
Unwrap text before re-wrapping at a different width
Normalize line lengths in configuration files
