Dotenv Validator

Plugin for Nexion that validates .env files against example templates, detecting missing variables and showing env var status in a sidebar panel.

Features

• Auto-detect template — searches for .env.dist, .env.example, .env.sample, .env.template
• Robust parsing — handles comments, quoted values, and KEY=VALUE format
• Full validation — categorizes variables as:
  • ❌ Missing (in example but not in .env)
  • ✅ Present (correctly set)
  • ∅ Empty/default (empty or same as example)
  • ➕ Extra (in .env but not in example)
• Sidebar panel — visual display with status indicators
• Diff command — detailed comparison in a modal window
• Auto-create — creates .env by copying from template on demand
• Project open hook — auto-validates on project open with warning if variables are missing
