RuntimeCompiledCPlusPlus VS semver

hscpp (Hotswap C++) is an experimental library I created which allows you to hot-reload C++. It was heavily inspired by Runtime Compiled C++, and works by linking DLLs into your project at runtime.

The only recent attempt to make something like this practical, as far as I know, was RCCpp. Going by the GH activity, it looks like it kind of went nowhere.

FYI I maintain a list of runtime compiled C++ approaches on this wiki: https://github.com/RuntimeCompiledCPlusPlus/RuntimeCompiledCPlusPlus/wiki/Alternatives

There is https://github.com/RuntimeCompiledCPlusPlus/RuntimeCompiledC...

The idea is to use virtual functions, and recompile new classes into a shared library. The shared lib is linked into the running program, and old instances of the classes are deleted and replaced by new instances constructed from the share library.

I am working on a library using the same (stolen) idea here:

hscpp is still very alpha, and I’m sure I’ll find lots of bugs as I work on a “real” demo. In contrast, Runtime Compiled C++ is quite mature and is used in real game projects.

Note that this approach very much limits your architecture. For example, you won’t be able to use statics, as the newly compiled shared libraries won’t see them.

It’s a finicky thing, worth it to me, but not something you can just plop in to an established project.

Well of course it's possible to generate executable code at runtime in C++ since clang itself is written in C++, but it's definitely a much larger undertaking, but there's two such efforts I know of, Cling and RuntimeCompiledCPlusPlus.

Semantic Versioning: for every update (major, minor, or patch) made, increment the version number according to semantic versioning.

npm automates the process of installing, updating, and managing dependencies, which helps to avoid "dependency hell." It supports semantic versioning (semver) that automatically handles patch and minor updates without breaking the existing code, thus maintaining stability across projects. npm also provides the capability to run scripts and commands defined in package.json, which can automate common tasks such as testing, building, and deployment.

We are pleased to introduce Semantic Versioning and release channels to Snyk CLI from v.1.1291.0 onwards. In this blog post, we will share why we are introducing these changes, what problems these changes solve for our customers, and how our customers can opt-in according to their needs.

Following the Semantic Versioning rules, you should raise the version number every time you need to publish your library. In your "package.json" file, you need to change the version number to reflect whether the changes are major, minor, or patch updates.

Semantic Versioning: An established convention for version numbers following the pattern MAJOR.MINOR.PATCH

Increases the major of the latest tag and prints it As per the Semver spec, it'll also clear the pre-release…

The reason for this is that software libraries and package managers, in general, but specifically here, rely on semantic versioning. Semantic versioning is really useful for distributing packages in a predictable way. What does this look like for our project?

I believe neovim follows semantic versioning. https://semver.org/

Semver has been 2.0.0 for 10 years, look at the date of the assets. Multiple releases created today where none existed before. Not sure why someone is creating releases now, perhaps just some housekeeping/cleanup.
