latexdiff is a Perl script and requires an installation of Perl 5.8 or higher.
If you are a Windows user you will have to go through the following setup to get latexdiff working on your machine:
- install Perl & latexdiff:
ActiveState | Secure & Reproducible Python Runtimes Click Get Started
Click Sign up with Github
Input latexdiff can verify whether your latexdiff is successfully installed. If it is not successfully installed, the last line (2 and only 2...) will appear.
- enjoy latexdiff!
Next, put the original manuscripe(such as origin.tex) and the modified manuscripe(such as modify.tex) in the same folder, and switch the path of CMD to this folder
CD d:20210602 (cd+ file path)
Then enter the command: (diff.tex can be named casually)
latexdiff origin.tex modify.tex >diff.tex
Look!
