From 08a8043f1916cb2a337b93b6b6d600df9af6ecb7 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Mon, 22 Feb 2021 17:19:48 +0100 Subject: interpreter: add feature.allowed() This method simplifies the conversion of Feature objects to booleans. Often, one has to use the "not" operator in order to treat "auto" and "enabled" the same way. "allowed()" also works well in conjunction with the require method that is introduced in the next patch. For example, if get_option('foo').require(host_machine.system() == 'windows').allowed() then src += ['foo.c'] config.set10('HAVE_FOO', 1) endif can be used instead of if host_machine.system() != 'windows' if get_option('foo').enabled() error('...') endif endif if not get_option('foo').disabled() then src += ['foo.c'] config.set10('HAVE_FOO', 1) endif Signed-off-by: Paolo Bonzini --- mesonbuild/interpreter/interpreterobjects.py | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'mesonbuild/interpreter/interpreterobjects.py') diff --git a/mesonbuild/interpreter/interpreterobjects.py b/mesonbuild/interpreter/interpreterobjects.py index c70b8b5..5a37b48 100644 --- a/mesonbuild/interpreter/interpreterobjects.py +++ b/mesonbuild/interpreter/interpreterobjects.py @@ -72,6 +72,7 @@ class FeatureOptionHolder(InterpreterObject, ObjectHolder[coredata.UserFeatureOp self.name = name self.methods.update({'enabled': self.enabled_method, 'disabled': self.disabled_method, + 'allowed': self.allowed_method, 'auto': self.auto_method, }) @@ -87,6 +88,11 @@ class FeatureOptionHolder(InterpreterObject, ObjectHolder[coredata.UserFeatureOp @noPosargs @permittedKwargs({}) + def allowed_method(self, args, kwargs): + return not self.held_object.is_disabled() + + @noPosargs + @permittedKwargs({}) def auto_method(self, args, kwargs): return self.held_object.is_auto() -- cgit v1.1
