Slices

Template:

{{ $s := slice "foo" "bar" "baz" }}
{{ range $s }}
  <p>{{ . }}</p>
{{ end }}

Result:

<p>foo</p>
<p>bar</p>
<p>baz</p>

Template:

{{ $s := slice "foo" "bar" "baz" }}
{{ range $v := $s }}
  <p>{{ $v }}</p>
{{ end }}

Result:

<p>foo</p>
<p>bar</p>
<p>baz</p>

Template:

{{ $s := slice "foo" "bar" "baz" }}
{{ range $k, $v := $s }}
  <p>{{ $k }}: {{ $v }}</p>
{{ end }}

Result:

<p>0: foo</p>
<p>1: bar</p>
<p>2: baz</p>

Maps

Template:

{{ $m := slice
  (dict "name" "John" "age" 30)
  (dict "name" "Will" "age" 28)
  (dict "name" "Joey" "age" 24)
}}
{{ range $m }}
  <p>{{ .name }} is {{ .age }}</p>
{{ end }}

Result:

<p>John is 30</p>
<p>Will is 28</p>
<p>Joey is 24</p>

Page collections

Template:

{{ range where site.RegularPages "Type" "articles" }}
  <h2><a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a></h2>
{{ end }}

Result:

<h2><a href="/articles/article-3/">Article 3</a></h2>
<h2><a href="/articles/article-2/">Article 2</a></h2>
<h2><a href="/articles/article-1/">Article 1</a></h2>

Break

Use the break statement to stop the innermost iteration and bypass all remaining iterations.

Template:

{{ $s := slice "foo" "bar" "baz" }}
{{ range $s }}
  {{ if eq . "bar" }}
    {{ break }}
  {{ end }}
  <p>{{ . }}</p>
{{ end }}

Result:

<p>foo</p>

Continue

Use the continue statement to stop the innermost iteration and continue to the next iteration.

Template:

{{ $s := slice "foo" "bar" "baz" }}
{{ range $s }}
  {{ if eq . "bar" }}
    {{ continue }}
  {{ end }}
  <p>{{ . }}</p>
{{ end }}

Result:

<p>foo</p>
<p>baz</p>
