Handle arrays, functions, and custom string for replacement

[risq]

Hi, First, thank you for the lib, it has been very useful for some projects !

I had to edit it a little to make it fit to my needs, so I thought I could share it. Here are the changes :

• handles function values
• displays the type of the pruned object instead of -pruned- : Object (pruned), Array (pruned), Function (pruned).
• allows to pass a custom string replacement for pruned values

Here is an example :

var obj = {
  key1: "111",
  key2: {
    arrayValue: [1, 2, 3],
    intValue: 1,
    objectValue: {
      key: "val",
    }
  },
  key3: function() {
    return 'ok';
  }
}

var pruned = JSON.parse(prune(obj, 2, 50));

Before:

pruned = {
  key1: "111",
  key2: {
    arrayValue: "-pruned-",
    intValue: 1,
    objectValue: "-pruned-"
  }
}

After:

pruned = {
  key1: "111",
  key2: {
    arrayValue: "Array (pruned)",
    intValue: 1,
    objectValue: "Object (pruned)"
  },
  key3: "Function (pruned)"
}

Using a custom string:

var pruned = JSON.parse(prune(obj, 2, 50, '...'));

pruned = {
  key1: "111",
  key2: {
    arrayValue: "...",
    intValue: 1,
    objectValue: "..."
  },
  key3: "..."
}

Hi, Having a custom string for pruned values seems useful (it might even be a well chosen single character, for a lighter JSON) but I don't understand what problems are solved by your two other changes. Note: it might be easier to discuss this in the Javascript room of Miaou: https://dystroy.org/miaou/8

Following our discussion on Miaou, I've made a new branch. See relevant documentation: https://github.com/Canop/JSON.prune/tree/custom-replacement#customization-replace-the--pruned--placeholder

Please review this branch and confirm it meets your needs.

That's exactly what I wanted ! It fits well to my needs. Thanks again.

OK, I'll merge ASAP.
