An opinionated, header-only debugging helper and logging library for Unreal. This library is intended to be owned instead of being treated as third-party code. There are no releases or versions. Don't even fork or clone this repository. Download the .h, copy it into your project, rename things, make it yours!
- Less than 250 lines of self-documenting code, including the license.
- Three hardcoded debug levels: debug, warning, error.
- Per-file runtime control of debug levels with CVars.
- Logging macros using the well-documented, standard std::format syntax.
- if macros to keep your debug draws in sync with the logs.
- Everything gets written to UE_LOG and AddOnScreenDebugMessage.
- Support for Unreal types: you can log FStrings without the operator* hack, FVector is supported directly, UObjects are logged as their class and name, etc.
- Supports Unreal and STL-style containers and tuples, with arbitrary nesting.
- Adding your own handlers is as simple as continuing an else if constexpr chain.
- Compile-time format string checking, courtesy of std::format itself.
- Bad runtime performance. Still better than BP and it gets compiled to nothing in Shipping anyway.
- Incompatible with unity builds.
