> `{"key":":a","value":"0x007f8f3c8baf88"}` seems clear enough to me.
Yes, but how can you distinguish between string value which is address or address to other ruby object:
`h = {a: "0x007f8f3c8baf88"}` to `h = {a: {b: 1}}`

Feature #11599: Dump entries of hash in ObjectSpace

Hi,
*This is my first c code contribution :)*
I am helping developing heap-analyzer (github.com/tenderlove/heap-analyzer), and currently the dumps lacks of "type metadata" information, like:
* Hash entries - the keys and value
* Array items - the items of the array
etc.
In the included patch, I have changed the dump of hash to add entries of hash.
For example, given the next hash:
~~~ruby
hash = {
int_key: 1,
str_key: "This is my string",
inner_hash: { b: 2 }
}
~~~
The dump result (ObjectSpace.dump(hash)) will be:
~~~json
{
"address": "0x007fbc01110340",
"type": "HASH",
"class": "0x007fbc0109b400",
"size": 3,
"entries": [
{
"is_key_address": false,
"key": ":int_key",
"is_value_address": false,
"value": "1"
},
{
"is_key_address": false,
"key": ":str_key",
"is_value_address": true,
"value": "0x007fbc01110390"
},
{
"is_key_address": false,
"key": ":inner_hash",
"is_value_address": true,
"value": "0x007fbc01110368"
}
],
"references": [
"0x007fbc01110390",
"0x007fbc01110368"
],
"memsize": 232,
"flags": {
"wb_protected": true
}
}
~~~
As you can see, I have the "entries" array, where each entry contains: "is_key_address", "is_value_address" - if the key/value are special consts the inspected value will be printed in the "key"/"value" properties, other their address will be print.
Hope you will accept the patch (and I can submit another one for arrays),
Yosi.
