Build Laser ⚡️

A beautiful, readable, and intelligent wrapper for Dart's build_runner.

Stop scrolling through thousands of lines of terminal noise. Build Laser parses your build output in real-time, hides the clutter, highlights the slow tasks, and gives you a precise progress bar based on historical performance.

✨ Features

• ⚡️ Noise Reduction: Automatically hides tasks that take 0s, keeping your console clean.
• 📊 Live Progress Bar: Learns from your previous builds to show a "Time Remaining" estimate and a visual progress bar.
• ⚠️ Warning Collector: Captures W lines (warnings) and re-prints them in a summary at the end. No more missing deprecation warnings in the scroll-back.
• 🧹 Deep Clean: A built-in command to nuke all generated files (.g.dart, .freezed.dart, etc.) and reset the cache.
• ⏱ Performance Insights: Highlights slow builders in Red so you know what is slowing you down.

🚀 Installation

You can install it globally to use it in any project:

dart pub global activate build_laser

Or add it to your project as a dev dependency:

dart pub add --dev build_laser

🛠 Usage

Standard Build

By default, running build_laser is equivalent to running dart run build_runner build --delete-conflicting-outputs.

build_laser

Watch Mode

Pass any arguments you normally would. They are forwarded directly to build_runner.

build_laser watch

Deep Clean

Delete all generated files (.g.dart, .freezed.dart, .hive.dart, etc.) and clear the build cache.

build_laser clean

🧠 How the Progress Bar Works

1. First Run: build_laser doesn't know how many tasks your project has, so it shows a Spinner (⠋) and a timer.
2. Learning: Upon successful completion, it saves your project's metrics (Total Actions & Total Time) to .dart_tool/build_laser_cache.json.
3. Subsequent Runs: It uses that cache to render a Determinate Progress Bar (████░░ 60%) and estimates the remaining time.

❌ Handling Errors

If the build fails, build_laser will pass the exit code through (useful for CI/CD) and print the critical errors in Red so they stand out immediately.
