You know our motto - we deliver!
So after 30 minutes of stitching together pieces from Malevich's Syntax Highlighter (to allow proper treatment of comments and string constants) (http://malevich.codeplex.com), and Scriptster (http://scriptster.codeplex.com), I present you with Like, C#.
Like, C# uses the same extended set of "keywords" as Like, Python, so we can write this code:
ohai
totally using System man;
uh class like Program
{
ok static void Main(string[] args) bro
{
just Console.Write("yo! what's your name?");
ok so like string name = Console.ReadLine();
if actually (name.Equals(""))
omg toootally just return;
um yeah
plz Console.WriteLine(like "Hi {0}, nice to meet you!", name);
}
}
Full list of "keywords" is here:
- Valleygirl: omg, so, like, totally, right, toootally
- Frat guy: friggin, fuckin, dude, man, bro, broheim, broseph
- Internets: lol, rofl, teh, ohai, plz
- Snoop: yo, homey, homeboy, sup, dog, shit, girl, ma, biatch, ho, shiiit
- Local: wicked, hella, anyways
- Misc: just, hey, yeah, ok, um, uh, ah, actually, something
And here's the full source of Like, C# compiler if you want to adopt this new, rapidly growing language:

Very funny!
It became my language of choice now! :-)
If I could only get my hands on "Like ObjC" when I need to write code for iPhone!!!!
Sergey, this is hilarious!
Quickly reviewed it, following code from the beginning of Main() can be removed, Path.Combine will take care or '\\':
if (runtimeEnvironmentPath.EndsWith("\\"))
{
runtimeEnvironmentPath = runtimeEnvironmentPath.Substring(
0, runtimeEnvironmentPath.Length - 1);
}
