Using if constexpr to check if a type is in the typelist (C++17) Live Demo Part 1: a unique typelist: Again, all credit to @Deduplicator's answer here on this part. The following code saves compile-time performance by doing lookups on a typelist in O(log N) time thanks to leanin...
However, the compiler (GCC latest) doesn't like binder being used in the constructor, as this isn't necessarily known at compile-time, though I know that instances of MyClass will only be declared at compile-time.C++20 introduced consteval functions (and constructors) which "must...

${CMAKE_CURRENT_BINARY_DIR}/version.cpp to the list of files in my build.This works beautifully: whenever I run a build, it checks the state of the repo and writes a new copy of version.cpp if things have changed. In turn, if that file is modified, then the usual compilation ...
9. For example, most C compilers improve runtime efficiency by folding constant expressions during compile time. 例如,大多数C编译器改善折叠在编译时间常数表达式的运行效率。 10. compile的反义词 10. If DOS mount high memory, so that some of the driver is loaded in upper memory area, that is,...
The name of a method in a form.RemarksThis is a compile-time function. For more information, see Overview.ExampleThe following example prints the name of the showDialog method.X++ Copy str c = formMethodStr(Batch,showDialog); formStr...
Fast compile-time regular expressions with support for matching/searching/capturing during compile-time or runtime. You can use the single header version from directory single-header. This header can be regenerated with make single-header. If you are using cmake, you can add this directory as ...
In this scenario, a compiler uses reflection emit tocompileregular expressions in source code. 在此方案中, 编译器使用反射发出编译源代码中的正则表达式. 期刊摘选 Manage complete jig in escalator factory, andcompileoperation manual and maintenance instruction about jig. ...
constexpr-8ccis a compile-time C compiler implemented as C++14 constant expressions. This enables you tocompile while you compile!This project is a port of8ccbuilt onELVM Infrastructure. Constant expressions in C++are expressions that can be evaluated at compile-time. In C++14,by relaxing constra...
compile time. The second function,getCompileTimeValue, returns the value of a named argument, or a default value in case the argument is not specified at compile time, as a string. The third function,getCompileTimeListValue, is similar to the first function, but it expects the value to be...
