Hello!
With rake, I often find myself doing something like that:
file "custom.iso" => "custom.dir" do |t|
begin
sh "mkisofs -r -V My Install CD' -cache-inodes" +
" -J -l -b isolinux/isolinux.bin" +
" -c isolinux/boot.cat -no-emul-boot" +
" -boot-load-size 4 -boot-info-table" +
" -o #{t.name} #{custom.dir}"
rescue
sh "rm #{t.name}"
raise
end
end
to avoid a broken target lying around.
I wonder whether I am missing something here. Shouldn't rake remove t.name?
I mean, once rake has started to build a target, it is pretty much sure that
the target _have_ to be rebuilt. Thus there's no rason to let a half-baked
target lying around should the build of that target fail.
AFAICS, make removes the target if it fails to build it, too.
What am I missing here? Any suggestions?
