Or even just doing it for a single object?

I'm trying install aws sdk php v3. And I've got this:

composer require aws/aws-sdk-php
Using version ^3.133 for aws/aws-sdk-php

Installation failed, deleting ./composer.json.

The issue is that ubuntu only can get V2.3 by apt-get

how I could install the V2.5?

Doqnach

@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

@andrewcurioso

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)

Matthew Slowe

@jiscfoo

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.

Really I just need another major language (probably python) and it should be enough for a decent fork.

Although I'm not completely sold on the syntax for jmespath, it still is being used in major tooling (like aws-cli) and there is plenty of useful, small language additions that could be made without bloating it out of control.

Chris Armstrong

@chris-armstrong

See jmespath/jmespath.site#65 also

Chris Armstrong

@chris-armstrong

I've also forked the jmespath.test repository, upgraded its test infrastructure and schema, and added the compliance tests for GorillaStack's spec additions (split() function and to_json()/parse_json() proposals (both in our jmespath.js fork)
https://github.com/GorillaStack/jmespath.test
(see https://gorillastack-jmespath.netlify.com/proposals for descriptions of those proposals)

James Saryerwinnie

@jamesls

@chris-armstrong I'm the maintainer :(. I'd like to get the project back up and running again.

James Saryerwinnie

@jamesls

I also commented on jmespath/jmespath#65 as well, but I'm very interested in hearing everyone's ideas.

jdevillard

@jdevillard

@jamesls 👍

Chris Armstrong

@chris-armstrong

Thanks @jamesls . I'll make sure to at least get the test cases and proposal writeups for split() and to_json()/parse_json() submitted as PRs soon so they can go into the mainline at some point.

Somebody who can help me to find a way to have a default value if the value inside the JSON is not there?

This is my filter:
contains(roles[], 'admin') && 'Admin' || contains(roles[], 'editor') && 'Editor' || 'Viewer'

This is the error if element is missing:
t=2020-03-25T12:30:39+0000 lvl=eror msg="Failed to search user info JSON response with provided path" logger=oauth.generic_oauth attributePath="contains(roles[], 'Admin') && 'Admin' || contains(roles[], 'Editor') && 'Editor' || 'Viewer'" err="Invalid type for: <nil>, expected: []jmespath.jpType{\"array\", \"string\"}"
