Clojurians Log v2

Should the -M flag for Clojure CLI tools have an issue when also supplying -Sdeps options? (the -A flag works without issue for the same command)

/usr/local/bin/clojure -M:env/test -Sdeps '{:deps {}}' 

Execution error (FileNotFoundException) at java.io.FileInputStream/open0 (FileInputStream.java:-2).
-Sdeps (No such file or directory)

@jr0cket The -S... options should go before -M

clj-opts before exec-opts (although they are mentioned in the other order in the help text, that order is documented as Run main clojure [clj-opt*] -M[:aliases] [init-opt*] [main-opt] [arg*] )

(I've made the same mistake before)

Yes, putting the -M after -Sdeps does seem to work on the terminal. That ordering is not the case with -A flag and so sounds like a change is required for Cider to work correctly with jack-in. The ordering can be changed by editing the the command line each time, but using .dir-locals.el config to set the alias, the -M and -A flags are put before the -Sdeps option I assume -A will also work after -Sdeps option, to support those who havent upgraded to Clojure CLI tools

the same rules apply for -A

Start a REPL   clj     [clj-opt*] [-A:aliases] [init-opt*]

Except -A doesnt uphold that rule in practice...

It's a case of Hyrum's law, but I guess the tools doing it wrong should be changed.

Confirmed that editing the cider command line and putting -M flag in the correct place does work :)

/usr/local/bin/clojure -Sdeps '{:deps {nrepl {:mvn/version "0.8.2"} refactor-nrepl {:mvn/version "2.5.0"} cider/cider-nrepl {:mvn/version "0.25.3"}}}' -M:env/test -m nrepl.cmdline --middleware '["refactor-nrepl.middleware/wrap-refactor", "cider.nrepl/cider-middleware"]'

That's annoying. It looks like we'll need to write a parser for the arguments or something and split on it? Not too terrible, but it is if you want to be backwards compatible.

@dominicm I just submitted an issue for this on the cider repository https://github.com/clojure-emacs/cider/issues/2916

Hmm, I guess I'll have to check if my scripts use prefix or suffix form. That pattern is used in other tools too.

or just don't use cider-jack-in. I never use it.

I do. It's a useful tool, especially for beginners. Having less pieces to understand is very useful.

Having less magic to understand is also useful ;)

I also really like that CIDER can start up almost any project for you automatically without thought. It displays its startup command in the repl so you know there actually isn’t any magic. It’s just an extra dep and a main so you can run from the clj easily

There's no magic, just trying to build on top of simple tools underneath. It's more like an abstraction.

It feels like too much magic to me. Also I don't want the REPL to be a subprocess of my editor..

the subprocess part is fair 🙂 If there's a problem in your lisp interpreter from 1970 your repl goes down ...

Clojure tools (clj) https://clojure.org/releases/tools#v1.10.1.727 is now available: • Fix clj -X:deps tree adding tools.deps.alpha to tree • Fix clj -X:deps mvn-pom adding tools.deps.alpha to pom deps • Fix clj -X:deps git-resolve-tags not working • https://clojure.atlassian.net/browse/TDEPS-152 - Fix clj -X:deps mvn-install on jar to also install embedded pom • Fix clj -Spom not respecting dep modifications from -A (regression)

Is there any way to install dependencies from a given alias without running an associated :main-opts in the alias? Essentially I want a -e "" that ignores the main-opts

(specifically from the CLI, I realize its very doable via the clj package)

implementation detail, subproc part could change :)

Right now my best shot is using babashka to construct a new deps.edn and invoking clj -Sdeps

clj -Sdeps "`cat deps.edn | bb -I -e "{:deps (merge (:deps (first *input*)) (get-in (first *input*) [:aliases :native-image :extra-deps]))}"`" -e ""

@rschmukler (I don't think you need -I here, since you're reading only one EDN value)

cat deps.edn | bb -e "{:deps (merge (:deps *input*) (get-in *input* [:aliases :native-image :extra-deps]))}"

Right on! I misunderstood the CLI. I thought -I coerced to EDN from string literal

-I is for reading multiple EDN values from stdin

The official way is to use the -P option: https://clojure.org/reference/deps_and_cli#_prepare_for_execution

So clojure -P -M:my:aliases:here assuming you're using a recent release of the CLI.

@seancorfield perfection! Sorry that I missed that. Might be worth adding that to the clj --help docs too

It's in that help

exec-opts:
 -A:aliases     Use aliases to modify classpath
 -X[:aliases]   Use aliases to modify classpath or supply exec fn/args
 -M[:aliases]   Use aliases to modify classpath or supply main opts
 -P             Prepare deps - download libs, cache classpath, but don't exec

Then clearly my clj must be outdated lol!

Right'o - thank you for the help!

There we are

Yeah, 645 was one of the prerelease builds while a lot was changing in the CLI.

Now I've just gotta figure out why Manjaro hasn't kept up

Updated my clojure and sure enough, it's all there for me. Thanks again @seancorfield

Clojure CLI 1.10.1.697 is the minimum version for the -P and new mode for the -M flags. 1.10.1.727 is the latest (officially release today)

https://clojure.org/releases/tools for your version questions

I'll be glad when -A changes to no longer run :main-opts 🙂

I did a little cheat sheet of command line flags to help me remember https://github.com/practicalli/clojure-deps-edn#clojure-cli-main-flag-options

@alexmiller This is still the plan, at some point, right?

yes

I expect that to be ~months

When I run clj i get an exception about building the class path. I tried deleting my cpcache. If you can think of something else i can try please chime in. gist file is my deps.edn. the comment contains the command run and output (error): https://gist.github.com/drewverlee/893a150c780a86fbf73cd789b48d9b40 Thanks in advance. ill post in this thread if i figure it out.

#:com.datomic{ion-dev #:mvn{:version "0.9.276"}} the ion-dev does not begin with a colon but in #:mvn{:version it does. can you try fixing that?

scratch that. namespaced symbols look strange to me in that fashion 🙂

@jr0cket I see

Run the project	clojure -X:project/run -m domain.main-namespace

It is strange, I'll clean it up. But I'm guessing that's not it. That's from copy pasting

Also, you have

Package library	clojure -X:project/jars

I don't think that's it - this look like maybe a bad version range in some transitive dep?

although I know all those deps so not sure what you'd find there :)

{:deps      #:com.datomic{ion-dev #:mvn{:version "0.9.276"}}

typo: mvn/verison

Ah yes, on com.datomic/ion {:mvn/verison "0.9.48"}

newest version of clj will give you a better error message there
