Hi, is there a rule to enforce vertical alignment in chains?
E.g. force this

listOf(1, 2, 3, 4).filter { it > 3 }
    .map { it * it }

into this

listOf(1, 2, 3, 4)
    .filter { it > 3 }
    .map { it * it }

Thanks

I think you can use https://pinterest.github.io/ktlint/1.2.1/rules/experimental/#chain-method-continuation

[Emil Kantis]

And then you'd need to set ktlint_chain_method_rule_force_multiline_when_chain_operator_count_greater_or_equal_than to 2

When 1st line of chain does not exceed max line length it remains unchanged. So no vertical alignment in that case.

Did you enable the experimental ruleset or this specific rule,?

[Benoît Liessens]

Above sample is with a list but my actual case is with Either : I want .map{} and .mapLeft{} to be vertically aligned.

[Benoît Liessens]

@Paul Dingemans had only enabled that specific rule.
It does work as excpted with experimental rules enabled.
Thanks
