How to convert tabbed tree to JSON in JavaScript?

Question

I was looking for an answer, but I think this is some kind of strange question. How to convert to a text file using tabs for interval, this:

parent child child parent child grandchild grandhcild 

to

 { "name" : "parent", "children" : [ {"name" : "child"}, {"name" : "child"}, ] }, { "name" : "parent", "children" : [ { "name" : "child", "children" : [ {"name" : "grandchild"}, {"name" : "grandchild"}, {"name" : "grandchild"}, ] }, ] } 

JSON is probably not perfect, but hopefully makes my conclusion clear.

Answer 1

I just implemented this function for tabdown markup language - it does exactly what you were looking for, https://github.com/antyakushev/tabdown

Usage is quite simple:

 var lines = data.toString().split('\n'); var tree = tabdown.parse(lines); console.log(tree.toString()); 

You can also use the parsing function outside node.js, it does not depend on any modules.
