Hi dears, today I've met a tool for Scilab that makes possible to handle JSON files into Scilab code. This tool is available through ATOMS or in http://forge.scilab.org/index.php/p/json/
Once installed, let's make a simple test with this tool just for validation.
First, it's created a json file (json_test.json) like below:
{
"orderID": 12345,
"softwareName": "Scilab",
"ToolName": "JSon",
"contents": [
{
"productID": 1,
"productName": "Test1",
"quantity": 1
},
{
"productID": 2,
"productName": "Test2",
"quantity": 3
}
],
"demoCompleted": true
}
Now, it's needed to get this file into Scilab, what we can do uding mgetl(.) function:
Take attention for the path of the file.
And the function JSONParse(.) returns the struct that corresponds to the data in the file, like this:
The expected result is
-->mystruct
mystruct =
orderID: 12345
softwareName: "Scilab"
ToolName: "JSon"
contents: [1x2 struct]
demoCompleted: "%T"
For accessing the fields, try this:
-->mystruct.orderID
ans =
12345.
-->mystruct.ToolName
ans =
JSon
-->mystruct.contents.productName
ans =
ans(1)
Test1
ans(2)
Test2
JSON is like XML pattern, much used for WebServices and in other Internet cases. Thus, I recommend to spend a few time taking a look about this technology and how Scilab can aggregate value to your solutions.
