The Web is all the rage these days, and everyone knows that in order to write a good webapp, you need to use a framework. One of the popular options these days is React, which comes with its own syntactic extension for an XML-like syntax in JavaScript.
But who wants to write JavaScript, right? It's all slow and sluggish. Naturally, we want to write our webapp in a language that's performant and close to the metal, so C++ is the clear choice. But, I hear you wonder, how do we express XML trees in C++? If only we had an extension letting us embed an XML-like syntax in our C++ source code.
Wait no more: enter C+X. It's like JSX but for C++. Sorta.
CPX render() {
return (
_ <html>
_ <head>
_ <title>"Hello"<-title>
_ <-head>
_ <body>
_ <p>"Hello world!"<-p>
_ <-body>
_ <-html>
_
);
}
int main(int argc, char *argv[]) {
std::cout << render().str() << std::endl;
return 0;
}-
What's with the underscores?
That's how you signal embedded C+X syntax to the compiler.

Wait a minute, doesn't an ending tag usually look like
</p>?Correct! For technical reasons, though, we have opted for
<-p>instead. Surely this minor syntactic detail shouldn't matter much? -
Is this a joke?
Maybe.
- C++ ﹤HTML﹥ -- similar goal, different approach. Inspired this project, and predates it by exactly a year!
