Hello, I have a question, hopefully easy, but I can't seem to find the answer. I'd like to evaluate a region which contains something like this: (asdf:load-system '#:foo) (in-package #'foo) and have my slime REPL actually change its current package. I realize that some problems can happen with the above, which led me to this page: http://stackoverflow.com/questions/27095320/common-lisp-how-to-get-in-packag... When I rewrite the above to (eval-when (:compile-toplevel :load-toplevel :execute) (asdf:load-ssytem '#:foo)) (in-package #'foo) It loads the package, but can't change the current REPL package to it, SLIME continues to say CL-USER. I also realize that slime may be LOADing the file, which preserves the current package. Since I get a => <PACKAGE "FOO"> in my *slime-events* buffer I think that may be also happening. Is there any way to change the current REPL package by using any SLIME evaluation methods that involve evaluating a region? Or must I either manually type (in-package :foo) in the REPL or use the ,in-package SLIME command helper. I'm just about to write some elisp to take the region, find the slime repl buffer, manually append the region into the REPL buffer, and enter a return to execute it! There must be a better way! Thank you! -pete
