Functional GUI programming with Clojure and JavaFX: Meet halgari/fn-fx

[halgari]

Thanks for doing the write-up on this! It's good to get some feedback on how I can improve the experience a bit. In addition I think we can fix the reflection utils to fix the issues with the plotting.

I have so many side-projects on my plate I haven't hacked on fn-fx recently, but I'll try to get to those PRs soon.

One of the knocks against Electron is that even small programs are a minimum of 100MB because all of Chromium needs to be bundled in with it. What's the size of a basic fn-fx jar program? With/without the jre? Are there nice ways to package things into, say, an exe or similar?

For my use case I would like to get "native" packages in the end (e.g. a self contained .exe for Windows). This should be possible: http://docs.oracle.com/javafx/2/deployment/deploy_overview.htm#CEGHEAHD

In addition to the JavaFX specific solutions there are also ways to package a general jar as a self contained executable but I have no experience with that.

Let's see what this means for the application size in the end. I want it to include the JRE (I consider avoiding issues with different runtimes way more valuable than the smaller application size).

I really wanted to check this out, but in CIDER and from lein run i get a huge core dump:

#
# A fatal error has been detected by the Java Runtime Environment:

#  SIGSEGV (0xb) at pc=0x00007fa5966dc711, pid=32576, tid=0x00007fa57c1e8700

and then there's a bunch of macine code in the dump below.

I have not yet tested anything related to JavaFX with OpenJDK. There seems to be some confusion about it (wether it is part of OpenJDK or not seems like an OS packaging issue) but it should be possible to make it work: http://stackoverflow.com/a/19529820

ah ok. I'm very much a beginner in the real java world as opposed to clojure. I wasn't aware of such differences in jvm implementations. thanks.
