Complexity Indicator

What it does

Complexity Indicator helps developers analyze and visualize code complexity in real time. Get actionable insights like cyclomatic complexity, maintainability index, and nesting depth directly inside VS Code.

Extension for Visual Studio Code - Analyze and visualize file complexity

A VS Code extension that analyses the complexity of your active file in real time and displays a rich metrics dashboard in the sidebar — works with any language. A single weighted score that combines all signals below. Lower is better. Aim for ≤ 40. Based on the Microsoft Maintainability Index formula, normalised to a 0 – 100 scale. Higher is better. MI = 171 − 0.23 × CC − 16.2 × ln(LOC) + 50 × √(2.46 × commentRatio) Normalised = MAX(0, MI × 100 / 171) Range Rating ≥ 85 Excellent ≥ 70 Good ≥ 50 Fair < 50 Poor — consider refactoring Lines of Code (LOC) Non-blank, non-comment lines — only the lines that actually execute. Block comments ( /* */ ) and line comments ( // ) are excluded. Total…from marketplace.visualstudio.com

  Hey HN, We’re building Weave: an ML-powered tool to measure engineering output, that actually understands engineering output! Why? Here’s the thing: almost every eng leader already measures output - either openly or behind closed doors. But they rely on metrics like lines of code (correlation with effort: ~0.3), number of PRs, or story points (slightly better at ~0.35). These metrics are, frankly, terrible proxies for productivity. We’ve developed a custom model that analyzes code and its impact directly, with a far better 0.94 correlation. The result? A standardized engineering output…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https:&#x2F;&#x2F;text.blogosphere.app&#x2F; Non-minimal: https:&#x2F;&#x2F;blogosphere.app&#x2F; If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
