FWIW it is so pleasant in Python that at work the .NET guys use Python
to do the same thing! :)

First off, thanks Carl and Danny for the code. The thing is, the system
call to python works for our needs and is easier than rolling my own. The
reason I started this thread in the first place is because it seems like
outputting human-readable json is common and often desired (see the upvotes

That's not really relevant in this case: there is no problem here
comparing the keys since they are all symbols.

Similar forking going on. :)
Here's another version (based on the json library in the standard
library, but hacked up a bit):

I think the point is: it should be very easy to do this; it's just a
matter of knowing what behavior you want.

Nick,
I've just built pretty-printing for JSON in a Gist you can see here:
https://gist.github.com/carl-eastlund/5398440
It's built on top of my own "stylish printing" library, mischief/stylish,
that you can install by running:
raco pkg install mischief
I'll add this to the mischief packag
I'm pretty sure what I want is the easy thing. We have data represented as
json, and we want changes to it to be easy to see in a difftool. Everything
on one line makes this hard. We just have a bunch of nested arrays and
dictionaries that need to be tabbed and newlined with no regard to width.

I've had good luck porting simple Python examples to Racket. Perhaps you
could start with the Python code that works as you expect, port it to
Racket, then refactor it to more Rackety ways:

That's exactly what I thought you were talking about. Doing it from
scratch seems wrong, and I thought that the right way to d
In talking with an experienced Racketeer, I realized that pretty-print has
a specific meaning in Racket that takes width into account. What I really
want is json with properly placed newlines and tabs (or spaces).
I'm willing to take a stab at it if it doesn't exist. I just wanted to make
sure I w

I think the `slideshow-latex' package should probably have an
"info.rkt" that contains
(define setup-collects '("slideshow/latex"))
so that only the "slideshow/latex" collection is set up. The package
manager otherwise infers that "slideshow" should be set up.

The make-file-or-directory-link function looks like it makes symbolic links. Is
