Add clojure.pprint about babashka HOT 14 CLOSED

@saikyun You can print output on multiple lines using -o:

ls -la | bb -io '(map #(apply str (drop 10 %)) *in*)'

from babashka.

I'm in favor of this idea, but I might go for fipp or some other pretty printer, since that works well with GraalVM. I haven't been able to use clojure.pprint (unchanged) with GraalVM.

from babashka.

Ah, all right. I came up with some more context:
One issue I have atm is that if I have a collection of lines (e.g. (= *in* '("a", "b", "c")), I can't really come up with a good way to print them nicely. If I just return them it can get unwieldy, and I can't use doseq nor doall, so I don't know how to run println multiple times either.

from babashka.

Here's an example: ls -la | bb -i '(map #(apply str (drop 10 %)) *in*)'
If we imagine that ls -la is log information or similar, where each line is too wide for the screen, I'd want to cut off the first 10 letters, then print all the lines as ls -la would. :)

It'd also be pretty cool if a pretty printer (whichever you decide upon) could be used as default for all output data. Maybe it's too performance heavy though, so maybe it could be a flag or such.

from babashka.

Awesome, thanks! This actually solves a lot of problems. :D

Just some feedback, I didn't quite understand this -o: write lines to stdout. Not sure what it could say instead, maybe -o: on multiple elements, prints each element on a new line or similar... :)

@saikyun Thanks for the feedback, I'll think about a better way to describe that option. It also works for a single string btw.

@saikyun Thanks for using babashka btw. Maybe you have some thoughts about this issue? #48

Since you can already pprint with jet I'm closing this for now.

@borkdude I'm happy to try it out. :) I enjoy being able to use clojure in more places.
Ah, didn't know about jet, that's great to know.
It seems like you've already made some decisions wrt #48. I don't know much about spawning processes, so I'd have to play around with it.

from babashka.

FWIW one downside to this resolution is that e.g. taoensso.timbre doesn't work (transitive dependency on https://github.com/AvisoNovate/pretty/blob/master/src/io/aviso/exception.clj which in turn specifically wants clojure.pprint).

from babashka.

@lvh I'm not sure what you are referring to, but the latest babashka is now based on clojure.pprint proper. See issue #571. What problem are you seeing with 0.2.3?

from babashka.

@lvh Oh I see. That namespace uses pp/simple-dispatch which is currently not exposed in bb. Let's make a different issue for that and fix it.

from babashka.

Can confrim fipp works great with babashka. https://github.com/brandonbloom/fipp
