page.OutputFormats
Hugo generates one or more files per page when building a site. For example, when rendering home, section, taxonomy, and term pages, Hugo generates an HTML file and an RSS file. Both HTML and RSS are built-in output formats. Create multiple output formats, and control generation based on page kind, or by enabling one or more output formats for one or more pages. See details.
The AlternativeOutputFormats method on a Page object returns a slice of OutputFormat objects, excluding the current output format, each representing one of the output formats enabled for the given page.. See details.
