Hi all,
Last week I quietly released v0.1.0 of cabal-macosx, providing support
for building OSX application bundles (e.g. and in particular for GUIs
created using wxHaskell and gtk2hs - hence all the cross-posting):
http://hackage.haskell.org/package/cabal-macosx
I'm now soliciting input on how to handle the install stage, leading
(I hope) to a loudly-announcable release soon. :-)
The current package provides a post-build hook which creates an
application bundle at dist/build/foo.app (for example). It seems to
work well. See the source repository for examples.
However, running "runghc Setup install" copies the bare executable at
dist/build/foo/foo (rather than the foo.app bundle) to the install
location, which is no good. So I need to put in some install
infrastructure to copy the .app, not the bare executable, to the right
place.
That raises the question: what is the right place? It seems to me
that the defaults are not the right defaults for this case. --global
should probably go to /Applications, and --user should perhaps go to ~/
Applications (though I'm less sure about that). Of course, end-users
can explicitly set this on a per-install basis, but it seems that for
bundles we'd want to override the default.
Thus I'm currently asking:
* What do people think about the default installation question?
* Can anyone advise me on the right way to handle this (installing
the .app, and overriding the default locations) with Cabal? I'm
hoping I can just tweak part of the LocalBuildInfo and let the default
machinery then handle the work, but at present it's not clear to me
how to do that, and rather than spend ages trying to figure it out,
perhaps someone who knows can help me out? I'm hoping I'm not going
to have to completely override the install machinery - that would feel
somewhat self-defeating.
Many thanks,
-Andy
