diffoscope will try to get to the bottom of what makes files or
|
||||
directories different. It will recursively unpack archives of many
|
||||
kinds and transform various binary formats into more human readable
|
||||
form to compare them.
|
||||
|
||||
|
||||
Mandatory Dependencies
|
||||
|
||||
Both python-magic and python-libarchive-c must be built with python3
|
||||
support, for example
|
||||
|
||||
PYTHON3=yes ./python-magic.SlackBuild
|
||||
PYTHON3=yes ./python-libarchive-c.SlackBuild
|
||||
|
||||
|
||||
Optional Dependencies
|
||||
|
||||
argcomplete (for argument completion)
|
||||
colord (for comparing images)
|
||||
colordiff (for comparing images)
|
||||
fontforge (for comparing font files)
|
||||
fpc (for Pascal support)
|
||||
ghc (for Haskell support)
|
||||
graphviz (for comparing images)
|
||||
jdk (for Java support)
|
||||
mono (for Mono support)
|
||||
pdftk (for comparing pdf documents)
|
||||
sng (for comparing images)
|
||||
tlsh (for fuzzy matching -- must build tlsh with 'PYTHON3=yes')

.SH DESCRIPTION
|
||||
.sp
|
||||
diffoscope will try to get to the bottom of what makes files or
|
||||
directories different. It will recursively unpack archives of many kinds
|
||||
and transform various binary formats into more human readable form to
|
||||
compare them. It can compare two tarballs, ISO images, or PDF just as
|
||||
easily.
|
||||
.sp
|
||||
It can be scripted through error codes, and a report can be produced
|
||||
with the detected differences. The report can be text or HTML.
|
||||
When no type of report has been selected, diffoscope defaults
|
||||
to write a text report on the standard output.
|
||||
.sp
|
||||
diffoscope is developed as part of the “reproducible builds” Debian
|
||||
project and was formerly known as “debbindiff”.

# HOW TO EDIT THIS FILE:
|
||||
# The "handy ruler" below makes it easier to edit a package description.
|
||||
# Line up the first '|' above the ':' following the base package name, and
|
||||
# the '|' on the right side marks the last column you can put a character in.
|
||||
# You must make exactly 11 lines for the formatting to be correct. It's also
|
||||
# customary to leave one space after the ':' except on otherwise blank lines.
