Overview

Drop-in Rust reimplementation of Style/NestedParenthesizedCalls.

Detection and autocorrect both happen in Rust; Ruby turns the byte offsets handed back into offenses and corrector ops. The corrector builds an range_with_surrounding_space(side: :left) analogue ([ac_open_start, ac_open_end) → () plus an insert_after at ac_close_pos, matching stock byte-for-byte.

AllowedMethods is taken from the cop's own config (plus the deprecated IgnoredMethods / ExcludedMethods aliases for parity with stock's AllowedMethods mixin). Regexp entries are not supported on the bundle path; if any regexp is configured, the wrapper falls back to the standalone per-cop call instead.

def self.badge = RuboCop::Cop::Badge.parse("Style/NestedParenthesizedCalls")

.bundle_args(config) ⇒ Object

Returns [allowed_methods]. allowed_methods mirrors the stock AllowedMethods mixin: AllowedMethods + deprecated IgnoredMethods

  • ExcludedMethods, with Regexp entries dropped (the bundle path accepts string names only). When any regexp is present bundle_args still returns the strings; the wrapper detects the regexp in bundle_eligible? and uses the standalone path instead.
