Good work @pesterhazy I think it would be nice to enable syntax highlight by adding clojure to the code fence

Right, forgot it again - done

@arturdumchev would reading this have answered the question you had?

@pesterhazy Were you going to announce this somewhere? I'd want to share it on social media, but if you'd rather wait, then I'll wait as well

Ok, managed to find my AWS credentials and uploaded the post to my blog https://presumably.de/how-to-do-things-with-babashka.html

I think it would be great to share it on social media! I think there's enough stuff there to be useful now

@pesterhazy I shared it on twitter and this will also go to my mastodon: https://twitter.com/borkdude/status/1605591648875864064

Also shared to #C8NUSGWG6

@pesterhazy There's a small error here:

["cat" "/etc/hosts"]

And the destroy-tree isn't necessary here

Do you mean this line? It doesn't work without the [] (it's using process, not shell) https://github.com/pesterhazy/presumably/blob/master/posts/howto-babashka.md?plain=1#L102

To be clear, this doesn't work for me

(require '[babashka.process :refer [process]]
         '[ :as io])

(let [stream (process {:err :inherit} "cat" "/etc/hosts")]
  (with-open [rdr (io/reader (:out stream))]
    (doseq [line (line-seq rdr)]
      (println (str "#" line))))
  nil)

----- Error --------------------------------------------------------------------
Type:     java.lang.ClassCastException
Message:  java.lang.Character cannot be cast to java.util.Map$Entry
Location: /Users/user/arena/bin/scrapbb:6:14

This is because you're using a too old bb ;)

The first map is just ignored probably even in this case

What's bb --version?

% bb --version
babashka v1.0.165

This doesn't have the updated process API

From the process docs (with the newly updated API):

Hm, I updated to 1.0.168 Now "cat" "/etc/hosts" works. But ["cat" "/etc/hosts"] doesn't work anymore - is this a breaking change?

I'm pretty sure I got this way of using it from the docs (at the time)

No, this is not a breaking change, (process {} ["foo"]) was never supposed to work, the first map should have been a process that you piped into the next process. The documented API was: (process ["foo"] {?opts})

and this still works btw

You can check the docs of the previous version if you don't believe me ;) https://github.com/babashka/process/tree/ff4085c4dc571966a2bfa239b778de5e08b76aaf

I believe you! What I didn't get was that I misplaced the options map

Makes sense

OK, I fixed all usage of babashka.process/process and babashka.process/sh to use the new style (`opts? arg1 arg2 ....`) https://presumably.de/how-to-do-things-with-babashka.html?cb=1#read-command-output-line-by-line

Also added this note > Note: this example requires babashka v1.0.168 or higher.

Cool, thanks!

The new style of calling the fns in babashka.process is much nicer

I posted a link to HN with the title "How to Babashka (Clojure vs. Bash)" (I think mentioning bash and Clojure in the title will get more views and "things" is a word which could be left out imo)

LSP does give me jump-to-definition for vars in my own namespace, so it's working that far

Not jump to definition since there isn't any source to jump to, but there will be analysis available for built-ins, so you will see arity warnings, docstrings, etc probably

or maybe it does jump to definition for the deps it used for analysis, not sure.

cc @UKFSJSM38

It does if a bb.edn is available

Oh right!

Then bb deps would be on classpath provided by clojure-lsp

Lemme try that again

OK, so my mini-project looks like this

% cat bb.edn
{:paths ["bb"]}

% cat src/scrap.clj
#!/usr/bin/env bb

(require '[babashka.process :refer [sh]])
(def myname (:out (sh "whoami")))

(print myname)

Now if I move the point to sh and jump to definition, I get "No definitions found"

Shouldn't the :paths contain src and not bb?

Ah, yes 🙂 But it doesn't change anything

Could you check what is the classpath clojure-lsp is finding? In emacs there is the lsp-clojure-server-info command

Any idea on how to do that with eglot, which is what I'm using?

Or from the command line perhaps

Not possible with eglot AFAIK as this is a custom request. you can check server logs though

https://clojure-lsp.io/troubleshooting/#server-log

Ok, I'm looking at the server log now. Is this what you mean?

Almost, we need the classpath string, but it's probably using the cached classpath so it won't show on these logs, but if you delete .lsp/.cache it should show

It uses this deps.edn for this feature and process is missing because it's a git submodule of babashka. Please make an issue about it and I'll fix it. https://github.com/babashka/babashka/blob/master/resources/META-INF/babashka/deps.edn

Done https://github.com/babashka/babashka/issues/1454

It still doesn't work for babashka.fs/glob (or even clojure.core/print) but that's probably a problem with my emacs/lsp, not bb

can you try to make an arity error to see if it detects that?

with glob

Yeah that works fine - it's only the jump-to-definition that doesn't work

I also do get docs for it

maybe this is an eglot problem with jumping to definition into jars? I've heard about this before

Yes, I think so: https://github.com/joaotavora/eglot/issues/661#issuecomment-1307610635

Oh yeah, forgot about that eglot issue

Installing jarchive should fix it

Tried it, but it doesn't work for me https://github.com/joaotavora/eglot/issues/661#issuecomment-1362204524

can you try it with a regular jvm project to see if you can navigate into clojure.jar?

Will try tomorrow

A little tired now :) thanks yall for all the help

Alright, so it was a general eglot problem. https://clojurians.slack.com/archives/C099W16KZ/p1671706650817479
