math environment is not marked up properly

[ouboub]

Hi

thanks for the fix. I pulled and reinstalled. I still think that the use of \begin{math} \end{math} is useful instead of ()

1. If I quickly want to change in a region from {equation} to {math} the query replace function is easier.
2. Sometimes people tend to have even longer latex constructs inline, then \begin{math} \end{math} improves the display.

Be it as it may I see quite a difference when using

alt.tex

\documentclass[12pt]{article}
\begin{document}
\(  \int f dx =0\)
\end{document}

new.tex

\documentclass[12pt]{article}
\begin{document}
\begin{equation}
  \int f dx =0
\end{equation}
\end{document}

Compared to having the old file as

old.tex

\documentclass[12pt]{article}
\begin{document}
\begin{math}
  \int f dx =0
\end{math}
\end{document}

I run

/usr/local/bin/latexdiff --math-markup=3 --driver=pdftex alt.tex new.tex > diff1.tex

and

/usr/local/bin/latexdiff --math-markup=3 --driver=pdftex old.tex new.tex > diff2.tex

And

/usr/local/bin/latexdiff --math-markup=1 --driver=pdftex alt.tex new.tex > diff10.tex

/usr/local/bin/latexdiff --math-markup=1 --driver=pdftex old.tex new.tex > diff20.tex

I attach the pdfs

Frankly in my view, ( ) is treated correctly but \begin{math}\end{math} no.

So if you could deal with that case I would appreciate this

regards diff1.pdf

diff2.pdf diff10.pdf diff20.pdf
