So I've found that VB syntax highlighting is broken in version 1.3
of BlogEngine.Net. If you add some VB code to a post like this:
[ code:vb ]
Imports System
Imports System.Data
Imports System.Math
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper
Imports Microsoft.SqlServer.Dts.Runtime.Wrapper
Imports System.Xml
Imports System.IO
Imports System.Reflection
Public Class ScriptMain
Inherits UserComponent
Dim sw As StreamWriter
Dim xWriter As XmlTextWriter
Dim rowName As String
[ /code ]
You get output like this:
Nice! So after some hunting through CodeFormatter.cs it looks like an
HTML decode has been left out entirely. This is strange because all the
other supported languages c#, javascript etc have the correct call to
HtmlDecode. I'm guessing it's a genuine oversight. After editing, my
CodeFormatter.cs looks like this around line 129:
private string Highlight(HighlightOptions options, string text)
{
switch (options.Language)
{
case "c#":
CSharpFormat csf = new CSharpFormat();
csf.LineNumbers = options.DisplayLineNumbers;
csf.Alternate = options.AlternateLineNumbers;
return HttpContext.Current.Server.HtmlDecode(
csf.FormatCode(text));
case "vb":
VisualBasicFormat vbf = new VisualBasicFormat();
vbf.LineNumbers = options.DisplayLineNumbers;
vbf.Alternate = options.AlternateLineNumbers;
//Jimmy:call to HtmlDecode has been left out in v1.3
//return vbf.FormatCode(text);
return HttpContext.Current.Server.HtmlDecode(
vbf.FormatCode(text));
...
}
}
I re-compiled and everything was dandy. Hooray for open source.
