pkg.in/lists: archdep suffices for pkglists This is an initial implementation of architecture dependent contents handling for package lists more or less in the vein of mkimage-profiles-desktop's one *but* using suffix part to filter words in or out *not* prefix part to replace it with a comment marker (thus filtering out lines). The syntax should be pretty obvious: a b@i586 c@x86_64 will get "a b" given ARCH=i586 and "a c" given ARCH=x86_64; please see doc/archdep.txt for a more elaborate description and a conversion script.

== Архитектурно-зависимые фрагменты ==
=== Makefile ===
Достаточно воспользоваться ifeq/ifneq, сравнивая $(ARCH) с нужным:
ifeq (x86_64,$(ARCH))
EFI_LISTS := $(call tags,base efi)
endif
При необходимости сравнить со списком ("любой x86") можно сделать так:
ifeq (,$(filter-out i586 x86_64,$(ARCH)))
use/x11/xorg: use/x11 use/x11/intel use/firmware
else
use/x11/xorg: use/x11
endif
В рецептах (shell-часть Makefile) используйте $(ARCH) или $$ARCH.
=== скрипты ===
В скриптовых хуках ({image-,}scripts.d/*) проверяйте $GLOBAL_ARCH.
=== списки пакетов ===
Бывает так, что в списке пакетов есть смысл упоминать какой-либо из них
только для определённой архитектуры (например, wine или steam); в таких
случаях можно воспользоваться механизмом подстановки, который пословно
обрабатывает списки и в случае наличия суффикса @ARCH оставляет только
слова, в которых этот суффикс соответствует заданной архитектуре сборки.
Например, для Simply Linux в mkimage-profiles-desktop есть строчки:
archdep.txt: these are quotes Build process would choke on "unescaped" stuff otherwise, and these blocks should be blockquotes in the first place.

В случае mkimage-profiles они должны выглядеть так:
archdep.txt: these are quotes Build process would choke on "unescaped" stuff otherwise, and these blocks should be blockquotes in the first place.

Для преобразования можно воспользоваться следующей командой:
