From: Chris Larson <chris_lar...@mentor.com> This includes some utility functions for dealing with groups of packages defined in the metadata. Metadata syntax:
PACKAGE_GROUP_<group> = "<list of packages>" If the packages in the group are optional: PACKAGE_GROUP_<group>[optional] = "1" Signed-off-by: Chris Larson <chris_lar...@mentor.com> --- meta/classes/base.bbclass | 2 +- meta/lib/oe/packagegroup.py | 29 +++++++++++++++++++++++++++++ 2 files changed, 30 insertions(+), 1 deletions(-) create mode 100644 meta/lib/oe/packagegroup.py diff --git a/meta/classes/base.bbclass b/meta/classes/base.bbclass index 7950bc3..8f4ef1e 100644 --- a/meta/classes/base.bbclass +++ b/meta/classes/base.bbclass @@ -10,7 +10,7 @@ inherit metadata_scm inherit buildstats inherit logging -OE_IMPORTS += "os sys time oe.path oe.utils oe.data" +OE_IMPORTS += "os sys time oe.path oe.utils oe.data oe.packagegroup" OE_IMPORTS[type] = "list" def oe_import(d): diff --git a/meta/lib/oe/packagegroup.py b/meta/lib/oe/packagegroup.py new file mode 100644 index 0000000..b04c45a --- /dev/null +++ b/meta/lib/oe/packagegroup.py @@ -0,0 +1,29 @@ +import itertools + +def is_optional(group, d): + return bool(d.getVarFlag("PACKAGE_GROUP_%s" % group, "optional")) + +def packages(groups, d): + for group in groups: + for pkg in (d.getVar("PACKAGE_GROUP_%s" % group, True) or "").split(): + yield pkg + +def required_packages(groups, d): + req = filter(lambda group: not is_optional(group, d), groups) + return packages(req, d) + +def optional_packages(groups, d): + opt = filter(lambda group: is_optional(group, d), groups) + return packages(opt, d) + +def active_packages(features, d): + return itertools.chain(required_packages(features, d), + optional_packages(features, d)) + +def active_recipes(features, d): + import oe.packagedata + + for pkg in active_packages(features, d): + recipe = oe.packagedata.recipename(pkg, d) + if recipe: + yield recipe -- 1.7.1 _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
