{{#match}} allows for simple comparisons, and executing different template blocks depending on the outcome. Like all block helpers, {{#match}} supports adding an {{else}} block or using ^ instead of # for negation - this means that the {{#match}} and {{else}} blocks are reversed if you use {{^match}} and {{else}} instead. In addition, it is possible to do {{else match ...}}, to chain together multiple options like a switch statement.

​
Example usage

The match helper is handy when paired with custom theme settings using @custom: 
{{!-- Adds the 'font-alt' class when the Typography setting is set to 'Elegant serif' --}}
<body class="{{body_class}} {{#match @custom.typography "Elegant serif"}}font-alt{{/match}}">
Supports various operators and else blocks: 
{{#match @custom.color_scheme "!=" "Dark"}}...{{else}}...{{/match}}

​
Operators

Match supports the following operators
  • = - equals (default when no operator provided)
  • != - not equals
  • > - greater than
  • >= - greater than or equals
  • < - less than
  • <= - less than or equals
  • ~ - contains
  • ~^ - starts with
  • ~$ - ends with

​
Equality

match supports comparing values for equality, which is the default behaviour: 
{{#match @custom.color_scheme "=" "Dark"}}...{{else}}...{{/match}}

{{!-- Can be shortened to: --}}
{{#match @custom.color_scheme "Dark"}}...{{else}}...{{/match}}
The equality test can also be negated: 
{{#match @custom.color_scheme "!=" "Dark"}}...{{else}}...{{/match}}

​
String comparisons

Support for contains ~, starts with ~^ and ends with ~$, using the same syntax as NQL filtering 
{{!-- slug starts with #episode- --}}
{{#match slug "~^" "hash-episode-"}}{{/match}}

​
Numeric comparisons

The match handler supports >, <, >= and <= operators for numeric comparisons. 
{{#match posts.length ">" 1}}...{{else}}...{{/match}}

​
Evaluation rules

Values passed to match are tested according to their value as well as their type. For example: 
{{!-- Returns true/false --}}
{{#match feature_image true}}...{{else}}...{{/match}}

{{!-- Always returns false --}}
{{#match feature_image 'true'}}...{{else}}...{{/match}}
match can also be used to test boolean values similar to if: 
{{!-- Default behaviour is to test if a value is truthy --}}
{{#match featured}}...{{else}}...{{/match}}
