I understand why your are doing this, but it must be a ton of work, and has a lot of potential for introducing bugs that do not exist in the D code base.

Someone proposed that we compile D to JVM bytecode, but maybe we should have D compile to C or C++ source code instead, at least that can work fully unlike with JVM bytecode, and it would save you guys a lot of work

I wonder how good the implementation will be if one just pass the line to rdmd and prints the result.

I'm assuming you're talking about REPL. That won't cut it, as one wants to keep maintain a notion of state (variables in memory etc) and not reparse lines entered everytime (which could have IO side effects etc).

I've played a bit with Oskar Linde's library for that and ported it to latest DMD release and it works quite well already, something solid to build upon (see post http://forum.dlang.org/thread/fpmpa6$2muq$1@digitalmars.com).

Try it, rdmd has --eval and --loop. It's useful but not as good as a real REPL.

I'll give that a try, thanks.
