ASP.NET MVC Reference script file with version wildcard (without bundling) - asp.net

Question

In a ASP.NET MVC 4 project, I'd like to reference a versioned script file like this:
// Just some pseudo-code:
<script src="#Latest("~/Scripts/jquery-{0}.min.js")"></script>
// Resolves to the currently referenced script file
<script src="/Scripts/jquery-1.10.2.min.js"></script>
so that when a new Script version is updated via NuGet, the reference is updated automatically. I know of the bundling-and-minification feature, but it's just to much. I just want the little part which resolves the wildcards. My files are already minified, and also I don't want the bundles.
Do you have some smart ideas how to solve this?

Answer 1

Even though it's a little over kill to use the Bundling in MVC, but I think that will be your best bet. It's already been done and proven so why spend more time to write some proprietary code.
That being said, if you want a simple sample of what you can do, then you can try the following.
public static class Util
{
private const string _scriptFolder = "Scripts";
public static string GetScripts(string expression)
{
var path = HttpRuntime.AppDomainAppPath;
var files = Directory.GetFiles(path + _scriptFolder).Select(x => Path.GetFileName(x)).ToList();
string script = string.Empty;
expression = expression.Replace(".", #"\.").Replace("{0}", "(\\d+\\.?)+");
Regex r = new Regex(#expression, RegexOptions.IgnoreCase);
foreach (var f in files)
{
Match m = r.Match(f);
while (m.Success)
{
script = m.Captures[0].ToString();
m = m.NextMatch();
}
}
return script;
}
}
This will return you the last match in your Scripts director or it will return empty string.
Using this call
#Html.Raw(MvcApplication1.Util.GetScripts("jquery-{0}.min.js"))
Will get you this result if 1.8.2 is the last file that matched your string.
jquery-1.8.2.min.js
Hope this will help you get started.
