Scala for NetBeans Screenshot#12: Better Completion with More Types Inferred
>>> Updated May 11
Mostly, infix expressions can be type inferred now. CTRL+Click on infix op name, it will bring you to declaration (since 1.0.29.0)
===
Well, the type inference work is not so easy (with performance in mind), but anyway, I've got a bit more progress, at least, the chained member call can now be correctly inferred in a lot of cases. It's some level as Tor's JavaScript for NetBeans now.
First, let's create a val "node", which is a "scala.xml.Node"
Then, input '.' to invoke completion, as I know which type is of "node", the proposal items look good.
I choose "descendant" function (which returns a "List"), and input '.' again, we can see the proposal items look still good.
These features also work on Java's class.
Known issues:
- It seems the indexing/scanning for Scala standard library source will perform twice when you first installed Scala plugins
- The type inference is not consistence yet, so don't be strange for the strange behavior sometimes
Again, don't forget to download scala standard library's source jars and unzip to $SCALA_HOME/src, per sub-folder per jar
