How to create a page from a generator plugin?

Help

Oh I got it! I got clues from the Jekyll Feed plugin, which generates a feed.xml file based on pages on the site.

It uses PageWithoutAFile so it doesn’t get the read error. See jekyll-feed source.

Here is my plugin. It generates a file my-file.xml with one row abcdef.

module SamplePlugin
  class MyPageGenerator < Jekyll::Generator
    safe true

    def generate(site)
      dir = '.'
      name = 'my-file.xml'

      site.pages << Jekyll::PageWithoutAFile.new(site, site.source, dir, name).tap do |file|
        file.content = 'abcdef'
        file.data.merge!(
          "layout"     => nil,
          "sitemap"    => false,
        )
        file.output
      end
    end
  end
end

I made layout nil so there is nothing else on the page. OR you can use a layout - the abcdef content gets inserted as {{ content }} of the layout.

To do that, replace nil above, or take out the merge and set layouts for all pages to be page in config file.
