Reload while sprinting.
Non-intrusive C/C++ hot-reloading toolchain.
Ondago will allow you to introduce hot-reloading to your project quickly and painlessly.
Non-intrusive means that the code base won't have to drastically change. Only a few lines of code will have to be added, which will have no effect for non-hot-reloading builds. This is accomplished by augmenting the build system.
Ondago follows the host-module hot-reloading pattern. The host contains the base application loop and will continuously run, preserving state. The module is a dynamic library containing actual logic which will be repeatedly patched.
The host and the module will be procedurally generated from the project.
Please read the following documents in the order they are provided. Pay attention to the contents of their directories too.
