[asdf-devel] Didn't you fix this bug?

2011-03-23 Thread Robert Goldman
I believe you have already not just committed, but released, a fix, and
we also have a test now.

https://bugs.launchpad.net/asdf/+bug/732317

Want to clear this (credit where credit is due)?

If you don't have time, drop me a line, and I can.

cheers,

It's complex and underpowered, and underdocumented. Some report
getting it to work, others report failing to make it work. We're
trying to support existing practice, but I'm not sure we encourage it
at this point. You're welcome to document it after you get it to work.


[Removing my hat of ASDF maintainer]
Personally, I prefer the XCVB way of doing things:
* having a module bar under build foo doesn't necessarily mean that
 building foo depends on bar - just that you can name and find bar under foo.
* build foo starts includes a list of direct dependencies;
 other dependencies are found recursively
* the dependency language has conditionals, and a sublanguage for features,
 so you may depend on
  (:when (:featurep :sbcl) "cmu-descendant-addon1" "sbcl-addon2")

Note that this goes contrary to the current ASDF design, so it's not trivial
to import ideas from XCVB into ASDF.

The good news is that XCVB works, and that it's easy to mix and match
between ASDF and XCVB. The bad news is that it currently only
supports three implementations, on Unix only, so isn't ready
to supplant ASDF yet.

Wasn't there a bug where we said "we should not make people implement
conditional branching by means of exception handling" (which is really
what :if-component-dep-fails is used for)?  I couldn't find it...  If
there isn't one, we should probably add such as an enhancement.  Saying

(:when )

is probably a lot better than trying to grok an :if-component-dep-fails
policy

[asdf-devel] Status of :feature

2011-03-23 Thread Didier Verna

  Hello,

what is the current status of :feature in a list of dependencies? I
mean, is it safe to replace #+ reader conditionals in the asd file with
it?

Thanks.
