- Usage:
-
- -- Lua script:
- local t = {
- ["name1"] = "value1",
- ["name2"] = {1, false, true, 23.54, "a \021 string"},
- name3 = json.null()
- }
-
- local json = json.encode (t)
- print (json)
- --> {"name1":"value1","name3":null,"name2":[1,false,true,23.54,"a \u0015 string"]}
-
- local t = json.decode(json)
- print(t.name2[4])
- --> 23.54
-
- Notes:
- 1) Encodable Lua types: string, number, boolean, table, nil
- 2) Use Json.Null() to insert a null value into a Json object
- 3) All control chars are encoded to \uXXXX format eg "\021" encodes to "\u0015"
- 4) All Json \uXXXX chars are decoded to chars (0-255 byte range only)
- 5) Json single line // and /* */ block comments are discarded during decoding
- 6) Numerically indexed Lua arrays are encoded to Json Lists eg [1,2,3]
- 7) Lua dictionary tables are converted to Json objects eg {"one":1,"two":2}
- 8) Json nulls are decoded to Lua nil and treated by Lua in the normal way
