Overview

Drop-in Rust reimplementation of ‘Style/LineEndConcatenation`.

Rust detects string literal concatenations broken across lines with ‘+` or `<<` and computes the autocorrection range. Ruby reports the offense and replaces the operator (plus trailing whitespace) with ``. Offenses come from the per-file bundled run (`Shirobai::Dispatch`); the cop has no configuration, so it is always bundle-eligible.

Constant Summary collapse

MSG = 
"Use `\\` instead of `%<operator>s` to concatenate multiline strings."
