/*
|
|
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:
|
|
< -> <
|
|
> -> >
|
|
& ->
|
|
