How do I make my own array?

[Lindsay Ward]

Hi there,
I am using Liquid with Planning Center Online (http://
www.planningcenteronline.com/) to make a custom report. I have some
variables provided to me, but I can't figure out how to just use
these, and I need my own array.
I can not see any syntax in the "Liquid for Designers" to show a user-
created array. I have tried lots of things, including the following,
none of which work:

{% assign array = 1,2,3,4,5,6,7 %}
{% assign positions = ('Leader', 'Sound', 'Words') %}
{% assign positions = ['Leader', 'Sound', 'Words'] %}
{% assign positions = {Leader', 'Sound', 'Words'} %}
I even tried the one in the documentation example (but it's a comment
in the example):
# array = [1,2,3,4,5,6]
{% for item in array limit:2 offset:2 %}
... so I tried
{% assign array = [1,2,3,4,5,6] %}
{% for item in array limit:2 offset:2 %}

Could someone please let me know if and how I do this - and perhaps
this sort of thing could be added to the basic page. It would be great
if each example was stand-alone; like the one above could be copied
and would work, not assuming some variable 'array' already exists.

Thank you!

Bump...
Is it possible to make my own array? It would really help!
Thanks.

 try using drops!
                                                                                                                                         
  1 require 'rubygems'
  2 require 'liquid'
  3 class MyVarsDrop < Liquid::Drop
  4   def array
  5     [1,2,3,4,5,6,7]
  6   end
  7   def positions
  8     ['Leader', 'Sound', 'Words']
  9   end
 10 end
 11 puts Liquid::Template.parse("
 12 {% for item in my.array limit:2 offset:2 %}
 13     {{ item }}
 14 {% endfor %} ").render('my' => MyVarsDrop.new)

Thanks for the response!

I'm not sure that I have access to this, however. I am an end user
making a report using HTML, Liquid and the template variables I've
been provided with.
I can not customise the code at the server end.

Lindsay,

you cannot declare or alter arrays using Liquid's core functions.

However, what are you trying to achieve? Maybe there's a workaround...

Cheers

Stefan

Liquid can't do this currently but i like the syntax. This would be a
nice addition.

I'm simply using the "split" method. For example ...

{% assign myArray = "one|two|three" | split: "|" %}

[Kristian Brito]

I had an instance where I had to define an array or declare an array in liquid and this is what I cam up with that worked:

Using the split filter

{% assign my_array = "" | split: ""  %}

Then to add to my array, I would simply overwrite my array with my_array plus the new item I push to it:

{% assign my_array = my_array | push: "array_item" %}

I hope this helps someone.
