Clojurians Log v2

Clojure.Main is not on your PATH

try this

FROM 

RUN apt-get update \
    && apt-get install -y wget unzip

RUN dotnet tool install --global --version 1.12.0-alpha7 Clojure.Main

RUN apt-get clean \
    && rm -rf /var/lib/apt/lists/*

CMD ["/root/.dotnet/tools/Clojure.Main"]

you can run the stable version too, but then you’ll need a base image that provides version 6 of .NET

I’d go with the latest alpha 🙂

Thanks! Now I get the REPL prompt!

A bit late to the party but I came here say you can run dotnet tools like this: dotnet tool run Clojure.Main .

environment variable CLOJURE_LOAD_PATH is the equivalent.

The equivalent to the classpath? I tried this now:

user=> (System.Environment/GetEnvironmentVariable "CLOJURE_LOAD_PATH")
"/my_clojureclr_project/test:/my_clojureclr_project/src:/my_clojureclr_project/dev-resources:/my_clojureclr_project/resources:/my_clojureclr_project/target/classes:/root/.m2/repository/org/clojure/clr/tools.nrepl/0.1.0-alpha1/tools.nrepl-0.1.0-alpha1.jar:/root/.m2/repository/org/clojure/clr/tools.reader/1.3.7/tools.reader-1.3.7.jar:/root/.m2/repository/nrepl/nrepl/1.0.0/nrepl-1.0.0.jar:/root/.m2/repository/org/nrepl/incomplete/0.1.0/incomplete-0.1.0.jar"
user=> (require '[clojure.tools.nrepl])
Execution error (FileNotFoundException) at System.Diagnostics.StackFrame/ (NO_FILE:0).
Could not locate clojure/tools/nrepl with extensions .cljr, .cljc, .cljr, .cljr.dll, .cljc.dll, or .clj.dll on load path.

A big part of the problem here is that I do not know what I am doing. It was 15 years ago since I did anything .Net.

(I created that load path using Leiningen.)

The code for breaking down the components of the CLOJURE_LOAD_PATH is

string rawpaths = (string)System.Environment.GetEnvironmentVariable(ClojureLoadPathString);            
 string[] paths = rawpaths.Split(Path.PathSeparator);

System.IO.Path/PathSeparator

Are you still doing this out of Docker? Getting paths right in that circumstance is beyond my knowledge.

Still in Docker, yes. Am I supposed to be able to do lein run?

What do I do with the paths once I have separated them?

Ah, so that’s the code that ClojureCLR uses?

user=> System.IO.Path/PathSeparator
\:
user=> 

The path looks cool to me.

# ls /root/.m2/repository/org/clojure/clr/tools.nrepl/0.1.0-alpha1/
_remote.repositories               tools.nrepl-0.1.0-alpha1.pom
tools.nrepl-0.1.0-alpha1.jar       tools.nrepl-0.1.0-alpha1.pom.sha1
tools.nrepl-0.1.0-alpha1.jar.sha1

Lein runs in java land and knows how to use maven, read poms, grok jars. That's what is doing in the background to get the code in your local cache. ClojureCLR can't handle all that. (which is why i'm working feverishly to port tools.deps -- then we weill be able to get automatic pulls of dependencies from git repos and nuget.) For now, I'd just clone the repo into someplace nice and have the path include something-nice.../src/main/clojure . And wish me speedy success on porting tools.deps.

Wishing you speedy success!

Clone what repo? The nrepl one?

nrepl and whatever it depends on.

I tried with installing Leiningen in the container and can adding a project.clj, using the :main.cmd to launch the nrepl server. But this is probably not the way to go. Leiningen is run by Java and and complains.
