hasLiquidSyntax() function

Checks whether a string contains Liquid template syntax.

Signature

export declare function hasLiquidSyntax(value: string): boolean;

Parameters

Parameter	Type	Description
value	string	The string to check for Liquid syntax.

Returns

boolean

true if the string contains Liquid syntax markers, false otherwise.

Remarks

This utility function detects the presence of Liquid template markers in a string, indicating that the string requires template processing.

Liquid syntax patterns detected:

1. Variable output: {{ marks the start of a variable interpolation (e.g., {{ package.name }}).
2. Control flow: {% marks the start of a tag for logic or iteration (e.g., {% if condition %}, {% for item in array %}).

The function uses a regular expression to efficiently scan the string for these markers without needing to check for both patterns separately. This is more efficient than calling includes() twice and provides a single point of maintenance for Liquid syntax detection logic.

Common usage:

• Determine whether to process a value through the Liquid engine.
• Skip unnecessary template evaluation for static strings.
• Validate configuration values for template content.
