    anyone can help me with the function max() ?

    @Harbie34

    Hi, there!
    I'm trying to convert the result of AWS CloudWatch Logs Insights, but I can't.

    Like this:

    {
    "results": [
        [
            {
                "field": "@timestamp",
                "value": "2020-02-03 15:03:26.315"
            },
            {
                "field": "@message",
                "value": "some messages 1"
            },
            {
                "field": "@ptr",
                "value": "xxx"
            }
        ],
        [
            {
                "field": "@timestamp",
                "value": "2020-02-03 15:03:27.495"
            },
            {
                "field": "@message",
                "value": "some messages 2"
            },
            {
                "field": "@ptr",
                "value": "xxx"
            }
        ]
    ],
    "statistics": {
        "recordsMatched": 887.0,
        "recordsScanned": 887.0,
        "bytesScanned": 101532.0
    },
    "status": "Complete"
}

    To this:

    [
    [ "2020-02-03 15:03:26.315", "some messages 1" ],
    [ "2020-02-03 15:03:27.495", "some messages 2" ]
]

    Can anyone help me?

    JMESPath makes this trickier than it needs to be, but here it is @Harbie34:
    map(&[([?field=='@timestamp'])[0].value, ([?field=='@message'])[0].value ], results)
    Harbie34
    @Harbie34
    @chris-armstrong Wow! Excellent! I'll study the map function more. Thanks!
    Chris Armstrong
    @chris-armstrong
    No worries - I think this one can also be done with filter expressions and pipes but I haven't explored that.
    Harbie34
    @Harbie34
    @chris-armstrong Hmm... I'll try to think a little more, too.

    I feel really dumb, but can't seem to figure out how to transform this:

    {
    "Foo": "somekey",
    "Bar": "somevalue"
}

    into:

    { "somekey": "somevalue" }

    the closest I can get is like:

    { Foo : Bar }

    but that yields:

    {
  "Foo": "somevalue"
}

    so it's the key in the hash part I cant figure out how to get
    (I want to make the new hash's key, the value of an existing key in the input hash)

    Jens J.
    @zerog2k

    so I have read somewhere this may not be possible w/ stock JMESPath

    Jmespath does not allow to use dynamic names in multi select hashes.

    but there is some extension:
    https://github.com/grofers/go-codon/wiki/Jmespath-extensions#5-support-for--expressions-as-key-when-performing-multi-select-hash
    (wanted to be able to do this in aws cli --query )

    Jens J.
    @zerog2k
    i guess i need to pass output through jq from_entries
    aws ec2 describe-tags --filters "Name=resource-id,Values=${INSTANCE_ID}" --query 'Tags' | jq from_entries >/tmp/tags.json
    basically gives me what I want ;)

    Is there a way to turn an object of objects into a list of {key1, key2, value} objects?
    For example: {animal: {ant: 1, bee: 2, cat: 3}, vegetable: {apple: 4, banana: 5}, mineral: {axe: 6, bell; 7}} into [{key1: "animal", key2: "ant", value: }, {key1: "animal", key2: "bee", value: 2}, ... {key1: "mineral", key2: "bell", value: 7}]
    wu-lee
    @wu-lee
    Or even just doing it for a single object?

    The issue is that ubuntu only can get V2.3 by apt-get
    how I could install the V2.5?

    @Doqnach
    how do you mean apt-get?
    this says composer @dr7tbien
    try composer why --tree mtdowling/jmespath to see why it is locked to 2.4.0

    Hello all... is there a way to emulate a ternary operator? Basically I want one value is there is a match and another value if there isn't
    Never mind, this works
    locations[0].state == 'NY' && 'a' || 'b'

    Wow, just saw the link to https://github.com/grofers/go-codon/wiki/Jmespath-extensions#5-support-for--expressions-as-key-when-performing-multi-select-hash. These are great!

