Re: [jdt-dev] Using var keyword with Java 8 target
|
Well the patch itself is trivial... this should actually work
Hi Stefan,
ecj is released standalone as well as the batch compiler - see https://download.eclipse.org/eclipse/downloads/drops4/R-4.19-202103031800/ [This link is from https://download.eclipse.org/eclipse/downloads/ and click 4.19]
Under this look for JDT Core Batch Compiler - you can download ecj from there.
Regards,
Manoj

Nevermind, I found it. I was just working on an older version of ecj (4.5.2 - it's not released standalone anymore, is it?). I found the "var" stuff in JDT core R4_19. On Mon, 5 Apr 2021 at 11:51, Stefan Reich <stefan.reich.maker.of.eye@xxxxxxxxxxxxxx ZjQcmQRYFpfptBannerStart

Hmm, could you point me to where in the compiler the "var" keyword is handled? I'm happy to patch things myself :)
Thanks

Hi Stefan,
You are right that var is at compiler level since the type is inferred by the compiler.
However, since var was introduced at Java 10 as per the language specification, we cannot provide var at Java 8 level.
Thanks,
Manoj

Hi,
the "var" keyword is solely implemented on the compiler level, yes? So then, is it possibly to give an ECJ compiler flag that allows me to use the var keyword in code compiled for Java 8?
I'd really like to keep Java 8 compatibility, but the var keyword is so incredibly convenient...
Greetings,
Stefan
