Previously, how we handle
binpack.callSite=true
depended only onoptIn.configStyleArguments
, anddanglingParentheses.callSite
was ignored completely.Also, the declared
scala.js
style, which purported to depend on the existence of a break before closing parenthesis, wasn't properly done.Both opening and closing parentheses were output tucked in all cases but one, when both of them were dangling in the input (and the choice of whether to dangle or tuck depended solely on
configStyleArguments
).Now let's introduce a small modification, so that we can express more formatting alternatives, and fix
scala.js
style.Specifically, associate the two variants above with dangling parentheses in the disabled state.
When it's enabled, determine whether to tuck or dangle on break before closing parenthesis. Also, apply config style when that parenthesis is dangling and
configStyleArguments
is disabled (because in the enabled state, it requires both parentheses to be dangling to be triggered).
