Blogging C # 3.0 Syntax Highlighting

I have plans to write a series of programming articles. There will be many examples of C # code. And for the code to be read, it must be highlighted.

But syntax highlighting disappears when you paste code into a blog. You need to use special programs to generate HTML with equivalent highlighting. I know about two such projects - Ookii.FormatC and Source Code Highlighter .

However, the functionality of both of them was not enough for me. I needed the ability to publish in LJ and on Habré (that is, without using css) plus LINQ highlighting. I decided to modify Ookii.FormatC and wrote my syntax highlighter.



Binary: Syntax Highlighter.rar
Sources: SyntaxHighlighter.src.rar
Requirements: Installed .NET Framework 3.5 SP1 (maybe lower, did not check)

Example:

using System;
// A single line comment starting at the beginning of the line
using System.IO;
/* A comment block starting at the beginning of the line */
using MyNamespace;

namespace CSharpTest
{
    // A comment containing what looks like a "string"
    // A comment containg /* what looks like */ a block comment
    /* A multiline comment
     * also containing a // regular comment
     * And containing what looks like a "string"
     */

    public class Program
    {
        ///

        /// An XML comment .
        ///

        public static void Main()
        {
            int Int; // case sensitive test
            int @int; // escaping test
            Console.WriteLine("A string \" \\\" hello \t\\");
            Console.WriteLine("A string containing what // looks like a comment."); // followed by a real comment
            Console.WriteLine(@"An @ string"" \"); /* and another comment */
            Console.WriteLine(@"Another @ string """"");
            Console.WriteLine("{0} {1} {2}", "more than one\\", /* embedded comment */ @"string on ""the same", "line");
#if PREPROCESSORTEST
            for( int x = 0; x < 10; ++x )
            {
                Console.WriteLine('x');
                Console.WriteLine('\'');
                Console.WriteLine('\\');
            }
#endif
        }

        public static void Linq()
        {
            IObservable> draggingEvent =
                from mouseLeftDownEvent in control.GetMouseLeftDown( )
                from mouseMoveEvent in control.GetMouseMove( ).Until( control.GetMouseLeftUp( ) )
                let comparer = new MouseEventComparer( mouseMoveEvent )
                group mouseMoveEvent by comparer into cluster
                select cluster;
        }
    }
}

Screenshot:

Differences from Source Code Highlighter

- LINQ syntax highlighting.
- Correct processing of lines and comments.
- Open Source.

Differences from Ookii.FormatC

- Does not use css and pre tag.
- Replaces leading spaces with nbsp.

Notes

I modified the Ookii.FormatC code exactly as much as I needed for the working C # 3.0 backlight in LJ and Habré. If the project proves to be in demand, perhaps I will:
- transfer the code to a normal host.
- I will be engaged in refactoring and code reorganization.
- I will complete the highlighting for other languages ​​supported by the Ookii.FormatC library (C #, Visual Basic, C ++, XML, HTML, Transact-SQL, PowerShell).
