[asdf-devel] printing the symbol asdf:defsystem for .asd file
So I am using ASDF 2.31 which puts the symbol "defsystem" into asdf/defsystem package instead of plain asdf package (Franz already includes ASDF 2.31 in their patches for Allegro CL). I have a little utility which emits the .asd files for me, with a form like: `(asdf:defsystem ,(something-to-make-my-system-name) :description "blah" … ) and now the asdf:defsystem symbol is coming out as asdf/defsystem:defsystem instead, which makes the .asd file non backwards-compatible with slightly older asdf versions, because (symbol-package 'asdf:defsystem) --> #<The asdf/defsystem package> So the Question is, what is the best way to get asdf:defsystem to print as asdf:defsystem, when its home package is :asdf/defsystem and apparently it is now just re-exported from :asdf. Or should this symbol now be officially printed as asdf/defsystem:defsystem ? Or should I put some (in-package ...) statement at the top of the .asd file, and use plain defsystem with no package prefix? Of course I think for the time being the .asd file should be compatible with all ASDF versions from recent history... -- My Best, Dave Cooper, Genworks Support david.cooper@genworks.com, dave.genworks.com(skype) USA: 248-327-3253(o), 1-248-330-2979(mobile) UK: 0191 645 1699

If you print that form while *package* is bound to something that uses ASDF, (such as ASDF-USER, on 2.31), then it will omit the prefix.

In ASDF1 and ASDF2, indeed, .asd files are read from a temporary package ASDF~D that uses ASDF.

You already needed to, to be able to name, modify or redefine them afterwards.

I don't want it to omit the prefix. I want: (asdf:defsystem ...)

Does "usual hygiene rules" mean that I do or do not need any prefix on the defsystem in (defsystem ... ) ?

You do NOT need the prefix, unless you've explicitly changed package to one that doesn't :use :asdf. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org Individualism is thus an attitude of humility before this social process and of tolerance to other opinions, and is the exact opposite of that intellectual hubris which is at the root of the demand for comprehensive direction of the social process. — Friedrich August Hayek, The Road to Serfdom

I'm not seeing any difference in SLIME's indentation between: (defsystem #:gdl-ent :description "Auto-generated asdf defsys from Genworks GDL cl-lite." :author "Genworks and Dave Cooper unless otherwise indicated" :serial t :version "2013030200" :depends-on (:gdl-build) :components ((:file "source/package") (:file "source/assembly") (:file "source/controller") (:file "source/agent"))) and: (asdf:defsystem #:gdl-ent :description "Auto-generated asdf defsys from Genworks GDL cl-lite." :author "Genworks and Dave Cooper unless otherwise indicated" :serial t :version "2013030200" :depends-on (:gdl-build) :components ((:file "source/package") (:file "source/assembly") (:file "source/controller") (:file "source/agent"))) This is with no (in-package ...) form at the beginning. In any case, it looks like as long as the .asd files are used as intended, then no package prefix is needed on the (defsystem ...), and no (in-package ...) is needed at the top (when using any ASDF version). I think the confusion started at a time when we were, for some reason, manually loading .asd files ourselves by calling (load ...), which according to my understanding is not and has never been an intended use of .asd files -- they are strictly to be considered as data files for use with supported ASDF (and Quicklisp) operators which expect to find .asd files. Although normal CL expressions are also allowed inside .asd files, the .asd files are never intended to be loaded with (load ...) by the user.

Yes. I recently modified SLIME to do the right thing when you C-c C-k a .asd file, i.e. (asdf:load-asd pathname) Note that load-asd is an ASDF3-ism. Later ASDF2 versions only have a slightly less practical load-sysdef, and ASDF1 doesn't expose any separate abstraction for that. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org Our system is defined to prevent majority politicians from overtly oppressing minorities.

Not for me - I had problems with indentation when using plain (defsystem ...) and no problems with (asdf:defsystem ...), so I always used the latter. Zach
