2. Effort is put into creating more complete LEP implementations for different CL's so that ELI can be used effectively on multiple CL implementations. The benefit of this option is that ELI is very full-featured as it is and just the port of the underlying communication layer would need to be done. Also, since the largest commercial CL vendor supports ELI and actively enhances it, we can take advantage of both commercial and open source development efforts.

As far as I understand it, LEP won't work on non-threaded lisps, which means there will always be room for a solution that doesn't require threading. Of course taking advantage of it where present is great, but right now SBCL lacks threads on anything but x86.

If you want to help out, I'm sure that we'd take any code patches towards getting gencgc working on PowerPC - it's not a trivial matter

and in the meantime I enjoy having a development environment

I may be wrong, but my understanding was that: 1. ELI uses a socket for communicating between Emacs and CL. 2. The CL implementation, on getting a message on the socket, launches a thread to service the request. This allows multiple request to be submitted to the underlying CL implementation. On a non-threaded lisp, this (of course) would not be possible since the CL implementation couldn't spawn off multiple threads. Instead, it would block until able to complete the request and return the result to Emacs. This would be equivalent to what happens under comint mode (and, presumably, SLIME). However, if my understanding of how LEP functions is correct, this wouldn't mean that you couldn't port ELI to a non-threaded CL, just that you wouldn't realize the benefits of threads. though, My development environment is MS Windows. that works on SBCL/OS

X.

Sure. I enjoy having a development environment too. -- Bill Clementson __________________________________ Do you Yahoo!? Free Pop-Up Blocker - Get it now http://companion.yahoo.com/
