Add Word Count template in hugo theme
I’m using the Mainroad theme and wanna to append the word count behind the category info.
So I append the blow code in categories.html.
<span class="meta__text post-word-count"> {{ .WordCount }} words</span>
The content of the categories.html.
{{- if .Params.categories }}
<div class="meta__item-categories meta__item">
{{ partial "svg/category.svg" (dict "class" "meta__icon") }}
<span class="meta__text">{{ range $index, $category := .Params.categories }}{{ if gt $index 0 }}, {{ end }}<a class="meta__link" href="{{ "categories/" | relLangURL }}{{ . | urlize | lower }}" rel="category">{{ . }}</a>{{ end }}</span>
</div>
{{ end -}}
<span class="meta__text post-word-count"> {{ .WordCount }} words</span>
Great, it works. You can see there are about 160 words in this article.
