… compare two JSON structures and pin-point … the differences – – Nicholas Ring – Google+

Posted by jpluimers on 2019/08/20

I’ve added a few WayBack/Archive.is links to the interesting comments by Zoë Peterson from Scooter Software (of Beyond Compare fame) at [WayBack] … compare two JSON structures and pin-point … the differences – – Nicholas Ring – Google+:

Beyond Compare 4 has an optional “JSON sorted” file format that uses jq to pretty print and sort JSON data before comparing it. It’s not included out of the box yet, but you can get a copy here:

If you’re interested in an actual algorithm and not just an app, I don’t have a suggestion handy, but could dig one up. Tree alignment is more complicated than sequence alignment and we did do research into it, but it was quite a few years ago and didn’t get incorporated into BC. XML alignment algorithms were being actively researched back in the aughts and they should trivially transfer to JSON.

It looks like our research mostly ended around 2002, and I wasn’t personally involved in it, so I don’t know how helpful this will be, but here’s what I have:

The general idea in the thread is that JSON – though not as formalised as XML – does have structure, so if you can normalise it, then XML ways of differencing should work.

Normalisation also means that you need to normalise any floating point, date time, escaping, quoting, etc. Maybe not for the faint of heart.

Stuff on my research list thanks to Martijn Laarman (@Mpdreamz)

Posted by jpluimers on 2018/02/08

Quite some time ago, I attended a great introductory elasticsearch/kibana workshop by Martijn Laarman (@Mpdreamz, github.com/Mpdreamz and SO martijn-laarman) that lead me into researching a lot of interesting new things:

Sending various HTTP request kinds using curl

Posted by jpluimers on 2017/07/25

I’ve been using cURL but always had a feeling not to its potential basically because the cURL man page [WayBack] is both massive and lacks concrete useful practical examples.

For instance, I knew about the --header and --verbose options (I always use verbose names even though shorter -H and -v exist) to pass a specific header and get verbose output, but the man page basic examples like this by Tader:

curl --header --verbose "X-MyHeader: 123" http://www.google.com

source: How to send a header using a HTTP request through a curl call? – Stack Overflow [WayBack]

There are some more examples at bropages.org/curl but they’re hardly organised or documented.

So I was really glad I found the below answer [WayBack] by Amith Koujalgi to web services – HTTP POST and GET using cURL in Linux – Stack Overflow.

But first note that recent versions (around 7.22 or higher) of cURL now need to combine the --silent and --show-error (or in short -sS) parameters to suppress progress but show errors: linux – How do I get cURL to not show the progress bar? – Stack Overflow [WayBack]

Back to the examples

Bash that JSON (with jq) — Librato Blog

Posted by jpluimers on 2017/04/18

 Glueing together APIs requires working with JSON: parsing it, extracting it, transforming it. JQ is a fast, lightweight, flexible, CLI JSON processor, that does the job well. Learn how to use it by getting your hands dirty with a JSON blob that represents the open issues in the public Docker GitHub repository.
