|

TexTextStream is used as a buffer for creating a TeX input
|
|
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>
|
|
TexTextStream::RawText<RawType> R(const RawType & par)
|
|
{
|
|
return TexTextStream::RawText<RawType>(par);
|
|
}
|
|
|
|
now you can use TexTextStream in an easy way:
|
|
TexTextStream page;
|
|
std::string key = "some text with $# ^{} tex \\ special characters";
|
|
page << key << R("\\def\\myfun{...}");
|
|
|
|
everything in 'key' is property escaped for using with TeX
