if the user is perlwise (and only then), my favourite option is to simply put the config-data as perl code in the config-file, like
"root" => "/path/to/root",
"filepath" => "/path/to/files",
"ftp_instances" =>
[
{
"sourcepath" => "/source/path/on/server",
"savepath" => "/save/files/here",
},
{
"sourcepath" => "/source/path/on/server",
"savepath" => "/save/files/here",
},
]
Then you can simply read the file, do
eval "%CFG = (" . readfile("cfg") . ");";
and you´re gone.
The benefit is that you can safely bring in all kind of difficult data (newlines etc.), and you can use an idiom you are pretty much used to.
