Re: [scala-tools] Plugins

I remember running into an issue where StdPhase was not visible from the package I was using. I simple extended Phase (has the same constructor as StdPhase), and kept moving along.

If you want an example of creating/testing a scalac plugin (using maven), check out: http://github.com/jsuereth/osgi-scalac-plugin/tree/master

I hope to finalize that project if/when I start using OSGi in production again.

Hi David

The code in the examples should work for 2.7.x and the code needed for
2.8 (trunk) is shown in comments in the examples.

What is the error ?

I copied and pasted the code from http://www.scala-lang.org/node/140

When I compiled:

dpp@yak:~$ scalac Foo.scala
Foo.scala:24: error: not found: type StdPhase
  private class DivByZeroPhase(prev: Phase) extends StdPhase(prev) {
   ^
Foo.scala:21: error: type mismatch;
found : DivByZero.this.DivByZeroPhase
required: scala.tools.nsc.Phase
   def newPhase(prev: Phase) = new DivByZeroPhase(prev)
   ^
two errors found
dpp@yak:~$

Thanks,

David
