Yes, it is so. If meant to be part of an api GTest for examplethen use coding conventions that drive their uniqueness. It makes no sense to fight against something like this:. No way of getting rid of it any time soon. A little extra time spent on writing a full function will be repaid with interest. It could be argued that developers are to blame for these errors, not macros. Note: Cross-module dependencies are also described on a general level. However, I think you will agree that this is not the case.

    API documentation for the Rust `poly2tri` crate. This library implements a wrapper for the poly2tri C++ implementation of the constrained Delaunay. Today, I am happy to announce a guest post by Andrey Karpov about the evil of macros.

    Andrey is a Microsoft MVP in the “Developer. When the C++ compiler runs, it first calls preprocessor to find any compiler directives that may be included in the source code.

    The directives begin with the​.
    It makes no sense to fight against something like this:. The following table lists parts of Qt that incorporate code licensed under licenses other than GNU Lesser General Public License LGPL or the commercial license, as well as Qt modules that are only available under a specific license or a version of a license.

    An example of barely readable code is the GCC compiler already mentioned above. For the same purposes, it is much better and safer to use constexpr. If you ever happened to face a project peppered with macros, consisting of other macros, then you are aware of how infernal it is to deal with such a project.

    The likelihood of shooting yourself in the foot will be less, compilers and static analyzers will issue fewer false positives.

    They look like functions, but, in fact, have side effects that are difficult to notice.

    I never thought of macros like this. Parts of the codecs implemented by Qt. The documents below list related documents, such as information about Trademark and other licenses used in parts of Qt. See Licenses Used in Qt for details.

    In most cases, using macros is bad practice in C++.

    However, in some cases macros let us write more expressive and correct code.

    Once a program starts to handle longer strings and the number of loop iterations increases, the stack can just end at the most unexpected moment. MIT callgrind. The hitch with macros is that analyzers just cannot differentiate correct sly code from the erroneous code. I never thought of macros like this. For example, the substitution of the isspace function with the following macro:.

    This is what the article is about.

    Almost always you can write an ordinary function instead of a macro. Provides additional information about the licensing of run-time dependencies of Qt for Android. Thoughtless use of macros is one of the ways to write code tended to has bugs. The chan argument is used in the macro without wrapping in parentheses. Such macros, as A2W, hide evil inside.
