Adds a
duplicated-codecommand - a small token-based copy-paste detector, a clone of phpcpd.It tokenizes PHP with
token_get_all(), strips whitespace and comments, then finds exact duplicate token spans with a Rabin-Karp rolling hash.Extracted from the
utils/duplicatesscript in rector-src so it can be reused across the rector packages CI.Options:
--min-linesminimum lines of a reported clone (default 5)--min-tokensminimum tokens of a reported clone (default 70)--fuzzyignore variable names when matching--skip-filefile paths or masks to skipExit code is 1 when clones are found, 0 otherwise.
