[gentoo-user] print side-by-side diff w/ highlighting?

[Grant Edwards]

I'm trying to find some sort of side-by-side diff that will
highlight the differences and produce pritable output (e.g.
html or postscript).

I've found tools to "colorize" diff output, but not for
side-by-side.  I've found tools to display side-by-side
differences with hightlights, but they can't print.

How do I print side-by-side diff with changes hightlighted
(e.g. bold or colored)?

To be a bit more specific, I've found "colordiff" but it
highlights entire lines rather than just changes, and it
doesn't product printable output.

redirect "diff -y" to printer?

In diffs, changes are always lines.  It's line based, not character based.

I want changes highlighted.  All diff -y does is mark which
lines have changed.

Which is why it does't meet my requirements.  I want the
changes hightlighted.  I've found tons of utilties (like meld)
that do that on-screen, but I haven't found any that print.

FWIW, I couldn't find anything, so I wrote my own utility. It's
not very general purpose since it assumes that there've been
only changed lines and no lines inserted/deleted.  But, it
works for my use-case and it generates either HTML or
postscript output. :)

Emacs has ediff-files and ediff-buffers commands which colorize the
individual changes within each line, altho they seem to be word based
rather than character, such that if only a single character is
different, it will highlight the entire word containing that character.

I do not know how to print from it, however; it is interactive.  There
may be some obscure command, but since I haven't had or used a
functioning printer in years, I don't know.
