Hi Ary and All,

I am suffering from an IDE exception recently. 

The log info looks as follows:

----------------------------------------------------------------------
!ENTRY org.eclipse.core.jobs 4 2 2009-10-19 14:33:17.381
!MESSAGE An internal error occurred during: "Requesting D AST from

----------------------------------------------------------------------

Does anybody know why?
I am using openSUSE 11.1 + Eclipse 3.5 + Descent (latest SVN-checkout)


Best regards

Hi Qian Xu,


What's the D source code for that exception to be thrown?

I cannot remember right now, but I am sure it was while typing.

BTW: The code block within a "version" statement, cannot be folded. I regard
this as a small bug. ^^)


Best regards,

Right now it happened once, when I switched the focus back from KNode (the
news reader program) to Eclipse.

The error is the same. The dialog said: 

'Requesting D AST from selection' has encountered a problem. 
An internal error occurred during: "Request D AST from selection".

Sorry, without the source code I will not be able to reproduce it. :-(

I think it can be anything.

For instance, I just tried to modify this code block

    char[] jsonstring;
    void emit (char[] s) {jsonstring ~= s;}
    json.print(&emit);

I moved cursor after "print(" and then typed "func".
I saw this exception again.

Hi Qian Xu,

I uploaded a new version. Can you update and see if the error is gone?
