Group Name Replacement via RegEx Capture - Can't force lowercase group name with \L about unity-addressable-importer

Hi @nindim,

AFAIK, \L, \U, \E which works for Perl, are not supported in .NET regex substitutions: https://social.msdn.microsoft.com/Forums/en-US/5ae2778b-2e1a-4e3b-8471-3fe97e268f72/does-u-convert-to-uppercase-work-in-net-regex?forum=regexp

In the replacement logic, the importer also replaced the path sep (\ or /) with a dash (-) to generate a probable group name. (the method is shared for both addressable name and group name replacement parsing).

unity-addressable-importer/Editor/AddressableImportRule.cs

Lines 150 to 166 in ce93b95

	public string ParseReplacement(string assetPath, string name)
	{
	if (string.IsNullOrWhiteSpace(path) || string.IsNullOrWhiteSpace(name))
	return null;
	var cleanedName = name.Trim().Replace('/', '-').Replace('\\', '-');
	// Parse path elements.
	var replacement = AddressableImportRegex.ParsePath(assetPath, cleanedName);
	// Parse this.path regex.
	if (matchType == AddressableImportRuleMatchType.Regex)
	{
	string pathRegex = path;
	replacement = Regex.Replace(assetPath, pathRegex, replacement);
	}
	return replacement;
	}

I think it would be harder to achieve this unless we switch to another regex library that supports the Perl syntax or implement it ourselves. A workaround is to add a checkbox to the rule to ensure the group name are lowercase.

Thought?

Hey @favoyang,

This would definitely work for our use case!

All the best,
