I'm attempting to make a Lisp package with uiop/package:define-package. I'm using SBCL, and have confirmed that package-local nicknaming ought to be supported:
* *features*
(:QUICKLISP :ASDF3.3 :ASDF3.2 :ASDF3.1 :ASDF3 :ASDF2 :ASDF :OS-UNIX
:NON-BASE-CHARS-EXIST-P :ASDF-UNICODE :X86-64 :GENCGC :64-BIT :ANSI-CL
:COMMON-LISP :ELF :IEEE-FLOATING-POINT :LINUX :LITTLE-ENDIAN
:PACKAGE-LOCAL-NICKNAMES :SB-CORE-COMPRESSION :SB-LDB :SB-PACKAGE-LOCKS
:SB-THREAD :SB-UNICODE :SBCL :UNIX)
* (uiop:featurep :package-local-nicknames)
T
Nevertheless, when I try to define a package that has local nicknames, it doesn't work:
(uiop/package:define-package #:foo
(:use #:cl)
(:local-nicknames (#:b #:binparse)))
debugger invoked on a SIMPLE-ERROR in thread
#<THREAD "main thread" RUNNING {1001878103}>:
unrecognized define-package keyword :LOCAL-NICKNAMES
Type HELP for debugger help, or (SB-EXT:EXIT) to exit from SBCL.
restarts (invokable by number or by possibly-abbreviated name):
0: [ABORT] Exit debugger, returning to top level.
(UIOP/PACKAGE:PARSE-DEFINE-PACKAGE-FORM #:FOO ((:USE #:CL) (:LOCAL-NICKNAMES (#:B #:BINPARSE))))
source: (ERROR "unrecognized define-package keyword ~S" KW)
0] 0
(binparse being another package I've made, which worked fine, but which did not happen to use local nicknaming).
What I've found of the uiop/package source seems to indicate that this shouldn't happen? Going by that, it should either work, or have a specific error message indicating the non-supported-ness of local nicknames (if somehow uiop:featurep is inaccurate or changing), but it shouldn't give a generic unknown-keyword error. At this point I'm not sure what I could be getting wrong.
