Variable Interpolation

Files can contain template place holders for other config keys. Placeholders are enclosed with squiggly braces ({{PLACEHOLDER}}).

• Placeholders can refer to nested keys using dot (.) notation: {{PARENT_KEY.NESTED_KEY}}

• Placeholders can refer to nested list items using at (@) notation: {{PARENT_KEY@1}}

• Placeholders may only reference number or string values.

File Types

• A File with no extension has a value that is UTF-8 encoded and can contain interpolated variables.

• .json will automatically be decoded as JSON then each value will be interpolated.

• .yaml will automatically be decoded as YAML then each value will be interpolated.

• .bin will not be UTF-8 decoded, will not be interpolated, and will be loaded as binary.

• .uri will be decoded as a UTF-8 string then interpolated and each interpolated value will be URL encoded.
