User:BrownHairedGirl/AWB modules/Replace title year or title decade in category redirects

This is a quick and dirty AWB custom module to replace {{title year}} or {{title decade}} in category redirects, to avoid the proem of Template:Resolve category redirect#Templates.

I used it for these edits. Feel free to use or modify it at your own risk.

public string ProcessArticle(string ArticleText, string ArticleTitle, int wikiNamespace, out string Summary, out bool Skip)
{
    Skip = false;

    string nuArticleText = ArticleText;
    string myTitleYearDec = "";
    
    Match m = Regex.Match(ArticleTitle, @"^Category:(?<yeardec>\d\d\d(\d|0s)) ((dis)?establishments )?in ");
    if (m.Success) {
        myTitleYearDec  = m.Groups["yeardec"].Value;
    }
    else {
        Skip = true;
        Summary = "";
        return ArticleText;
    }
    m = Regex.Match(myTitleYearDec, @"0s$");
    if (m.Success) {
        nuArticleText = Regex.Replace(ArticleText, @"\{\{\s*title\s*decade\s*\}\}s", myTitleYearDec, RegexOptions.IgnoreCase);
    }
    else {
        nuArticleText = Regex.Replace(ArticleText, @"\{\{\s*title\s*year\s*\}\}", myTitleYearDec, RegexOptions.IgnoreCase);
    }

    string oldredir = Regex.Replace(ArticleText, @"(?<!(year|decade))\}\}.+$", "}}", RegexOptions.Singleline);
    string nuredir = Regex.Replace(nuArticleText, @"\}\}.+$", "}}", RegexOptions.Singleline);
    Summary = oldredir + " → " + nuredir;
    return nuArticleText;
}
