Data inspection
Use template functions to inspect values and data structures.
Use the
debug.Dump function to inspect a data structure:
<pre>{{ debug.Dump .Params }}</pre>
{
"date": "2023-11-10T15:10:42-08:00",
"draft": false,
"iscjklanguage": false,
"lastmod": "2023-11-10T15:10:42-08:00",
"publishdate": "2023-11-10T15:10:42-08:00",
"tags": [
"foo",
"bar"
],
"title": "My first post"
}
Use the
printf function (render) or
warnf function (log to console) to inspect simple data structures. The layout string below displays both value and data type.
{{ $value := 42 }}
{{ printf "%[1]v (%[1]T)" $value }} → 42 (int)
