Trying to see if a property is set in the .properties files

No, it is completely unrelated.

P.S. OK, you can test whether some string literal resolves to some property
e.g. this way:

resolved = literalExpression.findReferenceAt(0).resolve();
return resolved instanceof com.intellij.lang.properties.Property;

Hi!
I'd like to make an inspection to see if a string following a specific
pattern is a key in the project .properties files.

(for example if you have someMethod("project.str1"), and there is no
project.str1=foo in any .properties files, this inspection would notify a
problem.

How can I see if a string is a key in the project .properties files?

I saw there's a PropertiesComponent and it has a
isValueSet(java.lang.String name) method. Is it related to my problem, or
something completely unrelated?

Thanks!

Thanks!

However 1/ can I test if a property is set without it being an
expression. For example my expression is "FOO" but I want to see if
"FOO"+"_REQUEST" is set.
2/ I can seem to find the com.intellij.lang.properties package anywhere ?

3/ expression.findReferenceAt(0) always returns null even when the
String is indeed a key in a property file (middle-click does work and
goes to the declaration in the file)

Sorry, it meant to be PsiReference ref =
literalExpression.findReferenceAt(1);, since the first element in the string
literal is open quote.
Further, there should be these magical lines:

boolean resolvesToProperty(PsiReference ref) {
if (ref instance com.intellij.psi.PsiPolyVariantReference) {
for (PsiReference variantRef:
((PsiPolyVariantReference)ref).multiResolve(false)) {
if (resolvesToProperty(variantRef)) return true;
}
}
return ref.resolve() instanceof Property;
}

As to whether "FOO"+"_REQUEST" expression resolves to the property, there is
public static Collection findPropertiesByKey(Project project, final String key) in the com.intellij.lang.properties.PropertiesUtil class although it is not OpenAPI yet. -- regards, -- Alexey Kudravtsev Software Developer JetBrains, Inc, http://www.jetbrains.com "Develop with pleasure!"

Thank you very much I used the findPropertiesByKey way, and it works well.
I think I'm gonna release this inspection since I believe it could be
usefull.
