Raw output

More-or-less verbatim text can be printed to the output file. A single backslash is produced by a double backslash in the input file. Certain letters have special meanings when backslash-escaped, including ``\n'' (newline) and ``\t'' (TAB). Unlike L^ATEX, C++ does not require a space to separate an escape sequence from following text; the string ``\textwidth'' is read ``TABextwidth'' by the compiler.

As an application, a complete L^ATEX figure environment (with caption and label) can be produced by an ePiX file. Newlines must be added explicitly, and all printing statements must occur inside the call to main().

#include "epix.h"
using namespace ePiX;
using std::cout;      // C++'s output function

int main() 
{
  cout << "\\begin{figure}[hbt]\n";
  unitlength(...);    // picture, bounding_box, etc.
  begin();
  < ... ePiX commands ... >
  end();
  cout << "\\caption{A \\LaTeX\\ figure.}\n" // N.B. line con-
       << "\\label{fig:example}\n"           // tinues, no ";"
       << "\\end{figure}\n%%%%\n";           // LaTeX formatting
} // End of main()
