Is there any way to highlight certain rows in dump results

sgmoore · June 2020

Just wondering if there is any way to highlight particular rows when dumping results.

Currently I add an dummy column and Util.RawHtml to colour something conditionally , eg to highlight negative values, I use something like

(from r in query
select new
{
    _ = r.Value < 0
    ? Util.RawHtml(new XElement("div", new XAttribute("style", $"color: red;"), ">>>>"))
    : Util.RawHtml(""),
   r.Name,
   r.Value,
   ...
 }).Dump();

Was wondering if there was something better that highlights the whole row. (other than repeating the same trick for every column) ?

In the next build, you'll be able to do this:

from file in new DirectoryInfo (Util.LINQPadFolder).GetFiles()
select Util.HighlightIf (
    file.Extension == ".exe",
    new
    {
        file.Name,
        file.Length,
        file.LastWriteTime
    })

and this:

from file in new DirectoryInfo (Util.LINQPadFolder).GetFiles()
select new
{
    Name = Util.Highlight (file.Name,
        file.Extension == ".exe" ? "yellow" :
        file.Extension == ".dll" ? "lightgreen" :
        null),  // null = no highlight
    file.Length,
    file.LastWriteTime
};

Just got the latest build and this works great.

Thank you very much.
