util-eval refers to classes that are removed or deprecated in scala 2.11.x about util HOT 10 CLOSED

I think we might have removed util-eval from being tested. We're going to stop supporting it in scala 2.11 (at least I think that is the current plan).

Ah, OK. I have a use-case for eval, but I can fork it if eval won't be part of twitter util going forward. Feel free to close this issue, or let me know if I should do it.

I'm not opposed to keeping util-eval around if somebody wants to do the work to forward-port it to the 2.11 compiler interface, but at Twitter we're trying to migrate everyone off of it in favor of other configuration mechanisms.

ScalaObject is now replaced in the develop branch, and we'll be publishing util-eval for 2.11 soon.

Do you guys have a test for the case where invalid code is compiled? I've an error on my project that is inspired from util-eval and even if I think that the error is mine, I wanted to check...
Here is the error that I get: BuggleInc/PLM#421

from util.

do i understand it correctly that util-eval will be made available for 2.11?
thats good news

i would be curious to know what other configuration mechanisms are preferred over util-eval. i did not realize it had fallen out of favor. we use it extensively for runtime compilation of classes...

thanks

@koertkuipers we generally suggest that folks use the flags API instead. It can be found in util-app, and it's described in the TwitterServer docs. If you're using flags, we generally recommend that you use TwitterServer.

@mosesn
i assume you already fixed util-eval up for scala 2.11, because i got the tests for it to run just fine in with one change in Eval.scala:

   private lazy val libPath = try {
-    classPathOfClass("scala.ScalaObject")
+    classPathOfClass("scala.AnyVal")
   } catch {
     case e: Throwable =>
       throw new RuntimeException("Unable to load scala base object from classpath (scala-library jar is missing?)", e)

from util.

@koertkuipers Yep, see this commit in develop.

great! i was looking on the wrong branch :(
glad to see its back. if it no longer has importance inside twitter i will
look around for alternatives (scala Toolbox comes to mind) but for now we
love this tool to run quick jobs from text files (in scalding and spark),
and for Scala DSL config files, which we use extensively (i still like it
way better than json or yaml).

happy to help out next time it needs to get migrated.

best, koert
