Re: Document containing different text colours?

[John Kitchin <jkitchin@andrew.cmu.edu>]

This would not be too easy to achieve.

One way I can see it happening is if you keep your manuscript in a VC
system like git, and you tag the different draft versions. Then you use
the VC diff machinery to find the diffs between the versions, and
somehow use that to put color overlays or text properties.

latexdiff can do something like this but only for two versions, not
multiple versions. Even the fanciest of diff programs I think can only
deal with three files (versions).

You might find some insight at
https://github.com/jkitchin/scimax/blob/master/scimax-editmarks.org#from-git-diff.

this uses the scimax-editmarks package I have been working on, and uses wdiff
to markup the differences between two versions of a file in a git repo.

Looking back on this you should expect a rainbow soup of issues, for
example, how would you deal with text that has been deleted? or moved
around, or changed a few times between versions.

I am not sure it would be easy to figure out how to do this for multiple
versions.
