v0.6.0

What's New

Themed CLI output for all subcommands — bub status, bub health, bub doctor, bub version, bub config, and bub export now produce colorized, themed output using your active theme palette.

Features

• cliout package with CLIStyles, RenderBar, ScoreColor, VisualPad helpers
• loadCLIStyles() bridge connecting ThemePalette to CLI output
• Threshold-colored progress bars, health score coloring, themed check symbols
• Badge-style labels with consistent styling across all commands

Bug Fixes

• Fixed subcommand routing — bub version, bub status, etc. now work instead of always launching the TUI
• Fixed label alignment in status output
• Fixed pre-rendered ANSI codes interfering with badge backgrounds

v0.1.4

bubbleMonitor v0.1.4

Previously, the Health Score (0-100%) used internal constants to decide when to penalize your score. Now, it respects your configuration.

• Threshold Sync: The score now strictly follows the thresholds you defined in config.json. If you set your CPU warning at 50%, the score will drop the moment you cross 50%.
• Custom Weights: You can now fine-tune exactly how much the score drops for each issue via the new health_weights config.
  How to Configure
  Add health_weights to your config.json to override the defaults:

{
  "thresholds": {
    "CPU": 80.0,
    "Memory": 90.0,
    "Disk": 95.0,
    "Temperature": 85.0
  },
  "health_weights": {
    "cpu_critical": 30,  // -30 points if CPU > 80%
    "cpu_high": 10,      // -10 points if CPU > 56% (70% of threshold)
    "mem_critical": 30,
    "mem_high": 10,
    "disk_critical": 50, // Severe penalty for full disk
    "temp_critical": 30,
    "temp_high": 10
  }
}

Fixes & Improvements

• Fix: Health calculation logic no longer ignores user-defined thresholds.
• Fix: Removed hardcoded "magic numbers" from analysis logic.
• Improvement: Better default weight fallback if config is missing.

v0.1.3 - Enhanced CPU Monitoring & Performance

bubbleMonitor v0.1.3 - Enhanced CPU Monitoring & Optimization

This release addresses user feedback regarding high resource usage and confusion about CPU metrics >100%.

🚀 New Features

Normalized CPU Usage (Btop Style)

By default, Linux reports CPU usage as the sum of all cores (e.g., 200% = 2 full cores). This can be confusing.
We've added a Normalized Mode option!

• Raw Mode (Default): Shows total usage (e.g., 400% on 4 cores). Accurate for capacity planning.
• Normalized Mode: Shows 0-100% scale (divided by core count). Better for "how busy is this process relative to the whole machine".

How to use:

• Press n to toggle instantly.
• Or change "Process CPU" in the Settings menu (.).

⚡ Performance Improvements

We addressed reports of high CPU usage by bub itself (17.5%):

• Optimized Rendering: The process list rendering engine was rewritten to pre-allocate styles, eliminating thousands of memory allocations per frame.
• Smarter Updates: Background analysis logic was split to avoid redundant calculations, reducing CPU overhead during monitoring cycles.
• Memory Fixes: Fixed a potential memory leak in process history tracking.

🛠️ Fixes

• Fixed stale data in history graphs.
• Improved responsiveness of the settings menu.

v0.1.1 - Stability and Bug Fixes

v0.1.1 - Stability and Bug Fixes

This release focuses on improving stability and fixing critical bugs discovered during code review.

🐛 Bug Fixes

Critical

• Fixed potential race condition in RingBuffer

  • Added sync.RWMutex to protect concurrent access to history buffers
  • Future-proofs against background tasks accessing metrics history
  • Verified with race detector tests

• Prevented memory leak in string interner

  • Global interner was accumulating strings indefinitely
  • Now prunes cache when it exceeds 5000 entries
  • Prevents memory issues during long monitoring sessions

• Fixed unsafe type assertion in slice pool

  • GetProcSlice() now uses comma-ok idiom
  • Returns fresh slice if pool gets corrupted instead of panicking

High Priority

• Added proper error handling for CSV exports

  • Previously, write operations silently ignored errors
  • Users now get clear feedback if snapshot export fails
  • Prevents corrupted files being reported as successful

• Removed duplicate code (copy-paste error)

  • Fixed triple assignment to m.LastError in help overlay handler
