6 years ago I have this not published version of the file which handles bullet lists and numbered lists. Also subjections. I don't handle quotes yet. What I'd really like to add is footnotes.
That said, I don't have a good way to debug this. What I've done so far is develop via try and error with a very small doc file.
// Based on http://github.com/mangini/gdocs2md
function ConvertToSimpleLatex() {
var numChildren = DocumentApp.getActiveDocument().getActiveSection().getNumChildren();
var text = '';
var attachments = [];
var inItemize = false;
var inEnumerate = false;
// Walk through all the child elements of the doc.
for (var i = 9; i < numChildren; i++) { // 9 to skipe the firest 2 pages
var child = DocumentApp.getActiveDocument().getActiveSection().getChild(i);
var result = processParagraph(i, child);
if (result !== null) {
if (result && result.length > 0) {
if (starts(result, '{itemize}') || starts(result, '{enumerate}')) {
if (starts(result, '{itemize}')) {
line = result.substring(9);
if (!inItemize) {
text += '\\begin{itemize}\n'
inItemize = true;
}
text += '\\item ' + line
} else { // enumerate
line = result.substring(11);
if (!inEnumerate) {
text += '\\begin{enumerate}\n'
inEnumerate = true;
}
text += '\\item ' + line
}
} else {
if (inItemize) {
text += '\\end{itemize}\n'
inItemize = false;
}
if (inEnumerate) {
text += '\\end{enumerate}\n'
inEnumerate = false;
}
text += result
}
text += '\n';
}
} else {
text += '\n\n\\vspace{1cm}\n\n'
}
}

Hello,
I would be interested in improving gdocs2latex.gs to handle these situations: bullet lists, numbered lists, subsubsections, and quotes.
However, I'm not aware of how to easily debug the script and would need guidance in understanding the data structure element.
Thanks!
Hola,
Me interesaría mejorar gdocs2latex.gs para manejar estas situaciones: listas de viñetas, listas numeradas, subsecciones y citas.
Sin embargo, no estoy al tanto de cómo depurar fácilmente el script y necesitaría una guía para comprender el elemento de estructura de datos.
¡Gracias!
