Anyone using com.redhat.ceylon.compiler.java.runtime.Main programmatically?

[Stephane Epardaud]

As opposed to from a Java command?

I'm thinking of making `main` catch exceptions and exit with an error code, because the JVM makes this undefined.

This API was never meant to be called programatically, but perhaps some people do?

I'm a bit wary of introducing `System.exit` calls as we've been bitten by them quite often in the past, but I think that in a `main(String[])` method when there's an exception throw by the main thread, that's the right thing to do. It allows the process callers to know something went wrong. At least with the main thread.

Can “main” then be made to be a small wrapper around some other method that can be used programmatically? Or maybe it’s already this way.

I suppose I can, but there's mostly stuff about parsing the arguments, which already call `System.exit` if they're wrong. I don't see how it's useful for API users. Those will already use the API part. Preferably `CeylonToolProvider` actually. This is really only meant to be used from the command-line.

Ah forget it, something else was in fact catching my exception, I don't think `Main` is to blame.

I see. Makes sense. To your original question, I don’t recall how I was using Main, when I was using it.
