#38 Diff of tar/ zip archives

[Keith Hyland]

Any chance of a feature to compare certain archive
files such as tar/ zip/ jar etc.

Obviously this can be done by expanding the archive and
running xxdiff on the dirs, but it would be nice not to
have to do this.

hi khylo

this feature is unlilkely to happen for the following reasons:

- xxdiff is deliberately written to incorporate well within
wrappers scripts which would invoke it to do what you
mention; tihs is an approach that has worked well in the
past, for many other uses;

- there are too many potential formats to support

so i'll keep it low on the priority list. what is more
likely to happen, it that i would write a pytohn script to
wrap exactly that functionality (perhaps using "atool" to
handle the various formats).
