Announcing Config::ZOMG

For a while now I've wanted to tear Config::JFDI up. Since I first used it it's always been too heavy and had too many little weird things. Well, I did that last night and it ended up getting three times faster! I've released the fork as Config::ZOMG (I considered GTFO and STFU, but thought better of it.)

For the most part it's the same as Config::JFDI of course, but basically what I did was remove the substitution and install_accessor features, removed isa checks, and switched from Any::Moose to Moo with inlined defaults. One other major thing I did was took out the superfluous API bits. I see no reason for $config->load, $config->get, and $config->config to do the exact same thing, so now you just get load.

If you are unfamiliar with all of this basically what this means is that you can create a file myapp.json and myapp_local.json and it will load both of those and merge them, with local winning. Also it will work with almost any other file format out there (yaml, perl, Config::General, etc) supported but Config::Any.

Here's how to use it:

use Config::ZOMG;
my $config_hash = Config::ZOMG->open( path => './myapp' );

# or if you want to keep the object around (maybe to use the reload feature)

my $config = Config::ZOMG->new( path => './myapp' );
my $config_hash = $config->load;

Anyway, if you are interested make sure to check out the docs, since there are actually more features as is, but my usage is basically as above.

I have some plans for the future that I think are exciting, like instead of just a universal config file reader, a universal writer as well. I'll keep you all posted.

Oh and if you are interested in a tiny, unscientific benchmark, check this out:

helena [6555] ~ $ time perl -MConfig::JFDI -E'Config::JFDI->open(path => "./dbic")'
perl -MConfig::JFDI -E'Config::JFDI->open(path => "./dbic")'  0.53s user 0.05s system 99% cpu 0.583 total

helena [6556] ~ $ time perl -MConfig::JFDI -E'Config::JFDI->open(path => "./dbic")'

perl -MConfig::ZOMG -E'Config::ZOMG->open(path => "./dbic");'  0.18s user 0.01s system 95% cpu 0.201 total

helena [6557] ~ $ time perl -MConfig::ZOMG -E'Config::ZOMG->open(path => "./dbic");'
perl -MConfig::ZOMG -E'Config::ZOMG->open(path => "./dbic");'  0.16s user 0.02s system 96% cpu 0.183 total

helena [6557] ~ $ time perl -MConfig::ZOMG -E'Config::ZOMG->open(path => "./dbic");'
perl -MConfig::ZOMG -E'Config::ZOMG->open(path => "./dbic");'  0.15s user 0.03s system 97% cpu 0.180 total

and the file (dbic.json) looks like:

{
   "profile":"console",
   "log_sprintf": {
      "caller_depth":2,
      "caller_clan":"^Try::Tiny|^DBIx::Class|^Log::Sprintf",
      "format": "%l%n%m%n",
   },
   "no_repeats":1,
   "placeholder_surround":["\u001b[30;46m","\u001b[0m"]
}
