Description Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2011-06-06 06:28:57 UTC
Many of the standard ebuild variables contain lists of items, and those could be specified as bash arrays instead of quoted strings.

Those could be *DEPEND especially. Sometimes one likes to add a comment about a particular dependency listed there, and bash arrays would allow doing that nicely.

For example:

DEPEND="${RDEPEND}
	dev-foo/bar
	>=dev-bar/foo-4"
# bar DEP needed because of configure bug (#nnnnn)
# although upstream states foo-3 is enough, baz-7 forces using foo-4

Could be expressed as:

DEPEND=(
	${RDEPEND[@]}
	# configure bug (#nnnnn)
	dev-foo/bar
	# although upstream states foo-3 is enough, baz-7 forces using foo-4
	>=dev-bar/foo-4
)

Thinking about it more, it will probably be a good idea to introduce alternate grouping character with this since () has to be escaped in bash arrays; for example {}.

Are you still pursuing this?
