HTML ListFormatter

mxmissile — Thu, 18 Jun 2009 21:10:00 GMT

My version of the ListFormatter(s) posted here. Based off the code posted by Joe Chung in the comments. The only real modification was I added overloads for params Func<T, object> and in inline format string. This allows strongly typed code like this:

<%=Model.Contacts.ToFormattedList(ListType.Unordered, "{0} - {1}", x => x.FirstName,x => x.LastName)%>

Useful? Maybe, maybe not.

 public enum ListType
    {
        Ordered,
        Unordered,
        TableCell,
        TableRow
    }

    public static class ListFormatter
    {
        public class ListFormats
        {
            public string ItemFormat { get; set; }
            public string ListFormat { get; set; }
        }

        private static readonly IDictionary<ListType, ListFormats> Formatters = new Dictionary<ListType, ListFormats>();

        static ListFormatter()
        {
            Formatters.Add(ListType.Ordered, new ListFormats { ItemFormat = "<li>{0}</li>", ListFormat = "<ol>{0}</ol>" });
            Formatters.Add(ListType.Unordered, new ListFormats { ItemFormat = "<li>{0}</li>", ListFormat = "<ul>{0}</ul>" });
            Formatters.Add(ListType.TableCell, new ListFormats { ItemFormat = "<td>{0}</td>", ListFormat = "{0}" });
            Formatters.Add(ListType.TableRow, new ListFormats { ItemFormat = "<tr>{0}</tr>", ListFormat = "<table>{0}<table>" });
        }

        public static string ToFormattedList<T>(this IEnumerable<T> items, ListType type)
        {
            return FormattedList(items, type);
        }

        public static string ToFormattedList<T>(this IEnumerable<T> items, ListType type, Func<T, object> toString)
        {
            return FormattedList(items, type, toString);
        }

        public static string ToFormattedList<T>(this IEnumerable<T> items, ListType type, string format, params Func<T, object>[] toString)
        {
            return FormattedList(items, type, format, toString);
        }

        public static string FormattedList<T>(IEnumerable<T> items, ListType type)
        {
            return FormattedList(items, type, s => s.ToString());
        }

        public static string FormattedList<T>(IEnumerable<T> items, ListType type, Func<T, object> toString)
        {
            var listFormat = Formatters[type].ListFormat;
            var itemFormat = Formatters[type].ItemFormat;
            var itemsProjected = items.Select(item => string.Format(itemFormat, toString(item)));

            return string.Format(listFormat, string.Join(string.Empty, itemsProjected.ToArray()));
        }

        public static string FormattedList<T>(IEnumerable<T> items, ListType type, string format, params Func<T, object>[] toStrings)
        {
            var listFormat = Formatters[type].ListFormat;
            var itemFormat = Formatters[type].ItemFormat;

            var sb = new StringBuilder();

            foreach (var item in items)
                sb.AppendFormat(itemFormat, InvokeOnItem(item, format, toStrings));

            return string.Format(listFormat, sb);
        }

        public static string InvokeOnItem<T>(T item, string format, Func<T, object>[] toStrings)
        {
            var projected = new object[toStrings.Length];
            for (var i = 0; i < projected.Length; i++)
                projected[i] = toStrings[i].Invoke(item);

            return string.Format(format, projected);
        }
    }

HTML Output Abstraction and SubSonic

mxmissile — Wed, 31 Oct 2007 21:50:00 GMT

Jason has a posted a good read on the topic here.

On the topic of SS, I'm still on the fence. I grew up with WORM and have since migrated to NHibernate. I'm just not sure about the "Generate my domain from the database schema." idea. Unfortunately I mostly work with an older legacy db where I can't really redefine the schema (legacy apps are still in use) to match my domain model. Using a mapping file based mapper allow me to use my own naming convention versus a convention created 10+ years ago. With new projects I would *never* let my db schema dictate my domain, its not worth the stranglehold, but I cant start from scratch all the time.

To much comment FUD is going around right now. Stop it please! TDD is still possible with the Express versions of VS.NET! TestDriven.Net is *Not* required to utilize TDD. For example: NUnit is just one of the many tools that work just fine alongside Express. Maybe not as convenient, but it works just the same. I dont like it when people act like this is the end of TDD using Express.

...must get the green light!
