Working on MSYS2!

[jdf-id-au]

Hi everyone,

I'm working on a slightly unholy setup for a new Windows 10 Enterprise computer to which I don't have admin access.

I was able to install MSYS2 in userland, and emacs within that. px helped abstract away the NTLM proxy.

clj-msi also allows userland installation, and openjdk can just sit in a directory with JAVA_HOME pointing at it from msys2 (e.g. /c/Users/username/local/jdk-23.0.1/).

I was able to get cider working just by adjusting the default cider-jack-in command. I thought I'd share it in case anyone else needs such a cursed setup :)

cider-jack-in defaults to using PowerShell with -encodedCommand. This erroneously presented a Windows "How do you want to open this file?" dialog and didn't work. Decoded:

$PSNativeCommandArgumentPassing = 'Legacy'; clojure -Sdeps '{:deps {nrepl/nrepl {:mvn/version ""1.3.0""} cider/cider-nrepl {:mvn/version ""0.50.3""} mx.cider/tools.deps.enrich-classpath {:mvn/version ""1.19.3""}} :aliases {:cider/nrepl {:main-opts [""-m"" ""nrepl.cmdline"" ""--middleware"" ""[cider.nrepl/cider-middleware]""]}}}' -M:cider/nrepl⏎

I was able to use cider-jack-in normally with a lightly edited version of the decoded command:

clojure -Sdeps '{:deps {nrepl/nrepl {:mvn/version "1.3.0"} cider/cider-nrepl {:mvn/version "0.50.3"} mx.cider/tools.deps.enrich-classpath {:mvn/version "1.19.3"}} :aliases {:cider/nrepl {:main-opts ["-m" "nrepl.cmdline" "--middleware" "[cider.nrepl/cider-middleware]"]}}}' -M:cider/nrepl

Hope this is of use to someone!
