Isengard file watching + stats

Requires strace

Usage:

isengard yourprogram

Configuration

You can configure it with .isengard file

{
  "include": [],
  "exclude": [],
  "trace": true,
  "exitCodes": []
}

Todo:

• kill child processes if isengard dies
• attach strace to the process
• separate app and index.js
• errors if you try to watch dodgy file
• glob matching
• exclude, include lists
• use trees for caching files
• use md5sum to check for really changed files
