Json_select without a key

Development Web Sources Discussion

I had to run a few tests to be sure, but the ability to read unnamed root arrays seems to be limited to json_foreach.

Given a sample named JSON array of literals and a few test commands:

Use "{"array":["a","b","c","d"]}"
json "ON" "current"
json_select_array "array" -1 ","
json_select_array "array" 1
json_foreach "array"
json_foreach_end

I get (respectively):

a,b,c,d     ##_ json_select_array "array" -1 ","
a           ##_  json_select_array "array" 1
4           ##_ json_foreach "array"   ---> (number of literals in array)

The same (array name removed) commands on the unnamed variant:

Use "["a","b","c","d"]"
json "ON" "current"
json_select_array "" -1 ","
json_select_array "" 1
json_foreach ""
json_foreach_end

now returns

<empty>     ##_ json_select_array "" -1 ","
<empty>     ##_ json_select_array "" 1
4           ##_ json_foreach ""   ---> (also number of literals in array)

So it would seem that

only json_foreach "" has support for unnamed root arrays, unlike json_select_array.

@Florian can I bother you again to chime in an opinion on this, please? :sweat_smile:
