modules

So far, I have written in my last four posts the basics you should know about modules in C++20. Only a few questions to modules are still open. In this post, I address these open questions, such as templates in modules, the linkage of modules, and header units.

When your module becomes bigger you want to divide its functionality into manageable components. C++20 modules offer two approaches: submodules and partitions. Let me discuss both approaches in this post.

Thanks to the module interface unit and the module implementation unit, you can separate the interface from the implementation when defining a module. Let me show, how.

Modules are one of the four prominent features of C++20. They overcome the restrictions of header files and promise a lot: faster build-times, fewer violations of the One-Definition-Rule, less usage of the preprocessor. Today, I want to create a simple math module.

Modules are one of the four big features of C++20: concepts, ranges, coroutines, and modules. Modules promise a lot: compile-time improvement, isolation of macros, the abolition of header files, and ugly workarounds.

 My last post gave you the introduction to modules in C++20. This post shows, how to use existing modules.

Modules is one of the five prominent features of C++20. Modules will overcome the restrictions of header files. They promise a lot. For example, the separation of header and source files becomes as obsolete as the preprocessor. In the end, we will also have faster build times and an easier way to build packages.
