Hi Alex,
the JSONtoArray() function is part of the mergJSON external.
The README of this external describes how to use this function
and it's counterpart JSONtoArray as follows:
Thanks Ralf. I did see that code in the dictionary - but it also says
that those functions are provided in
thews.goulding.script-library.mergjson library, so (I think) I shouldn't
need to put them in myself.
In fact, I did try it anyway - but that simply changes the error to
"handler not found: mergJSONDecode"
Another option would be to load the JSON extension and to use
the JsonImport() function.
Didn't know about jsonImport; it's not mentioned in the dictionary, but
I now see it shows up in a few lessons, etc.
However,I think the real problem for me is "... to load the JSON
extension ...". I wasn't aware I had to load those extensions which are
already part of the standard package (maybe I did that years ago and
have had time to forget :-).
I can't find anything about loading extensions other than what to do in
the IDE.
How do you load extensions to LC Server ? On a shared web provider ?
(on-rev)
Thanks,
Alex

But if you don't need interoperability, you wouldn't need to write a
parser, since LC includes a good one built into the engine.
What did I miss?
The fact that Livecode's support for JSON is, hmmm, mediocre at best ??
The parser "built-in" seems to work fine in the IDE, but not on the
server :
<?lc
set the errormode to inline
put the version
put "{'name':'asdf'}" into t
replace "'" with quote in t
put JSONtoarray(t) into tA
put the keys of tA
fails with -
file "/home/alextwee/public_html/rampuk/tJSON.lc"
row 7, col 5: Function: error in function handler (JSONtoarray)
row 7, col 5: put: error in expression
(there's no mention of any platform restricitons in the dictionary).
I tried copying in the sample ode for wrapping JSONToArray around
mergJSONDecode,
which then fails with "error in function handler mergJSONDecode.
(I must admit I encountered this a while ago, figured it was probably
a temporary issue
so I replaced JSON by LSON, and forgot all about it.) This discussion
prompted me to re-try it.
I can't believe this problem isn't causing widespread problems, so
it's probably
something specific about me, or my on-rev account. If anyone has
suggestions, I'll
try them; if not, I'll put it as a bug report into QCC see what happens.
Alex.
