Ever tried comparing MySQL's my.cnf from a Debian and a Gentoo machine
with diff(1) without going crazy?
diff(1) is an awesome tool, you use it (or similar implementations
like git diff, svn diff etc) every day when dealing with code.
But configuration files aren't code. Indentation often does not matter
(yeah, there is diff -w and yeah, people use YAML for configs), order
of settings does not matter and comments are just beautiful noise.
cfgdiff will try to parse your configuration files, fetching all the
relevant keys and values from them and then pretty-printing them in the
original format. These results are then diffed and the diff is shown to
you.
cfgdiff currently supports the following formats:
- INI using Python's ConfigParser library
- JSON using Python's JSON library
- YAML if the Python YAML library is installed
- XML if the Python lxml library is installed
