Of course you can also just use comment forms

Thanks! 🙂

You should do it the other way around:

(binding [*out* sci/out] ...)

doh! That was silly. It also needs to be inside of the :namespaces functions I think?

?

Like this

(-> (sci/init
         {:namespaces {'my {'print (fn []
                                     (binding [*out* @sci/out]
                                      (println "TESTING")))}}})
        (babashka.nrepl.server/start-server! {:host "127.0.0.1" :port 23456}))

Instead of outside the sci/init like I had list time

I think that would make it more robust yes

Thanks, it works! 😄

oh cool! Thanks Borkdude!

I improved the example now, click link again

Love it, can I steal this (or something like it) for How to do things with babashka?

once again improved, please check again. I emphasized streaming https://github.com/babashka/process#processing-streaming-output

@U06F82LES of course!

Is there a way to avoid having to add nil at the end to skip the gobbldygook at the end?

not really, but maybe we could make this an env var or so

it was kind of a mistake to print the last expression when executing a file, but when I did a poll most people wanted to keep it ;)

huh interesting - I think it's a little flaw (but doesn't matter in the end)

@U06F82LES reading an entire file into memory is done easier like this:

(:out (shell {:out :string} "cat /etc/hosts"))

I mean, the output from a process -> string

👍 updated the 2nd example

Tangentially I like to split the command and args, because otherwise I get anxious - who does the string splitting again? does it know about single quotes? what if I need to interpolate a variable here? I feel like separate args are simpler in the Hickeyan sense

you can provide separated args yourself too

(shell "cat" "/etc/hosts")

yeah I know! I did in the snippet

it's all good 🙂

The nil at the end of a bb program: the "QED" of a bb script ;)

@U06F82LES I thought about changing the printing of the output like 2 years or so ago, but then the Rich Hickey on my shoulder told me that it could be a breaking change...

You can use

how do you use the repl when writing code like this? Mine just freezes

or do you use i.e. -x to run the functions?

it depends, I sometimes also write little scripts and just execute them

especially when dealing with infinite output stuff like this ;)

> Note that the amount of parens is exactly the same though 🙂. I hope that James Gosling reads that .

(for those of you who were not at reClojure, James Gosling was a keynote speaker and he hinted at his struggles with parens)

I think he was talking about writing lisp without much editor help when doing his PhD in the eighties 🙂

Nice article! Fun to learn more about how bb works
