Consider this code:
object Delegate {
operator fun getValue(t: Any?, p: KProperty<*>): String {
return ""
}
}
class A {
val String.ext by Delegate
}
then the type of <p> is KProperty2 (it has 2 receivers).
Test fix + review fixes
Pass it in the CompilerConfiguration instead of LanguageVersionSettings.
This is better because LanguageVersionSettings is accessible everywhere
in front-end and back-end, and this flag should not be used there
Previously there were three LanguageFeature instances -- Coroutines,
DoNotWarnOnCoroutines and ErrorOnCoroutines -- which were handled very
awkwardly in the compiler and in the IDE to basically support a language
feature with a more complex state: not just enabled/disabled, but also
enabled with warning and enabled with error. Introduce a new enum
LanguageFeature.State for this and allow LanguageVersionSettings to get
the state of any language feature with 'getFeatureSupport'.
One noticeable drawback of this approach is that looking at the API, one
may assume that any language feature can be in one of the four states
(enabled, warning, error, disabled). This is not true however; there's
only one language feature at the moment (coroutines) for which these
intermediate states (warning, error) are handled in any way. This may be
refactored further by abstracting the logic that checks the language
feature availability so that it would work exactly the same for any
feature.
Another issue is that the difference among ENABLED_WITH_ERROR and
DISABLED is not clear. They are left as separate states because at the
moment, different diagnostics are reported in these two cases and
quick-fixes in IDE rely on that
Inject LanguageVersionSettings instead; all information relevant to the
analysis should be now passed via an instance of LanguageVersionSettings
(which should be renamed to a more general name in the future).
This is partially a revert of d499998 and related commits
This makes it possible to avoid the CompilerConfiguration instance in
injectors, because CompilerDeserializationConfiguration was the only
left component that required it.
LanguageVersionSettings is not a good name for this entity anymore, it
should be renamed in the future
This makes it possible to drop CompilerConfiguration from
CallCheckerContext, which in turn helps to avoid passing the entire
CompilerConfiguration instance through front-end
Previously JvmTarget was declared in module 'util' which is accessible
for example from 'frontend', which is not very good.
Also add a superinterface named TargetPlatformVersion which is going to
be used in platform-independent injectors in 'frontend' in the following
commits. Use it in one place (LanguageVersionSettingsProviderImpl.kt)
instead of DescriptionAware because TargetPlatformVersion sounds like a
better abstraction than DescriptionAware here
Before this change the check was quite complicated
because of cases like:
for (i in 1..9)
foo(i)<caret>
It's not located in a block, but in the same time it's a stament.
So we had a tricky heuristics that if is parent is not a block, then
we should check if element isn't used as expression.
Of course this heuristics is wrong, e.g. for import/package nodes.
The solution is to reuse similar logic from BasicExpressionTypingVisitor.
it has been checked once that statement container is one of:
- KtBlockExpression
- KtContainerNodeForControlStructureBody
- KtWhenEntry
So there's no need to check anything else
#KT-14986 Fixed
#KT-14483 Fixed
Allow to specify predicate by KtExpression instead of type predicate
It will be used for `for` template which need a context to determine
whether the expression is iterable
Added "Unused return value of a function with lambda expression body" inspection with quickfix "Remove '=' token from function declaration"
#KT-10393 Fixed
Inline lambda could capture reified parameter of containing inline function ('a' function)
when it is inlined in another one.
If it's inlined in any anonymous object we should track it and
add reification marker to such anonymous object instance creation
to rewrite it on inlining bytecode of 'a' function.
#KT-15997 Fixed
This would allow building the project with Kotlin JPS plugin on TeamCity where older library takes precendence due to appearing earlier in JPS classpath
