Summary: custom initialisers lost during partial recompile

Initial Comment:
Class initialisers in packages which have not changed,
and are hence not recompiled, are lost when other
packages are compiled.

Nice compiler version 0.9.2 (build 2003.09.02, 21:54:27
UTC)

----
package A;
class A {
    {
      println("init A");
    }
}

package B;
import A;

void main(String[] args) {
  let a = new A();
  println("done!");
}
----

The printing of many expressions has been fixed, as of
0.9.3, so this should rarely/never happen now.
Keeping the bytecode should still eventually be implemented.

I'd agree with keeping the existing bytecode.

This isn't a blocker because I just compile with -R and the
extra time isn't too excessive.

I have fixed the printing of these expressions (not commited
yet). However, I think a better solution would be not to
print the initializer in package.nicei, but to preserve the
bytecode generated one.

Is this holding you back?

change A/a.nice into

package A;
class A {
    {
      let b = true;
      if (b) {
        println("init A");
      }
    }
}

and the generated package.nicei includes (with my
annotations as to the errors)

class A {
{
{
if(b)  // compiler throws 'b is not declared' after error
below is fixed
{
println("init A");
}

else
()  // compiler throws 'Encountered ")".' here --> change to {}
endif;
}
}
}

This bug has been fixed. The next release of the compiler will
include this correction. In the mean time, I encourage you try
the development version. It contains a version of the compiler
that fixes the bug. Please try it and reopen the bug-report if
you find any problem with it.

To know how to get an install the development version of the
compiler that fixes this bug, please read
http://nice.sourceforge.net/cgi-bin/twiki/view/Dev/DevelopmentVersion

Thanks again for your help by submiting this bug report.
