5.2 Differences with wdiff
Even if mdiff is meant to fully support wdiff, options have
been shuffled around so mdiff could better merge both diff
and wdiff options in a common scheme. diff habits were
almost always favored in this option reorganisation.
wdiff2 is now a mere front-end to mdiff that only
rewrites the options. The following notes apply.
- Some options are just transmitted unchanged, these are -1,
-2, -3 and -i.
- Option -c also gets turned into -i, to be compatible with
wdiff versions up to ‘0.4’.
- Simple option -a in wdiff becomes -A in mdiff,
-l becomes -k, -n becomes -m, -p becomes
-o, -s becomes -v and -t becomes -z.
- Options introducing strings, which are -w, -x, -y
and -z in wdiff, respectively become -Y, -Z,
-Q and -R in mdiff.
- Options -C, -h and -v are processed directly by
wdiff and are not transmitted to mdiff.
- Further, the -C option of wdiff has no equivalent in
- A new option -q inhibits the message which explains how mdiff
might have been directly called.
- The option --diff-input (-d) from wdiff
isn't supported by wdiff2 (yet).
