> Transforms CPX (JSX like syntax) into asm-dom Virtual DOM

![Preview](preview.jpeg)

## Motivation

[asm-dom](https://github.com/mbasso/asm-dom) Virtual DOM is a little bit verbose to write, we need a lot, not to much readable, lines of code to create a view. In addition we have to convert some types, merge attributes, props and do other stuff like that every time. For this reason we have decided to create `gccx`, a parser that allows us to write a new simple syntax. We will call this syntax `CPX`, it is based on [JSX](https://facebook.github.io/jsx/) but it has some differences. Basically `gccx` will transform this syntax into standard C++. In this way we can write files that appear very similar to HTML and can be written and read easily.

## Installation

You can install gccx using [npm](https://www.npmjs.com/package/gccx):

```bash
npm install --save-dev gccx
```

or, if you prefer, you can install gccx globally with:

```bash
npm install -g gccx
```

## Usage

Once you have installed gccx, you can use it from the command line or from javascript. Here is an example of both:

```bash
gccx src --output dist --watch
```

supposing a CommonJS environment, you can import gccx in this way and immediately use it with no configuration.

```js
import gccx from 'gccx';

const code = `
#include "../asm-dom/asm-dom.hpp"
#include
#include

using namespace asmdom;

int main() {
VNode* vnode =

Hello world!

;

patch(
emscripten::val::global("document").call(
"getElementById",
std::string("root")
),
vnode
);

return 0;
};
`;

const compiled = gccx.parse(code); // compiled code as string
```

## Examples

Examples are available in the [examples folder](https://github.com/mbasso/gccx/blob/master/examples). You will find examples of both, cli and javascript api usage.
