Did you find the add function in the source?

[gafimiv406]

You can use the functions written in the source code like this. Of course, not all of them can be used, and generally public 関数名only functions like the ones below can be used.


addAllThere is also an unpublished function in this source code called , which combines an array with another array and has two ways of using it.

A. addAll(挿入位置, 配列)
B. addAll(配列)
Plain text

Now, let's try adding [3,4,5] after the 1 (second position) in [0,1,2] using method A.

{% set numbers = [0,1,2] %}
{% do numbers.addAll(2, [3,4,5]) %}
{{ numbers }}
HTML + HubL
The result [0, 1, 3, 4, 5, 2]is .

Of course, you can create it using for without using the addAll function.

{% set numbers = [0,1,2] %}
{% for n in [3,4,5] %}
{% do numbers.insert(loop.index + 1, n) %}
{% endfor %}
{{ numbers }}
HTML + HubL
What do you think? The addAll function is more readable than the for function. There are

other useful functions for manipulating associative arrays .put

updateThe put function allows you to dynamically add keys to an associative array. You can see the difference by comparing it with similar functions .

{% set newkey = "KEY_NAME" -%}
{% set dict_var = {"authorName": "Douglas Judy", "authorTitle": "Mastermind" } %}

{# 連想配列のキーに変数newkeyを使用したいけれどそのまま文字として入る #}
{% do dict_var.update({newkey: "Jake"}) %}

{# 連想配列のキーに変数newkeyの値が使用される #}
{% do dict_var.put(newkey, "Mike") %}
{{ dict_var }}

{# 結果
{
authorName=Douglas Judy,
authorTitle=Mastermind,
newkey=Jake,
KEY_NAME=Mike
}
#}
HTML + HubL
Conclusion
As mentioned above, this is not officially documented and may be subject to change. I don't know

where this will be useful, but this is an introduction to how to check for private functions.
