product name guessing

[TuTAH1]

Hello! I think it would be nice to implement this feature:
If script doesn't find the product by name it takes from product.data, it try to "guess" it that way:

1. Deleting the text in the brackets (Example)
2. Deleting all non-letter symbols ( like ©, ®, etc.)
3. Deleting "-" and all text after it. (Example)

And try to search for a product with a new name. What do you think?

If think I could add a function that is called if there were no results, so the function can broaden the search.
Something like this:

{
  steam: {
    host: ['store.steampowered.com'],
    condition: () => document.querySelector('*[itemprop=name]'),
    products: [{
      condition: Always,
      type: 'pcgame',
      data: () => document.querySelector('*[itemprop=name]').textContent,
      broaden: function(lastProductData) {
        // Remove brackets from search term
        return removeBrackets(lastProductData)
      }
    }]
  }
}

I think it would be better to put it at a higher level, than host-specific. Previously I think to add it globally (so, if it can't find result in any site, it will execute this function), but now I think... to add it globally too, but type-specific filter (switch (type)). Or maybe even some of filters would be global, some – type-specific. I'm just not sure where's the code that makes a window after the result is found.

I have added it on a global level:

Metacritic-userscript/Show_metacritic_ratings.user.js

Lines 320 to 346 in 9ec60d5

	function replaceBrackets (str) {
	str = str.replace(/\([^\(]*\)/g, '')
	str = str.replace(/\[[^\]]*\]/g, '')
	return str.trim()
	}
	function removeSymbols (str) {
	str = str.replace(/[^\s0-9A-Za-zÀ-ÖØ-öø-ÿ]*/gi, '').trim()
	return str.trim()
	}
	const dashRegExp = new RegExp('[-\u2010\u2011\u2012\u2013\u2014\u2015\uFE58\uFE63\uFF0D]')
	function removeAnythingAfterDash (str) {
	str = str.split(dashRegExp)[0]
	return str.trim()
	}
	function broadenSearch (data, step, type) {
	if (type === 'pcgame') {
	if (step > 0) {
	data[0] = replaceBrackets(data[0])
	} else if (step > 1) {
	data[0] = removeSymbols(data[0])
	} else if (step > 2) {
	data[0] = removeAnythingAfterDash(data[0])
	}
	}
	return data
	}

For now the global function only applies to 'pcgame' and it can do the things that you suggested. It goes through three steps, and tries to search after each step. I thought that might be better than removing everything at once.

I also added the product specific way as described before. So it is possible to overwrite the global function in the product with broaden: function(data, step, type) {...\

I have not really tested it yet, that's why I have not increased the version number. If you want to test it, you have to manually install it from the github file.
