hm, I can't seem to get clojure -Mxxx --eval to work.

; clojure -Mrebel --eval "(require '[clojure.repl :refer [doc]])"
The following errors occurred while parsing your command:

Unknown option: "--eval"

the help message says this should work ok:

Usage:
  Run main      clojure [clj-opt*] -M[aliases] [init-opt*] [main-opt] [arg*]
init-opt:
 -e, --eval string   Eval exprs in string; print non-nil values

what am I doing wrong here?

For Rebel Readline I define an alias in my user level Clojure config https://github.com/practicalli/clojure-cli-config/blob/87ff98610531522d43b6fa8fb6fd1b71940e205c/deps.edn#L159

:repl/rebel
  {:extra-deps {nrepl/nrepl                {:mvn/version "1.5.1"}
                cider/cider-nrepl          {:mvn/version "0.58.0"}
                com.bhauman/rebel-readline {:mvn/version "0.1.5"}}
   :main-opts  ["--eval" "(apply require clojure.main/repl-requires)"
                "--main" "nrepl.cmdline"
                "--middleware" "[cider.nrepl/cider-middleware]"
                "--interactive"
                "-f" "rebel-readline.main/-main"]}

Then call clojure -M:repl/rebel The --eval part of the alias definition loads things like add-libs. As sean mentions, I use the built-in doc key mapping thar Rebel provides.

WARNING: Use of :main-opts with -A is deprecated. Use -M instead.
The following errors occurred while parsing your command:

Unknown option: "-e"
Unknown option: "-m"

i ended up just bypassing the shell script altogether and invoking the jar file directly.

if it helps, I found that the clojure shell script is running java -classpath /home/jyn/.m2/repository/org/clojure/clojure/1.12.0/clojure-1.12.0.jar clojure.main -m rebel-readline.main --eval ...; if i switch the order of --eval and -m in that invocation, things work ok. but i don't know how to convince the shell script wrapper to do that.

-Mrebel should be -M:rebel BTW. But that means that it will run clojure.main (as you can see), passing -m rebel-readline.main as the "main namespace" argument to clojure.main/-main (the Main-Class). Anything following that is arguments to the main function you are invoking (i.e., rebel-readline.main/-main). You want --eval (`-e`) to be passed to clojure.main, so you need it before the -m rebel-readline.main argument (which is supplied by your alias :rebel), so you can't do it like that...

This is a limitation of :main-opts in your :aliases.

Try clojure -A:rebel -M -e "(require '[clojure.repl :refer [doc]])" -m rebel-readline.main I'm not certain that will work -- it kinda depends on what Rebel Readline does -- but I'll also note that Rebel Readline offers it's own way to show docs: ^X ^D which will show the docs for the symbol at the cursor.
