🎨 GrepLogViewer

Regex-based log viewer — color highlighting, auto-folding, and keyword timeline

📖 Usage

Open log file -> set/import/apply rules -> Click Go

✨ Features

🎨 Regex Group Coloring & Auto-Folding

Assign colors to regex groups. Matched lines get full-line highlights. Unmatched lines are auto-folded — only relevant content stays visible.

🔍 Keyword Substring Highlighting

Substring-level coloring that never clashes with group colors (range subtraction).

⏱️ Fold Time Annotations

With a time pattern configured, each folded region displays hidden line count + time span.

🕐 Keyword Timeline

Bottom-panel time axis chart showing keyword hit distribution over time.

🖱️ Right-Click Grep

Select text → right-click → Grep Keyword / Grep Function → searches associated code directories, output to terminal.

Supports ;-separated dirs, ! exclusion, ${VAR} environment variables.

📦 Config Sharing

Save named configs (User or Workspace scope), export as JSON, share with your team.

🎯 Use Cases

• Log debugging: color-code by module (e.g., kernel module → green, HAL → yellow), auto-fold everything else. 30,000 lines → 500 at a glance
• Trace analysis: correlate timestamps across keyword occurrences with the timeline
• Code auditing: grep keywords or function definitions across code directories from any file
