Subject: luci-lib-jsonc: allow encoding empty lists
|
||
|
|
|
||
|
|
To be consistent with the behavior of luci-lib-json, an empty Lua table
|
||
|
|
should be encoded to an empty JSON list, not an empty JSON object.
|
||
|
|
|
||
|
|
To still allow encoding empty JSON objects, the usage of anything other
|
||
|
|
than a number or a string as a key (for example an empty table or a
|
||
|
|
function) can be used to force encoding as an object:
|
||
|
|
|
||
|
|
json.stringify({}) -- "[]"
|
||
|
|
json.stringify({[{}] = true}) -- "{}"
|
||
