This is Hugo. We have a better way. If this were your "post/tag/list.html" instead, all of those problems are fixed automatically (this first version separates all of the operations for ease of reading; the combined version will be shown after the explanation).
<!-- post/tag/list.html -->
- {{ with.Params.tags }}
+ {{ with .Params.tags }}
<div class="tags-list">
Tags:
{{ $sort := sort . }}
In this version, we are now sorting the tags, converting them to links with "post/tag/link.html", cleaning off stray newlines, and joining them together in a delimited list for presentation. That can also be written as:
<!-- post/tag/list.html -->
- {{ with.Params.tags }}
+ {{ with .Params.tags }}
<div class="tags-list">
Tags:
{{ delimit (apply (apply (sort .) "partial" "post/tag/link" ".") "chomp" ".") ", " }}
