@echo off
REM Applies clang-format and clang-tidy's --fix across this project's own
REM C/C++ code. The pre-commit hook only CHECKS; this is the "just fix it"
REM counterpart -- review the result with `git diff` afterward, same as any
REM auto-formatter.
REM
REM Defaults to source\ and c-api\, this template's own-code roots -- NEVER
REM walks out\, .cache\, vendor\, or .git\ by default, so it can't
REM accidentally spend minutes reformatting/analyzing a fetched dependency's
REM entire source tree the way scanning the whole repo from "." would.
REM
REM Usage, from the project root: scripts\refactor.bat [optional path]
REM   scripts\refactor.bat              every file under source\ and c-api\
REM   scripts\refactor.bat source\HotReload  just one file or directory --
REM                                     taken as given, with no exclusion
REM                                     filter, so pick a path that doesn't
REM                                     overlap with out\/.cache\/.git\

REM Collect the file list. Deliberately NOT using an if/else block here --
REM a for /f or for /r loop nested inside a parenthesized if(...) else(...)
REM block confuses cmd.exe's paren-matching for the enclosing block (this
REM was tested and confirmed, not a guess); goto-based branching sidesteps
REM the problem entirely by never nesting a FOR loop inside another block.
