Understanding Total Lines vs Non-Blank Lines

The tool offers multiple counting methods depending on your needs.

Total Lines counts every line in the document, including empty lines.

Non-Blank Lines only count lines containing visible text or code, ignoring empty spaces.

For example:

Hello

World

• Total Lines: 3
• Non-Blank Lines: 2

This distinction is especially useful for developers, writers, editors, and students.

How Code Analysis Mode Works

The Code Analysis mode is designed for developers who need cleaner code metrics.

Instead of counting every line, the tool separates:

• Executable code lines
• Comment lines
• Blank lines

It recognizes common comment styles used in popular programming languages, making it useful for analyzing source code quality and estimating project size.

This helps developers understand how much actual code exists compared to comments and whitespace.

Detailed Text Statistics You Can Analyze

The Line Counter provides much more than just line totals.

It also calculates:

• Total lines
• Non-blank lines
• Blank lines
• Code lines
• Comment lines
• Duplicate lines
• Total words
• Character count
• Characters without spaces
• Sentence count
• Paragraph count
• Average line length
• Average words per line
• Longest line
• Shortest line
• Estimated reading time

These metrics help writers improve readability while giving developers valuable code insights.
