Checks whether a template file exists under the given path relative to the layouts directory.

语法

templates.Exists PATH

A template file is any file living below the layouts directories of either the project or any of its theme components including partials and shortcodes.

The function is particularly handy with dynamic path. The following example ensures the build will not break on a .Type missing its dedicated header partial.

{{ if templates.Exists ( printf "partials/%s" $partialPath ) }}

{{ else }}
  {{ partial "headers/default.html" . }}
{{ end }}
