For my archive: the [WayBack] How do I pretty-print JSON in Delphi? – Stack Overflow answer by [WayBack] Bob:
If you do not want to use any external library, and you’re using a Delphi XE5 or newer, there is a very handy
TJson.Format()function in theREST.Jsonunit.uses json, REST.Json; { ... } function FormatJSON(json: String): String; var tmpJson: TJsonObject; begin tmpJson := TJSONObject.ParseJSONValue(json); Result := TJson.Format(tmpJson); FreeAndNil(tmpJson); end;

Two interesting sites to ease transforming JSON fragments in log-messages to a table system, for instance Excel.
Custom format ##0.00E+00 that just shows the exponents in multiples of 3 (so kilo, mega, giga, etc)[WayBack] formatting – How can I format bytes a cell in Excel as KB, MB, GB etc? – Stack OverflowThis way I copied the example code into adjecent Excel areas, so I could compare the values and calculate memory increase of a Delphi application.

For my link archive:
Back-ticks can be very useful for instance when you need to specifying json tags.

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 “
JSONsorted” file format that usesjqto pretty print and sortJSONdata 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.
XMLalignment algorithms were being actively researched back in the aughts and they should trivially transfer toJSON.
…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:

[WayBack] http://search.cpan.org/dist/XML-SemanticDiff/xmldiff(Python)
[WayBack] https://www.logilab.org/project/xmldiff
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.

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" www.google.comsource: 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]

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.

Every time I need to use JavaScript there’s this tiny voice in the back of my head “Please don’t”, for instance because of
JavaScript has two sets of equality operators:
===and!==, and their evil twins==and!=.
This time it did it again: I used JavaScript. My need was to verify a basic URI in JavaScript, so I wrote this function based on RFC 3986 [WayBack] which in Appendix B has a nice regular expression: ^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?
function isValidUri(uri){
var uriRegExPattern = "^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?";
var uriRegEx = new RegExp(uriRegExPattern);
return (uriRegEx.test(uri));
}
It would crash. But JavaScript is JavaScript, so even a site like JSFiddle wouldn’t show an error (later I found out that enabling the console on http://jsbin.com/wamavacuco/edit?html,console,output does show the error in the console complete with stack trace).
