delimit

Syntax

delimit COLLECTION DELIMIT LAST

delimit called in your template takes the form of

{{ delimit array/slice/map delimiter optionallastdelimiter }}

delimit loops through any array, slice, or map and returns a string of all the values separated by a delimiter, the second argument in the function call. There is an optional third parameter that lets you choose a different delimiter to go between the last two values in the loop.

To maintain a consistent output order, maps will be sorted by keys and only a slice of the values will be returned.

The examples of delimit that follow all use the same front matter:

---
tags:
- tag1
- tag2
- tag3
title: About
---

+++
tags = ['tag1', 'tag2', 'tag3']
title = 'About'
+++

{
   "tags": [
      "tag1",
      "tag2",
      "tag3"
   ],
   "title": "About"
}

<p>Tags: {{ delimit .Params.tags ", " }}</p>

<p>Tags: tag1, tag2, tag3</p>

Here is the same example but with the optional “last” delimiter:

Tags: {{ delimit .Params.tags ", " ", and " }}

<p>Tags: tag1, tag2, and tag3</p>
