core.base.json
Xmake provides a built-in json module, based on the implementation of lua_cjson, we can use it to quickly and directly interoperate between json and lua table.
We can use import("core.base.json")
for direct import and use.
There are also some examples here: Json Examples
json.decode
- Get the lua table directly from the string decoding json
lua
import("core.base.json")
local luatable = json.decode('[1,"2", {"a":1, "b":true}]')
print(luatable)
{
1.0,
"2",
{
b = true,
a = 1.0
}
}
NOTE
If there is null in it, you can use json.null
to judge
json.encode
- Encode a lua table
lua
local jsonstr = json.encode({1, "2", {a = 1}})
It should be noted that if you need to encode null, you need to use json.null
, for example
lua
local jsonstr = json.encode({json.null, 1, "2", false, true})
json.loadfile
- Load the json file directly and parse it into a lua table
lua
local luatable = json.loadfile("/tmp/xxx.json")
json.savefile
- Save the lua table to the specified json file
lua
json.savefile("/tmp/xxx.json", {1, {a = 1}})
