Overview

Drop-in Rust reimplementation of Layout/SpaceBeforeComma.

Stock walks sorted_tokens pairwise (SpaceBeforePunctuation); Rust reconstructs the same facts byte-side: a comma token is a , byte outside strings / symbols / regexps / comments / heredoc bodies / $, / __END__ data, and the previous token's end is the first non-whitespace byte to the left on the same line. A block or lambda { right before the comma is skipped when Layout/SpaceInsideBlockBraces wants a space after it (space_required_after_lcurly? — unreachable for commas in code that parses, but mirrored for exactness).

Each offense is the [start, end) whitespace run before the comma; the corrector removes it (PunctuationCorrector.remove_space).

def self.badge = RuboCop::Cop::Badge.parse(cop_name)

.bundle_args(config) ⇒ Object

Packed args for the bundled run: [Layout/SpaceInsideBlockBraces EnforcedStyle == 'space'] (nil falls back to 'space', like stock's space_required_after_lcurly?).
