[jira] [Created] (GROOVY-9324) Implement `AstStringCompiler` in
Java
Daniel Sun created GROOVY-9324:
----------------------------------
Summary: Implement `AstStringCompiler` in Java
Key: GROOVY-9324
URL: https://issues.apache.org/jira/browse/GROOVY-9324
Project: Groovy
Issue Type: Improvement
Reporter: Daniel Sun
Assignee: Daniel Sun
Fix For: 3.0.0-rc-2
We can use {{AstStringCompiler}} to construct AST in Java code, it will be especially useful when we want to implement {{ASTTransformation}} and generate complicated bytecode. For example,
{code:java}
AsmClassGenerator acg = controller.getAcg();
// Using text block in Java 13(preview)
new AstStringCompiler().compile("""
if ('a' == x) {
...
} else {
...
}
""", CompilePhase.CONVERSION, true).get(0).visit(acg);
{code}
So we do not have to contruct AST with util methods of {{GeneralUtils}} any more.
