Inspecting logical pathnames with SLIME's inspector appears to fail. Test case: (setf (logical-pathname-translations "FOO") '(("FOO:**;*.*.*" "/foo/**/*.*"))) C-c I #p"FOO:bar;" RET #<SB-KERNEL:LOGICAL-HOST "FOO"> fell through ETYPECASE expression. Wanted one of (CONS STRING NULL). [Condition of type SB-KERNEL:CASE-FAILURE] Backtrace: 0: (SWANK::INSPECTOR-CONTENT-FOR-EMACS ("Namestring" #1=": " (:VALUE "FOO:BAR;") #2=(:NEWLINE) "Physical pathname: " #1# (:VALUE #P"/foo/bar/") #2# "Host: " #<SB-KERNEL:LOGICAL-HOST "FOO"> ...)) 1: (SWANK::INSPECT-OBJECT #P"FOO:BAR;" #<SWANK::FANCY-INSPECTOR {15EB7981}>) [...] Cheers, Michael
