git diff --word-diff You’re completely right, as does wdiff() with some post processing. I know, but the main drive for me to develop this was to come up with something that doesn’t require (especially non-technical) users to (sudo/brew/xcode) install anything additional to what’s already available on any unix(-like) platform. (Admitted: except for wkhtmltopdf, but that’s not essential to produce PDF - as this can also be done from the browser.)
