[pacman-dev] [PATCH] handle arch specific attributes
by Dave Reisner 31 Jul '14

31 Jul '14

This introduces support for architecutre-specific conflicts, depends, and optdepends by appending "_$CARCH" to the array name. For example, in the global section: arch=('i686' 'x86_64') depends=('foo') depends_x86_64=('bar') This will generate depends of 'foo' and 'bar' on x86_64, but only 'foo' on i686. Moreover, this is supported in the package functions with the same heuristics as the generic names, e.g. ... arch=('i686' 'x86_64') depends=('foo') ... package_somepkg() { depends_x86_64=('bar') ... } Again, will cause x86_64 to have depends of 'foo' and 'bar', but only 'foo' for i686. --- So, what it *doesn't* yet support is arch-specific sources. This is strictly an optimization and only applies to packaging of binary blobs so, personally, I'm okay with this lingering for another patch. If we're okay with the syntax and the way this operates, I can follow up with the documentation side of things. scripts/makepkg.sh.in | 20 +++++++++++++++++++- 1 file changed, 19 insertions(+), 1 deletion(-) diff --git a/scripts/makepkg.sh.in b/scripts/makepkg.sh.in index e20b707..06c7374 100644 --- a/scripts/makepkg.sh.in +++ b/scripts/makepkg.sh.in @@ -1487,6 +1487,22 @@ source_safe() { shopt -s extglob } +merge_arch_attrs() { + local attr supported_attrs=(conflicts depends optdepends) + + for attr in "${supported_attrs[@]}"; do + eval "$attr+=(\"\${${attr}_$CARCH[@]}\")" + done + + # ensure that calling this function is idempotent. + unset -v "${supported_attrs[@]/%/_$CARCH}" +} + +source_buildfile() { + source_safe "$@" + merge_arch_attrs +} + run_function_safe() { local restoretrap @@ -1905,6 +1921,8 @@ write_pkginfo() { local size="$(@DUPATH@ @DUFLAGS@)" size="$(( ${size%%[^0-9]*} * 1024 ))" + merge_arch_attrs + msg2 "$(gettext "Generating %s file...")"
