Run koans in "non-interactive" mode

yeah it totally can, in fact - that's how it used to work back when i started it. i doubt this is that difficult, i'll leave this open and see if i can get it implemented easily. i really don't think it'd take too much, just need to pull out of my memory the best place to implement that.

Great. Let me know if there is anything I can do to help develop or test this functionality.

@DavidWhitlock sorry about the delay, life's been hectic to put it mildly. Here's what I'm thinking tell me if this works for you.

The build is currently in ant (probably another issue I should log :)), I'm thinking adding a target to:

1. compile all the koans
2. update all the file "hashes" to indicate no compilation is necessary
3. set system property to disable the "press Q" behavior
4. run the koans w/ the existing runner

This will just indicate to your grading suite/script success/failure like it does today, not necessarily which koan failed (though that'll be written to stdout).

Right now the time consuming part is compiling every single koan class incrementally. This definitely speeds up interactive koans, but if you just want to "let it rip" there's a ton of overhead associated w/ each compile phase that when summed together yields an awful lot of waste. If you think knowing which koan failed (ie a return code 1 for first koan failed, 2 for 2nd, etc. and 0 for all succeed) I can alter step 4.

I'll count on running with this, but let me know if you can think of something w/ more reuse and efficiency or that would work better.

Hey, @matyb. Thanks for getting back to me.

That sounds like a fine plan. Running with a system property will work for me and I don't mind a slower compile process as long as the JVM exits at the end. Printing out which koans failed is fine with me. I don't need the JVM's exit code to reflect the number of failures. A non-zero exit code would be cool if any test failed, but it's not necessary.

Thanks again!

Dave

@DavidWhitlock added an "interactive" mode to koans/app/config/config.properties, feel free to flip that to false to enable the behavior you seek.

Hope this helps. Let me know if you find problems.

[DavidWhitlock]

Thanks, @matyb. I'll check it out this weekend.

[DavidWhitlock]

The changes look good, @matyb. They will help my automated grading process a lot. Thanks again!

Great to hear @DavidWhitlock, thanks for following up
