I did something similar a while back. It parsed a .ini that
contained default values and created a statically typed runtime
parser for the actual .ini file from it. It was fun, to see
that you can do that with D.


Yes. I use import('filename') to configure my application too. I 
have config.json, where I store standard application's file 
paths, options and so on. It's very handy compiler's feature

 Something like this

 string getVar(string fname,string var)(){

 Where you add your config dir(that contains shapes) file to
 dub's  stringImportPaths.
 How do you guys feel about this? Should we use something like
 json for config files?
