Summary: Code auto formatting for lambda arrows
Key: NETBEANS-3973
URL: https://issues.apache.org/jira/browse/NETBEANS-3973
Project: NetBeans
Issue Type: Bug
Components: java - Editor
Affects Versions: 11.3
Environment: Arch Linux and the included "jdk11-openjdk" package,
official NB 11.3 bin download
Reporter: Bernd Michaely
Since NB 11.3, code auto formatting for lambda errors is broken. NB adds an
additional space before the lambda arrow. To reproduce the problem choose
Menu Tools -> Options -> Editor -> Formatting ->
Language: Java
Category: Wrapping ->
- "Lambda Arrow" : Never
- Check "Wrap After Lambda Arrow"
Category: Spaces -> Around Operators
-> "Lambda Arrow" unchecked:
{{11.2: BinaryOperator plus = (a, b)->a+b;}}
{{11.3: BinaryOperator plus = (a, b)_->a+b;}}{{}}
-> or "Lambda Arrow" checked:
{{11.2: BinaryOperator plus = (a, b) -> a+b;}}
{{11.2: BinaryOperator plus = (a, b)_ -> a+b;}}{{}}
... the underscore chars indicating the additional space char.
Note, that the additional space only appears, if "Wrap After Lambda Arrow" is
checked.
(This problem causes a lot of noise in Diff and VCS for existing code, so this
is pretty annoying and currently prevents me from upgrading to NB 11.3)
