* Fix shell variable comparison without $CI present + '[' = true ']' ./tests/restyle.sh: line 16: [: =: unary operator expected vs. + '[' '' = true ']' * Update to clang-format-18 new opt to skip overly eager macro formatting https://clang.llvm.org/docs/ClangFormatStyleOptions.html#skipmacrodefinitionbody minor changes between 15 and 18 for ide examples reference arduino-ide format is still stuck with 15, though https://github.com/arduino/clang-static-binaries/releases * Pin clang-format in CI recipe not the script itself * style
