## ⚡ Instant Quickstart

Run immediately anywhere without installing via `uvx`:

```bash
# Verify active .env against .env.example
uvx --from envdoctor-cli envdoctor check

# Enforce bidirectional strict match (zero extra or missing keys)
uvx --from envdoctor-cli envdoctor check --strict

# Safely sync missing keys into .env.example with dummy placeholders
uvx --from envdoctor-cli envdoctor sync

# Audit source code for environment variables you forgot to define
uvx --from envdoctor-cli envdoctor audit ./src
```

Or install globally via **pip**:

```bash
pip install envdoctor-cli
```

## 💥 Problem vs. Solution

### The Pain with Traditional Workflows
- **Silent Production Crashes**: A developer adds `STRIPE_WEBHOOK_SECRET` locally, merges the PR, but forgets `.env.example`. The app deploys and immediately crashes on boot with `KeyError` or `undefined`.
- **Secret Leaks**: When developers try to update `.env.example` manually, real API tokens or database credentials accidentally get committed to Git.
- **Onboarding Friction**: New team members clone the repo, copy `.env.example` to `.env`, and spend hours debugging missing variables that nobody documented.
- **Dead Config Debt**: Variables deleted from code years ago remain in `.env` forever because nobody knows if they are still used.

```

## ⚙️ CLI Command Reference

EnvDoctor provides three focused, high-speed diagnostic commands:

```text
usage: envdoctor [-h] [-v] [--format {text,json}] [-o OUTPUT]
                 {check,sync,audit} ...

Zero-dependency .env linter, template synchronizer, and codebase auditor.

positional arguments:
  {check,sync,audit}
    check               Validate active .env against template (.env.example)
    sync                Append missing keys to .env.example with safe placeholders
    audit               Scan codebase files for unconfigured environment variables

options:
  -h, --help            Show this help message and exit
  -v, --version         Show program version number and exit
  --format {text,json}  Output format (default: text)
  -o, --output PATH     Write output report to file
```

### 1. `envdoctor check`
Validates that all required variables declared in `.env.example` exist in `.env`.

```bash
# Standard check: fail if .env is missing variables required by .env.example
envdoctor check --env .env --example .env.example

# Strict mode: fail if .env has missing OR undocumented extra variables
envdoctor check --strict

# Allow declared variables to be empty strings
envdoctor check --allow-empty
```

**Exit Codes:**
- `0`: All variables present and valid.
- `1`: Contract discrepancy detected (missing or empty variables).
- `2`: File not found or read/write I/O error.

---

### 2. `envdoctor sync`
Safely synchronizes `.env.example` by reading all keys from your local `.env` and generating intelligent, masked placeholder values.

```bash
# Preview changes without modifying file
envdoctor sync --dry-run

# Automatically update .env.example
envdoctor sync
```

**Masking Intelligence Rules:**
- Secret / API keys (`*_KEY`, `*_SECRET`, `*_TOKEN`) $\rightarrow$ `your_api_key_here`
- Port numbers (`*_PORT`, `PORT`) $\rightarrow$ `8080`
- URLs (`*_URL`, `DATABASE_URL`) $\rightarrow$ `postgres://user:password@localhost:5432/dbname`
- Hostnames (`*_HOST`) $\rightarrow$ `localhost`
- Private inline comments (`# my private note`) are **never** exported into `.env.example`.

---

### 3. `envdoctor audit`
Scans your application source code for direct environment lookups across Python, JavaScript, TypeScript, Go, Rust, and PHP:

```bash
# Audit entire source directory
envdoctor audit ./src

# Audit against a specific environment file
envdoctor audit ./src --env .env.production
```

**Recognized Patterns:**
- **Python**: `os.environ["KEY"]`, `os.environ.get("KEY")`, `os.getenv("KEY")`
- **JavaScript / TypeScript**: `process.env.KEY`, `process.env["KEY"]`
- **Go**: `os.Getenv("KEY")`
- **Rust**: `env::var("KEY")`
