Example on how to use with LaTeX

[kpeeters]

Do you have a simple example on how you intend people to use TeX-- with LaTeX? Is the idea to overload the tex class similar to what you did with plain?

Is the idea to overload the tex class similar to what you did with plain?

Yes.

You will need to ensure that all of your LaTeX macro files are in your tex folder (or are found in your search_dir).

Any additional macro files needed by the application should be stored in the tex folder. Although, if they are in the search_dir directly, they will be found.

Afterward, it should as simple as preloading any packages your documents assume are already loaded, similar to what tex::plain’s constructor does withR"(\input plain)":

virtual void typeset(const std::string& filename, std::streambuf * resultbuf, const std::string& search_dir, const std::string& working_dir, std::ostream& output)
{
	input_path = search_dir;
	if (input_path.empty() == false and input_path.back() != '/')
		input_path.push_back('/');

	output_path = working_dir;
	if (output_path.empty() == false and output_path.back() != '/')
		output_path.push_back('/');

	input_stream = new std::stringstream; // will be closed as term_in
	output_stream = new std::iostream(output.rdbuf()); // will be closed as term_out

	if (resultbuf) {
		dvi_file = new std::stringstream;
		dvi_file->rdbuf(resultbuf);
	}

	tex::typeset({
		R"(\nonstopmode)", // omits all stops (\batchmode also omits terminal output)
		R"(\input plain)",
		R"(\input)", filename.c_str(),
		R"(\end)",
	});
}
