Often times, you may want to see changes between two latex files: let’s say old.tex and new.tex file.
There is a simple workaround that creates diff.tex file using latexdiff. I have tried to use texdiff and compiled using texshop but it spits lots of errors (protect/TLS ….).
Alternative is using latexdiff and it works like charm in my case. Locate two tex files in a folder and run the following command.
latexdiff old.tex new.tex > diff.tex
You should be able to compile diff.tex file if you can compile new.tex and old.tex files. The below is an example how it looks like.
Amazing idea with right people.
