Would be cool if it was possible to add: backspace=”” parameter to a get_list tag ;)
The current version seems to wig out and backspace the variables inside the list..

I think you may have been using an older version of Stash? Backspace is applied to the whole list for a long while now.

I’m having an issue using backspace on a nested get_list. Should this work? I’m trying to output the categories for each entry. It’s still outputting the comma + space after each category.
Setter
{!-- Articles --}
{exp:stash:set_list name="articles" parse_tags="yes" parse_depth="2"}
{exp:channel:entries
channel="news"
dynamic="no"
orderby="sticky|entry_date"
sort="desc|desc"
sort_type="numeric|numeric"
disable="member_data|category_fields"
}
{stash:id}{entry_id}{/stash:id}
{stash:sticky}{sticky}{/stash:sticky}
{stash:title}{title}{/stash:title}
{stash:summary}{article_summary}{/stash:summary}
{stash:date}{entry_date}{/stash:date}
{stash:url}{page_url}{/stash:url}
{stash:image}{article_featured_image}{/stash:image}
{exp:stash:set_list:nested name="this_article_categories" parse_tags="yes" context="{entry_id}"}
{categories}
{stash:category_name}{category_name}{/stash:category_name}
{stash:category_url_title}{category_url_title}{/stash:category_url_title}
{/categories}
{/exp:stash:set_list:nested}
{/exp:channel:entries}
{/exp:stash:set_list}
Getter
{!-- Get Articles --}
{exp:stash:get_list name="articles" limit="2" parse_conditionals="yes" prefix="news" process="end"}
<article>
<header>
<div class="meta">{news:date format="%M %j, %Y"}</div>
<h1 class="gamma"><a href="{news:url}">{news:title}</a></h1>
<p>
{exp:stash:get_list:nested name="this_article_categories" backspace="2" context="{news:id}"}
<a href="{category_url_title}">{category_name}</a>,
{/exp:stash:get_list:nested}
</p>
</header>
<div class="article-body">
{news:summary}
</div>
<p class="read-more"><a href="{news:url}">Continue reading <i class="ss-gizmo ss-right"></i></a></p>
</article>
<hr>
{/exp:stash:get_list}

The backspace parameter applies to the output of the whole list, so will only remove the very last character(s). Note also that a space is a character, so you should use trim=“yes” when setting or getting your list to remove spaces and line breaks, or do it manually:
{exp:stash:get_list:nested name="this_article_categories" backspace="2" context="{news:id}"}<a href="{category_url_title}">{category_name}</a>, {/exp:stash:get_list:nested}
