Possibility of aligning ":" in output

[fedormsv]

To use json files in a context where human readability makes sense, it's nice to have "name : value" pairs aligned on ":" at least within one object.

How about those nested JSON objects, especially long keys?
For example,

{
   ...
   {
      ...
         {
             “long key............................” : ...
             "abc"                               : ...
         }
   }
}

Under some cases, it will make the file's row length even longer.
I think it is sufficiently friendly for readability when we use writer with current indent setting.

What's more, it means that we should calculate the longest indent first in json object, and then insert some blank into other members to make name : value paris aligned on :.

Idea is not on changing names, but to add extra spaces between name closing quote and :. Within one object can be enough. We implemented it as writer builder option, harmless if not changed I believe.

I konw this idea is not on changing names, what I means is that adding extra spaces would make the file's row length even longer.
We already have indentations in every level, IMO, it is sufficiently friendly.
