I want a library that I can use both in clj and bb

babashka.curl also works in clojure

https://github.com/borkdude/babashka.curl

but so does clj-http-lite.

I'll try to use babashka.fcurl in clj then

😃

I'm trying to migrate ancient-clj to bb / clj

You can also use reader conditionals with :bb for babashka specific code

yup but It's not working on cider =(

what do you mean?

CIDER should support this, else it's a bug

Btw, I just tried from CIDER and it does seem to work?

=(

I was saying about the less opaque part of the #?()

that bb has to be lighter than clj

haha

but thanks 😃

Wow, forgot about -Spath , I want to added one more function to it to my use-case. e.g. greplace-all! in this case. And just want to learn how to leverage the pod system with it. I know it is very simple library (easy for me to start with). Thanks for creating Babashka and the pod system. It is really nice to be able to interact with many library via the cli.

:thumbsup:

qq: I am getting the error when I remove the following pr-str in the calling of the function. e.g. https://github.com/agilecreativity/pod-b12n-mgrep/blob/master/src/pod/b12n/mgrep.clj#L68

Must i return string all the time for the main function to work?

e.g. if I remove the pr-str from the last line I am getting some errors:

(defn grep
  [pattern file]
  (-> (mgrep/grep (re-pattern pattern) file)
      pr-str))

what is the error

Let me try to replicate it.

I'll be right back

Here is the errors:

#error {

I push my changes to develop branch: The diff was:

(defn grep
   [pattern file]
   (-> (mgrep/grep (re-pattern pattern) file)
-      pr-str))
+      #_pr-str
+      identity
+      ))

It is failing around this call:

(mgrep/grep "defproject" "project.clj")

The code to replicate the issue is in smoke-test.clj in the root of the project:

#!/usr/bin/env bb
(require '[babashka.pods :as pods])
(pods/load-pod ["pod-b12n-mgrep"])
(require '[pod.b12n.mgrep :as mgrep])

{:mgrep-project
 (mgrep/grep "defproject" "project.clj")

 :mgrep-deps
 (mgrep/grep "mvn" "deps.edn")

When run directly I am getting the correct result:

(grep "defproject" "project.clj")

;;=>
({:file "project.clj", :line "(defproject net.b12n/pod-mgrep \"1.0.0\"", :line-number 1, :regex #"defproject", :re-seq ("defproject")})

your error seems to indicate you're trying to send a regex over the wire?

user=> (edn/read-string (pr-str #"foo"))
Execution error at user/eval5 (REPL:1).
No dispatch macro for: "

I see, I noticed that also that anything that is not string will not work. Right?

The protocol uses EDN or JSON. So arguments serialized as EDN should be also readable as EDN

Got it, so I can also send it using json by specify “format” “json” ?

yes.

You can also define "client side" functions to work around limitations.

Can you explain what is client side function?

E.g. you can define (defn foo [x] (if (regex? x) {:regex (str x)}) and then decode :regex as a regex in your pod.

see https://github.com/babashka/babashka.pods#client-side-code

Thank you. Now it all make sense to me.

I'm also using this in the sql pods to send connections between bb and the pod. connections are just represented as a map with an id in it

and I translate those maps back to a connection on the pod side

one other tip if you weren't aware of it: you can test your pod with the pod library on the JVM before natively compiling it

this makes iterating on it faster

I see, so just add that as dependency and try to see if that work first.

yes

I should do that going forward. Thanks for the tips

In the case of regex above, I guess I can also use reader to handle it

{"readers" {"my/tag" "clojure.core/identity"}}

I totally forgot about that, but I guess so 🙂
