Overview

Drop-in Rust reimplementation of ‘Layout/EmptyLinesAroundArguments`.

Rust walks the AST, reproduces the stock cop’s ‘on_send` / `on_csend` over every multi-line call (with at least one argument whose receiver and selector share a line), scans each argument’s ‘source_range.begin` and the closing `)`/`]` for a preceding run of whitespace spanning a full empty line, and returns, per offense, the offense line range. Ruby reports the range and removes it, exactly like stock’s ‘corrector.remove(range)`.

The cop has no configuration, so it is always bundle eligible; the offenses come from the per-file bundled run (‘Shirobai::Dispatch`). The autocorrect re-passes re-investigate a fresh `ProcessedSource`, which recomputes the bundle from scratch, so this cop keeps no cross-pass state.

.bundle_args(_config) ⇒ Object

No packed configuration: the cop contributes nothing to the bundle’s ‘(nums, lists)` wire format. Kept for symmetry with the other wrappers.
