config file modules confusion

Hello
I searched cpan and was overwhelmed by the number of modules
available.

I want a config module that can do updates well, preserving formats of
original file, preserving blank lines, comments, etc. which one should
I use..?

Config::General, Config::Simple, Config::Inifiles, just to name a
few..

Thanks!
Jim

I had used Config::Simple which I think is the right module for parsing a config file.

Yes, there are many Config:: files around. A prominent Israeli Perl Monger has
given an entertaining presentation on this subject in a Tel Aviv meeting
comparing it to Alenby Street in Tel Aviv (the reference would be lost to non-
locals and was not obvious to us when we heard of it.). The slides are not
online unfortunately.

I believe (but am not entirely sure) that Config::IniFiles goes to great
lengths to make sure comments and possibly also white space are preserved and
can even be manipulated or changed. It should also preserve the order of the
keys in the file, assuming there are no duplicate keys.

I should note that I'm the current Config-Inifiles maintainer, and have done
quite a lot of work on it recently, that involved modernising the test suite's
code, applying patches, etc. The internals of Config-IniFiles are somewhat
messy and suffer from some ancient Perl issues, and the test suite may not be
comprehensive, but it should work fine for most people, and we'll handle any
issue reported on the rt.cpan.org bug tracker given at least a reproducible
test case.

Also see:

http://blogs.perl.org/users/steven_haryanto/2010/11/comparis on-of-ini-format-
modules-on-cpan.html

(short URL - http://xrl.us/bihrdb ).

Of course, don't take my word for it, and write some test cases to see that
everything works fine. This is assuming you won't find the INI-file format
(which is limited to two levels) too restrictive.

Good luck!
