The Universal Line Counter & Code Metrics Analyzer by RiazHub is a modern, high-speed, privacy-first developer utility designed to diagnose and optimize the structure of your codebases, documents, and log files in real time. Unlike basic text counters that merely count raw carriage returns, this tool calculates Physical Lines of Code (LOC), Source Lines of Code (SLOC / Logical Lines), Comment Ratios, Blank / Whitespace Density, and Duplicate Strings. It features a synchronized line-number gutter with color-coded syntax markers, interactive line-length distribution charts that flag PEP 8 / linter warnings (>80 and >120 characters), and 1-click line manipulation actions (blank removal, deduplication, whitespace trimming, sorting, and numbering). All calculations run 100% client-side inside your browser for zero data leakage, and results can be exported instantly as structured JSON, CSV, or sanitized text files.

Physical Lines of Code (LOC) counts the total number of lines in a file, including blank lines, formatting whitespace, and documentation comments. While useful for estimating file size and scroll depth, physical LOC can artificially inflate code volume.

Source Lines of Code (SLOC / Logical Lines) isolates executable instructions and structural statements by filtering out empty rows and comment blocks. SLOC provides an accurate benchmark for measuring software complexity, developer productivity, code density, and technical debt.

Industry coding standards (such as Python PEP 8, the Google JavaScript Style Guide, and Linux Kernel Guidelines) emphasize limiting line length between 79 and 120 characters. This practice:

Prevents Horizontal Scroll Fatigue: Allows engineers to view multiple split-screen editor panes and side-by-side Git diffs without horizontal scrolling.
Enhances Code Review Ergonomics: Improves readability on tablet screens, laptops, and Pull Request inspection tools.
Encourages Modularity: Overly long lines often signal deeply nested logic or convoluted chained statements that should be refactored.

Yes, 100% secure. All line scanning, regex tokenization, comment parsing, and metrics calculations are computed purely within your local browser environment using JavaScript (ES6+). Zero bytes of code, logs, or plain text are ever transmitted to RiazHub servers or any external third-party API.
