Text
Text is a programming language created by User:Smallhacker. Whilst not many people have heard of Text, almost all ASCII files, including readmes, and interpreted programming language source code files, are actually written in Text.
Description
All Text programs output their own source code, thus every program is a quine.
Despite the language being very young, there's already tons of interpreters for Text, perhaps the most famous of which is Notepad. On Unix-derived systems, the traditional interpreter is 'cat'.
The file extension for Text programs is .txt. However, many Text programs omit the file extension.
Some relatively recent Text interpreters, such as TextEdit on the Macintosh, add support for 2D graphics.
Given that books and paper are fully capable of executing Text programs, they're actually probably some the first computers ever invented.
Examples
Hello World
Hello World
Quine
Even a baby could write a quine.

Compilers
Here are a few compilers for Text:
echo - Present as a statement in some script language like Bash and Batch, executes a statement of a Text program
copy con - Present as a statement in Batch, executes a Text program written by the user in stdin and writes its output to a text file
type - Executes a Text program (from a source code file)
Even the recent Ideone.com online multiple language compiler can compile Text Programs.
Its example program is:
Charlie bit me!
And it provides an example stdin:
That really hurts!
The application returns the value:
Charlie bit me!
Development of a compiler
In fact it is really easy to make a Text compiler. Here are some examples. The first (made in Pascal) reads a Text statement and executes it. The second one (made in console VB.NET) reads from the command line a txt file and executes it (like type):
Pascal
program textcompiler; uses crt; var a:string; begin a:='Here is a sample Text statement' // read the Text statement write(a); // execute the Text program end.
VB.NET
Class TextCompiler Sub Main() Console.WriteLine(My.Computer.FileSystem.ReadAllText(Command())) 'executes the Text program inside a text file passed in the command line End Sub End Class
AWK

C
This is a version that reads from text files, not from the console.
#include <stdio.h> int main(int a, char *v[]) { FILE *f=fopen(v[1],"r"); char c; while((c=fgetc(f))!=EOF) putchar(c); }
Development environments
The most popular development environment for Text is named Notepad, and comes default with Windows. It is simple, yet powerful, compiling and running the program as you type it.
Other development environments for Text include Leafpad (Linux), Wordpad (Windows), Emacs (Cross-platform), and Vim (Cross-platform).
