Automated Error-Fixing System for Dart - Implementation Plan

This document outlines the motivation, background, goals, and a step-by-step, phase-based plan to develop an automated error-fixing system. The system leverages Dart linter outputs, an LLM (both cloud-based and local), and a JSON-driven transformation engine to automatically fix code issues. It's designed to integrate with CI/CD pipelines and support iterative refinement.

1. Background and Specification Recap 🟢

Motivation

  • Reduce Developer Overhead: Automate repetitive code fixes
  • Improve Code Quality: Enforce coding standards consistently
  • Continuous Improvement: Integrate into CI/CD for ongoing quality assurance
  • Flexibility: Offer both cloud-based (Google Gemini API) and local (llama-cpp) LLM options for rule generation

Context

  • Target Environment: Dart projects using linting tools to generate warnings, errors, and improvement suggestions
  • Core Idea: Inspired by tools like dart fix --apply, we transform lint outputs into JSON-based transformation rules and apply these rules automatically to the codebase

Key Components

  • Dart Linter: Generates a lint output report
  • LLM Analysis Module: Processes lint output to generate JSON rules
  • JSON Rules File: Contains rules (with regex patterns, replacement texts, and descriptions)
  • Automated Fix Engine: Applies the JSON rules to the source code
  • Feedback Loop: Re-runs linting and refines rules if necessary

Goals

  • Automate the process of detecting and fixing lint errors
  • Generate customizable fix rules via an LLM
  • Support both remote and local LLM integration
  • Seamlessly integrate into existing CI/CD pipelines
  • Enable iterative refinement of fixes
