/*
HtmlTextStream is used as a buffer for creating a html page
By default all operators<< escape its string arguments. If you don't want
to escape an argument you should use a helper function R() (raw argument)
note: you have to define the function yourself, we do not provide it
because such a short name would make a mess in namespaces
sample:
create a helper function R as follows:
template<class RawType>
HtmlTextStream::RawText<RawType> R(const RawType & par)
{
return HtmlTextStream::RawText<RawType>(par);
}
now you can use HtmlTextStream in an easy way:
HtmlTextStream page;
std::string key = "some <b>string</b>";
page << key << R("<h2>html goes here</h2>");
only html tags "<b>" and "</b>" will be correctly escaped
currently following characters are escaped:
< -> &lt;
> -> &gt;
& -> &nbsp;
" -> &quot;
' -> &#39; (it is "&apos;" but IE8 has a problem with &apos;)
10 -> &#10;
13 -> &#13;
