    The file is light on rationale but the reason for each addition is detailed in the commit log

      Clang has a flag that will emit warnings for some of these (the string functions for sure.)

      It occurs to me that there ought to be a safer/saner string library for C, sorta like a C API for C++ std::string. It’s too bad such a thing never caught on.

      1. 6

        Sds is 99% of the way there. The remainder you would need language support for.

        that reminds me of the banned.h from MS during the SDLC buzz times, the old links are not working anymore, but here is copy: https://github.com/x509cert/banned/blob/master/banned.h

          I’ve never seen preprocessor directives tabbed like that before, is that standard?

          1. 1

            While most code is not like this, it’s not uncommon.

            1. 1

              Yes. The standard requires that the first character of the line be a # to be recognised as a preprocessor directive (so it’s trivial for the preprocessor to differentiate between directives and source code) and then follows the normal C tokenisation rules, where # is a token, include is a token, pragma is a token and so on. C allows an arbitrary amount of whitespace between tokens (e.g. ++ i and ++i are equivalent).

              This is the only way of indenting preprocessor directives that is actually allowed by the standard. clang-format will happily do this for you.

          2. 0

            I cannot decide if this is a good or a bad thing. More power to those who find it useful, personally I don’t.
