OK, I believe I found the problem with this test case. The category needs to be wrapped in a hash; as it is, categories is an array of two items. The first item (:category_pages([...])
) gets applied to the template. It has no <title>
, so {{title}}
is null. It does have <category_pages>
, so {{#category_pages}}
section is expanded properly.
The second item is :title("General tasks")
. So this time through {{#categories}}
it fills in {{title}}
, but the {{#category_pages}}
section becomes null.
It took me a long time to figure this out, because the following does not wrap a hash around it as I'd expected:
my %h = categories => [
{
category_pages => [
{title => "Perl 6",
url => "https://www.perl6.org"},
{title => "Perl 6 Modules",
url => "https://modules.perl6.org"}],
title => "General tasks"
}
];
I'm a a few years behind on P6 syntax and it appears that [ { foo => bar } ]
flattens the {}
out. I'm sure there's a good reason for it. It needs a comma at the end to force it to keep the hash. So the following works as desired:
my %h = categories => [
{
title => "General tasks",
category_pages => [
{ title => "Perl 6", url => "https://www.perl6.org" },
{ title => "Perl 6 Modules", url => "https://modules.perl6.org" },
],
},
];
my $html = q:to/EOF/;
{{#categories}}
{{ title }} <!-- should be first item -->
{{#category_pages}}
{{ title }} : {{ url }}</br>
{{/category_pages}}
{{/categories}}
EOF
is Template::Mustache.render($html, %h),
q:to/EOF/,
General tasks <!-- should be first item -->
Perl 6 : https://www.perl6.org</br>
Perl 6 Modules : https://modules.perl6.org</br>
EOF
;
Hello, I am seeing weird ordering on the rendered output when I provide the following as
