#shadow/env not working in ~/.config/shadow-cljs/config.edn?

[glyh]

For now I have to do:

{:maven
 {:local-repo "~/.cache/m2"}}  

Instead of

{:maven
 {:local-repo #shadow/env "$SHADOW_MVN_REPO"}}  

And I'll also have to set the envrionment variable SHADOW_MVN_REPO outside cause config.edn doesn't allow me to concat strings.

Is there a more ergonomic way to set m2 dir?

I saw this https://www.reddit.com/r/Clojure/comments/13vrrl0/leiningen_moving_the_maven_local_repository/ where people use #= to get work done but that doesn't seems to work with shadow-cljs.

[glyh]

I'm looking for information about #= but seems like github is broken and I can't find matches in discussion. Only refernce I got is 2 match on lein code base.

I think this might be somewhat overkill for configuration but I think we may at least have something like templates in bash?

#shadow/env should work fine, but note that it should likely be #shadow/env "SHADOW_MVN_REPO", so without the $.

And maybe you want to use a default value for cases where the env var isn't set?

{:maven
 {:local-repo #shadow/env ["SHADOW_MVN_REPO" :default "~/.cache/m2"]}}

#= is the eval reader, it is generally advised to not use it. shadow-cljs also doesn't support it anywhere.

[glyh]

Yeah that looks like it. Also it's annoying that when using npm it cleans my environment variable and I have to use something like this:

$ cat .env
XDG_CONFIG_HOME="$HOME/.config"
SHADOW_MVN_REPO="$HOME/.cache/m2"
$ cat ~/.config/shadow-cljs/config.edn
{:maven
 {:mirrors 
  {"central" {:name "Aliyun"
              :url "https://maven.aliyun.com/nexus/content/groups/public/"}
   "clojars" {:name "USTC"
              :url "https://mirrors.ustc.edu.cn/clojars/"}}
  :local-repo #shadow/env ["SHADOW_MVN_REPO" :default "~/.cache/m2"]}} 

to get things working, is there a workaround?

[thheller]

I don't really understant the question. Workaround for what?

shadow-cljs on its own does not look at .env files, so I'm assuming you have some sort of shell support for that?

You might have more luck overall using deps.edn for this. It has a cleaner handling for all maven related configs as far as I know. Or if you have a solution for leiningen then you can just use that.

Sorry I should add another file here: package.json

{
  ...
  "scripts": {
    "dev": "source ./.env && shadow-cljs watch main renderer",
    "build": "shadow-cljs compile main renderer",
    "clean": "rm -rf resources/public/js/* && rm -rf target"
  },
  ...
}

npm script cleans my environment variables so I have to do source .env. I'll take a look at lein and deps.edn. Thanks for your paitience.
