Subject: luci-lib-jsonc: allow encoding empty lists
X-Git-Url: http://git.archive.openwrt.org/?p=project%2Fluci.git;a=commitdiff_plain;h=e7645d557c1bd532e49c69f0ab781cf6342067d1;hp=e7645d557c1bd532e49c69f0ab781cf6342067d1

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})       -- "{}"
