Task #3895
Updated by Davide Pesavento over 4 years ago
Clang-format is a tool that reformats C++ code (among other languages) according to a configuration file. The program is expressive and useful, and it would be a good extension to the toolchain. Currently, the system has some limitations. According to Davide Pesavento: * ~~"break-after-return-type" "break-after-return-type" doesn't work on overloaded operators, they are not considered functions, thus the rule isn't applied.~~ FIXED in clang-format-10 applied. * `constexpr`/`explicit`/`virtual` are not considered return types (and rightly so), but this means that constexpr/explicit constructors and virtual destructors are reformatted all on one line. This is minor and I think we can adapt our code style. * In lambda expressions, clang-format always removes the space between capture list and param list. This is very minor and we can adapt our style. * clang-format gets *very* confused by macros such as `PUBLIC_WITH_TESTS_ELSE_PRIVATE` (I guess it doesn't expand them) and it makes a terrible mess with the lines that follow, until it encounters another access specifier or the end of the class declaration. * The alignment of "`<<`" after a line break within a logging macro is not what you would expect. * Enums containing few short enumerators that could fit in one line are reformatted to be all on the same line (but there is a [workaround](https://stackoverflow.com/a/24009906))
