Functions

	Fallback demangle implementation for non-GNU toolchains.

Detailed Description

This header defines:

• A small utility function, demangle(), used to turn compiler-specific type names (typically produced by typeid(T).name()) into more readable strings when supported.
• The template class GBase , which centralizes logger construction and lifetime management for derived classes using the CRTP (Curiously Recurring Template Pattern).

Design goals:

• Make logging setup consistent across many derived classes.
• Keep logger ownership explicit and predictable via std::shared_ptr.
• Optionally allow sharing a single logger across multiple objects to reduce overhead.

Notes on demangling:

• When compiled with __GNUG__ (GNU-compatible toolchains), demangling uses abi::__cxa_demangle from <cxxabi.h>.
• On other toolchains, demangle() returns the input name unchanged.

Function Documentation

demangle()

std::string demangle

(

const char *

name

)

On compilers/platforms where GNU-style demangling is not available, this function simply returns the input string unchanged.

This is a deliberate portability choice: the calling code can rely on the function existing everywhere, while still benefiting from readable names where supported.

Parameters

name	A mangled type name, usually produced by typeid(T).name().

Returns

The original name (no demangling performed).
