Do not insert space after arity-0 infix operator, before parens

[georgms]

Configuration (required)

Please paste the contents of your .scalafmt.conf file here:

version = 3.7.12
runner.dialect = scala212
maxColumn = 120

Command-line parameters (required)

When I run scalafmt via CLI like this: coursier launch scalafmt

Steps

Given code like this:

val logger = mock[Logger]
logger.warn(any) shouldDoNothing()

Problem

Scalafmt formats code like this:

val logger = mock[Logger]
logger.warn(any) shouldDoNothing () // Note the extra space after `shouldDoNothing`

Expectation

I would like the formatted output to look like this:

val logger = mock[Logger]
logger.warn(any) shouldDoNothing()

Workaround

–

Notes

Note that shouldDoNothing is an arity-0 macro provided by Mockito Scala:

def shouldDoNothing(): Unit = macro DoSomethingMacro.doesNothing

1. this was already discussed in feat: add more options for DSL #3385.
2. why should arity-0 be treated differently from arity-2?
