It WORKS!!!!!!!!! This is really cool. I put the call to the
MainGenericRunner.main function in a thread object and called start
(). I then did an import of my class and called a function and voila,
it returned the expected value while the lift program is running in
the other thread. Poor man's debugger without having to add print()
all over your code!
So below is the complete sequence. Thanks to Josh and Tyler for their
support!
% mvn scala:console
scala> import scala.tools.nsc.MainGenericRunner
scala> import org.codehaus.classworlds.Launcher
scala> new bootstrap.liftweb.Boot().boot
scala> val args = List("-howtorun:object", "-Dclassworlds.conf=/usr/
local/apache-maven/apache-maven-2.0.9/bin/m2.conf", "-Dmaven.home=/
usr/local/apache-maven/apache-maven-2.0.9",
"org.codehaus.classworlds.Launcher", "jetty:run").toArray
scala> object ConsoleThread extends Thread { override def run =
MainGenericRunner.main(args)}
scala> ConsoleThread.start()
scala> <type in your debugging code here!!!!>
