[External] : Re: java.lang.StringTemplate.RAW is not implicitly imported?

[Jim Laskey]

That is because StringTemplate is in the java.lang package which gets imported automatically: “import java.lang.*”.

Hm. Weird, it seems the class itself is imported by default. This code compiles just fine even without any import statements at all. It does not look right to me. But maybe I'm not using the latest version?

StringTemplate st = null;

For me,
RAW does not need to be imported by default, it's uses is not that frequent, it's more like FMT than STR.

Thank you for pointing that out. We will revise.

Hi team,
Reading the JEP 459 spec, I see this:

The static members STR and RAW declared in the predefined interface StringTemplate, as if the declarations import static java.lang.StringTemplate.STR; andimport static java.lang.StringTemplate.RAW; appeared at the beginning of each compilation unit immediately after any package declaration.
As a result, the names of all  implicitly imported  classes, interfaces and static fields are available as simple names in every compilation unit.

So, I assume this should work:

package test;

public class Example {

    public static void main(String argv[]) {

        int a = 1;
        StringTemplate raw = RAW."\{a}";
    }
}


But I get

java:7: error: cannot find symbol
        StringTemplate raw = RAW."\{a + b}";
                             ^
  symbol:   variable RAW
  location: class Example

java --version
java 22-internal 2024-03-19
Java(TM) SE Runtime Environment (build 22-internal-2023-11-03-1839366.james.laskey.open)
Java HotSpot(TM) 64-Bit Server VM (build 22-internal-2023-11-03-1839366.james.laskey.open, mixed mode, sharing)

This code compiles if I add a static import import static java.lang.StringTemplate.RAW;
STR is available through static import, so it’s only RAW that causes issues.

Could it be a bug in JDK?

Thank you,
Ella Ananeva
