Hi Guillaume,
yes, there seems to be nothing on @Macro.

Did you also check the documentation?

Hi Cedric,
thank you for replying. I did try having the @Macro annotated
in a (static) method in a seperate class first, then moved it
closer to the test. I posted that for brevity, and since I
was banking on the author of the feature to set me straight...
The release notes
(http://groovy-lang.org/releasenotes/groovy-2.5.html
<http://groovy-lang.org/releasenotes/groovy-2.5.html>)
currently have the following to say on the topic:
Macro support
With Groovy 2.5, you can write macros in Groovy!
Expressions and statements
TBD
Macro classes
TBD
AST matching
TBD

I didn't check, but I _think_ you can't define a macro and use
it in the same file.

I would have expected a quick "you can't use it like that
/ you just have to / here is some documentation" reply...
Then let me rephrase my question: Why are these Groovy 2.5
tests green:
https://github.com/apache/groovy/blob/GROOVY_2_5_X/subprojects/groovy-macro/src/test/groovy/org/codehaus/groovy/macro/MacroTransformationTest.groovy
<https://github.com/apache/groovy/blob/GROOVY_2_5_X/subprojects/groovy-macro/src/test/groovy/org/codehaus/groovy/macro/MacroTransformationTest.groovy>
?

Hi guys,
giving the new Groovy 2.5 macro functionality a spin, and
would have expected the code below to replace the "call"
to nv(x) with the AST expression created in the method,
i.e. returning the name of the "passed" variable. Instead
no macro magic happens, and the compilation accordingly
fails with "groovy.lang.MissingMethodException: No
signature of method: groovy.GroovyMacroSpike.nv() is
applicable for argument types: (Integer) values: [123]":
import org.codehaus.groovy.ast.expr.Expression
import org.codehaus.groovy.ast.expr.VariableExpression
import org.codehaus.groovy.macro.runtime.Macro import
org.codehaus.groovy.macro.runtime.MacroContext
import org.junit.Ignore import org.junit.Test import static
org.codehaus.groovy.ast.tools.GeneralUtils.constX
class GroovyMacroSpike {
@Test @Ignore void nvTest() {
final x =123 assert x ==123 assert nv(x) =="x" }
@Macro Expression nv(MacroContext ctx, VariableExpression
variable) {
return constX(variable.getName());
}
}
What is missing to make this work ?
