Confirmed to be broken in the current source.
@sampottinger it looks like this was broken back in alpha 1, did you have it working properly?
Tracked down to 51145a8, though unfortunately that's the monolithic commit for the JDK support, ANTLR updates, etc, so it's still hard to know if this is a large problem or just something overlooked.
The internal issue is that javaCode
is not being set when the code cannot compile, which for code completion is always the case. So there's a NullPointerException
when that's accessed, and no completions are available. Hoping that there's a simple fix to get the incomplete code assigned to the variable, and we can get this working again.
Hey there! It appears that antlr gives up before it can apply the text transformations. I have a branch over at #219 that demonstrates allowing the the text transformation process to continue. That said, antlr does appear to throw out a lot before it is able to recover from a syntax error and my demo only works with the semicolon included at the end. Still working on that.
Phew, working again. Thanks @sampottinger!
(This will be in for the release that comes after alpha 5; which will be called alpha 6 or beta 1.)
