how to use new json parser to create an array?

I am trying to parse json with weather data and I would like to copy a json array into a tasker array because the path to the variables I want is long and I'd rather use a shortened name for readability

If I go to https://forecast.weather.gov/MapClick.php?lat=37.498&lon=-122.267&FcstType=json then the output has in part:

"time":{ "layoutKey":"k-p12h-n14-1", "startPeriodName":[ "Tonight", "Friday", "Friday Night", "Saturday", "Saturday Night", "Sunday", "Sunday Night", "Monday", "Monday Night", "Tuesday", "Tuesday Night", "Wednesday", "Wednesday Night", "Thursday"

I would like to store this into an array but I don't know how to do so. I tried to use

Array Set %array_days, http_data.time.startPeriodName(1) http_data.time.startPeriodName(2)

but %array_days just gets the words as if they were text instead of recognizing them as json data that should be automatically parsed

Variable Set appears to perform the parsing since if I use

Variable Set %some_day, http_data.time.startPeriodName(1)

then %some_day is "Tonight"

why doesn't Array Set parse the json?
is there a way to copy the startPeriodName json array into a tasker array?

Hi! :)

You can do it like this for example:

Task: Test

Variables: [ %test:has value ]

A1: HTTP Request [
Method: GET
URL: https://forecast.weather.gov/MapClick.php?lat=37.498&lon=-122.267&FcstType=json
Timeout (Seconds): 30
Structure Output (JSON, etc): On ]

A2: Array Set [
Variable Array: %array_days
Values: %http_data.time.startPeriodName()
Splitter: , ]

A3: List Dialog [
Mode: Select Single Item
Title: Days
Items: %array_days
Close After (Seconds): 30
First Visible Index: 0 ]

Hope this helps!

Hey thanks for the answer. It helped a lot. Could you give me an idea on how to read several values from JSON into one array?

For example:

[
    {
        "station": "Supermarkt-Tankstelle Dettingen",
        "status": "open",
        "e5": 1.729,
        "differenceE5": -0.03,
        "e10": 1.669,
        "differenceE10": -0.03,
        "diesel": 1.509,
        "differenceDiesel": -0.03,
        "discount": "0"
    },
    {
        "station": "Shell Neuhausen",
        "status": "open",
        "e5": 1.789,
        "differenceE5": -0.03,
        "e10": 1.739,
        "differenceE10": -0.03,
        "diesel": 1.559,
        "differenceDiesel": 0.04,
        "discount": "0"
    },
    {
        "station": "OMV Metzingen",
        "status": "open",
        "e5": 1.779,
        "differenceE5": 0.04,
        "e10": 1.719,
        "differenceE10": 0.04,
        "diesel": 1.569,
        "differenceDiesel": 0.04,
        "discount": "0"
    },
    {
        "station": "Shell Metzingen",
        "status": "open",
        "e5": 1.789,
        "differenceE5": -0.04,
        "e10": 1.739,
        "differenceE10": -0.04,
        "diesel": 1.559,
        "differenceDiesel": 0.04,
        "discount": "0"
    },
    {
        "station": "Miller Metzingen",
        "status": "open",
        "e5": 1.719,
        "differenceE5": -0.04,
        "e10": 1.659,
        "differenceE10": -0.04,
        "diesel": 1.499,
        "differenceDiesel": -0.01,
        "discount": "0"
    },
    {
        "station": "Total Metzingen",
        "status": "open",
        "e5": 1.709,
        "differenceE5": -0.05,
        "e10": 1.669,
        "differenceE10": -0.05,
        "diesel": 1.519,
        "differenceDiesel": -0.05,
        "discount": "0"
    },
    {
        "station": "avanti Metzingen",
        "status": "open",
        "e5": 1.699,
        "differenceE5": -0.01,
        "e10": 1.639,
        "differenceE10": -0.01,
        "diesel": 1.499,
        "differenceDiesel": -0.03,
        "discount": "0"
    }
]

And I would like to have an array with the station + e10 concatenated like:

Supermarkt-Tankstelle Dettingen 1.669, Shell Neuhausen 1.739

Is this possible with one array set command or do I need two array, fill them independently like:

Array Set [ Variable Array: %tabelle Values: %arcomm.station() Splitter: , ]

thanks

Martin

Ah - found it myself:

Arrays Merge does the trick

Task: List Test
    
    A1: Arrays Merge [
         Names: %arcomm.e10
         %arcomm.station
         Merge Type: Simple
         Joiner:  
         Output: %tabelle ]
    
    A2: List Dialog [
         Mode: Select Single Item
         Title: Test
         Items: %tabelle
         Button 1: ok
         Button 2: cancel

         Close After (Seconds): 30
         First Visible Index: 0 ]
