templates.Exists		Checks whether a template file exists under the given path relative to the `layouts` directory.		2018-11-01	2018-11-01	2018-11-01	functions		docs parent functions		templates template layouts	templates.Exists PATH		0.46			false	false

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.

{{ $partialPath := printf "headers/%s.html" .Type }}
{{ if templates.Exists ( printf "partials/%s" $partialPath ) }}
  {{ partial $partialPath . }}
{{ else }}
  {{ partial "headers/default.html" . }}
{{ end }}
