Good people.

I am creating my first theme. I have not yet created a website yet. I am learning as I go. I do intent to use Publii for several sites, but want to have my own themes using CoffeeCup Site Designer.

I created a theme by obliterating the technews theme and get the following error when rendering “Preview your changes”

Rendering process failed
An error occurred during rendering process:

Unexpected identifier

I did try to create a custom helper, isEven, and put it in helpers.js. Here is the code.

/*
 * Custom theme helpers for Handlebars.js
 */

let themeHelpers = {
    getTagColor: function(tag, tagsConfig = '') {
        if(tagsConfig.trim() === '') {
            return 'u-tag--1';
        }

        tagsConfig = tagsConfig.split(',');

        if(tagsConfig.length) {
            tagsConfig = tagsConfig.map(item => item.split('='));

            for(let tagConfig of tagsConfig) {
                if(tagConfig.length !== 2) {
                    continue;
                }

                if(tagConfig[0].trim() === tag) {
                    return 'u-tag--' + tagConfig[1];
                }
            }
        } else {
            return 'u-tag--1';
        }

        return 'u-tag--1';
    }

    isEven: function(value, options) {
        if (value % 2 == 0) {
      return true;
  } else {
            return false;
        }
    }
};

module.exports = themeHelpers;

Here is how I am using it in Handlebars (index.hbs).

{{#each posts}}
    {{#isEven @index}}
    

        

        <h3 class="article-heading">{{title}}</h3>
        <p class="paragraph body-copy">{{{text}}}</p>
        
    

        

            <picture>
            
           </picture>
        
    
    {{else}}
    

        

            

                <picture>
                
               </picture>
            
        
    

        <h3 class="article-heading">{{title}}</h3>
        <p class="paragraph body-copy">{{{text}}}</p>
        
    
    {{/isEven}}

    {{#if @last}}

    {{else}}
        

        <hr>
        
    {{/if}}
  {{/each}}

All the rest of the modifications to the theme come directly from your website — so this is only the tricky part.
