R: Use YAJL to read json key values longer than 50 char in RPGLE

Hi Scott.
That would solve my problem.
Thank you very much.

Oggetto: Re: Use YAJL to read json key values longer than 50 char in RPGLE

Hi Marco,

I can't change the existing yajl_object_elem() because this would break
compatibility. All existing YAJL users would have to change their code
and recompile. I'd rather not make changes like that.

I could add a new subprocedure that returns a longer key, however.

Hi.
I'm using Scott Klement YAJL library to read from a rpgle program a json file with long key values (the key values are paths of devices).
Here an example:

{
"return": [
{
"x000002.001": {
"/var/lib/docker/containers/cc1b32cb7175dec13c0beac61ace0b3e82018aba025c6a43316d0229d5603c39/mounts/shm": "0%",

},
"x000001.001": {
"/home": "5%",
"/dev": "0%",
"/boot": "8%",
"/sys/fs/cgroup": "0%",

},

"/boot": "8%",
"/var/lib/docker/overlay2/b9fd3d45f0e49d0d80f156c3bfe6113bc0391dcd8233974457bf8ddab156a68a/merged": "6%",

"/dev/shm": "1%"
},
"x000001.003": false
}
]
}

The procedure YAJL_OBJECT_ELEM return a key of 50 char varying retrieving the value from a pointer.

D YAJL_OBJECT_ELEM...
D PR like(yajl_val)
D node like(yajl_val) value
D idx 10i 0 value
D key 50a varying

So i tried to define key as 500 char varying in all the procedures and recompile the entire library.

D YAJL_OBJECT_ELEM...
D PR like(yajl_val)
D node like(yajl_val) value
D idx 10i 0 value
D key 500a varying

That worked fine for me so I would like to ask Mr Klement for a change in future versions of YAJL library.
Thanks!

Marco
