Map join doesn't getting applied to the levels #23

Closed dezashibi closed 1 year ago

dezashibi commented 1 year ago

consider an Object is Dic<Var> that naturally can have other Objects or Array<Object> as well inside when I use join on the top level and let's say I want ", " and " : " it won't make any difference to the nested objects and it will use the default "," and "=" instead.

P.S. to print out the Object I can use Json::encode which is fine, in some cases join characters might be completely different based on usecases.

Dic::join() only works on one level (key: value, ...). The Dic class knows nothing about nesting. join() converts all keys and values to String, if possible. A value of type Var is just converted to String with its toString() method that does a simple serialization, always using ',', '=' for objects.

Json::encode() and Xdl::encode() are better ways to serialize nested objects, but they have a fixed syntax. Making .join() smarter for the Dic<Var> case would be too complicated. You could look at the Var::toString() function to make new configurable function out of the library.

I checked, yes might make it complicated, I will though try to see if I can do something about it and if the solution was good enough to be put in the ASL I will open pull request. thanks.
