Deploying Overtone

[Folcon]

Hey,

I'd like to use overtone in one of my projects, deploying it to windows / mac / linux:

1. Are there any issues doing this?
2. Is there a way for me to only load the specific bits I need to synthesise sound or is using the live ns the recommended way?

3. How would I go about doing this?

   1. I tried to lein uberjar my project, but according to #140, I should skip :aot via: :main ^{:skip-aot true} example-project.core in project.clj. Doing so creates a jar that seems to contain no main class:

   $  java -jar example-project/target/example-project-standalone.jar
   Error: Could not find or load main class example-project.core
   Caused by: java.lang.ClassNotFoundException: example-project.core
   
   $  java -jar example-project/target/example-project-standalone.jar --main-class clojure.main -m example-project.core 
   Error: Could not find or load main class example-project.core
   Caused by: java.lang.ClassNotFoundException: example-project.core

   2. Do I need to do anything specific to bundle SuperCollider, or will the internal SuperCollider server be enough?

Thanks!

Hi @Folcon , can you explain a bit more what the use case is in your case of running off an (uber)jar?

I'm going through old issues now that some of the more prominent issues have been fixed. I'd have to do some testing to figure out how to bundle Overtone in the best way, maybe we can gather up some tips in the wiki. Based on the above I can give you some input.

• We no longer bundle our own SuperCollider, the user is expected to have it installed (see https://groups.google.com/g/overtone/c/qndjDV5FS9Y for motivation)
• Overtone can not be AOT compiled, because it does too much stuff at load/compile time that really needs to be done each time it starts. That's just how it's been architected, since it's primarily intended for live coding.

java -jar example-project/target/example-project-standalone.jar --main-class clojure.main -m example-project.core 
Error: Could not find or load main class example-project.core
Caused by: java.lang.ClassNotFoundException: example-project.core

I think what's happening here is that Java is interpreting -m example-project.core, overriding the preceding --main-class option. Try making it explicit that these are really options for clojure.main, by adding an --.

java -jar example-project/target/example-project-standalone.jar --main-class clojure.main -- -m example-project.core

Well I was trying to see if I could use overtone to author some dynamic soundtracks with the goal of bundling them in a game. IE depending on what action is happening in the game, create and play appropriate music.

Based on what you're saying this may not be workable?

I think something like FMOD is useful for game audio. Or, you could make use of Minim Java library via Clojure interop, depending on licensing requirements, that is. Never tried the latter, have used the former. Also, since Overtone depends on SuperCollider, you will possibly have an unnecessary hard time bundling it within your game. Other options are MaxMSP or PureData, but then Clojure is no longer relevant, I'd think. Just a couple of cents.
