[M4 Release] The new type system [message #991322]

Hello,

today Xtext 2.4.0M4 was released! Yahoo!

My question: Is the new super duper type system included into this build? I tried following simple example (adopted from the Sven's blog: http://blog.efftinge.de/2012/10/current-development-and-future-plans.html) and it doesn't compile.

val map = newHashMap
map.put(1, "")
val x = map.get(1)
println("Length: " + x.length)  <--- ERROR: The method length is undefined for the type Test

Should the new type system be activated in some way?

Thank you!

Regards,
Boris

Hi Boris,

the M4 does not include the new type system.

Regards,
Sebastian

Nevertheless, this testcase is green with the new not-yet-released
work-in-progress implementation:

assertEvaluatesTo("Length: 3",
"{\n" +
" val map = newHashMap\n" +
" map.put(1, 'abc')\n" +
" val x = map.get(1)\n" +
" println('Length: ' + x.length)" +
"}");

Hello Sebastian,

thanks for the info. Will you please make an announcement (e.g. in Twitter) when we can test it?

Regards,

As early as possible hopefully by the end of February, maybe March.
We will come up with a reliable release date in January.

Thanks for your patience.
