[asdf-devel] recursiveness of :FORCE
by Tobias C. Rittweiler 09 Nov '09

09 Nov '09

When I use :FORCE, in most cases I do want to recompile solely the specified system, not all its dependencies. In my ideal world, :FORCE T would recompile the specified system only, and :FORCE :ALL would recompile it along its dependencies. Of course that would be backwards-incompatible, so perhaps better stick with the current behaviour for :FORCE T, but add :FORCE :SYSTEM, or :FORCE :SHALLOW, or similiar. -T.

[asdf-devel] patch system-source-file
by Greg Pfeil 25 Sep '09

25 Sep '09

Here are a couple changes to ASDF that I made in the process of creating an ASDF browser for CCL's IDE: • system-source-file now works for systems without their own .asd • optional parts of systems (version, maintainer, etc.) don't leave their slots unbound

[asdf-devel] Small fixup of bogus function in directory-pathname-p
by Joyce Chen 21 Jul '09

21 Jul '09

Fare's small fixup of bogus function in directory-pathname-p. ccl complained about x not being used. I don't have commit privileges, so if someone could kindly review the change and commit it :) Thanks, Joyce diff --git a/asdf.lisp b/asdf.lisp index 1e1118d..714c529 100644 --- a/asdf.lisp +++ b/asdf.lisp @@ -448,12 +448,11 @@ ways that the filename components can be missing are for i Note that this does _not_ check to see that `pathname` points to an actually-existing directory." - (let ((null-components (list nil :unspecific ""))) - (flet ((check-one (x) - (not (null (member (pathname-name pathname) null-components - :test 'equal))))) + (flet ((check-one (x) + (member x '(nil :unspecific "") :test 'equal))) (and (check-one (pathname-name pathname)) - (check-one (pathname-type pathname)))))) + (check-one (pathname-type pathname)) + t))) #+(or) ;;test

Re: [asdf-devel] [cclan-list] How to depend on a system optionally?

[asdf-devel] Partial patch for ASDF manual
by Robert Goldman 21 Jul '09

21 Jul '09

The existing manual doesn't document ASDF's :weakly-depends-on, an issue which this patch addresses. Two notes about this patch, which characterize it as interim: 1. It would help if I had a better example of the use of :weakly-depends-on. I believe I have the semantics right, but I don't have a good use case (a simple textual discussion is enough of a use case). It's not so much how to use the feature as how people write systems that use the feature. For example, would you write a piece of code that weakly depended on system foo, set up system foo so that it pushed :foo on the *features* and then sprinkle "#+ foo" around your code? It almost seems like we'd want a corresponding construct that would load a file only if some feature was present at system operate time (NOT at the time when the ASDF system definition was read). 2. I found that documenting this exposed a weakness in the ASDF manual's structure. The manual provides a section that documents the grammar, and a section that documents the ASDF object model. There isn't really a section that gives a semantic counterpart to the syntax. One might think that the object model documentation would fill this need, but it doesn't really. :weakly-depends-on is a good example of this hole, because weakly-depends-on is translated either into a component dependency or into nothing, so it has meaning only as part of a defsystem form. We can't describe its semantics in the section on the object model, because there is no object model component that corresponds directly to the weakly-depends-on argument. BTW, line 1319 of asdf.lisp seems to be someone's debugging statement left around. Shouldn't it be excised? diff --git a/asdf.texinfo b/asdf.texinfo index cfef5c6..0d26235 100644 --- a/asdf.texinfo +++ b/asdf.texinfo @@ -338,6 +338,7 @@ option := :components component-list | :output-files method-form | :operation-done-p method-form | :depends-on ( {dependency-def}* ) + | :weakly-depends-on ( {dependency-def}* ) | :serial [ t | nil ] | :in-order-to ( {dependency}+ ) @@ -381,6 +382,30 @@ is equivalent to (:file "c" :depends-on ("a" "b"))) @end lisp +@subsection Weakly-depends-on + +The @code{weakly-depends-on} argument says of the component depended on +``if this component can be found, then impose a dependency, otherwise +ignore it.''

[asdf-devel] Problem with pathnames with name component = ""
by Robert Goldman 20 Jul '09

20 Jul '09

I have found out how this problem has seeped into ASDF --- ASDF-INSTALL, at least the version I have (I am checking now to see if there's an improved version) --- seeds asdf:*central-registry* with pathnames with :name = "". This is done by the directorify function in installer.lisp. Investigating further. Perhaps this behavior should simply be stamped out of ASDF-install....

[asdf-devel] added gitweb access (at last)!
by Gary King 18 Jul '09

18 Jul '09

I just added the sauce to let cl.net's gitweb find ASDF's project. See http://common-lisp.net/gitweb?p=projects/asdf/asdf.git;a=summary and let me know if anything is amiss. -- Gary Warren King, metabang.com Cell: (413) 559 8738 Fax: (206) 338-4052 gwkkwg on Skype * garethsan on AIM * gwking on twitter

[asdf-devel] Apply *read-default-float-format* to lisp files
by Brett van de Sande 18 Jul '09

18 Jul '09

I have some lisp source files that contain some (many) floating point numbers. How can I use asdf to ensure these files are read using (setf *read-default-float-format* 'double-float) without setting *read-default-float-format* globally? Thanks, BvdS
