Macros
#define	BOOL_TOGGLE(lval)   ((lval) = ((!(lval)) != 0))
	Toggle a bool lvalue (equivalent to x = !x).

	Convert a bool to int explicitly.
#define	INT_TO_BOOL(expr)   ((expr) != 0)
	Convert an int expression to bool explicitly.

Detailed Description

Portable bool↔int conversion macros for clang-tidy compliance.

C's ! operator, ||/&&, and ternary conditions return int, which triggers readability-implicit-bool-conversion when assigned to or used with bool fields. These macros centralize the casts so the workaround lives in one place and can be revisited if C23 or a future clang-tidy relaxation removes the need.

Macro Definition Documentation

BOOL_TO_INT

#define BOOL_TO_INT

(

b

)

((int)(b))

Convert a bool to int explicitly.

Use in ternary conditions, arithmetic expressions, and GPU uniform uploads where an int/GLint/int32_t is expected from a bool source.

BOOL_TOGGLE

#define BOOL_TOGGLE

(

lval

)

((lval) = ((!(lval)) != 0))

Toggle a bool lvalue (equivalent to x = !x).

!x returns int in C; direct assignment to bool triggers the check.

INT_TO_BOOL

#define INT_TO_BOOL

(

expr

)

((expr) != 0)

Convert an int expression to bool explicitly.

Use for external API returns (GLFW, OpenGL) and logical OR/AND chains assigned to a bool variable.