    Hi Everyone, new to jmespath and yaml. So I've a requirement where I'm substituting region as a variable, I'm getting this error. jmespath.exceptions.LexerError: Bad jmespath expression: Unknown token '-':
    "123456789012".us-east-1 . Any help would be appreciable.
    this is my original yaml file expression expr: '"{account_id}".{region}'
    James Saryerwinnie
    @jamesls
    You need to quote values that have chars that aren't a-zA-Z0-9
    try "{account_id}"."{region}"
    lakshmi Pendyala
    @lpendyala_gitlab
    expected <block end>, but found '<scalar>'
    in "<unicode string>", line 18, column 31:
    expr: "{account_id}"."{region}"
    James Saryerwinnie
    @jamesls
    I don't think that's a jmespath error? Here's a full example:
    $ echo '{"12345": {"us-east-1": "value-i-want"}}' | jp.py '"12345"."us-east-1"'
"value-i-want"
    lakshmi Pendyala
    @lpendyala_gitlab
    this expression is in yaml file
    even for me it's working good when I queried this command cat /tmp/test.json | jp '"987654321012"."us-east-1"'
    James Saryerwinnie
    @jamesls
    oh, maybe just quote the whole value in the yaml file. I'm guessing yaml's thinking it's two separate strings. So:
    expr: '"{account_id}"."{region}"'
    lakshmi Pendyala
    @lpendyala_gitlab
    It's not throwing any error and at the same time it's not getting evaluated at all

    Hi people, I am super new in jmespath. I had just a look to the docs for pyhon and I did not have chance to play with it yet. Just a very high level question. Is there any way to make search to work in the opposite way? I mean, instead to search a key:value, to exclude the key:value passed and return all the rest
    Thank you very much!
    James Saryerwinnie
    @jamesls
    No, not right now :(. I know people want that feature though.
    Federico Olivieri
    @Federico87_gitlab
    If I have something like this : {"peers": {"ns1.sys.cloudsys.tmcs": {"delay": [ 0.476, 0.371 ]}, "insert": { "10.75.33.5": { "delay": [ 0.384 ]}}, "delete": {"ns2.sys.cloudsys.tmcs": { "delay": [ 0.465 ]}}}
    and i want take just insert and delete, is it possible to do with wildcards? kind of peer.[insert|delete] ?
    James Saryerwinnie
    @jamesls
    Something like this? http://play.jmespath.org/?u=3beadfb8-aeb4-430c-b7d7-6a8c4ed3f27b
    Federico Olivieri
    @Federico87_gitlab
    Yeap! Amazing! Thanks a lot. I will go tomorrow through all docs. Great application btw!

    Hi people, just learning jmespath. Based on my first experiments I can use jmespath as a template language (meaning using the desired json as a template and using the path expressions to get the necessary values). Using it as such would it be possible to create an object depending on a condition? So if the condition is true create object A else object B or nothing?
    James Saryerwinnie
    @jamesls
    Not really, but conditionals like that is something I'm looking to add.

    Question. I have a json like the belo and I want to catch just interfaceStatus I can do interfaces.*.interfaceStatus and I get the right result, however I lose Ethernet47 so I am not sure to which interface the interfaceStatus belongs to
    "Ethernet48": {
            "lastStatusChangeTimestamp": [
                1580496491.6286151,
                1580496491.6286182
            ]
        },
        "Ethernet47": {
            "lastStatusChangeTimestamp": [
                1580496491.629291,
                1582706128.6775026
            ],
            "interfaceStatus": [
                "connected",
                "disabled"
            ]
        }
    I can workaround with some code but I was wondering if there is some sort of reference/dereference that I can apply to .*. and get back the value of * where jmspath match
    Chris Armstrong
    @chris-armstrong
    JMESPath doesn't have a way to do this I'm afraid - there are no backreferences to a previous match, nor can you convert the object to a set entries (like JavaScript Object.entries()) and map over the result.
    Chris Armstrong
    @chris-armstrong
    Adding an entries function is a good target for a specification addition, but there is no formal process for those at the moment (development on the main repo seems to be stalled)

    Afternoon. I am wondering if there are jmespath packages for Alpine Linux…?
    James Saryerwinnie
    @jamesls
    @chris-armstrong I'm thinking it might be helpful to create a new repo that's just for proposing new functionality. Right now there's not really a good way to do that.
    Chris Armstrong
    @chris-armstrong

    There is an official repo (the web site / test suite ones), but I'm not the maintainer (who hasn't responded to some issues for several years), so I don't know who should take responsibility.

    FWIW, I've forked the official documentation site (so I can host it with TLS) and the JS implementation for GorillaStack, and I'm maintaining my own specification additions in the doc site and the JS implementation.

    See:
    https://github.com/gorillastack/jmespath.js
    https://github.com/gorillastack/jmespath.site

    I should probably fork the test suite and get my additions added to it so that others can add my changes if no-one else is going to maintain the site and test suite.
