jsoniopipe - exaples?

[Zz]

Hi,

Here are some samples from the std.json documentation.
Any idea on how to do something similar using jsoniopipe?

Directly copied from https://dlang.org/phobos/std_json.html

import std.conv : to;

// parse a file or string of json into a usable structure
string s = `{ "language": "D", "rating": 3.5, "code": "42" }`;
JSONValue j = parseJSON(s);
// j and j["language"] return JSONValue,
// j["language"].str returns a string
writeln(j["language"].str); // "D"
writeln(j["rating"].floating); // 3.5

// check a type
long x;
if (const(JSONValue)* code = "code" in j)
{
     if (code.type() == JSONType.integer)
         x = code.integer;
     else
         x = to!int(code.str);
}

// create a json struct
JSONValue jj = [ "language": "D" ];
// rating doesnt exist yet, so use .object to assign
jj.object["rating"] = JSONValue(3.5);
// create an array to assign to list
jj.object["list"] = JSONValue( ["a", "b", "c"] );
// list already exists, so .object optional
jj["list"].array ~= JSONValue("D");

string jjStr = 
`{"language":"D","list":["a","b","c","D"],"rating":3.5}`;
writeln(jj.toString); // jjStr
