# Configuration Format Templates

Jinja2 templates for generating configuration files in different formats.

## Templates

### `toml.j2`

Generate TOML configuration files from Nickel JSON output.

Usage:
```bash
nickel export vapora.solo.ncl | \
  jinja2 templates/configs/toml.j2 > vapora.toml
```

Output: TOML format compatible with services

### `yaml.j2`

Generate YAML configuration files from Nickel JSON output.

Usage:
```bash
nickel export vapora.multiuser.ncl | \
  jinja2 templates/configs/yaml.j2 > vapora.yaml
```

Output: YAML format for Kubernetes, Ansible, etc.

### `json.j2`

Pass-through JSON formatting with pretty-printing.

Usage:
```bash
nickel export vapora.enterprise.ncl | \
  jinja2 templates/configs/json.j2 > vapora.json
```

Output: Formatted JSON

## Template Format

Templates iterate over the configuration object:

```jinja2
{% for section, values in config.items() %}
[{{ section }}]
{% for key, value in values.items() %}
{{ key }} = {{ format_value(value) }}
{% endfor %}
{% endfor %}
```

## Workflow

```
Nickel Config File (.ncl)
    ↓
Export to JSON (nickel export)
    ↓
Render Template (jinja2)
    ↓
Output File (TOML, YAML, JSON, etc.)
```
