problem when converting from latex to markdown

[Cesar Romani]

What's wrong with the following latex code?

--------------------
\documentclass[10pt]{book}
\usepackage[utf8]{inputenc}

\renewcommand\maketitle{\begin{titlepage}%
   \enlargethispage{1in}
   \let\footnotesize\small
     \let\footnoterule\relax
     \parindent\z@
     \vspace*{-1in}
   \begin{center}%
     \vspace{\stretch{3}}
   {\Huge\noindent\textbf{\@title}\par}%
   \vspace{\stretch{1.5}}
   %{\Large\textbf{\@author}
   {\LARGE\textbf{\@author}\par}%
       \vspace{\stretch{2}}
       {\Large\@advisor\par}%
     \vspace{\stretch{4}}
     {\Large 2011}
     \vspace{\stretch{0.5}}
     \end{center}
     \end{titlepage}%
       \setcounter{footnote}{0}%
}

\begin{document}
Hola
\end{document}
--------------------

After running:
pandoc -o test.txt test.tex
I get:

--------------------
pandoc:
Error:
"source" (line 1, column 1):
unexpected '\\'
expecting "%", new-line, "begin", "}", "\\}", "\\{", "\\\\", "{", 
letter, "-", "``", "`", "'", "~", "$$", "$", "^", "_", "^^", "]", "#", 
"&" or end of input
--------------------

I don't have any clue what that means.

Many thanks in advance,

I had a similar problem with \vspace a while back. It failed if it was at the end of a line without a blank line following. Pandoc 1.9.1.1 fixed that particular problem for me.

I'm using pandoc 1.9.2 on Windows 7.

Well, LaTeX doesn't choke on it, so it's probably fine.

Pandoc is telling you here that the error is on the first line and the
first character.

> unexpected '\\'

It sees a backslash (I'm assuming it's being escaped here)...

...though it's expecting one of the above.

My first idea was that Pandoc wasn't expecting LaTeX input (I don't know if
Pandoc deduces the input format from the ending), but doing 

pandoc -r latex -o text.txt test.tex

produces the same error. So this looks like a bug to me. It's weird,
though, that the presence of the \newcommand on line three should trigger a
bug on line 1...

Anyways, I'm using Pandoc on Linux and I get the same problem.

pandoc seems to be confused because you don't use braces around 
\maketitle. The following works for me:

     \renewcommand{\maketitle}{\begin{titlepage}%

You don't need to put braces around \maketitle. If I delete the line
beginning with %, it works and you don't have braces around \maketitle.

What line beginning with a %? And if the code shared with you works,
are you now just asking a theoretical question?

I've uploaded a new version of texmath that can parse the
original \renewcommand.  If you recompile pandoc against the
latest texmath from HackageDB, you shouldn't need the braces.

I've downloaded the last version of texmath. How do I recompile pandoc
against it?

cabal update && cabal install --reinstall texmath && cabal install --reinstall pandoc
