Hello everyone
I'm asking here because this is more related to web programming than
Tcl programming at large.
I was using Tcllib's json utility to compose return messages to be
sent in response to Ajax requests generated with JQuery. I assumed
that creating such Json messages was rocket science and ended up
wasting time debugging an error that arose simply because of missing
quotes
package require json
::json::dict2json [dict create a1 v1 a2 v2 a3 v3 a4 "v v v v4"]
{"a1": v1
,"a2": v2
,"a3": v3
,"a4": v v v v4
}
Ok, having a simple procedure that creates json correctly recognized
and parsed messages took a handful of seconds, still I grew uneasy
after I got to know that the Tcl standard Json utility is apparently
useless for a relatively common task such as sending data in response
to an Ajax interaction.
Am I missing something? Is it possible that no one ever complained
about it?

Dear Massimo,
I think that this command exists, but is undocumented:
https://core.tcl-lang.org/tcllib/doc/trunk/embedded/md/tcllib/files/modules/json/json.md
So, not supposed to be used.
Regarding json, I am using the rl_json library. Not a great API, but
works and is somewhat fast.
Best,
George
