Allows inclusion of html pages inside C++ code
More and more applications use web-interfaces nowadays. Situations when HTML pages must be returned by C++ program become more common. But embedding pages inside a C++ source file as text strings is not HTML developer friendly, while having bunch of HTML pages with program distribution may be not a nice solution for small programs or programs that do not carry around resources.
html_inside_cpp allows you to embed HTML page in C++ source, still leaving the HTML page usable and modifiable by HTML developer.
Imagine that you have a small HTML file hello.html, that must be embedded inside C++ source file:
<html>
<head></head>
<body>Hello word!</body>
</html>
To do so, slightly modify hello.html:
<!--
HTML_HELPER
const char html_page[] = TO_STRING(
<!-- -->
<!DOCTYPE html>
<html>
<head></head>
<body>Hello word!</body>
</html>
<!-- ); // end of TO_STRING <!-- -->
now it is ready to be embedded into your main.cpp source file:
#include <iostream>
#include "html_begin.pp" // header from this repo
#include "hello.html" // your HTML file
#include "html_end.pp" // header from this repo
int main() {
std::cout << html_page; // outputs your HTML page content
}
Here is what will be outputted by running main.cpp:
<!-- --> <!DOCTYPE html> <html> <head></head> <body>Hello word!</body> </html> <!--
In your project you'll have main.cpp and hello.html files. And hello.html can be shown in browser and modified independently from main.cpp.
- In HTML lines must not start with
#. - JavaScript must use
/*and*/comments. - JavaScript comments will be totaly removed in C++ source.
- All the newlines will be romowed from HTML document that is embedded in C++ source (use
;in JavaScript!). \must be replaced with\\(beware JavaScript regex users!)- HTML page must start with:
<!-- HTML_HELPER const char html_page[] = TO_STRING( <!-- --> <!DOCTYPE html>.
