Regarding multiline-expression-wrapping rule: Why is the code formatted differently based one whether the expression is assigned to a variable or to a function argument? This looks a little bit inconsistent to me.

[Paul Dingemans]

The code sample on the right, is not the way it is formatted for me. That one should be indented as well (at least in code style ktlint_official). So it might be related to your configuration. Can you provide your .editorconfig and the code sample (not as image)?

[David Kubecka]

Yes, this happens only of the code style is intellij_idea. So perhaps it's actually a different rule causing the (mis)alignment?

[Paul Dingemans]

No, the code on the right is the default formatting of Intellij IDEA. It is actually one of the reasongs why ktlint_official code style was created.

[David Kubecka]

Ok, so perhaps there's just a minor mistake in the docs. It says that the indent rule (which should be responsible for this) has the same settings in both intellij_idea and ktlint_official styles. In reality the formatting is different in those two cases.

[Paul Dingemans]

That is correct. There are differences between the two code styles in the indent rule. Those are not configurable though.

[David Kubecka]

So should those differences perhaps be mentioned in the doc?

[Paul Dingemans]

It is almost impossible to document every edge case in the documentation without writing an entire book. That is why the documentation of this rule also refers to the unit tests. The unit tests for the indent rule is currently 5500+ LOC...
