MADEIRA-PORT #
hacking, May 8th 2012
This isn't Madeira proper yet, but something small and useful on it's own, I hope: MADEIRA-PORT.
Main feature is :MADEIRA-PORT ASDF component class:
(defsystem :foo
:defsystem-depends-on (:madeira-port)
:serial t
:components
((:file "package")
(:module "ports"
:components
((:madeira-port "sbcl" :when :sbcl)
(:madeira-port "ccl" :when :ccl)
(:madeira-port "ansi" :unless (:or :sbcl :ccl))))
(:file "foo")))
The :WHEN and :UNLESS options support an extended feature syntax, which allows things such as:
(:find-package :swank) (:find-function #:exit :sb-ext)
This extended feature syntax is also accessible by calling EXTEND-FEATURE-SYNTAX at the toplevel, after which regular #+ and #- readmacros will also understand it — but unfortunately they will also lose any implementation specific extensions in the process.
Happy Hacking!
