A New Language In C#

[jas0n23]

Hi All, I was wondering if it would at all be possible to create my own very small and simple programming language using C# Express Edition? And how one might go about doing so? I'd appreciate any help I can get on this. Thanks in advance :-) j.t.

Basically you will need to learn assembly language i.e. how an executable is created Then you would need to parse you language and produce your assembly code based on the parsed values Quite a simple theory really :P

You could always take a look at developing a DLR language (Dynamic Language Runtime). Take a look here[^] for a marketing type overview, and here[^] for more detail.

What you will need to do is create a program that will take in source code and emit object code. The source code will be written in your language; the object code be targeted at some machine. So it will either be machine code, aimed at a particular CPU, or byte code that runs on some virtual machine (e.g. the CLR in .Net or Java in a JVM). Effectively this means you have to write a compiler (or interpreter) in C#. This is not a trivial task. You might try looking at this book: Compilers: Principles, Techniques, and Tools Alfred V.

Or it could be an interpreted language and maybe not general-purpose.

Possible, yes. I've written a very simple interpreted scripting language for a very specific purpose; automating a telnet session. Do you have a particular need? Or just a curiosity? See also this[^] article.

I took a few minutes and made a programming language. Create a console application (named GuffaProgrammingLanguage of course), and put this in the Main method:

static void Main(string[] args) {
foreach (string line in File.ReadAllLines(args[0]+".gpl")) {
switch (line.Substring(0,Math.Min(line.Length,4))) {
case "out ": Console.WriteLine(line.Substring(4)); break;
case "time": Console.WriteLine(DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")); break;
case "end.": return;
default: Console.WriteLine("Syntax error."); return;
}
}
}

Create a text file in the bin folder named test.gpl with this content:

out Hello
out World!
time
end.

Open a console window and go to the bin folder, start the program with GuffaProgrammingLanguage test and you get an amazing result like this:

Hello
World!

Well, it's just out of plain curiosity and wanting to learn that's all. :-)
