Lists in Arcade

JoeBorgione

When constructing a list in a python script, it's easy to accommodate long entries to make them readable by splitting them into several lines:

myList = ['blahblah0', 'blahblah1', 'blahblah2',
          'blahblah3', 'blahblah4', 'blahblah5']‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

However, the same does not hold true in arcade.  I have to construct a list of attributes that goes on ad nauseam for an attribute rule .  Adding attribute field names in an arcade list that goes on seemingly forever is tedious at best.  Is there a way to manage a list such that arcade can be happy with it and I don't go blind?  Can I merge a series of lists together in arcade?  That way I could have multiple lists each of a readable size, and merge them into one 'one the fly' so arcade can read each of the attributes?

Hi Joe Borgione ,

In Arcade you can also split long lists over multiple lines:

<SPAN class="keyword token">var</SPAN> myList <SPAN class="operator token">=</SPAN> <SPAN class="punctuation token">[</SPAN><SPAN class="string token">'blahblah0'</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">'blahblah1'</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">'blahblah2'</SPAN><SPAN class="punctuation token">,</SPAN>
              <SPAN class="string token">'blahblah3'</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">'blahblah4'</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">'blahblah5'</SPAN><SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">;</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

To combine multiple list you don't have the easy sum of the lists as you have in Python but you can do this:

<SPAN class="keyword token">var</SPAN> lst1 <SPAN class="operator token">=</SPAN> <SPAN class="punctuation token">[</SPAN><SPAN class="string token">'blahblah0'</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">'blahblah1'</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">'blahblah2'</SPAN><SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">;</SPAN>
<SPAN class="keyword token">var</SPAN> lst2 <SPAN class="operator token">=</SPAN> <SPAN class="punctuation token">[</SPAN><SPAN class="string token">'blahblah3'</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">'blahblah4'</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">'blahblah5'</SPAN><SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">;</SPAN>

<SPAN class="keyword token">var</SPAN> lst <SPAN class="operator token">=</SPAN> lst1<SPAN class="punctuation token">;</SPAN>
<SPAN class="keyword token">for</SPAN> <SPAN class="punctuation token">(</SPAN><SPAN class="keyword token">var</SPAN> i <SPAN class="keyword token">in</SPAN> lst2<SPAN class="punctuation token">)</SPAN> <SPAN class="punctuation token">{</SPAN>
    lst<SPAN class="punctuation token">[</SPAN><SPAN class="token function">Count</SPAN><SPAN class="punctuation token">(</SPAN>lst<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">]</SPAN> <SPAN class="operator token">=</SPAN> lst2<SPAN class="punctuation token">[</SPAN>i<SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">;</SPAN>
<SPAN class="punctuation token">}</SPAN>

<SPAN class="keyword token">return</SPAN> lst<SPAN class="punctuation token">;</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

...or even this (which will not work for lists with numeric data):

<SPAN class="keyword token">var</SPAN> lst1 <SPAN class="operator token">=</SPAN> <SPAN class="punctuation token">[</SPAN><SPAN class="string token">'blahblah0'</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">'blahblah1'</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">'blahblah2'</SPAN><SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">;</SPAN>
<SPAN class="keyword token">var</SPAN> lst2 <SPAN class="operator token">=</SPAN> <SPAN class="punctuation token">[</SPAN><SPAN class="string token">'blahblah3'</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">'blahblah4'</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">'blahblah5'</SPAN><SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">;</SPAN>
<SPAN class="keyword token">var</SPAN> lst  <SPAN class="operator token">=</SPAN> <SPAN class="token function">Split</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="token function">Concatenate</SPAN><SPAN class="punctuation token">(</SPAN>lst1<SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"#"</SPAN><SPAN class="punctuation token">)</SPAN> <SPAN class="operator token">+</SPAN> <SPAN class="string token">"#"</SPAN> <SPAN class="operator token">+</SPAN> <SPAN class="token function">Concatenate</SPAN><SPAN class="punctuation token">(</SPAN>lst2<SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"#"</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"#"</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN>
<SPAN class="keyword token">return</SPAN> lst<SPAN class="punctuation token">;</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>
