This is a simple and lightweight library to compile snippets of LaTeX code into a document object so you can do your own converting to your format.
// each of these namespaces are increasing levels of abstraction
using LaTeX.Net.Lexing;
using LaTeX.Net.Parsing;
using LaTeX.Net.Parsing.Document;
// the original LaTeX code
string latex = """
Good morning \textbf{Santa Maria, the \textit{heart of Rio Grande}}, today is \textit{25C}!
""";
// this will convert the LaTeX code into a list of tokens
Scanner scanner = new(latex);
List<Token> tokens = scanner.ScanTokens();
// here we parse these tokens and create a abstract syntax tree, you can use
// this, but it will be a little harder
Parser parser = new(tokens);
SyntaxTree tree = parser.Parse();
// the last abstraction, with the document object you can do whatever you want
LatexDocument document = parser.GetDocument(tree);
