🍬 swt (Sweet)

Turn code maintainability into a measurable metric.

swt is a high-performance analyzer designed to keep your project's architecture clean. It scans your codebase to identify sustainability risks, tangled dependencies, and complex logic patterns that hinder long-term development.

🍭 Sweet Index

swt evaluates your files based on a health threshold. It's not just about finding bugs; it's about identifying code that is becoming a burden to your team.

Key Features

• Sustainability Audits: Automatically find files that have grown beyond manageable limits.
• Decoupling Tracking: Detect excessive dependencies and imports that make code hard to isolate.
• Logic Simplification: Spot deeply nested functions and "God-logic" blocks before they become technical debt.
• Source Cleanup: A precision tool to strip comments and normalize whitespace for cleaner source distribution.
• Multilingual Support: Native understanding of Rust, TypeScript, JavaScript, Java, C#, and Python.
• Automation Ready: Designed for CI/CD with dedicated JSON reporting and minimalist output modes.

Performance

swt is engineered for instant feedback. It processes thousands of files in milliseconds, making it ideal for large monorepos and pre-commit hooks.

Benchmarks (current project)

Benchmark 1: swt .
  Time (mean ± σ):       4.2 ms ±   0.6 ms
  Range (min … max):     3.2 ms …   6.9 ms

Scalability at 13,000+ files

• Execution Time: ~744ms
• Processing Rate: ~18,000 files/sec

Installation

Install the binary via Cargo:

cargo install swt

Usage

Analyze Project

Scan the current directory and list files by maintenance priority:

swt .

Strip Comments

Clean a source file by removing comments and normalizing whitespace:

swt --uncomment src/main.rs

Use --aggressive to also remove documentation headers (like Rust Doc comments /// or JSDoc /** */)

Automated Reporting

Export metrics to JSON for integration with other tools:

swt --json

# You can also generate a JSON file:
swt --json reports.json

Configuration

Control the health thresholds using a .swtrc file in your project root:

{
  "$schema": "https://raw.githubusercontent.com/SirCesarium/sweet/main/schema.json",
  "thresholds": {
    "global": { "max_lines": 250, "max_depth": 5, "max_repetition": 10.0 },
    "overrides": {
      "rust": { "max_imports": 15 },
      "java": { "max_imports": 50 }
    }
  }
}
