latex diff old with new

latex-diff

Create a diff of the new PDF to the old PDF. This flattens the LaTeX structure before diff'ng the contents.

    $ latexdiff --flatten old.tex new.tex > diff.tex
    $ latexmk -pvc -f -pdf -quiet diff.tex
    
Environments can also be ignored using the config command

    $ latexdiff --config="PICTUREENV=(?:picture|DIFnomarkup|figure|lstlisting)[\w\d*@]*” \
                --flatten old.tex new.tex > diff.tex
    $ latexmk -pvc -f -pdf -quiet diff.tex
