Add option eleventyExcludeFromCollections to virtual template and set to true as default

[lsolesen]

Right now the page created by the virtual template is added to the collections. Add the option to the virtual template options, so you can exclude the rss feed from the collections. Set to true, so it happens by default.

I expected to be able to set eleventyExcludeFromCollections using the templateData option, but it doesn't seem to have any effect, with the feed.xml file still appearing in the all collection.

eleventyConfig.addPlugin(feedPlugin, {
  type: "atom",
  outputPath: "/feed.xml",
  collection: {
    name: "blog",
    limit: 10,
  },
  metadata: {
    ...
  },
  templateData: {
    eleventyExcludeFromCollections: true,
  },
});

If it isn't possible to do this via templateData, then adding some setting for it would be useful.

I'm not sure if having it set by default would mesh with user expectations, though. Is there any existing precedent for an Eleventy page to be excluded from collections by default?

If collection.name is set, we do add eleventyExcludeFromCollections to the virtual template data cascade:

eleventy-plugin-rss/src/virtualTemplate.js

Lines 140 to 148 in 76d452a

	if(options.collection.name === "all") {
	eleventyExcludeFromCollections = true;
	eleventyImport = {};
	} else {
	eleventyExcludeFromCollections = [ options.collection.name ]
	eleventyImport = {
	collections: [ options.collection.name ],
	};
	}

I don’t think it would be necessary if the template isn’t consuming collections?
