Util.RawHtml and whitespaces

RobertGiesecke

Hi guys,
It seems that Util.RawHtml will add formatting to the output of the provided XML.
The problem here is, that I want to display syntax highlighted code, which is contained in a <pre>. [1]
Because of the formatting, the output looks rather weird (the pre-tag will retain the whitespaces that were introduced by the XML formatting)
I would suggest to add an optional parameter to RawHtml, to tell LinqPad to use:

xml.ToString(SaveOptions.DisableFormatting)

Or simply always use SaveOptions.DisableFormatting for RawHtml.

btw, I am using the current Beta (4.42.01)

[1] If you found this thread searching for syntax highlighting in LinqPad, I am using ColorCode http://colorcode.codeplex.com/

Can you give an example?

btw, are you aware that LINQPad has a built-in feature for displaying syntax-colored text?

PanelManager.DisplaySyntaxColoredText ("var x = \"foo\"", SyntaxLanguageStyle.CSharp);

SyntaxLanguageStyle can be one of the following:

None, CSharp, VB, FSharp, SQL, ESQL, CSS, HTML, JavaScript, PowerShell, Python, XAML, XML

Hi Joe,
You can run this query and should see some whitespace before the text:

new{SomeProp=Util.RawHtml("<pre><span>Shouldn't have whitespace on the left</span></pre>")}

Oh and I know about PanelManager.DisplaySyntaxColoredText, but it doesn't put the text in the ordinary HTML-based output, but into extra "tabs".
Sometimes, I want to show some scripts in a table, and RawHtml is doing the job almost perfectly. :-)

OK: I'll get rid of the formatting in LINQPad's HTML output. I don't see why it's needed - it only adds bloat and people can use reformatting tools if they're interested in examining the source.

Cool, thx a lot! :-)

Thx Joe,
One tiny little problem still remains:
The overload of RawHtml, that takes a string does not preserve whitespaces.
When you run the following query, you should see that there is no whitespace between "blue" and "red".

Util.RawHtml(@<pre><span style='color:Blue;'>blue</span> <span style='color:Red;'>red</span></pre>)

When I change it to use the overload that takes an XElement (parsing it with LoadOptions.PreserveWhitespace), the output is as expected:

Util.RawHtml(XElement.Parse(@<pre><span style='color:Blue;'>blue</span> <span style='color:Red;'>red</span></pre>, LoadOptions.PreserveWhitespace))

I simply changed it in my utility library to use the XElement-overload, so I do not need that fix.
It isn't really obvious, though and the fix seems to be quite straight forward.

Thx for your work on this awesome tool.

Cheers,
Robert
