Hello!
There is one useful feature in Catalyst::Plugin::ConfigLoader - substitutions before parsing config:
http://search.cpan.org/~bricas/Catalyst-Plugin-ConfigLoader-0.30/lib/Cataly…
Sometimes it's comfortably to use paths relative to 'appdir' or 'public'.
Cwd (current working directory) depends on your setup (mod_per,plack,etc.)
In my case (plackup under supervise) cwd is under service (daemontools specific) directory.
I have adjusted Dancer::Config slightly:

- eval { $config = YAML::LoadFile($file) };

+ open my $fh, $file or

+
+ eval { $config = YAML::Load($yaml) };
if (my $err = $@ || (!$config)) {
confess "Unable to parse the configuration file: $file: $@";
}
This little patch allowed me to use relative paths in config.yml without worry
about my top-level setup:
engines:
xslate:
cache_dir: '__setting(appdir)__/var/xslate'
path: [ '/','__setting(views)__' ]
photos:
basedir: '__setting(appdir)__/photos'
What do you think about inclusion this functionality in Dancer core?
