NeqHandlebarsHelper (Terminalfour Handlebars Helpers (Version 8.4.0-FINAL))

java.lang.Object
- com.terminalfour.publish.handlebars.helper.BaseHelper
- - com.terminalfour.publish.handlebars.helper.utility.NeqHandlebarsHelper

All Implemented Interfaces:

```
@Component
public class NeqHandlebarsHelper
extends BaseHelper
```
The {{neq ...}} handlebars helper extends the core neq that is provided as part of handlebars.java.
This extended version checks if two values are different.

Usage

The {{neq ...}} helper takes the following format.
```
        {{[#]neq [value1] [value2]}}
 
```
Attributes
- #: should be added before the helper name when using it as a block expression, otherwise will be considered as standard expression.
- value1: string/numeric value or handlebars expression. For example "first value" or (nav id="2").
- value2: string/numeric value or handlebars expression. For example "second value" or (nav id="3").
Examples

Block expression
```
        {{#neq value1 value2}}
                <p>To be displayed when they are not equal</p>
        {{else}}
                <p>To be displayed when they are equal</p>
        {{/neq}}
 
```
This would return <p>To be displayed when they are not equal</p> in case the values are not equal, otherwise <p>To be displayed when they are equal</p>.

Standard expression
```
        {{#or (neq value1 value2) (neq value1 value3)}}
                <p>To be displayed when they any not equal</p>
        {{/or}}
 
```
This would return <p>To be displayed when they are not equal</p> in case any of the two neq expressions are true (their values are not equal).
